Graco Twin Post Ram Pumps for Sealants and Grease type Materials

Pumping very viscous materials

Very viscous materials such as sealants and some adhesives will not readily flow into the pump inlet. Our bare pumps overcome this by using a piston with a priming plate that pulls the material into the inlet.

Graco ‘Checkmate’ extrusion pumps

These pumps are specially designed for viscous materials and produce smooth flows over a wide viscosity range. The combination of priming piston, large internal ports and ‘severe duty’ construction results in a high quality pump for the most difficult of extrusion applications.

A large range of pumps

Beginning with the 10-1 ratio Monark pump, sizes and optional ratios progress through the President, Senator, Bulldog, King up to our biggest pump, the 82-1 ratio Premier. There is often a choice between Carbon Steel or Stainless Steel constructions.


We can offer a selection of extrusion guns.
