1HP Oil transfer pump with 43psi pressure relief. Perfect for hose reel applications where flow will go to zero before the pump can be turned off (pump must still be turned off as soon as possible to prevent overheating) Powerful 1HP Oil Transfer Pump Heavy Duty gear pump with a massive Baldor Motor.
Twin rotary gears are set in the pump body. One is active, the other is passive. Active gear drives passive gear to rotate when pump works. As gear teeth unite then sever, vacuum/suction is created in pre-chamber. Liquid fills the gear cavities and is pushed at high pressure out from the chamber.
Safety valve is set from factory. Safety valve is automatically opened when pump or output piping receive excess pressure. Once valve opens, pressure and oil is routed back to the inlet chamber and re-circulated through the pumphead.
Not for use with corrosive liquids. Oil Only!
