DLV series two stage liquid ring vacuum pump is our new design based on 2SK pumps and combines Germany double-stage pump design criteria. This series has two compression processes, with steady suction speed in high vacuum, or keeping the high vacuum in a wide range of suction speed. Its efficiency in high vacuum is 35%-40% higher than that of single stage pump, but with less energy consumption.
- Wider range of suction pressure. Compared to other double stage pumps (suction pressure 50mbar-150mbarA), DLV pump works in 25mbar~1013mbar pressure, with less energy consumption, with15%-20% lower than traditional ones.
- All kinds of models to fulfill various process requirements.
- Materials are optional to make the pump possible to work in various harsh environment, Such as carbon steel, stainless steel, dual-phase steel, titanium, etc .
- Scope of supply are optional, such as: pump head, pump with suction communicating pipe, separator and liquid pipes, pump aggregate with motor and base frame, complete set of closed cycle system with all auxiliary devices, the system with two or more stages when the inlet pressure is smaller than 33mbar (abs.).
- Single or double mechanical seal and several flush method.
- Precise casting, high standard accessories, imported bearing; high efficiency and energy saving.
