Triple screw pumps for fuels & oils

Castle Pumps have been supplying screw pumps to the industrial and marine market for over 10 years. Able to handle fluctuating flow rate and pressure without losing efficiency, screw pumps are ideal for clean, lubricating fluids such as fuels, oils and lubricants. Our range of quality screw pumps includes twin screw pumps and triple screw pumps. Whilst gear pumps are suitable for many similar applications; screw pumps have better mechanical efficiency, operate with less noise and fewer vibrations and providing less turbulence and a smoother flow. Read our comparison guide here if you need more information.

If you’re searching for efficient and reliable pumps for transferring clean fuels or oils, screw pumps are the perfect solution for you. Talk to our technical sales engineers to help you select the right screw pump for your application.

Screw Pumps vs Gear Pumps

When it comes to transferring fuels, oils, and other lubricating fluid, screw pumps and gears are usually the preferable choices. But what are the differences and advantages of these pump technologies? Whilst a gear pump is more than an acceptable option for the handling of lubricating fluids, the design of the screw pump has several advantages over it. Some of the key benefits that screw pumps have are smoother, lower vibration pumping, better suction capabilities, smaller footprint and better mechanical efficiency. 

To make these features as clear as possible, we have constructed a comparison table and detailed guide where you can find all the difference between these two pumping solutions.

Past Screw Pump Project

Using our extensive knowledge and expertise, we’ve helped hundreds of clients find the right triple screw pump for their fuel and lubricant applications.

Read our case study and find how we helped one of our clients, a UK ferry operator, who needed a Lloyds approved marine gas oil pump in 3-4 weeks to meet the vessels dry docking program where a fuel system conversion was being undertaken. With reliability and short lead-time being key, we specify and supply vertical inline screw pump in just over 3 weeks, complete with marine certification.
