Introduction to the MC3 Diaphragm Pump

Description 

(Note: The MC3 has been discontinued as of Jan 1, 2024) 

The MC3 Chem-Feed® Diaphragm Pump is a positive displacement chemical metering pump that delivers reliable chemical feed.   

The MC3 diaphragm pump features a motor-driven diaphragm with full stroke length for consistent flow. 

The MC3 uses either DiaFlex^® or Flex-A-Prene^® diaphragms.  DiaFlex^® diaphragms are guaranteed to last the life of the pump.

Applications 

The MC3 pump is designed to provide smooth chemical feed for various chemicals and processes.  It can reliably pump aggressive acids, caustics, fertilizers, soaps, and a variety of other chemicals.  

The smooth flow profile and full diaphragm stroke allow the MC3 to minimize vapor lock and the need for re-priming.   

The MC3 pump is constructed of chemical-resistant materials, making it an excellent choice for aggressive acids and mixed or proprietary chemicals.
