OPERATION
WHAT IS “HEAD”?
Head refers to the height of a column of water that can be delivered by the discharge of the pump.

Suction head is the vertical distance between the centre of the pump and the surface of the liquid on the suction
side of the pump. May also be referred to as “suction lift”. The atmospheric pressure of 14.7 PSI at sea level limits
suction head lift to less than approximately 26 feet for any pump.
Discharge head is the vertical distance between the pump’s discharge port and the point of discharge, which is the
liquid surface if the hose is submerged or pumping into the bottom of a tank.
Total head is the sum of the suction head value plus the discharge head value.
As water pumping height increases, pump output decreases. The length, type, and size of the suction and
discharge hoses can also significantly affect pump output.
It is important for the suction operation to be the shorter part of the total pumping action. This will decrease the
priming time and improve pump performance by increasing the discharge head.
Suction lift is a maximum 26 feet and total dynamic head cannot be more than 197 feet.
NOTE:
Move the water pump to a safe operating location. For the best pump performance, locate the pump on a
flat, level surface as close as possible to the water to be pumped. Secure the water pump to avoid tipping over.
Use hoses that are no longer than necessary.
CAUTION! Direct the open end of the discharge hose away from homes, electrical devices or anything not
desired to get wet.
WARNING! Fuel and its vapours are extremely flammable and explosive. Fire or explosion can cause severe
burns or death.
1. This water pump is not for use in mobile equipment or marine applications.
2. Do not tip the engine or equipment at an angle that causes fuel to spill.
3. Secure the water pump. Loads from hoses may cause the unit to tip over.
