READ THESE INSTRUCTIONS CAREFULLY

Read these installation instructions in detail before installing your pump. Be sure to check the following:

1. Be certain the motor is connected for the correct line voltage being used (check motor nameplate).

2. Be certain the pump is completely primed before starting. Otherwise damage may occur to the seal.

Every pump is tested before leaving the factory, and its performance depends largely on the installation.

GENERAL SAFETY INFORMATION

1. Follow all local electrical and safety codes, as well as the National Electrical Code (NEC) and the Occupational Safety and Health Act (OSHA).

2. Replace damaged or worn wiring cord immediately.

3. Do not kink power cable and never allow the cable to come in contact with oil, grease, hot surfaces or chemicals.

4. Protect the power cable from coming in contact with sharp objects.

5. Be careful when touching the exterior of an operating motor - it may be hot enough to be painful or cause injury.

6. Make certain that the power source conforms to the requirements of your equipment.

7. Always disconnect power source before performing any work on or near the motor or its connected load. If the power disconnect point is out-of-sight, lock it in the open position and tag it to prevent unexpected application of power. Failure to do so could result in fatal electrical shock.

INSPECTION AND STORAGE

When unpacking the unit, inspect carefully for any damage that may have occurred during shipment. If the unit is received sometime before it can be used, it should be inspected, recrated and stored in a dry location.

LOCATION IMPORTANT: In installations where property

damage might result from an inoperative or leaking pump due to power outages, discharge line blockage or any other reason, a back-up system (s) and/or warning system (s) should be used.Install a gate valve and union in the suction and discharge lines. For removal of the pump for service, close the gate valve and disconnect the union.

1. Locate pump as close to the fluid source as possible.

2. Place unit where the motor electrical components and piping are protected from the weather and extremes of heat, humidity and below freezing temperatures.

3. Mount unit in a dry location that is easily accessible for inspection and maintenance. If a dry location is not available, mount it on a foundation well above the wet floor.

4. Allow ample clearance around unit for free air circulation.

5. CJ103 Series pumps incorporate a discharge port on the pump casing that can be adjusted in 90 increments. If necessary, adjust the discharge port to accommodate the specific application. Pump performance will not be affected by the position of the discharge port.

SUCTION LIMITATIONS

1. Units are non self-priming. Normally after being primed the total suction lift of the pump is 25 feet. Suction lift varies depending upon elevation (altitude) and water temperature. See Practical Suction Lift chart.

2. Where liquids at or near their boiling points are being handled, the supply must be located above the suction, so that the available NPSH will be greater than that required by the unit.

This table gives the maximum permissible suction lift or the minimum head permitted on the suction side of a pump at various altitudes and liquid temperatures. A minus sign before a number indicates suction lift. A plus sign before a number indicates minimum head. These figures are to be used as a guide.

PIPING

1. Use galvanized piping, rigid plastic or other suitable pipe that will not collapse under suction or rupture due to pressure.

2. The diameter of the suction and discharge pipe should be no smaller than the corresponding tappings of the pump (see Figure 3 & 4). If long runs are encountered larger pipe should be used. Smaller pipe will reduce the capacity of the pump.

3. All joints and connections should have Teflon tape or pipe sealing compound (male threads only) applied and drawn up tightly.

The entire system must be air and

water tight for efficient operation.

PUMP INSTALLATION

Refer to Figures 5, 6, and 7 for typical installations. Both the suction and discharge pipe should be supported at a point near the pump to avoid strains being placed on the pump.

Pipe Support

5. On suction lift installations, a foot valve located in the water or a check valve located as close to the water as possible will reduce priming time of the pump and help maintain prime. A strainer must be used on the suction line to filter out dirt and debris.

6. A priming tee installed in the pump discharge port allows water to be poured into the pump case and suction piping, which is required for priming on suction lift installations.

7. Install a gate valve and union in the suction and discharge lines. For removal of the pump for service, close the gate valve and disconnect the union.

Do not use a globe valve or other restricting type of valve at the discharge. This will seriously restrict the capacity of the pump.

8. Pressure Gauges - Properly sized vacuum or

pressure gauges can be installed in both the suction and discharge pipe. The gauges will enable observation of the pump’s performance as well as detecting cavitation, vapor binding or other unstable operation.

1. If the pump is used as part of a permanent installation, secure to a rigid foundation with appropriate fasteners.

2. Locate the pump as close to the water as possible, keeping the suction pipe as short as conditions permit.

3. Avoid dips or pockets in offset piping or air will accumulate at high points which will make priming difficult.

4. The suction pipe should slope upward to the pump inlet. A horizontal suction line must have a gradual rise to the pump.

Use only components that are rated higher than shut-off pressure of the system. Do not exceed the pump’s maximum case pressure as listed in the following table.

capacity must be installed on any installation where the pump pressure can exceed the pressure tank’s maximum working pressure or on systems where the discharge line can be shut-off or obstructed. Not providing a relief valve can cause extreme over pressure which could result in personal injury and/or property damage.

voltage. If in doubt consult a licensed electrician.

Use wire size specified in wiring Chart E. If possible, connect pump to a separate branch circuit with no other appliances on it. If wiring diagram on motor model plate differs from diagram shown in figures 8, 9 & 10, follow diagram on motor.

All wiring should be performed by a qualified electrician and in accordance with the national and local electric codes.

WIRING

1. Motor voltages will vary depending upon the

motor horsepower and phase. Refer to the motor nameplate and the Motor Data Chart (Chart C) for voltage and electrical data.

Make certain that the power supply conforms to the electrical specifications of the motor supplied. Failure to do so may cause premature motor failure and will void the warranty.

