What to do if my Milton Roy Water Pump is making a pounding noise at high discharge pressure?
The pounding noise at high discharge pressure in the drive casing is due to fluid compressibility causing a reversal load on the gears at the end of the pressure stroke. This is not considered detrimental, so no action is needed.
Why does my Milton Roy mRoy B motor overheat and trigger thermal overload switches?
The motor overheats and triggers thermal overload switches for the following reasons: the power supply does not match the motor characteristics, so you should check the power supply against the motor nameplate data. Another reason might be overload caused by operating the pump above its discharge pressure, so you should check the operating pressure against the pump manufacturer’s data plate max. rating and correct the cause of the pressure abnormality.
What to do if my Milton Roy Water Pump delivery is not adjustable?
If your Milton Roy Water Pump delivery is not adjustable, consider the following: the flexible diaphragm may be punctured by foreign material, requiring you to replace the diaphragm; the O-rings on the control spool may be nicked, requiring you to replace the O-rings (note: you must use a special tool).
What to do if my Milton Roy mRoy B Water Pump is too noisy?
Pump valves must move to open and close, and they will make a clicking noise as they operate. These noises are sometimes amplified by natural resonances in the piping system. They are usually indications of normal valve functioning. If the pump internal relief valve is actuating, this can be caused by several issues. It may be due to excessive suction lift conditions, so you should lower the pump or raise the level of liquid. It may be due to insufficient suction pressure, so you should correct the poor suction condition. It may be due to a clogged or partially blocked filter or strainer in the suction line, so you should clean the strainer. It may be due to clogged or fouled suction or discharge check valves, so you should clean or replace them. Finally, it may be due to a blocked dischar...
