Page 18: Handling Instructions
1. Handling Instructions (Observe all the following instructions to prevent injuries and accidents.) Warning Do not operate the pump for the circulation of hazardous mediums (such as explosive, combustible, flammable, or toxic substances, as well as corrosive or irritating substances considered harmful to human health). Caution Read the following information prior to installing the pump. - Page 19 No remodeling Never try to remodel the pump. This may cause a serious accident or damage. No disassembly or repair Users are allowed to disassemble and repair the pump to the degree of the given description in "Disassembly and Assembly" in this manual. No dry running operation Dry operation of the pump (pump operation without liquid inside) may cause damage to the pump internally.
- Page 20 [12] Tolerable pressure and temperature limit • Maximum pressure resistance Maximum pressure V type (PVdF) kgf/cm The table on the left shows the maximum pressure resistance of each model. Take care that the discharge E type (ETFE) pressure does not exceed the maximum pressure P type (PFA) resistance.

3. Piping Tightening torque for piping flange of pump. Recommended bolt size for piping flange is M16 and tightening torque is 78.4N·m. (In the case of steel flange with rubber gasket.) Load of piping and momentum of piping for MDE The permissible stress and moment applicable to pump connection arrangement are as shown below. - Page 23 Example of piping Discharge pipe (Support the pump to keep the (11) Suction pipe (pipe diameter: D) pump free of piping load.) (The horizontal section should be as short as Valve possible and there should be an ascending Check valve gradient of 1/100 toward the pump.) Pressure gauge (12) Pipe support...
- Page 24 b b Suction piping The suction pipe should employ the flooded suction method if possible. The shortest pipe possible, with the minimum number of bends, should be used. Arrange a proper support under the suction pipe such as an expansion joint or the like so that the weight and thermal stress of the pipe are not applied to the pump. Attach the coupling on the suction pipe carefully so as not to allow air inside the line.
- Page 25 If the diameters of the pump suction port and the suction pipe are different, use an eccentric reducer pipe. Connect the eccentric reducer pipe so that the upper surface is level. In any case, never use a suction pipe with a diameter smaller than that of the suction port.

Page 26: Wiring
It is recommended that a gate valve be installed on the discharge pipe for the adjustment of discharge volume and for the prevention of overload onto the motor. When installing both a check valve and a gate valve, the check valve should be positioned between the pump and the gate valve. Do not fail to install a pressure gauge on the discharge piping. -
Page 27: Operation Step
5. Operation Step b b Operation instructions Never operate the pump dry or with the suction-side valve (gate valve) closed. Otherwise, the inside of the pump will be damaged. In the event of cavitation, stop the pump within a minute. In addition, do not continue pump operation with air mixed into the suction side. - Page 28 [10] Sound generated by pump The level of sound generated by each type of pump is shown in the table. Arrange muffling measures in accordance with the sound level. The procedure for sound measurement conforms to the EN 31201 (ISO11201). (dB) Model MDE32...

In this step, be careful not to damage the seal surface and gasket (400.1). [5] Remove the impeller (230) from the split plate and magnet capsule unit (858) by rotating it counterclockwise.
- Page 41 b b Assembly The pump should be assembled by carrying out the steps of disassembly in reverse, as described below. Pay attention to the following points. Keep the sliding and sealed parts clean so that they are free of dust or scratches. When assembling these parts, be sure to attach them in the correct positions.
- Page 42 [1] Install the split plate from the spindle side of the magnet capsule unit (859). Be careful not to damage the sleeve or the sliding section of the bearing. Next, attach the O ring (412) to the magnet capsule unit (859) and after applying a proper quantity (just enough so as not to drip) of adhesive to the threaded portion (three peripheral threads in the threaded portion of the...
