Convertible Well Jet
Pump Water Systems
Description
Jet pumps are single stage domestic water pumps designed for pumping potable water in applications where the water is up to 100 feet (deep well pump). A pressure switch is a standard feature. A built-in control valve is available on deep well pumps. Deep well pumps can be mounted to either a pre-charged, conventional type or free standing pressure tank.
Unpacking
After unpacking the jet pump, carefully inspect for any damage that may have occurred during transit. Check for loose, missing or damaged parts.

General Safety
Information
CALIFORNIA PROPOSITION 65
This product contains chemicals,
including lead, known to the State of California to cause birth defects and other reproductive harm. Wash hands after handling.
GENERAL SAFETY
1.Read all manuals included with this product carefully. Be thoroughly familiar with the controls and the proper use of the equipment.
2. Know the pump application, limitations and potential hazards.
Always install a pressure relief valve
to match the system pressure rating and the maximum flow rate.
Do not use to pump flammable
or explosive fluids such as gasoline, fuel oil, kerosene, etc. Do not use in explosive atmospheres. Pump should only be used with liquids compatible with pump component materials.
Failure to follow this warning can result in personal injury and/or property damage.
Disconnect power and release all
pressure from the system before attempting to install, service, relocate or perform any maintenance. Lock the power disconnect in the open position. Tag the power disconnect to prevent unexpected application of power.
Install a screen around the inlet pipe
to prevent entrapment of swimmers.
3.Drain all liquids from the system before servicing.
4.Secure the discharge line before starting the pump. An unsecured discharge line will whip and possibly cause personal injury and/or property damage.
5.Check hoses for weak or worn condition before each use. Make certain all connections are secure.
6.Periodically inspect pump and system components. Perform routine maintenance as required (See Maintenance).
7.Personal Safety:
a.Wear safety glasses at all times when working with pumps.
b.Keep work area clean, uncluttered and properly lighted replace all unused tools and equipment.
c.Keep visitors at a safe distance from work area.
d.Make the workshop child proof: use padlocks, master switches and remove starter keys.
8.Do not pump chemicals or corrosive liquids. Pumping these liquids shortens the life of the pumps seals and moving parts and will void the warranty.
9.When installing pump, cover the well to prevent foreign matter from falling into well and contaminating the water and damaging internal mechanical pumping components.
10.Always test the water from the well for purity before use. Check with local health department for test procedure.
11.Complete pump and piping system MUST be protected against below freezing temperature. Freezing temperatures could cause severe damage and void the warranty.

General Safety
Information (Continued)
12.Do not run the pump dry or damage will occur and will void warranty.
This pump is designed for indoor
installation only. Failure to install indoors will significantly increase the risk of injury or death from electrical shock.
All wiring should be performed by a
licensed or certified electrician.
13.For maximum safety, the unit should be connected to a grounded circuit equipped with a ground fault interrupter device.
14.Before installing the pump, have the electrical outlet checked by a licensed or certified electrician to make sure the outlet is properly grounded.
15.Make sure the line voltage and frequency of electrical current supply agrees with the motor wiring.
16.Do not attempt repairs to the electric motor. All repairs to the motor must be completed at a licensed or certified electrical motor repair shop.
Do not touch an operating motor.
Modern motors are designed to operate at high temperatures.
17.Avoid kinking electrical cord and protect electrical cord from sharp objects, hot surfaces,
oil and chemicals. Replace or repair damaged or worn cords immediately.
18.Keep fingers and foreign objects away from ventilation and other openings. Do not insert any objects into the motor.
Risk of electric shock! Never
connect the green (or green and yellow wire) to a live terminal!
19.To reduce the risk of electrical shock, the pump should be plugged directly into a properly installed and grounded 3-prong grounding type receptacle, as shown in
Figure 1. The green (or green and yellow) conductor in the cord is the grounding wire. The motor must be securely and adequately grounded for protection against shock.
Grounded Pin

