COMBICHEM

Overview

CombiChem is SPX Johnson Pump’s solution for liquid transport in the chemical industry. It is one of the most outstanding pump types of the Combi-system. The Combi-system is a modular programme of single stage centrifugal pumps with a high degree of interchangeability of parts between the different pump constructions.

CombiChem represents a range of horizontal centrifugal pumps, designed to ISO 2858 / EN 22858 (DIN 24256), suitable for handling low viscosity, clean or slightly contaminated liquids.

The design of CombiChem complies entirely to ISO 5199. The CombiChem offers a great variety of possible shaft sealings, bearing constructions and also a wide range of different materials, such as stainless steel, bronze, nodular cast iron or cast iron.

A leak free version of the CombiChem is the CombiMag, a magnetic coupled centrifugal pump, especially developed for the chemical industry.
