KRVS liquid ring vacuum units with partial or total liquid recirculation for the most demanding applications in the chemical, petrochemical, pharmaceutical and textile industries. Selected technical parameters: • Vacuum up to 33 mbar (a) • Pressure up to 2000 mbar (g) • Capacity up to 4200 m³/h

KRVS type units are devices for generating vacuum in many industries, including: chemical, petrochemical, pharmaceutical and textile.

The KRVS type / P units (with partial recirculation of the working liquid), apart from the RVS type vacuum pump, include a separation tank for the separation of working liquid and gas, as well as a set of connections and valves. In the case of KRVS type / T units (with total recirculation), the system is additionally equipped with a heat exchanger.

The main advantages of KRVS systems are:

  • reduction of noise and vibrations,
  • separation of the service liquid from the pumped gas,
  • no contact of the coolant with the pump,
  • simple installation, commissioning, adjustment and operation.

In KRVS 7-21 units, the tank is also the supporting frame for the vacuum pump; on KRVS 23-60 units, the free-standing separation vessel is located next to the pump on the same support frame.

The working liquid is cooled by a heat exchanger (only in the / T version) ensuring no contact between the cooling liquid and the working liquid, so that there is no possible contamination of the cooling liquid. The temperature of the working liquid is controlled by regulating the flow of the coolant.
