Overview:
Heavy-Duty Pressure Transfer Pump
Moderate pressure, high delivery, double acting, heavy-duty pumps for transfer of grease up to NLGI-2. Recommended to use with low consistency grease in centralized grease systems that do not require a high pressure outlet, and in large distribution systems of high viscosity oils.
Pump are available with tube length to fit commercial 400 lb drums. They can be flange cover mounted to 400 lb open drums.
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
Low friction polyurethane seals, hard chromed steel fluid plunger and steel valves for fewer repairs
Cast iron pump body
To stand higher working pressures
Double acting pump
Double ball valve design provides even and smooth fluid flow
