Eliminate Leaks With Our Magnetically Coupled Screw Pumps
Are you sick of the mechanical seals on your pump wearing and causing leaks? Magnetic drive pumps may be your answer! The key design feature of magnetic drive screw pumps is that they do not have a mechanical seal, and instead use magnets to couple the pump head to the motor. This eliminates the chances of leakages caused by the mechanical seal wearing over time, making it a cleaner solution, ideal for pumping chemicals and aggressive fluids that can be potentially dangerous if leaked. Magnetically coupled screw pumps in particular tend to be used for flammable environments where medium viscosity oils, lubricants and fuels are pumped at high pressures thanks to their ability to handle lubricating fluids so efficiently. If you have an application that you think would benefit from a magnetic drive screw pump over a mechanical seal solution, then contact our pump experts for advice selecting the mag drive pump for your application.

FAQs
Triple screw pumps consist of a driving screw and two idler screws. The motor shaft rotates the driving screw which in turns rotates the intermeshing twin idler screws that the fluid passes along.
Screw pumps are ideal for handling fuels, oils and lubricants, thanks to their ability to maintain efficiency regardless of fluctuations in viscosity. As lubricating fluids' viscosities are susceptible to change as their temperature changes, the performance of a screw pump is able to remain consistent.
When it comes to fuel and oils, gear pumps are a more known technology, when infact screw pumps have a lot of benefits. They have a smaller footprint in comparison, provide a less turbulent smoother flow, less noise and vibrations and better mechanical efficiency.

Unlike other positive displacement pumps, screw pumps cannot handle solids so waste oils are usually avoided unless used with a strainer/filter.
Yes upon request. Being able to operate in both directions makes these screw pumps ideal for tank to tank transfer as well as returning excess liquid out of the pipework when transfer is complete.
Yes! All Azcue triple screw pumps are marine type approved by classification societies including Lloyds, Bureau Veritas and ABS. They are also suitable for low sulphur fuel down to 0.1% in line with the 2020 Global Sulphur Cap.
Our Azcue screw pumps are available with optional magnetic coupling. The absence of a mechanical seal to couple the pump and motor eliminates the chance of leaks caused by wear, which is often desirable when the fuel being pumped is flammable.
Yes, screw pumps have excellent suction capabilities without need for a manual priming device.
