Installation & Connection

Handling

• When lifting the pump, use the motor eyebolts.

Installation

• The pump should be installed in a well ventilated and frost-free position. The distance between pumpmotor and other objects should be at least 6 inches in order to have enough air to cool the motor.
• The inlet pipe shall be as short as possible in order to reduce the head loss of the inlet.
• Ensure that the check valve is installed in the pipe line system before the pump is installed. If pump is used for boiler water supply, a check valve must be installed in the piping between pump and boiler.
• Pump shall be installed in a concrete base or other similar base with suitable height. It can also be installed in fixed grounds or fixed brackets on the wall.
• Pay attention not to let the weight of pipe system on pump to prevent pump from damage.

When installation, motor is not allowed to be hung upside down.

• Arrow on the inlet and outlet chamber shows the direction of flow of liquid through the pump. Check whether the liquid can flow easily before starting pump.
• Before pump installation, the inlet pipe line shall be cleaned. If there is impurities in the pipe, it is necessary to install a strainer at 20 – 40 inches in front of the pump inlet (particularly recommended for pump with flow less than 8 m3/h).
• The air locks shall be avoided when installing the inlet pipe line. See figure 3.
• If the outlet globe valve might be closed (or the flow is decreased to be zero), a bypass shall be installed in outlet pipeline to ensure adequate lubricating and cooling water to pass the pump.
  

Electrical connection

• The electrical connections should be carried out by an authorized electrician.
• To make sure the motor is suitable for the power supply, cables of the motor must be connected to power supply according to the figure on the terminal box and the motor nameplate.
• Motor shall be connected with a fast and effective motor starter, to ensure that the motor will not be damaged by lack of phase, unstable voltage or overload. The motor shall be earthed reliably.

Before take apart the terminal box cover or dismantle pump, make sure that the power supply is switched off.

Electrical connection and safety devices

• The pump units should be connected to the power supply by the appropriately rated power cables according to the motor ratings.
• The pump units should always be equipped with safety devices as required in the standards (EN 809 and/or EN 60204-1) as well as by the national rules of the country where the pump is used.
• Despite the rules of any country, the power supply to the pump unit must be equipped with at least following electrical safety devices with appropriate ratings:
• Emergency switch.
• Circuit breaker (as a supply disconnecting (isolating) device as well as an overcurrent protective device).
• Motor overload protection.

Start-up, Operation & Maintenance

Before opening the terminal box, please shut off the power supply to prevent an electric shock.

Before opening the coupling guards, stop pump first to prevent body injuries.

When installing the pump, please fix the foundation bolts to prevent pump from falling.

Please fill grease to the pump when it required. For motor power is less than 7.5 HP, it is free of  filling grease. For motor power is equal or bigger than 7.5 HP, please fill grease every 5000 running ‘1 hours.

Read the label on the cylinder carefully before start-up.

Do not start the pump until it has been filled with water or liquid fully.

• Fill water in pump in inverse pouring system.
• Close the pump outlet valve, release air vent screw on the pump head, and open the inlet valve slowly until stable water flows from the air vents-crew. Then fasten the screw.
• Open the check valve completely in the inlet pipeline. In open system, fill water in pump when liquid surface is lower than pump. (A check valve shall be installed in the inlet pipe).
• Close the pump outlet valve, release air vent screw and fill the liquid in pump through the air vent screw hole until the pump and inlet pipe line are filled with water fully.
• Fasten the air vent screw again.

Check the rotary direction.

• Switch on the power supply and view the rotary direction by viewing the motor fan. Arrow on the pump head indicates the correct direction of rotation. That is, from the motor end, pump shall run counterclockwise.

Check before pump start-up.

• Check whether the foundation bolt is fasten.
• Check whether pump is filled with water fully.
• Check whether the voltage of power supply is correct.
• Check whether it turns correctly.
• Make sure that all pipe lines are connected tightly and can supply water normally.
• The valves in the inlet pipe line are completely opened and the outlet valve shall be opened slowly after the pump is started up.
• Check the operation pressure if pressure meter is installed.
• Check all the controls for normal operation. If the pump is controlled by pressure switch, check and adjust the starting pressure and stopping pressure. Check the full load current to make sure it not surpasses the max. current.

Frequency of pump starts. Pump should not be started too frequently. It is suggested pump shall not be started more than 100 times per hour if the motor power is less or equal to 5 HP. When motor power is big than 5 HP, pump shall not be started more than 20 times in one hour. If pump starts and stops too frequently, control device shall be checked and adjusted to make pump not start and stop too frequently. Also, it is necessary to check the installation.

Suggestion: When pump running, flow should be controlled at the range of 0.5 – 1.3 times of rated flow.

Pump which is installed according to this installation manual will work effectively and require a
little maintenance.

• Mechanical seal will be adjusted automatically, the moving part and stationary part is lubricated and cooled by the transferring liquid. When replace the mechanical seal, the user don’t need to disassemble the motor for power bigger than 10 HP.
• The bearing in pump is lubricated by the transferring liquid.

Frost Protecting. Pump can be used in the system with anti-frozen measures to water. If the pump is installed in easily frozen place, suitable antifreeze shall be added to the transferring liquid to prevent pump from being damaged. If antifreeze is not used, pump shall be stopped when it is frozen. Pumps which are not being used should be drained.

The following should be checked regularly for pump.

• Pump working and operating pressure.
• Possible leakage.
• Possible motor overheat.
• Cleaning/ replacement of all strainers.
• The switch off time of motor when overload.
• Frequency of starts and stops.
• All control operation.

If malfunction is found, check system according to “Fault Finding & Solution Chart’~

Pump shall be cleaned and kept appropriately when it is not used for a long time.
Pump shall be prevented from being corrupted and damaged in storage.