|
20.Where a 2-prong is encountered, replace the plug with a properly grounded 3-prong receptacle in accordance with the National Electrical Code, local codes and ordinances. To ensure a proper ground, the grounding means must be tested by a licensed or certified electrician.
21.Use only 3-wire extension cords that have a 3-prong, ground type plug, and 3-pole receptacles that accept the equipment plug.
22.Use wire of adequate size to minimize voltage drop at the motor.
Do not handle pump or pump motor with
wet hands, when standing on a wet or damp surface or when standing in
water. Fatal electrical shock could occur.
Pump motor is equipped with an
automatic resetting thermal protector and may restart unexpectedly. Protector tripping is an indication of motor overloading because of operating pump at low heads (low discharge restriction), excessively high or low voltage, inadequate wiring, incorrect motor connections or defective motor or pump.
Pre-Installation
WATER SUPPLIES
The water supplies illustrated in Figure 26 are possible sources for water. These water supplies can be divided into two categories:
SURFACE WATER
Water from a lake, stream, pond and cistern. This water is usually not fit for human consumption, but may be
suitable for washing, irrigation or other household uses.
GROUND WATER
Water found in the water bearing stratum at various levels beneath the earth. Of all the fresh water found on earth only 3 percent is found on the surface and 97 percent is underground.
TANKS - CONVENTIONAL STORAGE
The function of the tank is to store a quantity of water under pressure. When full, the tank contains approximately 2/3 water and 1/3 compressed air. The compressed air forces the water out
of the tank when a faucet is opened. An air volume control automatically replaces air lost or absorbed into the water. The usable water, or draw-down capacity, of the tank is approximately 1/6 of the tanks total volume when operated on a “20-40” pressure setting (Figure 2).

Tank |
Tank |
Figure 2 - Conventional and
Pre-charged Storage Tanks
TANKS - PRE-CHARGED STORAGE
A pre-charged storage tank has a flexible bladder or diaphragm that acts as a barrier between the compressed air and water. This barrier prevents the air from being absorbed into the water and allows the water to be acted on by compressed air at initially higher than atmospheric pressures (pre-charged). More usable water is provided than with a conventional type tank. Precharged tanks are specified in terms
of a conventional tank. For example, a 20 gallon pre-charged tank will have the same usable water or draw-down capacity as a 40 gallon conventional tank, but the tank is smaller in size (Figure 2).
PRESSURE SWITCH
The pressure switch provides for automatic operation. The pump starts when pressure drops to a cut-in setting. The pump stops when pressure reaches a cut-out setting.

Pre-Installation
(Continued)
PACKAGE SYSTEMS
There are four jet pump/tank assemblies sold as packages (Chart 1).
WELLS
A new well should be pumped clear of sand before installing the pump. Sand will damage the pumping parts and seal. The draw-down level of the well should not exceed the maximum rated depth for the pump. The capacity of the pump will be reduced and a loss of prime may occur.
Installation
LOCATION
Select a location as close to the water supply as possible.
Be sure to comply with any state or local codes regarding the placement of the pump. The equipment must be protected from the elements. A basement or heated pump house is a
good location. Make sure the pump has proper ventilation. The temperature surrounding the pump is not to exceed 100° F (40°C) or nuisance tripping of the motor overload may occur.
This pump is designed for indoor
installation only. Failure to install indoors will significantly increase the risk of injury or death from electrical shock.
PIPING
Piping may be copper, steel, rigid PVC plastic or flexible polyethylene plastic.
Flexible pipe is not recommended on
suction pipe (inlet pipe).
The pipe must be clean and free of rust or scale. Use a pipe joint compound on the male threads of the metal pipe. Teflon® tape should be used with
plastic threads. All connections must be air tight to insure normal operation.
Slope all inlet piping upwards towards the pump to prevent trapping air. Unions or hose couplings can be installed near pump to facilitate removal for servicing or storage. A rubber hose installed between the water system and the house piping will reduce the noise transmitted to the house.
Plastic pipe can be used on all installations except 2 in. deep well jet. The 2 in. deep well jet requires 1-1/4 in. galvanized steel pipe and special machined couplings (1-13/16 in. O. D.).
The galvanized steel pipe and the couplings restrict the flow of return water back to the jet unless the couplings are machined.
PIPE SIZES
Long horizontal pipe runs and an abundance of fittings and couplers decrease water pressure due to friction loss. See Chart 2 to determine the proper pipe size.
SHALLOW WELL INSTALLATION
A shallow well jet assembly can be used with the deep well pump when the pump is located 25 feet vertically of the water level. Shallow well installations have only one pipe between the pump and water supply (Figure 3).
DRILLED WELL (FIGURE 17)
1.Install a foot valve on the first section of pipe (Figure 3, Illustration A).
2.Lower the pipe into the well.
3.Add pipe until the foot valve is 5 feet below the lowest anticipated water level.
The foot valve should be at least 18
in. from the bottom of the well or sand or sediment could be drawn into the system.
4.After proper depth is reached, install a well seal or pitless adapter to support pipe and prevent surface. water and other contaminants from entering well.

