2BV Water ring vacuum pump

2BV series water ring vacuum pump is suitable for pumping& removing gas and water vapor. The suction pressure can reach 33mbar absolute pressure (97% vacuum). When the water ring vacuum pump is working for a long time under the suction pressure close to the limit vacuum (saturated vapor pressure of the working fluid), the cavitation protection tube should be connected to protect the pump. When used as a compressor, the maximum pressure is 0.26 MPa (absolute pressure).

2BV series water ring vacuum pumps/compressors are mainly used to pump& remove flammable and explosive gases and work in various flammable and explosive environments.

SK (2YK) series water ring vacuum pump

SK, 2YK type water ring vacuum pump is single stage double action, radial intake and exhaust water ring vacuum pump. The SK/2YK type water ring vacuum pump is usually used to pump gas free of solid particles, insoluble or slightly soluble in water. Because the gas is close to isothermal compression during the working process of the water ring pump, it is also especially suitable for suction and delivery of inflammable and explosive gases. The pump usually uses water as the working fluid.

Features
1.Single stage double action, radial intake and exhaust, high efficiency and energy saving.
2.The structure is sturdy, durable, long life, and can run continuously for a long time.
3.No direct mechanical friction, impeller and pump body is not contacted, no wear.
4.There is an appropriate gap between impeller and distributor, which is not sensitive to dust and particulates.
5.The foot is in the pump body, installed horizontally and dismantled, convenient for installation and maintenance.
6.All kinds of specifications are equipped with corresponding atmospheric ejectors to increase suction vacuum.

2BE1 water ring vacuum pump

The 2BE1 series is a single stage single acting water ring vacuum pump with wide suction range. 

Features

1.Single stage single action, axial intake and exhaust, simple structure, easy maintenance.

2.The exhaust equipped with flexible valve plate can automatically adjust the exhaust angle, enabling the pump to run efficiently under different inhalation conditions.

3.Equipped with automatic drain valve to control the starting level of pump and avoid overload starting.

4.The impeller end face is designed by classification, which reduces the sensitivity of the pump to the dust and water scaling in the medium. Improved the structure of impeller reinforcing ring of large size impeller to prevent impurity retention, and improved the influence of structure on pump. The extracted gas is allowed to have non granular dust.

5.The packing cover is divided into half structure, which can be removed as a whole, and the filling is more convenient to replace.

6.By adjusting the assembling angle of the sealing member, the function of the inner circulation or external supply of the cooling water can be realized to meet the needs of different shaft seals. By connecting the leakage hole of the stuffing box, the dripping coolant can be brought to the designated place to meet the requirements of environmental protection. Small size pumps have two types of shaft seals, packing and mechanical seals.

7.The rotor with impeller diameter larger than 200 is equipped with a sheathed shaft in the shaft seal position.

8.The axial and radial loads of the pump are separately borne by two different bearings. After improving the bearing structure, it can ensure long-term and reliable operation of the pump.

9.When the heat exchanger is installed, the working fluid can be recycled and the water consumption can be reduced. Through the self suction ability of the vacuum pump, the cooling working fluid is sucked into the pump without additional pressurization device.

10.2BE1 101~253 water ring vacuum pump. Pump body and side cover are connected by pull rod. 2BE1 303~705 water ring vacuum pump, flange connection between pump body and side cover ensures the overall rigidity and vibration resistance of large size water ring vacuum pump. When the maintenance space is small, horizontal installation can be used.

11.Using ordinary materials can meet the general requirements.

12.When the flow through parts are manufactured with different grades of stainless steel, they can meet different anticorrosion requirements.

13.When the flow through parts spray special materials, the anticorrosion cost of large size water ring vacuum pumps can be reduced. Its smooth surface can also effectively reduce the precipitation of ash like substances and slow down the scaling process.

14.When the inner cavity of the pump body is lined with vulcanized rubber, the corrosion resistance of the pump body can be improved.

15.2BE1***-0, the suction range is wide. The low suction pressure can reach 33mbar (abs), and with the first level ejector, the suction pressure can be lower than 33mbar (abs).

16.2BE1***-1, low suction pressure can reach 140mbar (abs), and the recommended range of effective suction is 160~1013mbar (abs).

17.When the water ring vacuum pump is supported with the anti cavitation device, it can effectively improve the operation of the pump in a high vacuum.
