Receiving inspection

Upon receiving the pump, it should

shortages. If damage has occurred,

le a claim immediately with the

company that delivered the pump. If

the manual is removed from the

packaging, do not lose or misplace.

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.

At any time exceeding six (6) months,

but no more than twenty four (24),

the equipment must be stored in a

controlled area, keeping it away from

contact with rain, dust, etc., and the

temperature is maintained between

43-104 °F. If there is a possibility of

high humidity (coastlines, etc.), the

entire unit must be sprayed with

antioxidant liquid.

 Installation

The pump should be as close as

possible to the liquid to be pumped,

with

minimum

couplings, adapters, etc., in order to

reduce friction on the suction side.

The suction and discharge piping

must be perfectly aligned in the

independently using support or

anchors, this to prevent excessive

load on the volute.

The anchors of the motor are to be

approximately 4", this to prevent

accumulated water from entering the

to determine the dimensions of the

A successful operation depends on

limits. The minimum suction pipe size

to use can be determined by

comparing the NPSH available at the

Usually, we recommend using a pipe

A strainer or sieve should be installed

in the suction to prevent the entry of

objects. The strainer must have a free

entry area at least three times the

pipe diameter. Usually a suction valve

is combined with a strainer Figure 1.
