Low-Pressure Pump Model 7880-C1
Description
The major components of low-pressure pump model 7880-C1
consist of a reciprocating differential air motor and a double-acting
pump tube.
The pump is designed to deliver a mixture of antifreeze and
water. It can also be used to dispense windshield washer fluid and
water.
This low-pressure (2-1/2:1 ratio) pump includes a 2 " NPTF (m)
thread for mounting on the 2 ’’ bung thread of a drum or tank. With
the use of an extension (not included) the pump can accommodate
different size drums and tanks.
The pump can also mount to a wall (with the use of a wall
bracket) and be used with an optional siphon wand kit. See Table 4
for details.
