Air Operated Extrusion Pumps for Transferring High Viscosity Grease, Pastes, Adhesives & Sealants

Heavy duty pressure primer ram pumps for extrusion of high viscosity materials such as grease, pastes and sealants from 20L pails up to 200L lidded drums. Featuring an air driven positive displacement piston pump equipped with a pressure plate that allows the user to pump dense and hard to pump products, with either a ball valve pump inlet or chop-check pump inlet (depending on material characteristics).

Chop-check pumps are used to pump the highest viscosity materials that are hardly capable of flowing at all, they feature a primer plate piston that cuts through stringy pasty materials to feed the reciprocating piston inside the pump. And for the hardest to pump materials we can also use a heated pressure plates, thermostatic heater jacket for the drums as well as heated hose's.

Extrusion Pumps are mounted directly onto and through the pressure plate, this forces the high viscosity material into the pump to prevent cavitation (channelling), eliminates trapped air and contamination and reduces material waste using large seals on the pressure plate the ram pushes the pump into the drum as it empties, scrapping the walls of the drum clean.

With our high viscosity piston pump packages we can also offer options such as drum empty alarms, pumping management systems, two-hand safety switches, drum loader rollers, grease dispensing valves, flow regulators and more.

  • Maximum production and operation capacity.
  • High power air motors.
  • Reduced maintenance.
  • A minimal amount of material left in the drum.
  • Drum empty alarm, level sensor.
  • Quick drum replacement.
  • Long working life-time.
  • Large range of hand held dispensers.
  • Small area footprint.
  • Electronic controls with custom configuration (on request).
  • Can be equipped heating systems to lower viscosity.
  • Management system for multiple pumps.
Examples of 30, 60 and 200 Litre pressure primers.
Our Range of Chop-Check pumps unmounted from the pressure plates.
