Heavy-DutyPumpMaster 45 25:1
SAMOA PumpMaster® 45 – 25:1 Ratio Grease Pump – Heavy-Duty Pressure Transfer Pump
Moderate pressure, high delivery double acting pumps for transfer of grease up to NLGI-2. Also recommended for use with low viscosity grease in centralized grease systems that do not require a very high pressure output and in large distribution systems of high viscosity oils. Pumps are available with tube length to fit commercial 185 kg – 400 lb drums and they are available for cover mount to 185 kg – 400 lb open drums using a drum cover 418 017.