Installation (Continued)
DRIVEN WELL
•Drive the point several feet below the water table.
NOTE: A packer type foot valve can be installed in the well (Figure 3, Illustration B). This type of foot valve allows the well to be filled with water
when priming and makes the inlet pipe much easier to test for leaks. Follow the manufacturer’s instructions when installing the packer type foot valve.
As an alternative, an in-line check valve can be used with a driven well (Figure 3, Illustration C). The pipe between the check valve and the water level will always be under a vacuum.
Leaking joints or couplings will allow air to leak into the pipe and cause abnormal pump operation. Make sure to use pipe joint compound on all male pipe threads.
DUG WELL, CISTERN, LAKE AND SPRING INSTALLATION (FIGURE 17)
•Install a foot valve on inlet pipe and lower into water.
The foot valve should be at least 18
in. from the bottom of the well or sand or sediment could be drawn into the system.
NOTE: When a lake is used as a water supply, make sure the inlet pipe is deep enough to be submerged at all times. Protect the pipe from damage from swimmers and boats.
Slope the horizontal piping upward toward the pump to prevent trapping air. The pipe must be removed during winter months or protected against freezing.
Protect the pipe from damage from swimmers and boats.
Install a screen around the inlet
pipe to prevent the entrapment of swimmers.

3.Lower the jet into the water below the lowest anticipated water level, but never closer than 18 in. from the bottom. Sand or debris may be drawn into the system if the jet is too close to the bottom.
4.Provide protection for the jet and pipes against damage from boats or swimmers if a lake is used for the water supply.
NOTE: Single pipe packer jets rely on the space between single pipe and inside of well casing for return water to operate jet. Two inch installations must use 1-1/4 in. galvanized steel pipe with special turned couplings (1-13/16 in. O.D.) to avoid restricting flow of return water back to jet.
1.Assemble the foot valve and packer to the jet body.
2.Lubricate the rubber cups with petroleum jelly.
3.Attach the first section of pipe and lower jet into well.
4.Add pipe until the jet is positioned 5 - 15 feet below the lowest anticipated water level. The jet should never be closer than 5 feet from the bottom of the well or sand and sediment may be drawn into the system.
5.With the jet in position, fill the pipes with water to make sure the rubber cups are sealed against inside of the well casing. It may be necessary to move the jet up and down to seat the cups.
6.Install the casing adapter and the horizontal pipes.

1.Remove prime plug.
2.Fill pump and piping completely full of water.
3.Replace the prime plug.
4.Open a faucet to vent the system.
5.Start the motor. Water will pump in a few minutes. If pump fails to prime in 5 minutes, stop motor and refill pump with water. Priming time is proportional to the amount of air in inlet pipe. Do not allow pump to get hot.
6.Let the system operate for several minutes to flush all pipes.
7.Close faucet and allow pump to build pressure in tank. When the pressure reaches the cut-out setting, the motor will stop.
The system is now in operation and will automatically cycle on demand.
PRIMING THE DEEP WELL PUMP
To prevent damage to the pump, do not
start motor until pump has been filled with water.
1.Remove prime plug.
2.Fill pump and piping completely full of water.
3.Replace the prime plug.
4.Close the control valve (Figure 12) and open a nearby faucet.
5.Start the motor. The pressure inside the pump body will build almost
immediately as the pump, jet and piping become completely filled with water.
6.Slowly open the control valve. Water will begin to flow. Continue to open the control valve until maximum flow is achieved. Opening the valve too far will cause the water to stop flowing.
7.Adjust the valve until there is a steady flow of water. The valve should be opened as much as possible without losing pressure.
8.Let the system operate for several minutes to flush all piping.
9.Close the faucets and allow the pump to build pressure in the tank. When the pressure reaches the cutout setting, the motor will stop.
The system is now in operation and will automatically cycle upon demand.
Maintenance
Disconnect power and release all
pressure from the system before attempting to install, service, relocate or perform any maintenance. Lock the power disconnect in the open position. Tag the power disconnect to prevent unexpected application of power.
Protect the pump from freezing during
winter conditions.
DRAINING THE PUMP
Drain openings are provided on all models. To drain the pump:
1.Remove drain plug and prime plug to vent the system.
2.Drain all piping to a point below the freeze line.
DRAINING THE TANK
Conventional tanks can be drained by opening an outlet at the lowest point in the system. Remove plug or the air volume control to vent the tank.
Pre-charged tanks force virtually all the water from the tank when system pressure is released. No draining is necessary.
RESTARTING PUMP
If the pump has been serviced, drained or has not been used for some time, be sure there is water in the pump housing (volute) and the piping to the well. There must be water in the pump housing (volute) at all times when
the pump is running to avoid internal damage of seal members (See Priming the Shallow Well or Priming the Deep Well Sections).
WATERLOGGED TANKS:
CONVENTIONAL
When a tank system has an inadequate ratio of air and water, the pump will start and stop often and erratically.
1.Disconnect the power to the pump.
2.Open the lowest faucet in the system to release all pressurized water in the system.
3.Prime the pump (See Priming the Shallow Well or Priming the Deep Well Sections).
4.Reconnect the power to the pump.
NOTE: As the pump refills the tank with water, the air volume control supplies the tank with the correct air to water ratio for the system to operate. If the air volume control is good, the pump will shut off at the desired cut-off and will be adjusted correctly.
WATERLOGGED TANKS: PRECHARGED
If a pre-charged tank becomes waterlogged, the bladder is normally leaking or broken.
1.Test the tank by depressing the air valve. The air valve will expel water if the bladder is broken.
2.Replace the tank.
NOTE: Once a bladder is leaking or broken, the bladder cannot be repaired. The tank must be replaced.

