Materials:
A - CPVC
Penguin Pumps are designed to handle a large range of chemicals without difculty. Completely
constructed of CPVC where in contact with the solution being pumped, Series PX pumps have an
upper working temperature of 180 degrees and thus can handle slurries, and most corrosive and
abrasive solutions. Series PX pumps are easy to install and operate, and are virtually mainte-
nance-free. All pumps have been tested for proper operation before leaving the factory. To obtain
optimum service life, please follow all installation and operating instructions.

All models are supplied with three phase dual voltage, 208-230/460V,
50/60c motors, which are not wired at the factory. When changing from
230V wiring to 460V wiring, follow the motor manufacturer’s wiring
instructions, which can generally be found either on or in the motor
junction box. Check rotation of external fan by removing splash shield,
fan spins clockwise. It is imperative that the motor rotation be checked
before operation. Attach leads to motor and bump start for a maximum
of a couple of seconds as if you were turning a light switch on/off as fast
as possible. Do not leave motor running. As viewed from the suction
entrance of the pump, check for counterclockwise rotation. If clockwise
rotation, change any two hot leads and again check rotation. Replace
fan splash shield. Many options are available on the PX Series motors
including explosion-proof, larger horsepowers to 15, and 575V motors.
If any of these options are required, please check the motors carefully
or consult the factory.
The suction side piping of the pump is extremely important.
Mistakes can usually be compensated for if made on the discharge
piping. However, piping problems on the suction side can be, and
usually are, the source of ongoing problems. If a suction line
or suction extension is required, enlarge the suction line/exten-
sion 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. The suction piping needs to be arranged in
such a way as to allow a straight, even ow of liquid into the eye
of the impeller. This requires that all elbows, valves, or strainers
be located at a straight and uninterrupted distance equal to at
least 5-10 times the pipe diameter. Remember, elbows create
turbulence and air entrapment. 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 either ooded suction or non-ooded suction conditions the use
of a check valve on the discharge of the pump is recommended. In
The correct liquid level is very important. A liquid level which is too high
could cause motor damage. A liquid level that is too low, below the wear
ring, may cause severe impeller damange, THIS PUMP CANNOT RUN
DRY. CHECK THE LIQUID LEVEL. The correct liquid level is halfway
between the bung hole and the centerline of the discharge nozzle.
Under ooded conditions, open all the valves in the suction and
discharge lines. Wait a few minutes to let entrapped air out. Throttle the
discharge valve 2/3 closed. Leave suction valves wide open. A closed
suction or discharge valve could cause damage to the impeller and the
shaft. Start the pump and open the valve to the desired ow. Under
non-ooded conditions, ll up the pump slowly from the T-connection
and valve. See recommended installation. Then throttle the discharge
valve 2/3 closed. Start the pump and continue as ooded conditions.
Installation & Operating Instructions
PLUMBING CONTINUATION
the case of a non-ooded suction, a apper check valve on the end of
the submerged suction line must be installed. To facilitate priming the
pump, install a T-connection with a small valve between the 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. Also a good rule of thumb is that the source solution
tank volume should be three times the ow rate of the pump.

RECOMMENDATIONS
Always make sure there is enough liquid in the reservoir and that the level is high enough, considering the capacity of the pump unit. Inad-
equate liquid will cause a vortex in the reservoir. A vortex occurs when air mixes from the surface into the uid, which can disturb the ow and
also can prevent the pump from priming. Therefore, a rule of thumb is to maintain a minimum of 2ft. of suction pipe submergence in order to
prevent the formation of vortices. Suction pipe velocities should not exceed 5ft/sec. In cases where the pump is installed outside the reservoir,
do not run against a closed discharge valve for more than 1 minute. This will cause overheating of the uid in the pump and will damage 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.

DISASSEMBLY
1. Unscrew and remove discharge piping. Remove the six (6) snap ring screws. Now the snap ring can be removed using a screwdriver or a pair of
pliers.
2. With a rubber mallet, gently hit the back of the suction casing, alternating blows from one side to the other until the suction casing comes off.
Suction casing O-ring can easily be replaced.
3. Unscrew the impeller nut using a 3/4 inch socket wrench in a counterclockwise rotation. Impeller nut O-ring can be replaced.
4. Thread a 3/4-10UNC bolt into the hole in the center of the impeller eye. Holding the impeller, using an appropriate wrench turn the bolt clockwise
until the impeller slips off the shaft.
ASSEMBLY
1. Unscrew the fan cover screws and remove the fan, fan cover, and drip shield assembly.In order for the motor to stand on end, the fan shaft must
be placed in a hole deep enough for it to sit at on the end bell. With the motor in a vertical position, shaft upwards, place the four motor spacers
over the motor bolt holes. Place housing over shaft, lining up motor bolt holes in the mounting bracket with holes in the motor. Be sure the slinger
is properly in place. Screw the motor bolts into the holes beneath the mounting bracket in a diagonal sequence.
Be sure motor screws are tight.
2. Using loctite or other type of threadlocker, secure key into keyway on shaft. Insert the impeller into the housing. Rotate to engage key and slide
or lightly tap into place until it bottoms out. Do not hammer the impeller and sleeve down on the shaft. Screw the impeller nut clockwise holding
impeller. Be sure impeller nut O-ring is properly in place. After handtight, turn with wrench 180 degrees (10-15 inch lbs).
DO NOT OVERTIGHTEN.
4. Place the pump upright resting on the motor. Look down into the housing and, while rotating the impeller, check to see that the impeller is cen-
tered. The impeller must not be touching the side of the housing.
5. Lubricate support casing and casing O-ring. Be sure casing O-ring is properly in place. Slide suction casing over support casing, lining up timing
marks to assure proper t. Using a soft mallet, tap suction casing down onto support casing until snap ring groove is exposed. Line up through
holes in snap ring with the threaded holes in the support casing by rotating the snap ring clockwise. Insert and tighten the six (6) snap ring
screws.
