    Installation 1. Before installation Precautions for electrical wiring and pipework CAUTION Do not drop, hit or drag the pump during carrying in or installation. Caution Poisoning may result when handling an odorous or a harmful liquid. Keep good ventilation in a work area. The front case, rear case and base are plastics.

  • Page 16: Installation

    Installation 3. Installation Check if installation doesn't adversely affect facility, surrounding equipment and the pump. Install the pump according to the following instructions to ensure the optimum performance, safety and service. If the pump unit is not anchored to the foundation and if the motor unit is heavier than the pump unit, the entire pump leans towards to the motor.

  • Page 17: Pipework

    Installation 4. Pipework Foreign matters such as sand and scale may enter pipework while you are working. They may cause fatal damage to the pump. Be sure to blow them out before operation. Also, do not apply adhesive too much or leave a screw or nut. If pipework directory weighs on the pump, plastic parts may be deformed.
  • Page 18 Installation 6. Do not make an arched line in order to prevent air from being trapped. A suction line right before the pump inlet should be laid on a rising gradient of 1/100 toward the pump. 1. A discharge pipe bore is related to pipe resistance Pipe resistance rises too high to obtain an intended flow if a discharge pipe bore is too narrow.
  • Page 19 Installation (This table is based on use of metal pipe flanges with rubber gaskets.) Bolt size Try not to apply a heavy load to the inlet and outlet flanges. Permissible piping weight and moment to the pump are as below. Permissible stress to outlet flange Permissible stress to inlet flange Pipe dia.

    Operation 1. Operational precautions CAUTION shut off a suction valve during operation. This may damage internal parts. Prohibit . An abnor- mal sound of water flowing through a pipe or a significant pressure change (see a pressure gauge) is a sign of cavitation. Also do not continue to run the pump when air is sucked from a suction line.

  • Page 23: Before Operation

    Operation WARNING Do not remodel the pump A remodelled pump will not be warranted. Also, we are not responsible for personal injury or property damage due to any modification. Prohibit CAUTION Be sure to prime the pump before operation Always prime the pump when the pump is empty, for example, the pump is used for the first time or after dismantlement/assembly.
  • Page 24 Operation 3. ON-OFF operation Frequent ON-OFF operation damages the pump, especially in self-priming operation. Do not make ON-OFF opera- tion more than six times per hour. 4. Handled liquid - Observe the next points 1. Slurry :Slurry can not be handled. 3.

  • Page 25: Preparation

    Operation 3. Preparation 1. Check the pump and pipework before operation. a. Check there are no foreign matters in the supply tank and pipework. If foreign matters are stuck in a suction line, the pump may break. Do not leave any waste of bond, sealing materials and screws/nuts as well. b.

  • Page 26: Operation

    Operation 4. Operation Operate the pump by the following procedure. Operation Procedure Remarks Close or open valves. Open suction valves fully. Close a discharge valve fully (in a flooded suction system). Open discharge valves fully (in a suction lift system). Prime the pump.

Always check for leakage before pump operation. Do not run the pump when liquid leaks. CAUTION The pump unit mounting bolts/nuts may loosen in the initial operation phase or under an operating condition where the temperature fluctuates greatly.
  • Page 32 Maintenance To ensure efficient and smooth operation, perform periodic inspection. Be careful not to damage internal sliding parts and plastic parts when dismantling the pump. The magnetic force of a drive and a driven magnet is strong. Be careful not to catch the finger. Do not put electrical devices such as a watch and a mag card close to those magnets.