Maintenance (Continued)
PRE-CHARGED TANK
Some air is lost through the bladder in any tank. To prevent tank failure, check the tank pre-charge on a yearly basis.
1.Disconnect power to the pump
2.Open a faucet nearest the tank and allow all water to drain from the tank.
3.Measure the tank pre-charge at the valve stem using a tire gauge.
4.If necessary, adjust the pre-charge with an air pump 28 - 30 psi on 1/2, 3/4 and 1 HP pumps.
LUBRICATION
The bearing used in the pumps are lifetime lubricated at the factory and require no additional lubrication.
REMOVING OLD SHAFT SEAL
Turn disconnect switch to “off”
position.
1.Disconnect power to the pump
2.Open a faucet nearest the tank and allow all water to drain from the tank.
3.Remove the four cap screws holding the pump housing (volute) to the motor (Figure 13).

4.Separate the pump housing (volute) from the motor to expose the diffuser and the seal plate.
5.Remove the two cap screws and diffuser from the seal plate to expose the impeller.
6.Remove the small end cap on the end of the motor opposite the impeller.
7.With a large screwdriver or adjustable wrench, keep the shaft from rotating and remove the impeller with hand (standard right hand thread). Be sure to hold onto the cast iron seal plate when removing the impeller from the shaft.
8.Remove the seal plate.
9.Pry the rotating shaft seal member from the impeller (Figure 14).

10.Push or pry the ceramic seat free from the seal plate (Figure 14).
11.Remove loose particles from impeller hub and seal plate.
INSTALLING NEW SHAFT SEAL
Before handling shaft seal parts wipe
hands clean. Dirt or grease can damage the seal.
1.Wet the inside of the seal cavity on seal plate and the rubber cup enclosing the new ceramic seat with cooking oil. Be careful not to scratch the ceramic surface of the seal seat and push seat enclosed in
rubber into seal cavity on seal plate. Use a cardboard washer to protect polished surface when pushing against ceramic seat with any object. Be sure to remove cardboard washer.

2.Carefully slip seal plate over shaft so as not to disturb seal position in seal plate. The seal plate must be orientated during assembly so that the two holes are on a horizontal line across the motor shaft and the
(4) locating pins on the back of the seal plate line up with the tabs on the motor housing (Figure 15). This placement should be done to ensure proper draining and priming.
3.Place rotating shaft seal member in position on impeller and press into place. Take care not to press against polished seal surface.
4.Position impeller on shaft and tighten securely (Figure 16).

5.Secure diffuser to seal plate using the two cap screws. Be sure the screws are orientated on a
horizontal line as described in Step 2.
6.Carefully position pump housing (volute) gasket over the diffuser onto the seal plate. In all convertible applications the seal ring must also be positioned on the diffuser. In all shallow well applications care must be taken that the o-ring is clean and properly positioned on the venturi. Cleaning and positioning makes a good seal inside the diffuser when assembled.
7.Assemble the pump housing (volute) to the motor using the four cap screws. Be sure the pump
housing (volute) gasket is positioned correctly and tighten the screws securely.
NOTE: Shaft must rotate freely and motor end cap should be secured before operation.
