Install the pump as close as possible to the reservoir from which the liquid is being pumped. More energy is necessary to prime
the liquid than to discharge the uid, make the suction as short as possible.
ELECTRICAL
Models P-1/15 and P-1/6 pumps are supplied only in a single
phase, single voltage, 115V or 230V, 50/60c motor. All other
models supplied with a single phase are dual voltage, 110/220V
or 115/230V motors. The factory wires all dual voltage motors for
the lower voltage (110/115V) unless otherwise requested. When
changing from 110/115V wiring to 220/230V wiring, follow the mo-
tor manufacturer’s wiring instructions, found in the motor junction
box. Be sure to wire the motor for counterclockwise rotation as
viewed from the suction entrance of the pump. A power cord and
plug are supplied for immediate plug-in operation on motors wired
for the lower voltage. These motors have already been wired at
the factory for proper rotation. A plug is not supplied on motors
wired 220/230V. Epoxied motor housings are not available on
either voltage motor of the P-1/15 or P-1/6 pumps. All other motor
housings are epoxied standard.
If a suction line or suction extension is required, enlarge the suc-
tion line/extension by one size larger than the suction entrance.
Never reduce plumbing on the suction. Avoid 90-degree elbows and
never use a 180-degree elbow. Make sure every suction coupling/
connection is airtight. The bottom of the suction extension should
always be at least 2 pipe diameters above the bottom of the tank.
In the use of a check valve on the discharge of the pump is recom-
mended. In the case of a non-ooded suction, a apper/diaphram
check valve on the end of the submerged suction line must be

The correct liquid level is very important. A liquid level which is too
high could cause motor damage.
LIQUID LEVEL
Under ooded conditions, open all the valves in the suction and
discharge lines. Wait a few minutes to let entrapped air out. Close
all valves on the discharge line. Leave suction valves wide open.
A closed suction valve could cause damage to the impeller and
the shaft. Start the pump against a throttled discharge valve to let
out any additional entrapped air. Then open valve to desired ow.
PRIMING
Always make sure there is enough liquid in the reservoir and the
level is high enough, considering the capacity of the pump unit.
Inadequate liquid will cause vortex in the reservoir. A vortex occurs
when air mixes from the surface into the uid, which can disturb
the ow and also prevents the pump from priming. In cases where
the pump is installed outside the reservoir. Do not run against a
closed discharge valve for more than 5 minutes.
RECOMMENDATIONS
An on/off switch is optional, cost on price list, on Models P-1/4
– P-1 single phase. Motors supplied in three phase are dual volt-
age, 230/460V, 50/60c, which are not wired at the factory. Since
direction of rotation cannot be determined without operating the
pump, the pump head and snap ring must be removed prior to
bump starting. It is imperative that the motor rotation be checked
before operation. Attach leads to motor and bump start. Do not
leave motor running. As viewed from the suction entrance of the
pump, check for counterclockwise rotation. If clockwise rotation,
change any two leads and again check rotation. Replace head and
snap ring as described in Assembly. Many options are available on
the P Series motors including single phase-50c, explosion-proof,
larger horsepowers to 7
1
/2, and 575V motors. If any of these options
are required, please check the motors carefully or consult factory.
installed. To facilitate priming the pump, install a T-connection with
a small valve between pump case and check valve. It is advisable
to use a discharge valve after the check valve. All plumbing and
accessories must be supported other than by the pump, in order
to prevent possible distortion of the pump case. The use of some
hose in the discharge plumbing close to the discharge nozzle
of the pump will absorb any movement of the solid plumbing if
vibrations exists.
CHECK THE LIQUID LEVEL. The correct liquid level is halfway
between the vent hole and the centerline of the discharge nozzle.
Under non-ooded conditions, ll up the pump slowly from the T-
connection and valve. Then close all valves in the discharge line.
Start the pump and continue as ooded conditions.
This will cause overheating of the uid in the pump and will dam-
age the CPVC parts. Temperature in this case will increase up to
220 degrees. If the pump is being run against a closed discharge
valve for a long duration of time, install a small bleed line back into
the reservoir before the discharge valve of the pump. If the line is
small, there is a minimum pressure loss. This prevents overheating
by recirculating the uid.
