Product Name:
DOLPHIN LG 0890/1200 A Liquid Ring Vacuum Pump

DOLPHIN are the robust liquid ring vacuum pumps and compressors from Busch. This series encompasses decades of experience in the use and further development of liquid ring technology.

Their proven operating principle provides virtually isothermal (cold) compression which is especially useful for sensitive or hazardous gases.

They are the perfect solution for demanding applications. For example, the evacuation of saturated gases and vapors.
The DOLPHIN series comprises a large variety of sizes and assemblies: single- or two-stage, with a directly flange-mounted motor, or assembled on a base plate, vacuum pumps and compressors.

DOLPHIN LG/LR is a series of high-capacity liquid ring vacuum pumps. They can be used in many industrial sectors, even for demanding applications. For example, the discharge of particle-laden gases or highly saturated vapors.

Their modular base plate design allows these vacuum pumps to be perfectly adapted to many different industrial processes.

Various assemblies and construction materials are possible, including cast iron (EN-GJL-200) and 316 grade stainless steel.

A wide variety of operating fluids can be used to perfectly match all process requirements.

Advantages:
1.Robust: Proven technology, reliable operation, extremely high vapor and particle tolerance, specially designed for challenging environments like mining, power plants, sugar production, pulp and paper industry, steel production etc.;

2.High performance: High-capacity, high pumping speeds;

3.Flexible:Modular design, choice of cast iron (EN-GJL-200) housing with ductile cast iron impeller or all 316 grade corrosion-free stainless steel material, operating fluids other than water possible, operation as compressor possible.
