- Introduction: The mRoy pump is a reliable, controlled volume pump with a hydraulically actuated diaphragm design, available in two frame sizes, mRoy A and mRoy B.
- General Information: The pump's capacity can be adjusted manually or automatically, maintaining a repetitive accuracy within ±1% under constant conditions. It is suitable for handling corrosive or toxic chemicals and light slurries with viscosities up to 200 S.S.U. (40 cps).
- Pump Characteristics: Utilizes a plunger to displace hydraulic fluid, actuating a PTFE diaphragm. Double ball check valves ensure metering accuracy, with capacity control achieved by adjusting the hydraulic fluid volume.
- Pump Performance: Consistent metering accuracy is maintained by keeping the hydraulic oil volume constant, with mechanisms for air or vapor bleeding, oil replenishment, and temperature-induced oil volume changes.
- Unpacking/Inspection: Guidelines for safely unpacking and inspecting the pump upon delivery.
- Safety Precautions: Important safety measures during installation and operation.
- Pump Mounting/Location: Recommendations for optimal pump placement and mounting.
- Outdoor Installations: Special considerations for outdoor installations.

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 supply...
