Pump piping plays the crucial role of providing a channel for the liquid to flow to and from the pump. It should do so without unfavourably affecting pump performance. Unfortunately, many pumps are installed incorrectly leading to premature failure.
Most pumps come with installation manuals, but this does not seem to help in reducing instances of improper piping arrangements. As you search for the best pump suppliers, you may also want to go through these four rules for better piping installations.
Avoid Elbows near Inlet Nozzle
Nothing is worse to the suction inlet than an elbow. An elbow will always produce uneven flow. Once this flow enters the pump impeller, air entrainment and turbulence may occur, leading to vibration or even impeller damage.
Minimise Size of Suction Piping
Poor suction designs are the cause of many pump problems experienced today. The suction piping should be kept as short as possible to ensure that the inlet pressure drop does not go too high. In the same vein, no obstruction should be in the line distancing up to 10 times the pipe’s diameter from the pump inlet.
Rid Suction Piping of Air Entrapment
Vapour or air in the pipework is another no-no. Some problems caused by air entrapment include vibration, loss of performance and pump damage. You can prevent such issues in the design by keeping fitting and piping connections airtight and maintaining adequate fluid levels in supply reservoirs.
Avoid Unnecessary Force on Pump
Many are times you find a pump that is the primary support for discharge or suction piping. While such a setting may appear harmless in the short term, any pressure or strain on the pump reduces performance and lifespan.
Pump suppliers may provide high-quality pumps, but it all counts for nought if design, installation and maintenance are wanting. Take care of your pump piping using these rules and the system will serve you for more years.
