Operation
Manual 1861 Rev C p/n 001861 0000
The following pump operating conditions should be
within the limits shown in
Specifications on page
4
:
• Maximum Process Inlet Temperature
• Process Discharge Temperature
• Oil Temperature
• Grease Temperature
Cooling Medium Differential Temperature is
determined by subtracting the Supply temperature
from the Discharge temperature. For water,
differential temperature must be within 12.6°F
(-10.8°C).
Observe other operating conditions, as well,
such as noise, vibration, and motor current draws
(amps).
STOPPING THE PUMP
1. Before disconnecting the motor power, close
the process inlet isolation valve.
2. If the process gas or vapor is corrosive or
hazardous, introduce inert gas, such as
nitrogen or argon, into the pump inlet for
20 to 30 minutes to purge out the residual
process gas or vapor from the pump internals
before disconnecting the motor power.
Ssee
Start/Stop (Cleaning) Purges on page 12
for more information.
All other pumps should undergo a 10 – 20
minute post-process drying operation before
the motor power is disconnected.
See Post-
Process Dry Operation on page 14
for

3. Shut down the pump.
4. Shut off the cooling liquid supply.
If the pump must be shut down for a long period of
time when freezing weather is expected and water
is used as a cooling liquid, drain the pump cooling
jacket through the cooling jacket nozzles.
LUBRICATION
Any lubricants used must be high-grade petroleum
products that contain oxidation inhibitors, rust
preventatives, extreme-pressure additives, etc.
OTE:
