Johnson Combichem Centrifugal Pumps by Makharia Machineries Pvt. Ltd.

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.
