|
|
|
General
The
MKBBS Series Vacuum Booster Pump with overflow valve is the derivative of the
MKBS Vacuum Booster Pump. It is a type of positive displacement vacuum pump,
also called Mechanical Booster Pump. It is one of main pumping equipment to
acquire middle-level and high-level vacuum.
Its operation principle is similar to MKBS Vacuum Booster Pump: simultaneous
rotation of 8-shape rotors at a constant speed makes suction & exhaust of
gases.
Model MKBBS Vacuum Booster Pump with overflow valve is widely used for vacuum
gas pumping in metal and non-metal material industry; Vacuum melting, vacuum
surface treatment, space simulation in astronomy industry and manufacture of
vacuum cooling drying equipment. If it connects with Water Ring Vacuum Pump of
Liquid Ring Vacuum Pump, it can be used for vacuum distilling, vacuum drying
and for vacuum crystallization, etc.
 Model MKBB
Features
1.Protective
overload function due to the automatic functioning of the overload valve. In
general, it is necessity to install vacuum electric relay.
2.Must be used with backing pump.
3.The pump and backing pump can be started at the same time so that pumping
time decreases.
4.Comparing the MKBS series Vacuum Booster Pump, it can operate at higher inlet
pressure. It is more suitable for Booster Liquid Ring Vacuum System operating
at higher pressures and it is able to exhaust large amount of condensable
vapour.
5.Possesses all advantages of MKBS series Vacuum Booster Pump.
6.Higher pumping speed in a larger pressure range. (1~1.3×10E2Pa).
7.No oil in pump casing to avoid oil vapour polluting vacuum system.
8.Low vibration, low noise.
9.Little mechanical friction loss, and lower drive power.
10.Easy for maintenance, service and long service life.
11.Suitable for emergent exhaust of vacuum system.
12.Most of components are exchangeable due to unique manufacturing process.
