maintain the pump oil temperature above 30°F
(-1°C).
2.6 FLANGE MOUNTED MOTORS
If a ange mounted motor option was selected for
the mRoy pump, the customer supplied motor will
need to be mounted to the pump. This is generally
a straight forward procedure. Refer to Figure 17 or
18, as appropriate.
When mounting the motor to a Close Coupled
Flange, 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.
2.7 ELECTRICAL CONNECTIONS
Check to be sure that the electrical supply
matches the pump motor nameplate electrical
characteristics. Motor rotation must be counter
clockwise when viewed from the top end of the
motor.
ON SINGLE-PHASE
PUMP MOTORS THE
ROTATION WILL BE DETERMINED AT THE
FACTORY AND MUST NOT BE CHANGED. ON
THREE-PHASE PUMP MOTORS THE ROTATION
MUST BE DETERMINED AT THE TIME OF
INSTALLATION AND PRIOR TO START-UP.
OPERATION WITH THE WRONG ROTATION WILL
DAMAGE THE PUMP AND MOTOR AND VOID THE
WARRANTY. SHAFT ROTATION CAN BE
OBSERVED BY REMOVING THE COVER PLATE
OVER THE ELECTRICAL CONNECTIONS.
2.8 MOTORS
Adequate power is provided to the simplex mRoy A
pump by the standard ¼ HP (0.25 Kw) motor. The
motor is normally a totally enclosed non-ventilated,
type, that is mounted on a 56C-face ange or IEC
Frame 71 ange. The gear reducer (worm shaft) ts
onto the standard motor without using a coupling.
On the larger mRoy B (Figures 10-13), the normal
temperature rise for these motors is 50°C above
ambient temperature, and it can be expected
that these motors will appear to operate at higher
temperatures than are normally experienced.
However, there is no cause for worry if the following
precautions are observed:
1. The motor is placed where there is adequate
ventilation and is protected against excessive
radiation from steam pipes and other heat
sources.
2. The overload heater in the starting device should
be correctly sized for motor full load current
rating as shown on the motor data plate.
Note: For a motor that is supplied by the
customer, Milton Roy is not responsible for any
damage resulting from an improper installation
or for a motor that is not suitable for the
selected environment.
2.9 PUMP LUBRICATION
CAREFULLY UNSCREW
TO REMOVE OIL
RESERVOIR CAP. DO NOT APPLY PRESSURE TO
JOG CAP FROM SIDE TO SIDE OR DIP STICK MAY
BREAK.
Oil is supplied for the average installation
(ambient temperature above 50°F (10°C). See
recommendation below for lower temperature.
Fill pump and gear box by slowly pouring the
recommended oil through the air bleed reservoir
opening until the oil level in the reservoir is level
with oil level mark on outside surface of reservoir.
Level can also be checked with dipstick on oil
reservoir cap. Recheck while pump is operating.
DO NOT OVER FILL AS
MOTOR DAMAGE CAN
RESULT.
