Thank you for having selected an Iwaki America WMD-100 Series magnetic drive pump. This instruction manual deals with the correct handling, maintenance, inspection, and troubleshooting procedures for the WMD-100 magnetic drive pump. Please read through it carefully to ensure the optimum performance, safety and long service of your pump.
Unpacking and Inspection Open the package and check that the product Iwaki conforms to your order. Also, check each of the Mag-Drive Pump following points. For any problem or WMD-100 MODEL inconsistency, contact your distributor at once. HEAD (FT.) CAPACITY (GPM) 1.
1. Do not operate the pump dry. The sliding parts used in the WMD-100 series pump are lubricated and cooled by the fluid being pumped. Never operate the pump dry or with the valves on the suction side closed. Otherwise, the inside of the pump will be damaged.
4. Maximum system pressure rating is 31.0 PSI (2.2 kgf/cm 5. Influence of temperature. The pump itself may not suffer a change in performance due to temperature fluctuation. However, the liquid may change in terms of viscosity, vapor pressure, and corrosive properties. Pay special attention to changes in liquid characteristics as a result of temperature fluctuation.
C. Fluids of high specific gravity CANNOT be pumped. See pump specifications for more information. D. The impeller may decouple from the drive magnet for several reasons: e.g. temperature, viscosity or specific gravity are too high. This is usually indicated by initial pumping, then a complete cut off of flow.
¦ Magnet Capsule/Impeller Installation (for WMD-100F pumps only) 1. The magnet capsule/impeller (wrapped in bubble pack) will be found in the same box that the pump was shipped in. It was removed to protect the silicon carbide ceramic bearing components from damage during shipment.
