My neighbor installed the wrong type of capacitor on my Grundfos water pump motor. He installed a start capacitor with 30 mfd when he should have installed a run capacitor. Start capacitors which are intended to increase starting torque are designed for CSCR or CSIR motors. These systems will utilize a centrifugal switch, current relay, or potential relay to remove the capacitor from the circuit once the motor reaches ~75% of rated RPM. This usually will take less than 1 second. Start capacito

Pulley Ratio   For most people, the only alternator rating they are familiar with is the amperage rating.Alternators are spoken of as a 65 amp or 100 amp alternator. When replacing the alternator on the family car, this is probably the only information that is necessary. After all, all one needs is an alternator that matches the original. When building a custom car from the ground up however, a deeper understanding of the power curve of an alternator is required. Usually a custom

How to Determine Ratio and Rotor Speed The alternator rotor RPM is not necessarily the same as engine RPM. To calculate the actual alternator RPM, determine the ratio between the two pulley diameters. Ratio = Crankshaft Pulley Diameter/ Alternator Pulley Diameter Now that we know the ratio, we can now determine the rotor speed: Rotor RPM = Pulley Ratio x Engine Speed (example; 2.1 x 870 = 1827 Rotor RPM) Tech Tip: Generally, the alternator should be 1:1 with the motor for circle t

Bad or Wrong Breaker Sometimes breakers just fail due to age or inferior quality.  If the problem does not appear to be with your pump and/or motor, try replacing the breaker.You could also have the wrong size breaker if you recently bought a new pump or motor that was not an exact match to the previous model. Confirm you have the correct breaker size by checking how many amps the new motor requires. Defective Pump Motor You might be able spot an obvious pump motor short by disconnecting

Often times a pump will leak or spray water affluent to the intake after water has become pressurized. Usually this can be explained by cracked or deformed components, o-rings, or a bad mechanical shaft seal. When water is pouring out behind seal plate where the shaft enters the housing it indicates a worn mechanical shaft seal and is need of replacement. A common leak on a pool pump is the connection on the return side.The seal has to be replaced once in 03 years.  If not, it will leak

The pump is fully primed and there are no air leaks. The pump strainer either slowly fills with air or does not show sign of water movement at all. Well, there are two possible explanations. One is that the pump is cavitating or starved for water. There is either an obstruction in the suction line or the line is collapsed. Collapsed lines need to be re-plumbed and are usually associated with poly piping or flex line. If you suspect there might be an obstruction you may need to put pr
