Gear pumps are characterised by being safe and easy to use. They can be used for a variety of tasks for pumping nearly all types of liquids with viscosity <200cSt and particles <10um.

They are virtually maintenance free, easy to service and leak free. 

The pump head housing and the internal metal parts are in AISI 316L stainless steel and the gears are available in PEEK™ or PTFE™.
