Product Name:
DOLPHIN LB 0265–0425 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 LA/LB is our series of robust and reliable liquid ring vacuum pumps in base plate design. Their proven operating principle allows them to be used in many sectors of industry.

Even demanding applications, such as evacuating saturated gases and vapors are possible without problems. Different operating fluids may be used according to process conditions.

Thanks to the modular design, various assemblies are possible. The precisely dimensioned range of sizes, a wide variety of shaft sealing options, choice of accessories and construction materials allows you to find the perfect DOLPHIN LA/LB for your process.

DOLPHIN LA are single-stage vacuum pumps whereas DOLPHIN LB have two stages for a higher vacuum.

Advantages:
1.Robust: Proven technology, durable single-stage construction;

2.Reliable: Extremely high vapor and particle tolerance;

3.Flexible: Wide range of construction materials, including cast iron (EN-GJL-200), many grades of stainless steel and even titanium, ATEX-certified version available (Cat 1(i)/2(o) IIC T5), different operating fluids possible, operation as compressor possible.
