Heavy-DutyPumpMaster 45 70:1
SAMOA PumpMaster® 45 – 70:1 Ratio Grease Pumps
Heavy-Duty High Pressure Pumps
High pressure double acting pump for use in applications that require extra pressure output or when cold temperatures a low air pressure could limit pump performance. Pumps can be used with grease up to NLGI-2 viscosity. These pumps can be used in large distribution systems that include simultaneous operation outlets.
Pumps are available for cover mount to 50 kg – 120 lb and 185 kg – 400 lb open drum and for horizontal and side mount on grease totes and bags.
