vacuum spool pump Avs-90 is designed to pump air, non-aggressive gases and steam-gas mixtures, pre-cleared from drip moisture and mechanical pollution Environmental temperatures from 10 ° C to 35 ° C., as well as to create pretext (100-200 MBAR) in high-convocation plants.
Vacuum pumps Avs-90 Single-stage parallel pumps. ">
Units consist of a pump, engine, and cuneiform transmission.
Materials for the performance of the running part of the pump are gray cast iron, or became ordinary brands. Pump shaft seal - cuff.
The pump and electric motor (together make up the AVZ unit) are mounted on a common foundation frame or plate; The mass of the foundation should exceed the mass of the unit by 2 ... 3 times; The transmission of rotational movement from the electric motor to the pump is carried out by a cunelar transmission.
