2BEC series water ring vacuum pump

The characteristics：

These series products adopt single stage and single action structure and have many advantages, such as, compact structure, convenient maintenance, reliable running, high efficiency and economic power. Comparing with the SKC, 2SKC, SZ series water ring vacuum pumps used widely in our country at present, the 2BE series products are the ideal replacements of them for high vacuum, low power, and running reliability.

The main characteristics of 2BEC series products：

The tolerance, corrosive status, and the begrime situation can be easily observed by the big inspection port on both sides of the end-shield.

The 2BEC series pumps have flanges both on the top and sides with the same diameter. It is more convenient to connect with the 2BEC series pumps.
The bearings are all used of the imported products in order to keep the precise orientation and the high stability during the working of the pump.
The casing is made of steel or stainless steel plates to extend the lifetime of the 2BEC series pumps.
The shaft bushing is made of stainless steel plates to extend the life of the pumps 5 times more than the normal material.
The V-belt pulley (when the pump is driven by the belt) is used of the high precise pulley with taper bushing to keep the reliability of the pump and extend its life. And it is also easy to mantle and dismantle.
The unique design of setting the separator above the pump saves the space and decreases the noise efficiently.
All the spare parts are cast by the resin sands that make the surface of the pump very smooth. So it is not necessary to cover the surface of the pump with putty and gives out the heat efficiently.

Notes：
The installation dimension of the pump driven by the gear box is confirmed by the supplier of the gear box.

The data of the suction capacity in the above table indicates the maximum of the suction capacity. The practical data is various for the different suction pressure.

The optional speeds for 2BEC 400/420 pumps driven with V-belt: 327/349/393/446/475/498/527rpm.
