Receiving inspection
Upon receiving the pump, it should
be inspected for damage or
shortages. If damage has occurred,
file a claim immediately with the
company that delivered the pump. If
the manual is removed from the
packaging, do not lose or misplace.
4
Storage
Any product that is stored for a
period longer than six (6) months
from the date of purchase should be
bench tested prior to installation. A
bench test consists of, checking the
impeller to assure it is free turning
and a run test to assure the motor
(and switch if provided) operate
properly. Do not pump out of liquid.
4
Location
Locate the unit as close as possible to
the liquid being pumped in order to
reduce friction losses in the suction
pipe. Suction and discharge piping
should be perfectly aligned with the
pump
flanges and supported
independently using pipe hangers or
floor mounted supports.
**Consult pipe friction table and
accessories in order to determine your
piping dimensions.

Suction
Recommended to use robust and
self-supported piping and inspect for
any leakage.
For a successful installation you need
to rely on the friction loss calculation
in the suction part taking into
consideration the acceptable limits.
The minimum suction pipe to be
used can be determine by comparing
the NPSH available in the suction
part versus the NPSH require by the
impeller, as illustrated in the
performance curve.
Generally, we recommend to use ½”
to 1” bigger diameter piping to what
the pump suction diameter is.