2. To change voltage, remove the rear access

cover, which is held in place with two (2) screws. For proper electrical connection, refer to the connection diagram located on the motor

Replace rear access cover before starting or operating pump. Failure to do so can result in personal injury.

MOTOR PROTECTION

1. All single phase motors have built in thermal

protection for all voltages. The overload protects the motor against burnout from overload of low voltage, high voltage and other causes. The device is automatic and resets itself once the temperature has dropped to a safe point. Frequent tripping of the device indicates trouble in the motor or power lines and immediate attention is needed.

Never examine, make wiring changes or touch the motor before disconnecting the main electrical supply switch. The thermal device may have opened the electrical circuit.

2. Three phase motors do not have a built in

thermal protection. It is recommended that a properly sized magnetic or manual starter (both with properly sized heaters) be used with all three phase motors. Install starters following instructions of the starter manufacturer. See Figure 11 for magnetic starter wiring diagram.

3. All motors (single and three phase) should be

equipped with a correctly fused disconnect switch to provide protection. consult local or national electric codes for proper fuse protection based on motor data chart (see Charts C & E).

PRIMING

1. Before starting any centrifugal pump, it is

absolutely necessary that both the casing and suction pipe be completely filled with liquid. This priming can be accomplished by any of the following methods:

2. When the liquid supply level is above the center

line of the pump, it is primed by opening the suction and discharge valves. The inflowing liquid will displace the air and fill the suction

line, pump casing, and discharge line up to the level of supply.

3. Where the pump is operating with suction lift and the suction line is equipped with a foot valve, remove the priming plug from the discharge tee (see Figures 5-8) and fill the pump body and suction pipe completely with water. No additional water will be needed for subsequent start-ups unless the pump body is drained.

4. After the pump is turned on it will require 2-5 minutes before all air is evacuated from the suction line and water begins to flow. If there is no water after 5 minutes, turn the pump off and check the following:

5. Any air leaks on the suction line must be eliminated.

6. Suction pipe inlet should be a minimum of 5 feet below the water level.

7. Total suction lift cannot be greater than 25 feet.

8. Any restrictions in the discharge pipe, such as a closed valve must be eliminated.

NOTE: Unit must be full of liquid before operating. Never run dry, or against a closed discharge. Dry running or running unit against a closed discharge will cause damage to the shaft seal. Do not pump dirty water or abrasive liquids, otherwise the same may occur as if running dry.

MOTOR ROTATION

1. Single phase models are one (1) rotation only (counterclockwise when facing the pump suction tapping) and cannot be reversed.

2. Proper rotation of pump impeller is critical for three phase pumps. Pump motor should turn counterclockwise (CCW) when facing pump suction tapping. Momentarily “bump” (apply power for less than a second) the motor to check for proper rotation. To change rotation on three phase units, interchange any two (2) incoming line (power) leads.

SINGLE PHASE MOTORS THREE PHASE MOTORS

MAINTENANCE Lubrication

The pumps and motors require no lubrication. The ball bearings of the motor have been greased at the factory. Under normal operating conditions they should require no further greasing.

Winterizing your Pump

Cracked pump housings caused by freezing are not covered by warranty. To protect your pump from freezing, for best results remove the pump and store in a warm environment. If pump cannot be removed from your system, remove both drain plugs, one on the suction flange and one at the bottom rear of the pump (see fig 2 in the instructions.) Allow the water to completely drain from the pump. Re-install both drain plugs and fill pump with RV type antifreeze. Antifreeze also acts as a rust inhibitor. It will help keep rust build up to a minimum and seals lubricated inside the pump while it is not in use.

ROTARY SEAL ASSEMBLY REPLACEMENT Disassembly

When disassembling the pump, care should be taken not to damage the gaskets. If torn or damaged, replace with new gasket (see parts list).

1. Remove the four (4) pump through bolts that

connect the mounting ring to the pump body. Remove the pump body, taking care not to damage the gasket or o-ring.

2. Remove the impellers. CJ103 Models are

single stage units, having one impeller. Using a 9/16” open end wrench, hold the motor shaft flat and unthread the impeller by turning it counterclockwise. The motor shaft flat area is located in the middle of the mounting ring.

3. CJ101 models are multi stage units, having

two or more impellers and one or more intermediate stages. Using an 11/16” open end wrench on the motor shaft extension flat, remove the first impeller by turning or

counterclockwise. Remove the intermediate stage (stages) taking care not to damage the gasket (gaskets) and unthread the remaining impellers.

4. Remove the mechanical seal assembly. The rotary portion of the seal assembly (carbon ring, Buna-N gasket and spring) will easily slide off the end of the shaft. The ceramic portion can be pried out of the rubber seating using two (2) screwdrivers (see Figure 13).

Reassembly

The precision lapped faces of the mechanical seal are easily damaged. Handle the replacement seal carefully. Short seal life will result if seal faces (ceramic & carbon) are nicked, scratched or dirty.

1. Clean the seal cavity of the mounting ring and

the motor shaft thoroughly.

2. Apply liquid soap (one drop only) to the outside

of the Buna-N gasket that houses the ceramic seal seat. With thumb pressure, press the ceramic seat, polished face up, squarely into the seal cavity (see Figure 14).

3. If seal does not seat squarely, remove and

reclean the seal cavity. Place a cardboard washer over the polished seal face and carefully press into place using a piece of pipe or tubing (see Figure 15). Discard cardboard washer.

4. Apply liquid soap (one drop only) to the inside

diameter of the rubber drive ring. Slip rubber drive ring (carbon face down) and the spring over the shaft.

5. Reassemble the pump by following the reverse

order of the disassembly instructions.

MOTOR REPLACEMENT
