Mechanical Booster Pumps
Mechanical booster vacuum pumps are positive displacement pumps which use rotors or lobes to increase pressure differentials and boost the performance of a backing pump. This type of pump is best suited for industrial applications with high flow rates or varying pressures. These pumps operate without any oil, because of which they are widely used in industrial applications that require a clean and oil-free vacuum environment.
Mechanical booster vacuum pumps are positive displacement pumps which use rotors or lobes to increase pressure differentials and boost the performance of a backing pump.
Explore our top-performing range of Mechanical Booster Pumps, including: EH Mechanical Booster Pumps, Stokes Booster Pumps, HV Mechanical Booster Pumps and GMB40K High-Capacity Roots Vacuum Booster Pumps.
Our pumps are engineered for stability, ensuring a consistent output, making them ideal for continuous operation across a wide range of pressures.
One of the key advantages of our mechanical booster pumps is their large installed base, indicating their reliability and proven performance. Additionally, we offer ATEX options for applications in hazardous or chemical environments, providing enhanced safety and efficiency.
Experience seamless operations and dependable results with our Mechanical Booster Pumps. Choose Edwards for your industrial and chemical pumping needs and ensure reliable performance in every application.
EH Mechanical Booster
The EH range is ideal for use with high differential pressures, allowing the booster pump to be started at the same time as the backing pump, reducing your total pump down times and making your operations simpler.
Features and Benefits
- Pump-down times cut by up to 50%
- Robust operation even for harsh duties
- Automatic overload protection
- Simplicity with reduced installation costs
