Two magnetic pumps, the same sealless drive principle, the same stainless steel wetted construction — and two different jobs. This head-to-head compares the YUAN SHIN PUMP MAP-18A regenerative turbine magnetic pump and the CAP-100 stainless steel centrifugal magnetic pump on the criteria that actually settle a project: duty point, temperature ceiling, certification coverage, customization room, and maintenance economics. The short answer: the MAP-18A is specified for a maximum head of 80–100 m at a maximum capacity of 3.9–7.2 m³/h, while the CAP-100 is specified for a rated head of 15–40 m at a rated capacity of 4–35 m³/h. High head through a small circuit points to the MAP-18A; high volume against modest resistance points to the CAP-100.

Stainless steel magnetic pumps inspected and staged for shipment at YUAN SHIN PUMP — the same 100% test discipline applies to both designs compared in this article.

What This Head-to-Head Has to Decide

A magnetic pump comparison is not a contest between a “better” and a “worse” design. It is a routing decision: which hydraulic family fits the operating point your process actually runs at, and which one you will still be able to maintain, certify, and re-order five years from now.

The two candidates come from the range of YUAN SHIN PUMP — the brand of Yuanxin Pump (Suzhou) Technology Co.,Ltd., a magnetic pump manufacturer with roots in Taiwan Yuanshin (1990), a Guangdong site added in 2001, and the Suzhou plant established in 2014. Both models are sealless magnetic drive pumps built for high-temperature service, and both are covered by the same motor-recognition and management-system certificates. They diverge on hydraulics and on temperature ceiling, and that divergence is what determines the answer.

Four comparison traps account for most mis-selections in this category:

1. Comparing catalogue peaks instead of the operating point. A pump that reaches 100 m at a few cubic metres per hour is not interchangeable with a pump rated for 35 m³/h at 15–40 m, even though both are “stainless steel magnetic pumps.”
2. Ignoring the temperature ceiling. The MAP-18A and the MAP-1100 are specified across −196°C to +400°C; the CAP-100 across −196°C to +350°C. Thermal oil and high-temperature mould circuits can sit precisely in the gap.
3. Assuming certification coverage is identical. The CE certificates in this range are issued against different product descriptions, and the UL recognition applies to the electric motor as a component of complete equipment — not to the pump as a finished machine.
4. Buying on purchase price only. The documented field return in this range comes from eliminating the mechanical seal as a wear part, which shifts the cost balance over a multi-year horizon.

Industry Background: Why Both Designs Are Being Sourced in 2026

The context matters because it explains why buyers increasingly face this exact comparison rather than a simple “pump or no pump” question.

• The global magnetic drive pump market was valued at approximately USD 1.37 billion in 2024 and is projected to grow to USD 2.65 billion by 2033 (Grand View Research).
• Asia Pacific dominated that market in 2024 with a 45.9% revenue share, driven by industrialisation in China and India (Grand View Research).
• Chemical processing remains the leading application segment, estimated at approximately 34.8% to 37% of market share (Fact.MR / Straits Research, 2025).
• Stainless steel accounts for roughly 41% to 48.7% of the material segment, reflecting the priority buyers place on corrosion resistance (Future Market Insights / Straits Research, 2026).
• The narrower regenerative turbine segment was valued at USD 271.1 million in 2025, with a CAGR of 7.3% through 2035 (Future Market Insights).
• Regenerative turbine pumps are increasingly adopted in TCU (temperature control units) for the semiconductor industry because of their high delivery head and compact design (Fact.MR, 2026).
• API 685 is the primary international standard for sealless magnetic drive centrifugal pumps used in heavy-duty petroleum and gas services (American Petroleum Institute).

Read together, these signals describe a market where the growth is not evenly distributed across designs. High-flow centrifugal magnetic pumps absorb the bulk of chemical and process circulation duty, while the turbine family grows where head density and compactness matter more than volume — semiconductor TCU, high-temperature mould control, and laboratory circuits. That is exactly the split this head-to-head has to resolve.

The Two Candidates, in Verifiable Detail

Option A — MAP-18A Regenerative Turbine Magnetic Pump

The MAP-18A is classified in the YUAN SHIN PUMP range as a regenerative turbine magnetic pump and a high-temperature magnetic drive pump, built in stainless steel. Its stated parameters are a power range of 1.1 kW to 2.2 kW, a medium temperature range of −196°C to +400°C, a maximum head of 80–100 m, and a maximum capacity of 3.9–7.2 m³/h.

Its listed application fields are high-temperature mould temperature control, TCU temperature control equipment, industrial manufacturing, chemical pharmacy, semiconductor and precision electronics, semiconductor cooling equipment, research and development and laboratories, ultrasonic cleaning equipment, and chemical equipment. The pattern is consistent: narrow circuits that need pressure, not volume.

Option B — CAP-100 Stainless Steel Centrifugal Magnetic Pump

The CAP-100 is classified as a stainless steel centrifugal magnetic pump and a high-temperature magnetic drive pump, also in stainless steel. Its stated parameters are a power range of 0.75 kW to 11 kW, a medium temperature range of −196°C to +350°C, a rated head of 15–40 m, and a rated capacity of 4–35 m³/h.

