The pump performance is adversely affected by increased
suction lift. Place the pump as close as possible to liquid
being pumped. Always place pump on level ground to
insure sufficient engine lubrication and fuel supply. If
trailer-mounted, pump block wheels before operation. The
lines near the pump must be properly supported. Never
use shut-off valves.
SUCTion line
Use appropriate 6-inch diameter hoses, the suction hose
must be rigid, reinforced to prevent collapse under suction.
To prevent air pockets, the suction hose must be straight
short as possible; the line must always slope upward from
the water source to the pump. The line should not slope
down or air pockets may occur. If liquid being supplied to
pump is under pressure, the incoming pressure must be
limited to 50% of the maximum operating pressure based
on the pump engineering data curve.
diSCHaRged line
Maintain discharge lines straight as possible to prevent
whipping and reduce friction loss. The line friction can be
reduced with minimal use of fittings and elbows. If using
elbows, wide radius is preferred. Always use strainer
furnished with the pump.
FiTTingS
Use properly rated 6-inch size fittings. Align fittings to pump
before tightening connections. The pump connections
should be sealed with pipe sealant to ensure air tight seal. A
slight leak will affect priming ability and output performance
