Ventilation
Ventilation and drainage must be provided to prevent
damage to the motor from heat and moisture.
Freezing
The pump and all piping must be protected from freezing.
If freezing weather is forecast, drain pump or remove
completely from the system.
Water Supply
The water source must be able to supply enough water to
satisfy the capacity of the pump and water needs.
Suction Lift
Suction lift is the vertical distance from the lowest level
of the water to the pump intake. See performance charts
on page 2 and 3 to determine how far your pump can lift
water.
Horizontal Distance
The horizontal distance is the horizontal measurement
between the pump suction and the water source. This
distance may affect the ability of the pump to operate. If it
is over 100 feet, call the manufacturer for assistance at
1-800-742-5044.
Pipe And Fittings
Use galvanized steel or NSF PW Schedule 40 PVC pipe
and ttings. This material is designed for water pressure
and will seal against air and water under pressure. Do Not
Use: DWV ttings, as these are designed for drains without
pressure and will not seal properly. (Fig. 1, 2 & 3)

3/4 or 1 in.
When connecting a drive point (Fig. 2) a check valve must
be used in the suction line in place of a foot valve. For easy
priming connect the check valve as close to the well as
possible.
All piping from the well to the pump should slope slightly
upward with no sagging. Support suction pipe between
water source and pump. Unions in the suction line near
the pump and well will aid in servicing. Be sure to leave
enough room so that wrenches can be used easily.
Deep Well (Double Pipe System)
Where water level is greater than 25 feet and inside
diameter of well is four (4) inches or larger (Fig. 1).
1. Attach the foot valve to the ejector using a galvanized
steel or plastic nipple. Add enough 1 in. pressure pipe
and 1-1/4 in suction pipe to submerge ejector 10 to 15’
below pumping water level, making certain foot valve is
at least ve (5) feet from bottom of well. If pressure pipe
and suction pipe of the same diameter are used, be sure
to identify them clearly so that they will be connected to
the proper tappings of the pump.
If a known well leak exists, replace nipple with 21 feet
of 1” tail pipe between the ejector and the foot valve.
This will provide a continuous source of water for the
pumping system.
2. Check pipe and foot valve for leaks by lling pipes with
water. A continuous loss of water indicates a leak in the
piping, foot valve or unions, and must be corrected.
3. If no leaks are found, proceed to WELL TO PUMP
CONNECTION (SUCTION PIPE). For long offset
distances, see Table B for proper pipe size.
4. All piping from the well to the pump should slope slightly
upward with no sagging. Support suction pipe between
water source and pump. Unions in the suction line near
the pump and well will aid in servicing. Be sure to leave
enough room so that wrenches can be used easily.

1)
On single pipe deep well installations, clean, sound well
casing must be used to give a tight seal.
NOTE: This application requires a well adapter for the top
of the well.
NOTE: Pre-soak packer leathers for approximately two
hours before installation.
1. Attach foot valve directly to bottom of ejector assembly.
Ejector must be submerged 10 to 15 feet below
pumping water level and the foot valve must be at least
ve (5) feet from bottom of well.
2. Attach foot valve and packer ejector to suction pipe
(presoak packer leathers for approximately two (2)
hours). Push the assembly down the well. Some force
may be required to push the ejector down the casing.
3. As each section is lowered, check for leaks by pouring
water into the suction pipe.
4. Attach well adapter to suction pipe, lower over casing
top and tighten adapter ange.
5. If no leaks are found, proceed to WELL TO PUMP
CONNECTION (SUCTION PIPE) using piping of
the same diameter as the suction pipe (1-1/4”) and
pressure pipe (1”) tappings of the pump. For long offset
distances, see Table B for the proper pipe size.
6. Unions in suction and discharge piping near pump
and well will aid in servicing. Be sure to leave enough

PUMP PRIMING & STARTUP
Shallow Well Application Only:
CAUTION: All pumps must be primed (lling the
cavity with water) before they are rst operated. This
may take several gallons of water, as the suction line will
be lled in addition to the pump cavity.
1. Remove the 1/2 in. priming plug with pressure gauge
and air relief plug. (Fig. 1)
2. Slowly ll pump cavity until water comes out of air
relief hole on top of the pump.