Its listed application fields are precision temperature control and mould temperature control equipment, industrial manufacturing, chemical and pharmaceutical, semiconductor and precision electronics, and research and development and laboratories. The pattern here is volume: chiller loops, cooling-water circulation, and general process transfer where flow rate governs the design.

Test run complete with inverted drainage — every unit is verified before it leaves the Suzhou plant, regardless of which hydraulic family is ordered.

Why the Trade-Off Exists

A regenerative turbine impeller accelerates the fluid repeatedly through a peripheral channel, adding energy on each pass. The result is a steep head curve in a compact casing — high pressure at low flow. A centrifugal impeller converts velocity into pressure once, in a larger flow path, which produces a flatter curve with much higher volume. Neither behaviour is an advantage in isolation; each is a mismatch outside its operating window. Specifying a high-head turbine into a high-flow loop means throttling away energy you paid for. Specifying a centrifugal pump into a 90 m circuit means chasing a duty point it was never rated to reach.

What the Certificates Actually Cover

Certification is where head-to-head comparisons most often collapse, because buyers assume a brand-level certificate covers a model-level order. In this range, the documentation is model-specific:

• CE-4067-300425 — CE certificate issued by ECES covering Stainless Steel Vortex Magnetic Pumps, applicable to the MAP-18A and the MAP-1100, issued 2025-04-30 and valid to 2030-04-30.
• CE-4066-300425 — CE certificate issued by ECES covering Stainless Steel High Flow Centrifugal Magnetic Pumps, applicable to the CAP-100, issued 2025-04-30 and valid to 2030-04-30.
• UL-US-2425000-0 — UL Recognized Component certificate for the electric motor as a component used in complete equipment, to UL 1004-1, issued by UL LLC on 2024-07-01, applicable to the US market and to the MAP-18A, MAP-1100 and CAP-100.
• UL-CA-2419643-0 — UL Recognized Component certificate for the electric motor as a component used in complete equipment, to CSA C22.2 NO.100, issued by UL LLC on 2024-07-01, applicable to the Canadian market and to the same three models.
• ISO 9001:2015 (CN-00224Q23283R0S) and ISO 14001:2015 (00224E32265R0S) — issued by China Quality Mark Certification Group (CQM), issued 2024-06-07, valid to 2027-06-06, with scope covering vortex pump and centrifugal pump design development and production.

CE-4066-300425 covers the stainless steel high flow centrifugal magnetic pump range, including the CAP-100.

Step-by-Step: Running the Head-to-Head in Five Steps

Step 1 — Fix the duty point before you look at a catalogue

Write down the required flow and the required head at that flow, not the system maximums. The MAP-18A is a 80–100 m maximum-head design at 3.9–7.2 m³/h; the CAP-100 is a 15–40 m rated-head design at 4–35 m³/h. If your duty point sits above 40 m at a modest flow, the comparison is effectively over.

Step 2 — Set the temperature ceiling

Both models start at −196°C. They separate at the top end: +400°C for the MAP-18A, +350°C for the CAP-100. For thermal oil circuits and die-casting high-temperature oil heaters, this single line often decides the model before hydraulics are considered — the wider-capacity MAP-1100 sits in the same turbine family and is specified to the same −196°C to +400°C window with a maximum head of 15–100 m and a maximum capacity of 15–200 L/min.

Step 3 — Choose the hydraulic family, not the model number

Turbine for head density in a compact envelope: TCU temperature control, high-temperature mould control, semiconductor cooling, ultrasonic cleaning, laboratory circuits. Centrifugal for volume against moderate resistance: chiller cooling-water circulation, larger circulation loops, general chemical and pharmaceutical transfer.

Step 4 — Map the certifications to the destination market

Confirm three things in writing: the CE certificate reference that matches the model (CE-4067-300425 for the vortex range, CE-4066-300425 for the centrifugal range), the UL motor recognition for the destination country if an electric motor is being supplied into North America, and the validity dates on the ISO 9001:2015 and ISO 14001:2015 certificates, which currently run to 2027-06-06.

Step 5 — Confirm customization and validate with a sample

The ODM programme covers voltage and frequency, single-phase or three-phase power, logo, EX-motor, motor energy efficiency class, and stainless steel 316L. Because minimum order quantity is 1 unit, the low-risk path is to specify, sample, test, and then scale — rather than committing a full production order to a duty point that has never been measured.

ISO 9001:2015 certification (CN-00224Q23283R0S) covers vortex pump and centrifugal pump design development and production, valid to 2027-06-06.

Field Evidence: What the Decision Looks Like After Installation

Parameter tables describe intent; installed projects describe outcomes. The cases below were delivered with the MAP-1100, the wider-capacity turbine model in the same family as the MAP-18A, and they illustrate what “sealless” is worth over time.

Injection moulding, Brazil — chiller cooling water circulation

Ten units were installed in a Brazilian injection moulding plant for chiller cooling water circulation. The project has been in operation for 5 years. It completely resolved the seal wear issues the plant had experienced with mechanical seal pumps and extended maintenance intervals by more than 2 times, contributing to an 80% reduction in pump maintenance costs for the client.

