  • Page 11: Instructions For Safe Usage

    ● Instructions for Safe Usage  In order to use your Sanwa Magnet Drive Pump in the manner for which it was designed, be sure to read through and get a thorough understanding of the contents of this manual and the installation instructions before at- tempting to install, operate, perform maintenance or inspections.

  • Page 12: Precautions When Pumping Special Liquids

    Precautions When Pumping Special Liquids  Sanwa pumps are used in various industries. Our stainless steel magnet drive pumps in particular are frequently used for pumping hazardous liquids, and fluids which tend to produce food germs. Mishandling in any of these cases could lead to serious consequences such as bodily injury, loss of life or property damage.

  • Page 13: Transport And Unpacking

    ● Transport and unpacking 1. Transport  When transporting the pump, be careful not to drop it or let it fall. Take the appropriate method, such as picking up by two people or lifting by belt, to avoid risk.  Make sure the eyebolts (if the pump is equipped with them) are used to secure the pump during transportation.

  • Page 14: Preliminary Check

    ● Preliminary Check When your pump is delivered, you should check the following items:  Are all of the accessories included in the package?  Check the name plate to make sure the merchandise is as ordered.  Check to make sure the pump has not been damaged or the bolts and nuts loosened during transport.

  • Page 22: Pump Installation

    ● Pump Installation 1. Installation  The position of the pump should be finalized after considering the pump suction capacity. If the suction head is not enough, cavitations and ab- normal vibration/noise will occur.  The pump should be installed in a place which provides sufficient space for maintenance and inspections.

  • Page 23: Wiring

    3. Wiring  Power supply equipment, wiring and the earth terminal connection should be in accordance with technical standards for electrical equip- ment and inner wiring diagrams. Piping or the earth terminal connecting work performed by unqualified personnel is not only in violation of the law, but is extremely dangerous.

  • Page 25: Operation

    ● Operation 1. Pre-Operation Inspections (Be sure to turn the power off before performing inspections!) 1. Tighten flange bolts and machine base bolts. 2. Supply liquid after thoroughly cleaning the inside of piping and tanks. 3. Check if you can turn the motor by hand without supplying power. 4.

  • Page 26: Operation And Handling

     Be sure to completely close the gate valve of discharge pipe before starting the pump. 2. When the pump arrives at the specified speed, open the gate valve within one minute. 3. When the pump starts, check for abnormal noises, vibration, or rising discharge pressure.
  • Page 27  High Temperature If pumping hot liquids, do not place your hands or other parts of your body near the casing or frame adapter. Doing so could result in skin burns.  No-Load Operation Prohibited The bearings are lubricated by liquid pumped. Running the pump without liquid to be pumped should be avoided.
  • Page 28  If a power unit does not meet the power required, “decoupling” will be occurred and then the temperature of pump surface will rise up. Variation in Performance According to Viscosity  Discharge flow rate and the total head of pumps are lower for high viscosity liquids than when using fresh water, and more power is required to pump viscous liquids.

  • Page 29: Shutting Down

    Noise Level  Typical sound pressure levels measured in dB(A)(at 1m) are shown in the table below. (In case of using typical motor)  Pump noise level depends on a number of factors – the type of driver, the operating capacity, piping design and acoustic characteristics of the building. If the motor is driven by inverter, noise level will be increased.

  • Page 30: Maintenance And Inspection

    ● Maintenance and Inspection 1. Routine Inspection Item Advice Does the pump run smoothly Permissible amplitude of vibration for the without vibration? pump with 2P motor is 28/33µm as maximum 47/54µm, maximum pump equipped with 4P motor(60/50Hz). If abnormal noise is produced by the bearings or other parts, stop the pump immediately and check each part.

  • Page 35: Order Of Disassembly And Assembly

    3. Order of Disassembly and Assembly  The magnet coupling uses powerful magnets which attract metal and other magnetic materials. The workbench, therefore, should be made of wood or plastic.  We recommend the use of non-magnetic stainless steel tools for disas- sembling the pump.

  • Page 37  If pumping hazardous chemicals, be sure to wash the pump thoroughly after draining the liquid. A small amount of liquid will however remain in the screw, faucet joint and engaged parts inside the pump. If handling hazardous chemicals, be sure to wear protective equipment such as glasses and rubber gloves, and proceed with caution while disassem- bling the pump.

  • Page 38: Checking Parts Dimension And Clearance Gap

    4.Checking parts dimension and clearance gap  If the clearance between rotating and stationary components is out of limitation, it may happen that these component contact and resulting frictional heat entail excessive temperatures. Check the following dimensions, when disassembled. If measured di- mension exceed the allowance, replace damaged parts by new original spare parts.

In case of that opened impeller’s clearance is out of allowance by wear of bearing, replace bushing or thrust ring with new spare parts, even if they are within al- lowance range.
