pump shaft seal How to Know If a Pool Pump Has Gone Bad
In a typical residential pool, the pump must cycle 90,000 gallons of water per day.The suction generated by the pump takes water at the water level and the main drain at the bottom of the pool through the pool apostrophe.This water is pumped through the filter under positive pressure and is delivered back to the pool through the return line.For proper hygiene, the pump should filter the entire volume of the pool every 8 to 10 hours.The wear in the pump impeller is usually manifested as a low reading on the filter pressure gauge.Depending on the output of the pump and the type of filter, the appropriate pressure reading will vary.However, the filtration pressure of most systems is within the range of 15 pounds per square inch.For other reasons, such as a clogged skimming basket or a pump filter, it is not possible to explain the continuous lower reading, which may indicate that the pump impeller is worn out too much.When the pump is running, water spraying from the pump shell under pressure usually indicates a simple pump Shell O-ring leak.However, even if the pump is not running, the water will be continuously transported from the bottom of the pump, forming a continuous puddle on the sink equipment pad, usually a sign of wear and tear of the main motor shaft seal of the pump.
