TM 10-4320-348-14
WARNING
The pump unit must be connected to a suitable ground before operation. Arcing caused by
buildup of static electricity may ignite volatile fluids and cause explosion and fire.
CAUTION
Maintain clearance under the pump unit. Intake cooling air entering the underside of the pumping
unit can be blocked, causing damage to the unit.
NOTE
The pump unit is designed to be versatile and fulfill many potential tasks during the transfer of
flammable liquids. Therefore the following set up is a typical set up for transfer of flammable
liquid from a 55-gallon drum to a nozzle assembly at the dispensing point. The proper pump
accessories are provided with the pump unit to allow many other potential applications. For any
application, the basic setup remains the same for the pump assembly. The only differences would
be the pumping assembly accessories selected for use and connecting to the pumping assembly.
b.
Assembly of Pumping Assembly. (Refer to Figure 2-4.)
(1)
The pump unit should be positioned on a level surface near the source of fuel being pumped.
(2)
Drive ground rod (1) into earth. Secure one end of grounding cable (2) to pump ground connection (3).
Secure other end of grounding cable to ground rod (1). Make sure grounding cable makes metal-to- metal
contact with pump frame and rod.
(3)
Remove dust plug (4) from suction (intake) female cam-lock coupling (5). Remove dust cap (6) from
suction hose assembly (7). Connect male end of suction hose assembly (7) to suction (intake) female cam-
lock coupling (5).
(4)
Remove dust plug (6) from suction hose assembly and remove dust cap (9) from coupler and drum
unloader 90 degree elbow (10). Connect female end of suction hose assembly (7) to drum unloader 90
degree elbow (10) or make connections to other pump accessories as required by desired application.
(5)
Remove dust cap (11) from pump discharge male cam-lock coupling (12). Close the pump drain valve (13),
then prime the pump assembly by pouring approximately two gallons of the liquid to be pumped through the
pump discharge male cam-lock coupling (12).
(6)
Remove dust plug (14) from discharge hose assembly (15), and connect female end of discharge hose
assembly (15) to pump discharge male cam-lock coupling (12).
NOTE
As fluid fills the volute, air is removed through the discharge port.
(7)
Remove dust cap (16) from discharge hose assembly adapter and remove plug (17) from the nozzle
assembly coupler (18). Connect male end of discharge hose assembly (15) to nozzle assembly coupler (18)
or make connections to other pump accessories as required by desired application.
