Built to take the pressure: the CRNE-HS and CRN-SF

The single-pump CRNE-HS and two-pump CRN-SF solutions are in-line, multi-stage pump systems designed to withstand the extreme conditions of high-pressure applications and built from AISI 316 grade stainless steel. They are perfect for washing systems, water treatment systems, industrial plants, boiler feeding systems, filtration and reverse osmosis.

High pressure applications often expose pumps to a variety of extreme conditions, such as high inlet pressure, high operating pressure, frequent start/stops and pressure pulsing. Overload of the pump may cause increased wear of pump parts, such as motor bearings and shaft seal, and thereby reduce pump life. Use the single-pump CRNE-HS for flow rates up to 5 m3/h, and the 2-pump CRN-SF models for flow rates above this.

Hard work, tough pumps 

Eliminate pressure stress from the sensitive shaft seal and provide pressures up to 50 bar at maximum 120 °C. 

The perfect pump solution

Reliable, highly efficient, space-saving design. 

World-class efficiency

The CRNE 1-HS and CRNE 3-HS pumps are available with the high-efficiency IE5 MGE motor with integrated variable-speed drive. 

Capable and tough
