Liquid ring vacuum pump MZT PUMPI AD

Technical data:
Capacity up to 1000(m3/h)
Vacuum up to 730 (mmHg)

Design:
Liquid ring vacuum pumps CEL (single stage) and CEH (two-double) are rotary pumps, with star type impeller eccentrically placed in the cylindrical body.
The principle of operation is based upon the rotation of the impeller eccentrically placed in the cylindrical body, so that the auxiliary liquid forms “water ring”. During the rotation, a part of the water ring enters and emerges among the blades of the impeller so discharging (sucking part) of the operating gas (air), forms appropriate vacuum. The direction of rotation is signed with an arrow on the pump itself.
Except the impeller, the pump has no other movable parts, so that there is no need of any additional lubrication (except bearings) and the sealing between the impeller and the side plates is realizes with the auxiliary liquid.
The water ring also absorbs the whole water vapor that enters with the working gas, thus absorbing the impurities and taking off the heat of the gas.
The service liquid is usually water with optimal working temperature of +150C (max. 450C).
CEL - single-stage pumps with maximum vacuum of 610 (mmHg) can be used in
CEH – double-stage pumps with maximum vacuum of 735 (mmHg)

Applications:
- Paper and cellulose industry,
- Milking sets
- Absorption of vapors in ironing units
- Filter purification
- Humidity absorption of the fabric in textile industry,
- formation and maintenance of the vacuum in the vacuum plants,
- in chemical and pharmaceutical industry,
- in food industry,
- desalination plants,
- in impregnating equipment,
