This manual covers the installation of the basic drive con- figuration for the 9940-9750NRL centrifugal pump. Consult the manufacturer of your motor or engine for additional infor- mation. Read all instructions and general safety information before attempting to install or operate the pump. Mounting Belts and Pulleys Mount pulleys as close to the pump and motor engine shaft bearings as possible. Check the alignment with a straight edge as shown in Fig. 1. Make sure that the belt has proper tension. (Too much tension will cause bearing wear; too little will cause slippage.) See Fig. 2. Check with...

The pump is non-self-priming! The pump must not be run dry! Hypro recommends a flooded suction. If this is not possible, use a foot valve and prime the pump. (See the figure above.) 1. Position the pump as near as possible to the source being pumped. A flooded suction situation is preferred. The pump is not self-priming, therefore, if the fluid level is below the pump, a foot valve must be installed and the pump primed prior to start-up. (See the figure above.)2. Mount the motor base to a secure, immobile foundation. 3. Use only plastic fittings on both the intake and discharge ports. Seal the...

Disassembly 1. Shut off the power to the motor before disconnecting any electrical wiring from the back of the motor.2. Disassemble the body-motor assembly from the volute. (The volute may be left in-line if you wish.)3. Remove the cap covering the shaft at the back motor and, with a large screwdriver, prevent the shaft from rotating while unscrewing the impeller.4. Remove the ceramic piece from the impeller. 5. Detach the body from the motor. 6. Remove the carbon-graphite seal from the body by press-ing the seal out from the back. Do not dig the seal out from the front. Pump End Assembly 1....
