IMPORTANT INFORMATION - READ ME FIRST! Model Number and Serial Number Record the model number and serial number below for future reference. This is important information when ordering replacement parts or when technical assistance is required. The numbers are found on a label located on the motor adapter.
Installation/Operation Precautions CAUTION: This pump should never be operated without liquid in the casing. It is recommended that run dry protection be used. Optional electronic power monitors are available to help protect against run dry. If the pump has a PTFE or ceramic bushing, IT CANNOT BE RUN DRY WITHOUT CAUSING DAMAGE TO THE PUMP. However, the pump can operate without liquid in the casing if the pump has a carbon bushing.
Section I - Assembly 4. Make sure the motor shaft is clean and free of burrs. Coat the motor shaft with anti-seize compound. If not installed insert key supplied with motor into keyway on motor shaft. Pumps with Motors NOTE: The outer drive is precision machined and has a bore tolerance of +0.001/-0 inch. It may be necessary to tap the drive on with a soft mallet. Proceed to Installation Section Pumps Without Motors 5.
8. Install the pump end on the motor/drive magnet assembly. Carefully slide the pump onto the drive magnet assembly. See figure 7. the Phillips-head screwdriver. Hand tighten screws being careful not to over tighten. See figures 11 & 12. 9. Secure the pump to the motor adapter flange (item 6) with (4) motor adapter screws (item 8). Hand tighten screws being careful not to over tighten. See figure 8.
Motor/Electrical 2. Open the inlet (suction) and discharge valves completely and allow the pump to fill with liquid. Install the motor according to NEC requirements and local electrical codes. The motor should have an overload protection circuit. 3. Close the discharge valve. 4. Turn the pump on. Slowly open the discharge valve. Adjust the flow rate and pressure by regulating the discharge valve. Do not attempt to adjust the flow with the suction valve.
wear protective clothing, eye protection and follow standard safety procedures when handling corrosive or personally harmful materials. Proper procedures should be followed for draining and decontaminating the pump before disassembly and inspection of the pump. There may be small quantities of chemicals present during inspection. WARNING: Magnetic force hazard. This pump should only be disassembled and assembled using the recommended procedures.
Section VI - Reassembly 1. Place impeller assembly (item 3) into the motor adapter / barrier (item 4). See figure 31. Figure 22 2. Install o-ring (item 2) onto housing (item 1). Lubricate the oring with P80 or a compatible lubricant. If o-ring will not stay in place it may be necessary to roll the o-ring under when installing it on the housing. See figure 32. Figure 23 3.
