Edwards Vacuum Boosters

Experience the perfect balance of speed, reliability, and efficiency. Whether you are managing aggressive chemical reactions or high-volume industrial manufacturing, Edwards’s comprehensive range of booster pumps is engineered to deliver consistent output and maximum up time.

Engineered for high differential pressures and featuring the unique Hydro kinetic drive, the EH Series allows the booster to start simultaneously with the backing pump. Significantly reduced total pump-down times and simplified system control.

The HV8000 is the workhorse of large-scale industrial applications. Delivering a nominal pumping speed of 8,640 m³/h (5089 CFM).

When your process demands durability and consistent uptime, the Stokes 6” Series mechanical booster delivers. Built on a legacy of engineering excellence, this booster pump combines a rugged, heavy-duty design with the "workhorse" reliability that Stokes is known for globally. Available with an optional bypass valve, allowing for integrated operation starting from atmospheric pressure.

The GMB Series redefined the standard for Roots vacuum boosters. Engineered specifically for the most demanding applications, the GMB combines a patented, high-strength construction with a compact footprint to deliver maximum displacement and ultimate system flexibility.
