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 ratio) pump

includes a 2 in NPTF (e) thread for mounting
on the 2 in 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
