Heavy Duty Air-Operated Grease Pumps

samoa

A full range of heavy-duty, high efficency, air powered piston pumps designed to pump today’s high viscosity greases at high flow rates.
• Time tested pneumatic air motor with only three moving parts and no springs for minimum maintenance.
• Aluminum air motor provides good heat transfer and incorporates high thermal efficiency, large diameter air exhaust manifolds.
• Muffler element design reduces noise levels.

SAMOA PumpMaster 45 – 40:1 ratio grease pump – 185 kg (400 lb) drum

531410

High flow double acting pumps with high pressure delivery for use in lubrication systems that require a combination of high flow and pressure delivery. Pumps can be used with grease up to NLGI-2 viscosity.
These pumps can be used in medium length systems that include simultaneous operation outlets.
Pumps are available for cover mount to 50 kg – 120 lb and 185 kg – 400 lb open drums and for horizontal and side mount on grease totes and bags.

FLUIDS HANDLED:

  • Grease up to NLGI-2.

MARKETS SERVED:

  • Heavy Duty service shops.
  • Fleets.
  • Mining and construction.
