Series	Vacuum Division

Product Description

Feature

◾Low noise and low vibration
◾If desired, the liquid ring vacuum pumps are supplied also with other motors or with motors in explosion-proof design.
◾Various chemical idusstries
◾Vacuum drying of goods of food and medicien
◾As shown in the figure, a runner is eccentrically assembled into the center of the casing.

KVC Water Ring Pump

Construction type

Sealing water supplied from the suction port changes into the ringed shape of almost the same thickness on the inner wall of the cylinder by revolution of the runner.
The volume of the space surrouned by the ringed inner wall and the blade of the rummer increases and sucks in proportion to revolution and decreases and is compressed, with exhausting action through the exhaust port.
