J Line Pump
Horizontal Double Suction Centrifugal Pump – API 610 Process Pump
49 V1.032818
Check all equipment for proper lubrication and correct rotation.
Check the oil level and validate that the correct oil grade is used (in oil lubricated pumps).
Check that the surface temperature of the bearing housing. They should not exceed 185 °F
(85 °C).
Check that the pumping unit is running quietly and without vibrating.
Unusual or too loud noises point towards a possible fault.
Monitor the power consumption of the drive motor. Low or excessive power consumption
indicates a possible fault.
Check the sealing system:
a. Refer to the seal manufacturer for his estimate of maximum acceptable leakage
rate, as this will depend on application, design, location and the sealed liquid
characteristics.
b. If leakage is excessive, switch the pump off as quickly as possible, isolate the pump
by closing the discharge and suction valves or using some other approved method
designated as safe for your system, and check the rotating seal ring and the
stationary seal ring.
If the sealing system of the mechanical seal fails, the pump must be taken out of
operation immediately.
The pump may only be operated under the minimum operating range for short
periods. The minimum pump flow is given in the characteristic line.

When the pump has reached operating temperature and pressure,
1. Stop pump.
2. Check alignment and reset the equipment, if required.
3. Dowel the pump.
4. Dowel the driver.
