PERISTALTIC PUMP UPGRADE DELIVERS SAVINGS

Pumping sandpaper grit – aluminium oxide – can be challenging for some pumps due to it being highly abrasive.

Recently, CDR Pumps’ engineering team upgraded a customer’s peristaltic pump as its existing solution wasn’t reliable and was regularly failing.

The existing pump had a fixed shoe design with high levels of friction which reduced the life span of the peristaltic hose pump. Extra friction plus an abrasive material leads to more heat and extra wear and tear on the pump parts, neither of which are good for the long-term lifespan of a pump.

With aluminium oxide, a peristaltic pump is the only real choice. However, to overcome the issues present, the new replacement pump features a roller shoe design, silicon lubrication and the ability to change the ‘pinch’ level of the roller. This new solution has delivered savings on replacement parts, lower maintenance costs and less downtime.

In addition, the pump’s control system was re-engineered so the pump could be run in reverse to clear any blockages.

Having been in situ for almost a year without any problems, this solution has already proved itself to be more reliable than the original pump.

Peristaltic pumps are a great choice for slurries, sludges and highly viscous fluids – commonly able to handle between 15% and 80% solids (depending on the solution) – without issue. The solution doesn’t make contact with the moving parts of the pump, there’s no need for the pump to be primed with a service liquid, and dry-running is not a problem either.
