    We use latest design technology to design the pump, use advanced three-dimension design software UG to design the structure and use fluid calculation and analysis technology CFD to make the pump run reliably and efficiently with long lifetime.

    We provide the best model selection plan. For different users, we use different solution.

    The pump has best operating efficiency. The flexible air relief valve designed according to the venting features of liquid ring vacuum pump can adjust the venting air automatically according to changes of the pressure at suction so as to avoid overcompression which may cause unnecessary waste. In this way, the operating efficiency of the pump is improved and makes the pump run at the most efficient point in complete vacuum scope.

    The pump is very safe. Because there is not any metal contacts inside the pump and the liquid film formed inside the pump has a complete sealing result and can prevent leaking, which makes the liquid ring pump very suitable for pumping or compressing flammable, explosive and erosive gas.

    The pump is very steady during operation. The rotators are done dynamic balancing of high precise grade and the axial diameter of rotators are very enough which ensures the pump run steadily without vibration. There is no impulse and vibration at pumping and compressing. The flexible air relief valve avoids overcompression and noise. The pump runs very steadily with low noise and is easy to maintain and repair.

    A large window is set at the sucking side and discharging side of the cover and through the window, the maintaining person can check the clearance between the impeller and the round plate, erosive condition and water scaling condition.

    The pump pulley and the electrical pulley is connected with the shaft with tapered sleeve. It's very convenient for disassembling and maintaining.

    The pump is very reliable. The imported bearings of different specifications are used for the pumps of different sizes and the lifetime of the bearings are over 20 years.

    According to the user's requirement to the temperature rise, we measure the temperature with platinum resistance thermometer and measure the temperature of the bearing on line. We can also check the vibration.

    The pump can reduce the working liquid consumption in large volume. The working liquid of SLV liquid ring vacuum pump is self-priming type. The pump sucks suitable amount of water automatically from the container according to the sucking pressure and it's unnecessary to be controlled by people, which simplifies the operation greatly. Because closed circulating system is used and it reduces the consumption of working liquid greatly and the draining of the waste liquid, the cost is cut greatly for the users.

    The pump is easy to install. In order to install conveniently, the pump is set vent on top and face side. The inlet and outlet flange pressure grade is 1.0MPa. When using the top vent flange, top-mounted air-water separator can be used to save much floor area. When it's necessary to save investment, side face vent flange can be used. Both of the two ways won't affect the performance of the pump.
