Quick-Dispensing Drum Pumps with Nozzle for Fuel

These pumps have a _3/4" ID discharge hose for transfer applications and a vacuum breaker that drains the hose to prevent siphoning. A lever handle delivers fluid on both the forward and backward strokes for faster dispensing than other drum pumps. The handle can be mounted with the knob above or below the pump body. Lock the handle with a padlock (not included).

Pump Repair Kits—Repair kits include a gasket, a piston ring, O-rings, and valves.
