Roller Vane Pumps With Radially Moveable Vanes
|
|
Designed for developing vacuum or positive pressure (when operating as a
compressor) in the tanks of vacuum plants mounted on the chassis of GAZ, ZIL and KAMAZ
trucks, which are used for pumping out polluted liquids and liquid faeces at the ambient temperatures from
-20 to +40°C.
Air cooled roller vane vacuum pumps with sliding vanes. Both pump sizes can be made either with a clockwise or counter clockwise shaft rotation
(if viewed from the drive side).
The power transmission from the motors to the pumps is made either by V-belts or directly with a universal joint from the motor vehicle power take-off
shaft. |
