Overview:
Heavy-Duty High Flow/Pressure Pump
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.
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
