Why Iwaki — Magnetic Drive Technology

Sealless by design. Engineered for the duty cycle of critical cooling.

Iwaki America sealless pumps are engineered for high-reliability fluid circulation — critical in the precision cooling environments where chiller integration tolerates no margin for leaks or downtime.

Sealless Design

Magnetic coupling eliminates the dynamic mechanical seal — the single most common failure point in centrifugal pumps.

  • No seal wear, no shaft penetration
  • Prevents leaks and unplanned downtime

  • Ultimate Fluid Compatibility

Internal Cooling Circuit

The pumped fluid continuously cools internal pump components during operation.

  • Reduces internal operating temperatures
  • Extends bearing life under continuous duty
  • Sustains performance across long cycles

Advanced Materials

Materials science matched to the chemistries and conditions of modern cooling loops.

  • Non-Metallic & Stainless Steel

  • Low cost polypropylene
  • Optional ETFE for aggressive chemistries
  • Compatible with glycol and refrigerant fluids

Up to 170 PSI & 400 GPM

Compact. Reliable. Built for chiller integration.

Iwaki pumps deliver high flows and pressures across a range of sealless pump series — from compact DC-powered models to large-scale process pumps — sized to meet the demands of data center chillers, battery cooling platforms, and high-density thermal management systems.

Cooling is critical. Reliability is non-negotiable.

Modern data centers, battery systems, and power electronics generate extreme heat loads. Fluid handling is at the core of system performance, and the difference between continuous operation and catastrophic downtime.

Thermal sensitivity

Small thermal fluctuations cascade directly into compute performance and battery cycle health.

Failure consequences

A single cooling failure can shut down systems, damage critical equipment, and erase millions in investment.

Precision required

Reliability, accuracy, and continuous fluid handling are baseline requirements — not features.

Applications

One platform. Every thermal challenge.

From rack-level cooling in hyperscale data centers to grid-scale flow batteries, Iwaki magnetic drive pumps deliver the precision fluid handling that mission-critical thermal systems require.
