Samson - 531411/531421/531431 - PumpMaster 45 40:1
High flow double acting pumps with high pressure delivery for use in lubrication systems that require a combination of high flow and pressure delivery.

70:1 pressure ratio pumps are for use in applications requiring extra pressure output due to cold temperatures or when low air pressure could limit pump performance.

Both pumps can be used with grease up to NLGI-2 viscosity. They are available for cover mount to 120 lb and 400 lb open drums and for horizontal and side mount on grease totes, bags and tanks.

  • 4 1/2" air motor - Mechanically actuated air valve with only three moving parts and no springs. Large effective area for maximum pumping power
  • Efficient air exhaust - No ice forming, no stalling pump operation
  • Long life packings - Dual packing seals provides longer trouble free operation
  • High quality materials - Hard chromed steel fluid plunger and steel valves and cast iron pump body for fewer repairs
  • Cast iron pump body - To stand higher working pressures
