Reconditioning to your Rescue – Improve your Pump Efficiency & Make it Last Long

Though industrial pumps don’t undergo immense wear and tear, their performance takes a dip after a few years of usage. Worry not, Sintech Pumps provides reconditioning solutions to your rescue. Why Reconditioning? It can help your pumps last longer than their average life cycle. Also, reconditioning is highly environmentally friendly, as you don’t replace pumps but instead give them a new lease of life. Furthermore, the costs of reconditioning are significantly lower than the cost of a new pump. With reconditioning, you can restore the reduced capacity of your pump to its original level. Here’s a Bullet-point List of the Benefits of Reconditioning:

  • Your pump is restored to its original efficiency and capacity
  • All types of pumps can be reconditioned
  • No further modifications required to the foundations and piping
  • Lower cost
  • Eco-friendly
Is it time for a Pump Recondition? Here are the factors you have to consider before you decide to recondition your pump.
  1. System Requirements
Has your pump’s performance deteriorated to the point that it no longer meets the head and flow requirements? If yes, then your pump must either be replaced or reconditioned.
  1. Pump Deterioration Levels
Once you have determined that the pump’s performance has deteriorated, the next step is to find out by how much? In order to find this, you have to conduct a detailed pump system analysis, to help you find out the true performance degradation.
  1. What causes the pump’s performance deterioration?
Is the pump deterioration caused by the following elements?
  • Wearing ring clearance
  • Roughening of the pump’s waterways
  • The speed of the pump’s operation. Higher the speed, the greater is the impact or friction caused. (with higher speed, the flow is increased, while the head is reduced)
  • The magnitude of the water passages. Larger pumps can allow greater amount of roughness, while smaller pumps see a reduction in efficiency, with higher roughness.
  • Or other reasons
Answering the big question, Should the Pump be Reconditioned? Once you have determined the levels of pump performance degradation, the energy saving potential, the impact of the losses incurred due to internal leakage and increased friction, the cost of reconditioning, and the payback as a result of reconditioning – have to be charted to decide whether you should go in for a recondition or replacement of the pump. What are the Common Methods Employed for Reconditioning Pumps:
  1. Waterways
There are several aftermarket ways to recondition pump casings, impellers, and internal passages. Some of the most common techniques used are sand/grit blasting, wire brushing and coating.
  1. Wear Ring Clearances
Another easy way to recondition pumps is to replace wearing rings. This helps to not only improve the head and efficiency of the pump, but also reduces NPSH, since the turbulence and flow through the eye of the impeller is reduced. The lower the pump’s speed, higher is the impact of the wearing ring clearance on the pump’s overall performance. Where to Recondition Existing Pumps? If your pump is in need of reconditioning, make sure to approach your pump’s manufacturer who can accurately determine whether your pump’s efficiency can be improved with reconditioning or whether you have to replace the entire unit to improve the efficiency of the system.
