Enquiry

Castle Pumps were contacted by a University with a requirement for a pump to transfer a concentrated saline solution to a header tank that was situated 12 metres above the pump. The flow rate performance required was very low at only 100 l/hr, which limited the amount of pumps suitable.

Solution

The required flow rate of 100 l/hr indicated to us that a peristaltic pump would be most suitable for this application. The slow operating speed and smooth non-pulsating pumping action of the peristaltic pump allows very low flow rates to be achieved. We selected a peristaltic pump coupled to a 0.25Kw motor complete with gear reducer; the gear reducer allows the pump to operate at a speed of only 46 RPM.

Peristaltic pumps only have a few wearing parts meaning that spare part requirements are very low. The only component that comes into contact with the fluid is the hose, which permits the selection of lower cost casing materials that are not compatible with salt solutions.
