Gas volume range: 145 - 2500 m³/h

The DLV series is particularly suitable for various industries such as food, chemical, pharmaceutical, power, papermaking, textile, metallurgy, etc., for processes such as vacuum drying, evaporation, distillation, concentration, filtration, dehydration and degassing.

From the curve in the above figure, it can be seen that the single-stage liquid ring vacuum pump is suitable for use in situations where the vacuum requirement is not high, and it has a large suction capacity. However, when working within a higher vacuum range, the suction capacity significantly decreases (it begins to sharply decline at less than 200 mbar, and the decline is severe at less than 100 mbar). In this condition, the efficiency of the vacuum pump is extremely low and the power consumption is very high. In contrast, the double-stage liquid ring vacuum pump can obtain a larger suction capacity within a higher vacuum range. In the high vacuum working state, its efficiency is 30% to 40% higher than that of the single-stage liquid ring pump, and the power consumption is correspondingly reduced. Therefore, the double-stage liquid ring pump is more suitable for situations that require a large suction capacity while maintaining a high vacuum level.

The DLV series double-stage liquid ring vacuum pump is a new type of double-stage liquid ring vacuum pump developed by our company based on the 2SK series. The DLV series liquid ring vacuum pump is designed with a two-stage compression process. It maintains a stable suction rate within a higher vacuum range, or maintains a high vacuum level within a larger suction rate range. In a higher vacuum working state, its efficiency is 35% to 40% higher than that of a single-stage liquid ring pump, and the energy consumption is also reduced accordingly.

A wider range of suction pressure, compared to the suction pressure of other two-stage pumps which is 50mbar - 150mbar A. The DLV series can operate within the range of 25mbar to 1013mbar; lower energy consumption, 15% - 20% more energy-efficient than traditional products. Various specifications to meet various process requirements. Multiple materials such as carbon steel, stainless steel, duplex steel, and titanium can be selected. Suitable for harsh application environments.

The supply range of pumps can be customized in various ways, such as: pump heads; complete pumps, including suction connecting pipes, steam-water separators and liquid piping components; vacuum pump units, including motors and bases; complete sets of units, including all auxiliary equipment required for the closed-loop system; secondary or multi-stage vacuum systems with single or double-end face mechanical seals for inlet pressures lower than 33 mbar (absolute pressure); multiple flushing schemes. Precision castings, high-standard accessories, imported bearings, high-efficiency energy-saving, quality assurance.
