Liquid Ring Pumps from 30- 435 m3/hr & 33-150 mbar (depending on version).

Dolphin LU
0080 - 0450 A and LH 0020 - 1600 A are a series of sophisticated, single-stage (LU) and double-stage (LH) liquid ring vacuum pumps in base plate version. The proven compression principle allows them to be used in all industrial sectors. Even critical applications such as evacuating saturated gases and vapours are possible without problems.

Application Oriented
Dolphin vacuum pumps are designed for continuous operation. The various designs and accessories allow the pumps to be easily adaptable for any process.

Well Proven
In the base plate version the modular design allows various assemblies to suit many applications.

Anti-cavitation Protection
We recommend the use of a vacuum relief valve or an AquaMin separator to protect the pump from the destroying effects of cavitation.

Heat Exchanger
For use in closed loop operating liquid circuits.

Gas Ejector
In combination with a liquid ring vacuum pump, the ejector enables the system to reach a deeper vacuum, down to 8 hPa (mbar).

Non-return Valves
Used to prevent the back-flow of the operating medium into the process when the vacuum pump stops.

Drain Valves
Simple and efficient accessories to protect the pump against overfilling with operating medium.

Vacuum Relief Valves
Control the operating pressure and protect against the negative effects of cavitation. Accessories are manufactured in various sizes and different materials so that adaptation to any process is possible.

As well as our standard products, we also offer individual solutions, from a single vacuum pump up to complete vacuum systems.