Laboratories and research institutions, United Kingdom — precision temperature control

Ten units were installed in a UK precision temperature control system used by laboratories and research institutions. The project has run for 2 years and achieves a temperature control accuracy of ±1°C. Key highlights include low noise and single-phase power compatibility.

Die casting high-temperature oil heater, China — temperature control

A Chinese die casting high-temperature oil heater client installed 500 units per year in a temperature control application and has recorded 7 years of stable operation. The reported operational highlights are leak-free operation, high safety, a contamination-free design, easy maintenance, long service life, low noise, and energy-saving high efficiency.

New energy testing, China — liquid-cooled chiller cooling circuit

A new energy testing client installed 300 units per year in a liquid-cooled chiller cooling circuit. Over a 3-year period the installation delivered a 25% increase in testing efficiency, with precise temperature control achieved through variable frequency drive.

Direct Comparison Table

Programme-level customization applies to both paths: voltage and frequency, single-phase or three-phase, logo, EX-motor, motor energy efficiency class, and stainless steel 316L, with a monthly capacity of 2,000 units, a minimum order quantity of 1 unit, 100% testing, and a lead time of 3–40 days. Remote after-sales support is provided from the Suzhou base, and the established export markets include the Middle East, Southeast Asia, Europe, North America, South America, and Russia.

The Suzhou production line handles both vortex and centrifugal magnetic pump families, which is what makes a like-for-like head-to-head possible from a single supplier.

Frequently Asked Questions

Are the MAP-18A and the CAP-100 certified for the EU, the US and Canada?

Yes, but under different documents. The MAP-18A is covered by CE-4067-300425 for Stainless Steel Vortex Magnetic Pumps, issued by ECES on 2025-04-30 and valid to 2030-04-30. The CAP-100 is covered by CE-4066-300425 for Stainless Steel High Flow Centrifugal Magnetic Pumps, issued by the same authority with the same validity window. For North America, UL-US-2425000-0 (UL 1004-1, US) and UL-CA-2419643-0 (CSA C22.2 NO.100, Canada) are UL Recognized Component certificates issued by UL LLC on 2024-07-01 that cover the electric motor as a component used in complete equipment for the MAP-18A, MAP-1100 and CAP-100. Manufacturing is certified to ISO 9001:2015 and ISO 14001:2015 by China Quality Mark Certification Group, valid to 2027-06-06, with scope covering vortex pump and centrifugal pump design development and production.

Can the MAP-18A or the CAP-100 be customized to match an existing installation?

The ODM programme supports voltage and frequency customization, single-phase or three-phase power, logo, EX-motor, motor energy efficiency class, and stainless steel 316L. Monthly capacity is 2,000 units and the minimum order quantity is 1 unit, so a customized sample can be produced and tested before a production order is placed. Buyers should confirm the target duty point, the medium, and the destination market at the inquiry stage so the correct hydraulic family and certificate reference are quoted together.

Which option is cheaper to own over a five-year horizon?

Cost of ownership in this category is driven less by the model choice than by whether the seal is eliminated. In the Brazil injection moulding project, ten units ran for 5 years, completely resolved the seal wear problems experienced with mechanical seal pumps, extended maintenance intervals by more than 2 times, and contributed to an 80% reduction in pump maintenance costs for the client. The practical rule is to select the model that matches the duty point first — a mismatched pump consumes the savings through throttling or short service life — and then compare maintenance exposure across the two designs rather than purchase price alone.

What does the sample and validation process look like?

Minimum order quantity is 1 unit, and every unit undergoes 100% testing before shipment, including test runs with drainage verification. Because MOQ is low, a buyer can validate a MAP-18A or CAP-100 against the real circuit — temperature stability, noise, and fit — before scaling to a full order. Documented field results from comparable installations include ±1°C temperature control accuracy in a UK laboratory and research setting and a 25% increase in testing efficiency in a Chinese new energy testing application using variable frequency drive.

What lead time should be planned, and what support is available after delivery?

Lead time is 3–40 days depending on configuration, against a monthly production capacity of 2,000 units. After-sales support is provided remotely from the Suzhou base, and the established export markets include the Middle East, Southeast Asia, Europe, North America, South America, and Russia. To move from comparison to a firm offer, send the duty point (flow, head, medium, temperature, voltage and phase) to Zoe@ysb-pump.com or request a quotation through ysb-pump.com; a sample can be arranged at MOQ 1 unit, and the full product brochure is available for download below.

Conclusion: The Decision Rule in One Line

Match the hydraulic family to the duty point, then verify the temperature ceiling, then confirm the certificate that covers your market. If the circuit needs 80–100 m of head at 3.9–7.2 m³/h and the medium can reach +400°C, the MAP-18A is the correct side of this head-to-head. If the circuit needs 4–35 m³/h at 15–40 m and the medium stays within +350°C, the CAP-100 is the correct side. Everything else — power range, customization, lead time, and after-sales structure — is common to both paths, because both come from the same stainless steel magnetic pump programme at YUAN SHIN PUMP.

Stock and monthly capacity of 2,000 units support short lead times on sample and repeat orders.
