High Viscosity Pumps

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

Viscous fluid pumps for thick slurries, oils, waste and food

The nature of high viscosity liquids can vary a lot from heavy fuel oils to solid laden sludges to paste-like adhesives and food products. For this reason, over the last 15 years, we have built a large offering of quality constructed viscous fluid pumps that includes a range of different pumping technologies to meet different application needs. Certain pump types such as centrifugal pumps struggle with thicker fluids due to frictional losses inside the pump causing flow rates to rapidly decline, whereas high viscosity pumps excel under such conditions. Specifying your solution is where Castle Pumps can help….

Past High Viscosity Pump Project

For over 15 years Castle Pumps have been specifying high viscosity pumps, helping customers with solutions to move their thick fluids efficiently.

In this case study, find out how we helped a groundworks contractor to transfer heavy grout with little moisture with one of our peristaltic pumps that has no moving parts to clog. By supplying the pump with bespoke control features, we managed to improve their productivity by 35-40%!

Why Viscosity is Critical to Pump Selection

When specifying a pump for high viscosity fluids, we'll need to check what type of fluid you'll be pumping. Viscosity is critical for pump selection, and with so many different types of viscous fluids, it's no surprise that the range of viscosity can vary. Confirming the viscosity of the pumped medium will put you on track to getting the right pump for your application.
