CPA-M Horizontal Magnetic Drive Process Pump

ANSI/ASME B73.3 horizontal, single-stage, sealless (OH1)

The CPA-M is a single-stage, horizontal magnetic drive centrifugal pump designed for industries requiring high reliability and zero leakage operation. Built in full compliance with ANSI/ASME B73.3 standards, this pump is ideal for handling hazardous, toxic, and aggressive fluids safely. Its sealless design eliminates the need for mechanical seals, reducing maintenance costs and ensuring environmental safety.

Operation limits:

Capacity: up to 2,200 gpm (up to 500 m³/h)
Head: up to 900 ft (up to 270 m)
Maximum pressure: 275 psi @ 100°F (19 bar @ 38°C)
Temperature: -184 to 840 °F (-120 to 450 °C)
Applications: chemical & petrochemical, tank farms, liquid gas industry, refrigeration & heat technology, power plants, hydrogen production, mining & mineral extraction

Overview
