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,

The DIP range of pumps was developed for operation in industrial systems. Excellent vacuum performance data combined with the inherent ruggedness of this kind of pump, make our DIP pumps a reliable component in high and medium vacuum applications.
Advantages to the User
High pumping speeds in the fine and high vacuum ranges
Low attainable ultimate pressure
Integrated, water-cooled cold cap baffle guarantees low oil backstreaming rates into the vacuum chamber
Low oil losses (even at high gas throughputs) by integrated, water-cooled forevacuum baffle
High forevacuum resistance even at reduced heating power
The heating cartridges are accessible from the outside via heating inserts which are built into the boiler. This ensures a quick exchange of single heating cartridges (even when the pump is hot)
A separate automatic circuit breaker for each heating cartridge ensures a high level of electrical safety
A standard built-in thermostat acts as an thermal overload switch and ensures that the heating cartridges can not overheat
All pumps are prepared for installation with an over-temperature switch (optional) for checking the cooling water circuit, and a contact thermometer (optional) to monitor the operating temperature of the diffusion pump
Indication of the oil level by sight-glass permits simple checking of the current oil level
All DIP pumps are delivered with their inside chamber cleaned in such a manner that it is free of oil. The inside is evacuated. In the condition as delivered, the pumps may be also operated with silicone oil
Typical Applications
The diffusion pumps from the DIP range are used in coating systems, vacuum melting and drying systems as well as in vacuum furnaces in the area of metallurgy

| Their special design with low weight and small dimensions make the UVD units extremely compact and reliable. This is achieved through the direct assembly of rotor on motor shaft and a powerful centrifugal fan for cooling. UVD vacuum pumps are suitable for evacuation of small, closed systems with residual pressure of up to 120 mbar. |

An elastomer diaphragm is moved up and down by an eccentric. On the down-stroke it draws the air or gas being handled through the inlet valve. On the up-stroke the diaphragm forces the medium through the exhaust valve and out of the head. The compression chamber is hermetically sealed from the drive mechanism by the diaphragm. The diaphragm pumps transfer, evacuate, and compress completely oil-free.

Simplicity of design with only one shaft and direct drive produces robust, long-lasting pressure/vacuum generators compressors with low maintenance and running costs. These pressure/vacuum generators operate completely oil-free; the individual chambers are separated by long-life vanes. Already featuring integrated intake filter and control valve, these pressure/vacuum generators can be fitted with other accessories without a problem. The blast air cooler, which is also integrated, guarantees a very low blast air temperature. The compact cover ensures low noise and heat emission. The combined pressure/vacuum generators are additionally equipped with a second intake. This provides the capability of making minor adjustments to the suction and pressure side as well as to high blast air volumes. By way of option, the second intake can also be used as a second low-vacuum suction air supply. Optional corrosion protection also makes these vacuum pumps suitable for extracting moist air.
