Case Studies


With both our knowledge and our pump range covering a multitude of applications, Castle Pumps have the pleasure of supplying customers in a wide variety of industries, all of which require different standards. To demonstrate our experience across a number of markets we have compiled several interesting case studies. 

Paint & Powder Coating Manufacturer - AODD Pump

Paint & Powder Coating Manufacturer - AODD Pump

We received an enquiry from an industrial paint manufacturer who needed a pump for their oil/solvent mixture. The fluid was being used to clean used containers, before returning to the tank and starting the cycle again. With a cost-saving process and reliability being key, we chose a Debem AODD Pump - known for it's reliable performance and low cost maintenance.

Fresh Water Pumping for Civil Engineering - Vertical Inline Pump

Fresh Water Pumping for Civil Engineering - Vertical Inline Pump

This customer required a high flow fresh water transfer pump which would be free from corrosion and therefore keep the water contaminant free. We selected a bronze pump which we knew would be able to handle this type of fluid without any complications. We also decided to couple the pump with an electric 4 pole motor running at 1450 RPM which would increase the lifespan of the pump and in time, reduce overall costs.

Heavy Grout Transfer for Drilling Specialist - Peristaltic Pump

Heavy Grout Transfer for Drilling Specialist - Peristaltic Pump

This customer needed to replace their current pump as it was not completely suitable for their application - lacking control features which meant supervision was required when start/stopping the pump. We provided them with a completely bespoke peristaltic pump specifically designed for their application. It had all the desired control features, allowing supervision-free operation and improving their productivity.

Fuel & Coal Dust Slurry for R&D - Progressive Cavity Pump

Fuel & Coal Dust Slurry for R&D - Progressive Cavity Pump

A new customer approached us that needed a pump for an abrasive slurry of fuel oil and coal dust. The pump needed a low flow rate and the ability to handle abrasive coal dust, whilst also needing to be controlled by a variable speed drive for testing purposes. We supplied a progressing cavity pump as its properties and capabilities were the best match for the requirements.

Castle Pumps are able to supply pumps for both marine and industrial applications, and pride themselves on supplying pumps that best match the customers requirements. This enquiry was for self priming sea water injection pumps but the customer requested that the material be stainless steel 316, rather than the recommended material of bronze. We were able to provide a suitable pump that matched the customers requirements and which came in the requested material of stainless steel.

Testing Rig for Pipeline Pig Manufacturer - Multistage Pump

Testing Rig for Pipeline Pig Manufacturer - Multistage Pump

This pipeline pig manufacturer was hiring diesel driven pumps every time outdoor testing was taking place, but found that the hired pumps were noisy and inaccurate. They therefore wanted to purchase their own pump which would produce 80 l/sec at 8-10 bar, which was capable of 3-10 minute cycles, 6-10 times a day, with a maximum current of 158 A.

Wax Dosing for Home Fragrance Manufacturer - Peristaltic Hose Pump

One of the UK's largest home fragrance manufacturers enquired about a pump for transferring wax at 60°C, which could do a number of batches within a set time frame. Due to prior experience, we knew which pump would be the best solution for their specific requirements and were able to supply an industrial peristaltic pump, that was low maintenance and relatively low cost.

Adhesive Transfer for Laminate Flooring Production - Gear Pump

Adhesive Transfer for Laminate Flooring Production - Gear Pump

A wood and laminate flooring company in the UK needed to gravity feed an adhesive from an IBC to a piece of machinery in their product line, in order to apply the solution in a particular way to their products. One of the main factors we had to consider was the thickness of the fluid - with a viscosity of 4000-5000 cP, we selected a gear pump which we knew could handle this type of fluid. Furthermore, by selecting a gear pump we were also able to achieve the low flow rate that the customer required.

An existing customer contacted us with a new enquiry for a solids handling sea water pump, which needed to be less costly and have better lead times than existing pumps. We offered and supplied a non-clogging centrifugal pump with a vortex impeller, which can handle solids as large as the discharge diameter. Minimal modifications were needed to their existing system and lead time and price were improved greatly.
