DOLPHIN VL – The Complete Solution
Dolphin VL is the new generation of liquid ring vacuum pump units from Busch, based on the proven Dolphin LM/LT technology.
Dolphin VL units are available with either single (Dolphin LM) or two-stage (Dolphin LT) vacuum pumps for rough vacuum applications from atmospheric pressure to 130 hPa (mbar) or 33 hPa (mbar) ultimate pressure respectively. The Dolphin VL series is available in a total of thirteen sizes, allowing an exact match to every process.
The operating fluid is usually water, but other liquids may be used if required by the process conditions. Dolphin VL liquid ring vacuum pump units may be operated as a simple continuous flow system, or as a partial or total recirculation system.
The precisely dimensioned range of sizes, extensive range of accessories and choice of construction materials allow these vacuum pump units to be perfectly adapted to many different industrial processes.
Dolphin VL technology uses the proven liquid ring principle, with contact-free internal components and virtually isothermal compression.
The VL series has been developed for continuous operation to support a wide range of processes in many industrial sectors, including plastics, food and beverage, chemical and pharmaceutical industries.
