Pump Placement - Husqvarna W 100D Operator's Manual

OPERATION

PUMP PLACEMENT

For best pump performance, place the pump on a firm, level surface,
and near the water level, and use hoses that are no longer than
necessary. That will enable the pump to produce the greatest output
with the least self-priming time.
As lift (pumping height) increases, pump output decreases. The length,
type, and size of the suction and discharge hoses can also significantly
affect pump output.
Discharge lift capability is always greater than suction lift capability, so it
is important for suction lift to be the shorter part of total lift. The
maximum available suction lift will vary based on the operating
conditions. However, the suction lift can never exceed 25 feet
(7.5 meters) and should always be kept as low as possible.
Minimizing suction lift (placing the pump near the water level) is also
very important for reducing self-priming time. Self-priming time is the
time it takes the pump to bring water the distance of the suction lift
during initial operation.
