Installation & Operating Instructions
Self-Priming Centrifugal Pump
BASIC PUMP INSTRUCTIONS
INSPECTION: The pump assembly was tested and
inspected before shipment. Before installation, inspect
the pump for damage which may have occurred during
shipment. Check the following: 1. Inspect for cracks,
damaged threads, and other obvious damage. 2.
Check and tighten loose bolts, nuts and other
attaching hardware. 3. Carefully read all warning and
cautions in the manual and on tags and labels on the
pump. 4. Note the direction of rotation indicated on the
pump. Check that the pump shaft rotates
counterclockwise facing the pump suction. CAUTION:
Only operate this pump in the direction indicated by
the arrow on the bearing pedestal. Otherwise, the
impeller could become loosened from the shaft and
seriously damage the pump.
PLACING PUMP: Locate the pump as close to the
liquid to be pumped as practical, but never higher than
25 feet. Level mounting is essential for proper
operation. The pump may have to be supported to
provide level operation and to eliminate vibration.
SUCTION AND DISCHARGE PIPING: Either pipe or
hose may be used for suction and discharge lines. If
hose is used in suction lines, it must be the rigid-wall,
reinforced type to prevent collapse under suction.
Using pipe couplings in the suction lines is not
recommended. Keep suction and discharge lines as
straight as possible and make minimum use of elbows
and fittings to minimize friction losses.
FIGURE 1 illustrates a typical installation. A bypass
line may be required for priming on high discharge
head applications.
CONNECTIONS TO PUMP: Before tightening a
connection pipe, align it exactly with the pump port.
Never pull a pipe line into place by tightening the
flange bolts and/or couplings. Lines near the pump
must be independently supported to avoid strain on
the pump. If hoses are used, they should have
adequate support to secure them when filled with
liquid.
SUCTION LINES: The suction line must be as short
and direct as possible and the line must always slope
upward to the pump from the source of the liquid. The
suction line should not exceed 30 feet in length.
Suction lines should be the same size as the pump
inlet. Use pipe sealant on the threads of the fittings.
STRAINERS: A strainer is furnished with the pump,
be certain to use it. It is provided with openings small
enough to prevent big stones, etc. from damaging the
impeller. Keep strainer clean. If possible, suspend it to
keep it from working into sediment.
VALVES: A check valve in the discharge line is
normally recommended, but it is not necessary in low
discharge head applications. If a throttling valve is
desired in the discharge line, use a valve as large as
the largest pipe to minimize friction losses. With high
discharge heads, it is recommended that a throttling
valve and a check valve be installed in the discharge
line to protect the pump from excessive shock
pressure and reverse rotation when it is stopped.
BYPASS LINES: If it is necessary to permit the
escape of air to atmosphere during initial priming or in
the repriming cycle, install a bypass line between the
pump and the discharge check valve. The bypass line
should be sized so that it does not affect pump
discharge capacity.
ALIGNMENT: The alignment of the pump and its
power source is critical for trouble-free mechanical
operation. The driver and pump must be mounted on a
common base so that their shafts are aligned with and
parallel to each other. It is imperative that alignment
be checked after the pump and piping are installed,
and before operation. WARNING: When checking
alignment, disconnect the power source to ensure that
the pump will remain inoperative.
COUPLED DRIVES: When using couplings, the axis
of the power source must be aligned to the axis of the
pump shaft in both the horizontal and vertical planes.
Most couplings require a specific gap or clearance
between the driving and the driven shafts. Refer to the
coupling manufacturer’s service literature. The
coupling is in alignment when the hub ends are the
same distance apart at all points. (See Figure 2)
