Water Ring Vacuum Pump
DLV Series Double Stages Water Ring Vacuum Pumps
DLV series two-stage water ring vacuum pump is our new design based on 2SK pumps and combines German double-stage pump design criteria. This series has two compression processes, with the 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.
As one of the water ring vacuum pump manufacturers, suppliers, and exporters of mechanical products, We offer water ring vacuum pumps and many other products. Please get in touch with us for details.

Advantages:
1. Wider range of suction pressure. Compared to other double-stage pumps (suction pressure 50mbar-150mbarA), the DLV pump works in 25mbar～1013mbar pressure, with less energy consumption, with15%-20% lower than traditional ones.
2. All kinds of models to fulfill various process requirements.
3. Materials are optional to make the pump possible to work in various harsh environments, Such as carbon steel, stainless steel, dual-phase steel, titanium, etc.
4. Single or double mechanical seal and several flush methods.
5. Precise casting, high standard accessories, imported bearing; high efficiency and energy saving.
