1.3 PUMP CHARACTERISTICS For a general description of the mRoy pump you havepurchased, compare the model number and productcode printed on the pumps data plate (shown in Figure3) to the appropriate model number and product codeshown in Figures 4 through 6 and Figure 12. 1.4 PUMP PERFORMANCE The charts in Figures 8 through 10 show the perfor-mance ranges for all mRoy A & B frame pumps. If appropriate, refer also to the derating table shown inFigure 11. 1.5 PRINCIPLE OF OPERATION Pumping action is developed and controlled by fourbasic components as follows (Figures 1 & 2):1.The pump plunger...

Figure 1. Pump Operation With By-Pass Port Open Figure 2. Pump Operation With By-Pass Port Closed 2 The discharge capacity is adjusted from 0100% byrotating the adjustment knob that moves the controlspool (valve) ֓F so that the bypass port ԓH is closed atthe desired percentage of the total plunger stroke.When the control spool (valve) is adjusted to 100%capacity the bypass port will be positioned so that it isopened at the very end of the suction stroke. Then onthe pressure stroke, the bypass port is immediately closed so the entire plunger displacement is imposedupon the flexible...

2.5 FLANGE MOUNTED MOTORS If a flange mounted motor option was selected for themRoy pump, the customer supplied motor will need to be mounted to the pump. This is generally a straightforward procedure. Refer to Figure 18 or 19, as appro-priate.When mounting the motor to a NEMA 56C Close Cou-pled Flange (product code option SR, refer to Figure19), the motor mount plate (710) must be removed from the pump body and bolted to the motor. The motor/motor mount plate assembly can then be bolted to the pump. > 2.6 ELECTRICAL CONNECTIONS 2.1 UNPACKING/INSPECTION Check to be sure that the electrical...
