bar) and hold for 10 minutes.
3.2.3. Drain.
3.2.4. Complete assembly per Section 2.9.3.
4. ROTOR ASSEMBLY BALANCING
Dynamic balancing of the pump's rotating assembly is necessary to eliminate excessive
out-of-balance conditions which can cause vibration damage to the pump. Although each
pump is dynamic balanced at the factory prior to shipment, factors, such as a change in
the fluid specific gravity or extensive repairs on the pump may require the rebalancing of
the rotating assembly. The following instructions are applicable to a completely
assembled rotor assembly as listed on figure 2.4.
4.1. Completely fill rotor cavity with fluid of required specific gravity. Plug rotor cover opening.
4.2. Position half key in driveshaft keyway.
4.3. Two plane balance using surfaces indicated by A and B on figure 4.0. Trim balance to 1/2 of the
out of balance by drilling as indicated on figure 4.0. Balance within .20 in-oz (158 mm-g) max at
975 to 1000 rpm.
Caution:
Sufficient guarding should be used when balancing the rotating
assembly.
4.4. Drain the rotor cavity and remove the rotor cover per Section 2.7.5.14 and 2.7.5.15.
