The First Step To Reliable Pump Operation

Correct Installation

As seen in this photo; correct pump installation is typically neglected! The quality of this pump and driver installation will have a major affect on the performance and reliability of the pump, especially if it is equipped with a mechanical seal.

All too often problems with pump and motor bearings, shaft breakage and difficulty in aligning units stem from the improper installation of the pumping equipment. Inadequate foundations, bent or twisted baseplates, and excessive pipe strain can all work together to make an otherwise simple installation an operational and maintenance headache for the life of the unit.

Improper pump installation can lead to premature failure and increased maintenance costs. Conversely, when they are correctly installed and given reasonable care and maintenance, your pumps will be capable of operating satisfactorily—and delivering for you­—for a long time.

Correct and complete installation practices can mean the difference between a pump that gives many years of trouble-free service and one that requires constant and repetitive maintenance.

Three particular areas must be satisfied to ensure that a pump will provide long and reliable operation within a system:

1. FOUNDATION

2. PIPING ARRANGEMENT

3. ALIGNMENT

In general, a pump should be mounted on a strong baseplate supported by a strong concrete foundation. It is also necessary to properly connect the pump to the system by accurately aligning it to the piping system, as well as the driving motor. A strong foundation and grouting can result in a unit that gives reliable, uninterrupted service versus one that requires constant realignment. It should be everyone’s concern that only the best materials—together with proper design—be used when installing the pump

This is the single most abused area of pump installation. In fact, it can be stated unequivocally that most pumps are piped up incorrectly.

The location of the pump relative to its suction source is critical to its ultimate reliability. Every pump needs to be located as close to its suction source as possible to reduce the effect of friction losses on the NPSH available. However, it must also be far enough away from the suction source to ensure that correct piping practices can be followed

Industry has progressed well beyond any discussion of the statement that good alignment is essential to safe and trouble-free operation of rotating equipment. Alignment is achieved when two lines that are superimposed on each other form a single line. Misalignment is a measure of how far apart the two lines are from forming that single line. The two lines we are concerned with here are the centerlines of the pump shaft and the driver shaft.
