Low Shear Pumps

Need some advice? Our technical sales engineers are always on hand!

Shear sensitive pumps for delicate and easily altered fluids

When it comes to the handling of shear sensitive liquids, it is important that a low shear pump is selected to prevent the fluid from being damaged or altered. Under force, delicate fluids can change viscosity like cream being whipped, or their solids can be crushed, like fruit pieces in a yoghurt. Whilst certain pumping technologies such as centrifugal pumps apply high shear in operation, shear sensitive pump designs are able to keep such fluids intact due to their low internal velocity and the wider tolerances between their pump casing and internal components. Failing to select a low shear pump can result in product inconsistencies, damaged solids and costly waste. If you have a shear sensitive application, then Castle Pumps’ range of reliably operating solutions can help.

Past low shear pump project

Castle Pumps have been specifying quality, low shear pump solutions for over 15 years meaning that we have problem solved an application just like yours before.

In this case study, find out how we helped one of the largest home fragrance manufacturers in the UK with their requirement for dosing a thick, shear sensitive rapeseed wax on their production line. We specified a peristaltic pump capable of accurately delivering these small batches of wax without changing its consistency.
