Why is my pool pump motor making a loud noise?

Why is my pool pump motor making a loud noise?

One of the most common causes for a noisy pump is that it’s running dry. If your pool water level has fallen below halfway on the skimmer faceplate, your pump might be sucking in air as well as water. This puts more strain on the pool pump, causing it to work harder—and louder.

How do I stop my pump from making noise?

To solve the issue, you can take the following actions:

  1. Throttle the pressure-side valves until the noises are eliminated.
  2. Trim the impeller diameter.
  3. Reduce pump speed.
  4. Add a flow recirculation line.
  5. Install a variable frequency drive and remove control valves.

How loud is pool pump?

A typical swimming pool pump runs in the range of 65-90 decibels, almost as loud as riding in a subway car. This can be a detriment to a pools outdoor pleasure. Even a small decrease in this sound can help tremendously.

How do I know if my circulating pump is bad?

Circulating pump not working?

  1. The water flow pipe isn’t hot despite the pump running.
  2. A water leak coming from the pump.
  3. The pump is making unusual noises.
  4. The pump casing feels hot.
  5. Some or all of your radiators aren’t heating up.
  6. You have no hot water.

How long does pool pump motor last?

Pool Pumps Your pool’s pump is the wet end of the operation, it houses the pump basket. Pumps should last through the initially installed motor and perhaps as many as two or three replacement motors, usually 10-12 years. Modern pumps are made of hard plastic and will over time warp.

What causes noise in a pump and system?

Noise in pumps and systems The noise emitted by pumps and systems is caused by vibrations in the piping and the pump casing. These vibrations interact with the surrounding air and are perceived as airborne sound. Transient flow and the pressure fluctuations associated with it produce this effect.

How to troubleshoot pump noise and vibration [ Part 1 ]?

Often when troubleshooting a system, many people only consider the obvious choice. Common occurrence and experience sometimes blind teams to other possibilities and may lead to time and resources spent solving the wrong problem. Part 1 of this article explores a situation in which the “obvious choice” for the source of pump noise did not add up.

Why does a multistage pump make noise?

Multistage pumps with balancing devices also produce substantial turbulence noise (see Fluid mechanics ), resulting from the characteristically high delivery heads of the individual stages, as can higher pressures when they are relieved in balancing devices, for example.

What kind of sound does a centrifugal pump make?

Statistical analyses have revealed that, depending on the type of pump and in non-cavitating operation, 10-9 to 10-6 of a centrifugal pump’s power input is converted to sound power, which may take the form of solid-borne, air-borne and liquid-borne sound.

What causes excessive noise in an electric motor?

Motor shaft end play Excessive electric motor noise can be caused by excessive motor shaft end play – the distance the shaft can move in and out of the motor. Beckett (1989) [1] notes that a new electric AC motor will have no more than .035″ of movement in and out.

Why is my pump making so much noise?

Initial indications revealed that the pump noise and vibration on the pump suction was not, in fact, because of cavitation. However, the simulation also calculated a system flow rate much greater than the intended design flow of the system.

Is there a cure for an electric motor noise?

Electric motor motor noise diagnosis: this article describes the causes, diagnosis, cure & prevention of noises traced to the electric motor component of an oil burner, air conditioner, or other electric-motor driven equipment.