3. Replace air relief plug and continue adding water to
pump cavity until water reaches the top of the priming
plug. (Fig. 3)
4. Thread in priming plug and then open optional ball
valve if installed by turning handle to line up with the
pipe. (Fig. 4)
5. Turn on breaker to start pump
IMPORTANT: If the pump hums instead
of pumping or turns off repeatedly, shut pump off
immediately.
Check voltage. Make sure your incoming voltage
matches the pump wiring voltage. See wiring guide in the
instructions.

PUMP PRIMING & STARTUP
Deep Well Application Only:
CAUTION: All pumps must be primed (lling the
cavity with water) before they are rst operated. This
may take several gallons of water, as the suction line will
be lled in addition to the pump cavity.
1. Remove the 1/2” priming plug. (Fig. 1)
2. Fill pump cavity with water until full and replace
priming plug. (Fig. 2)

3. Tighten ow control screw completely by turning
clockwise, then loosen two turns. Now start the pump.
(Fig. 3)
4. If pump is properly primed, pressure will quickly build
and register on the gauge mounted directly on the
pump body. If pressure does not build repeat priming
operation. All air must be vented from the drive and
suction pipes as well as the body before the pump will
prime. The pump body may need to be lled several
times in order to achieve the prime. (Fig. 4)

5. With pump operating at high pressure, open two or more
faucets and slowly unscrew the ow control screw until
maximum ow is obtained. This steady pressure will be
minimum operating pressure and should agree with the
pressure shown below. The ow control screw diverts
the proper amount of water to operate the ejector. (Fig.

The correct control valve setting will depend on the type of well installation and pressure switch setting for the particular
pump.
NOTE: Flow control is not required for shallow well applications.
IMPORTANT: If the pump fails to prime within ve minutes:
Turn power off at the breaker box. Look for leaks or a milky color in the discharged water, which indicates an air leak. Re-
prime if necessary, following steps 1 through 5 above. Reset breaker at the breaker box. All connections must be water
and air tight in order for pump to operate.
CARE AND MAINTENANCE
MAINTENANCE
Lubrication
The pumps and motors require no lubrication. The ball
bearings of the motor have been greased at the factory
and under normal operating conditions should require no
further greasing.
Freezing
1. Drain the entire system if there is danger of freezing.
A drain plug is provided at the bottom of the pump
case for this purpose. (Fig. 1)

CARE AND MAINTENANCE
Rotary Seal Assembly Replacement
CAUTION: Make certain that the power supply is
disconnected before attempting to service the unit!
The rotary seal assembly must be handled carefully
to avoid damaging the precision lapped faces of the
sealing components.
1. Disengage pump body from motor and mounting ring.
2. Remove diffuser and unthread impeller from the motor
shaft. The motor shaft can be held by using a 9/16”
open end wrench on the ats located in the middle of
the mounting ring.
3. The rotary seal will come loose at this time. Use a
screwdriver (or similar instrument) to pry the ceramic
seal and rubber gasket from the recess of the mounting
bracket.
CAUTION: Be careful not to damage the motor
shaft or recess surface.
4. Clean the recess and motor shaft thoroughly.
5. Install the new rotary seal assembly:
a. Insert the ceramic seal and the rubber gasket into
the recess.
NOTE: To help facilitate installation, apply one drop of
liquid soap solution to the outside diameter of the rubber
gasket. Make certain that the ceramic seal is kept clean
and free of dirt and/or oil.
Liquid Soap Solution: One drop of liquid soap combined
with one teaspoon of water.
b. Slip the remaining parts of the rotary seal assembly
onto the motor shaft.
NOTE: Apply a light coating of liquid soap solution to the
inside diameter of the rubber drive ring.
6. Replace the impeller and diffuser removed in Step 2.
7. Reassemble the pump body to the motor and mounting
bracket.
MOTOR REPLACEMENT
The motor can be replaced with any standard Nema 56J
jet pump motor (of proper HP for each pump) by referring
to the following instructions.
1. Follow steps as outlined under Rotary Seal
Replacement and Pump Disassembly.
2. Remove cap screws that connect the motor to the
mounting ring and pull motor away.
3. Replace motor with standard Nema 56J jet pump motor
by positioning motor against the mounting frame and
assembling with four (4) cap screws.
Because damage to the shaft seal can occur in
disassembly, a new seal will be necessary.
4. Follow steps 4, 5, 6 & 7 of Rotary Seal Assembly to
reassemble the remainder of the pump.
