INLET LINE
The suction line should be short and follow a direct
route with a minimum number of elbows and fittings.
Elbows should be located as far as possible from the
suction inlet to prevent head loss due to increased fric-
tion. Excessive friction losses in the suction line could
result in pump caviation, causing poor performance,
noise, vibration, damage to equipment and possible
damage to pruduct. Whenever practical the diameter of
the line at the suction inlet should be increased in size.
An eccentric tapered reducer should be used in lieu of a
concentric tapered reducer to prevent air pockets from
forming and impairing pump efficiency. In turn, the ec-
centric reducer may be placed at the inlet of the pump
and should be positioned so the straight side is up.
A horizontal suction line must have a gradual rise to the
pump. A high point in the suction line will form an air
pocket and prevent proper pump operaton. All joints in
the suction line should be air tight, to prevent air leak-
age which can reduce pump capacity and efficency.

OUTLET LINE
Position of the pump outlet line is preferably either
vertical or top horizontal. The discharge line should
be short and direct with a minimum number of
elbows and fittings. Elbows should not be used at the
discharge outlet as the friction encountered would
be increased, resulting in head loss. It is advisable to
increase the line diameter at the discharge outlet to
prevent head loss. However, use of a larger discharge
line than recommended may reduce the total pump
head, but increase the pump volume, which can
cause pump vibration due to overload. Use of a dis-
charge pipe smaller than the pump discharge outlet
increases the total pump head but decreases the
volume. If a reducer is required on the outlet port of
the pump and the discharge is vertical a concentric
reducer should be used. If the discharge is horizontal
an eccentric reducer should be used and should be
positioned so the straight side is down.
