Description of BW250 Triplex Mud Pump|drilling pump

BW250 Triplex Mud Pump:

1. Be sure that the pump foundation is level and able to support the weight of the pump.

2. Install the pump as close as possible to the mud tank or pit to reduce drop in suction line. 

SUCTION SYSTEM 

1. The diameter of the suction line must be equal to or exceed the diameter of the pump suction connection.

2. Use as short a suction line as possible.

 3. Install the suction line in as straight a line possible. If turns are necessary use long radius ells.  4. Install a section hose in the suction line to isolate vibration. 

 5. Be sure there are no air traps or air leaks in the suction line. 

 6. Install a charging pump in the suction line. (See CHARGING PUMPS.) 

 7. Install a suction desurger to prevent mud cavitation. (Refer to FLUID END ACCESSORIES in Section 4 of this guide.) 

 8. Fully open all valves in the suction line before operating the pump.

Tips for PREPARATION:

 3. Remove the cover plates from the power end. 

 4. Inspect the power end for contamination. Clean as required.
