Under normal working conditions, the pump oil of Roots vacuum pump will only be loaded under the condition of natural wear of bearing and gear transmission. The EVP vacuum pump manufacturer recommends a secondary oil change after approximately 500 hours to remove any metal particles that may be g...

The impeller rotor of liquid ring vacuum pump rotates to produce water ring. It is a mechanical vacuum pump that the volume between the water ring and the blade changes periodically due to the eccentric rotation of the rotor. Reciprocating vacuum pump uses reciprocating motion of piston to pump a...

ISO vacuum calipers are used to connect small diameter isof threaded vacuum pipes. They are used in combination with ISO vacuum thread flange, ISO center bracket and ISO vacuum blind plate. It can also be used in combination with ISO vacuum valve, ISO vacuum bellows and ISO vacuum chamber. ISO va...

The stator of screw vacuum pump is an important part easy to be damaged in screw pump. The accuracy of stator tooth profile curve and material selection must be considered in the design and development, which directly determines the length of stator life. The selection of rubber material formula...
