2BV Drinking water ring vacuum pump



2BV sequence water ring vacuum pump is suited for pumping& removing gas and water vapor. The suction pressure can achieve 33mbar absolute force (ninety seven% vacuum). When the drinking water ring vacuum pump is doing work for a prolonged time under the suction pressure close to the limit vacuum (saturated vapor stress of the operating fluid), the cavitation security tube ought to be related to shield the pump. When employed as a compressor, the optimum force is .26 MPa (absolute force).


2BV sequence drinking water ring vacuum pumps/compressors are mainly used to pump& take away flammable and explosive gases and work in different flammable and explosive environments.


Major attributes

one.The immediate link design and style of the motor saves area, effortless set up and hassle-free servicing.

two.The casting adopts precision casting technologies and is strictly developed in accordance with nationwide specifications. Neat appearance, good heat dissipation and excellent mechanical properties.

3. All have cavitation safety pipe interfaces. If functioning beneath intense strain, opening the cavitation defense pipe interface (or connecting with the separator) can eliminate cavitation sound and protect the pump although guaranteeing the maximum suction impact .

four. The 2BV sequence is geared up with stainless steel impellers, and the 2BV2 sequence is geared up with stainless steel discs and impellers. Large energy, sturdy and improve the corrosion resistance of the pump. If all the stream via components are manufactured of stainless steel, they can perform in more severe environments.

5. Distinctive flexible exhaust port design, no over-compression, ensuring the 2BV sequence has the best effectiveness in its overall performance selection.

6.YE2 collection large-performance motors are utilized, with security course IP54, IP55 (frequently IP44), and insulation class F course (common class B insulation)

seven.2BV sequence h2o ring vacuum pump can realize that all the flexible seals are polytetrafluoroethylene, which can tremendously extend the service life of the vacuum pump beneath severe functioning situations.

SK (2YK) collection water ring vacuum pump



SK, 2YK kind h2o ring vacuum pump is single phase double action, radial consumption and exhaust drinking water ring vacuum pump. The SK/2YK type h2o ring vacuum pump is usually employed to pump gas free of charge of sound particles, insoluble or somewhat soluble in water. Simply because the gasoline is near to isothermal compression throughout the functioning procedure of the water ring pump, it is also especially appropriate for suction and shipping and delivery of inflammable and explosive gases. The pump normally uses water as the working fluid.


one.One phase double action, radial intake and exhaust, substantial performance and power conserving.
two.The framework is durable, sturdy, lengthy existence, and can operate repeatedly for a prolonged time.
three.No direct mechanical friction, impeller and pump entire body is not contacted, no use.
4.There is an proper hole in between impeller and distributor, which is not sensitive to dust and particulates.
five.The foot is in the pump human body, mounted horizontally and dismantled, convenient for set up and upkeep.
six.All varieties of requirements are geared up with corresponding atmospheric ejectors to increase suction vacuum.

2BE1 water ring vacuum pump



The 2BE1 collection is a one stage solitary performing h2o ring vacuum pump with wide suction range. 



one.Solitary stage one action, axial ingestion and exhaust, basic composition, easy upkeep.

two.The exhaust equipped with versatile valve plate can instantly change the exhaust angle, enabling the pump to run effectively under diverse inhalation situations.

three.Geared up with computerized drain valve to handle the starting up degree of pump and steer clear of overload beginning.

four.The impeller end encounter is made 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 massive measurement impeller to avoid impurity retention, and enhanced the affect of structure on pump. The extracted gasoline is permitted to have non granular dust.

5.The packing cover is divided into half composition, which can be taken out as a complete, and the filling is more hassle-free to replace.

6.By altering the assembling angle of the sealing member, the operate of the internal circulation or exterior source of the cooling water can be recognized to satisfy the demands of distinct shaft seals. By connecting the leakage hole of the stuffing box, the dripping coolant can be introduced to the designated place to satisfy the specifications of environmental security. Little dimensions pumps have two types of shaft seals, packing and mechanical seals.

seven.The rotor with impeller diameter greater than 200 is outfitted with a sheathed shaft in the shaft seal position.

8.The axial and radial hundreds of the pump are independently borne by two distinct bearings. After enhancing the bearing composition, it can make certain lengthy-phrase and reputable procedure of the pump.

9.When the heat exchanger is installed, the functioning fluid can be recycled and the water use can be reduced. By means of the self suction capacity of the vacuum pump, the cooling operating fluid is sucked into the pump without added pressurization system.
