PIPING

Always install a section of straight pipe between the suction

side of the pump and first elbow or install an AC Fire

Pump Systems Suction Diffuser. This reduces turbulence of

the suction by straightening out the flow of liquid before it

enters the pump. The length should be equal to five times the

diameter of the pipe.

Be sure to eliminate any pipe-strain on the pump. Support the

suction and discharge pipes independently by use of pipe

hangers or ground supports close to the pump. A support can

be bolted to the underside of the pump body but it must be so

constructed as to allow freedom of movement with the normal

expansion of the piping.

If the pump is to be mounted in vertical piping with the motor

in the horizontal position provide adequate support to prevent

strain on pump parts and piping. It is not recommended that

pump be mounted with the motor vertically downward. Do not

use motor lift rings as a means of suspending the pump.

Line up the piping so that the bolt-holes in the pump flanges

match the bolt-holes in the pipe flanges. DO NOT ATTEMPT

TO SPRING THE SUCTION OR DISCHARGE LINES INTO

POSITION. Bearing wear will result if suction or discharge lines

are forced into position. The code for Pressure Piping

(A.S.A.B. 31.1) lists many types of supports available for vari-

ous applications.

ROTATION

Pump rotation is clockwise when viewed from back of the

motor. An arrow is provided to show direction of rotation.

GENERAL INSTRUCTIONS

1. Keep the motor properly lubricated.

2. When there is a danger of freezing, drain the pump.

3. Inspect pump regularly for leaky seals or gaskets and loose

or damaged components. Replace or repair as required.

As a rule, ordinary wire or band hangers are not adequate to

maintain alignment. It is very important to provide a strong,

rigid support for the suction and discharge lines.

Where considerable temperature changes are anticipated,

fittings for absorbing expansion should be installed in the

system in such a way as to avoid strain on the pump.

On an open system with suction-lift, use a foot-valve of equal

or greater area than the pump suction piping. Prevent clogging

by using a strainer at the suction inlet next to the foot-valve.

The strainer should have an area three times that of the

suction pipe with a mesh hole diameter of no less than

An A-C Fire Pump Systems Check Valve installed in the dis-

charge line will serve to protect the pump from water hammer,

as an isolation valve for servicing and for throttling.

NOTES:

1. The pipeline should have isolation valves around the pump

and have a drain valve in the suction pipe.

LUBRICATION

Your Series 1580 Inline Fire Pump has been lubricated at the

factory, future lubrication should be in accordance with the

motor manufacturers instructions.
