    EH Roots Vacuum Pumps

    The EH series pumps are designed for high differential pressures, allowing simultaneous operation of the booster and backing pumps, reducing pump-down time and simplifying processes.

    Up to 50% faster evacuation

    With the patented hydrokinetic drive, the booster can operate at atmospheric pressure, cutting evacuation time by up to 50%. This drive system automatically slows the pump at higher pressures, preventing overheating.

    Reliable performance under tough conditions

    The robust shaft seal design protects the pump mechanism and gearbox from contamination, even in harsh environments. The EH pumps withstand sudden inlet pressure spikes, preventing unplanned downtime and improving overall efficiency.

    Automatic overload protection

    The variable speed function protects the motor from overload and overheating, ensuring longer operation. The hydrokinetic drive enables automatic adjustment to high-pressure differentials, making the EH series versatile and powerful.

    Cost-efficient and easy installation

    EH pumps eliminate the need for bypass lines, pressure switches, or inverters, reducing installation costs. The durable hydrokinetic drive ensures easy setup and low maintenance, making it a reliable solution for demanding applications.
