GEMMECOTTI liquid ring vacuum pumps types VPM,VPS, and VPL, are constructed in a conventional overhung impeller design. They are suitable for operating with both toxic ad dangerous gases.
GEMMECOTTI liquid ring vacuum pumps attain high levels of vacuum by means of isothermal compression. They can evacuate most gases and vapors and are especially suitable for the evacuation of gases containing both condensate and liquid compositions for arduous applications.
GEMMECOTTI liquid ring vacuum pumps generally operate without contact between internal rotating parts, with the exception of the mechanical seal rings for pumps VPS and VPL and the rotating bushes for pump VPM (magnetic drive). Due to their inherent design, contact is required, however, the service liquid ensures that both the mechanical seal and bushes are lubricated sufficiently in these designs.
VPM, VPS, and VPL models are also capable of operating without the need for an external lubrication source, as the standard design uses sealed for life bearings.
Vibration and noise levels are minimized and fall well below industry requirements on all models within the range. VPM, VPS and VPL have the capability to incorporate automatic drain and anti-cavitation valves.

VPM, VPS and VPL liquid ring vacuum pumps structure:
VPM range: Sealless pump, magnetic drive. Support
is guaranteed by standard design of silicon carbide slide bearing.
VPS range: available in close coupled design and fitted with single mechanical seal. Supported by means of standard bearings fitted to the electric motor.
VPL range: Standard execution with single mechanical seal. For more arduous duties it is also possible to install a double mechanical seal with an external flushing system. Support by a robust bearing bracket complete with sealed for life ball bearings. GemmeCotti can also install an oil lubricated ball bearing design for this construction if requested.
