Screw – spindle pumps belong into the group of volumetric pumps. The main working elements of the pump are three screw (helical) spindles (with special profile) and sleeve (casing). Screw spindle pumps can be compared with gear that have big screw length of his teeth or with piston pump which indefinite number of pistons. Pumps are made in horizontal and vertical accomplishment with adequate fitting flanges in horizontal or vertical position. Working spindles are totally hydraulically disburdened of axial forces. Fluid is moving axially without turbulence and mixing which enables pumping of a lot of viscous fluids without making foam.
Sealing is made with help of oil seals (simmering) which are disburdened because they work under pressure at the suction. The shaft sealing also could be arranged by soft packing or mechanical seal. On special demand the pumps could be furnished with mechanical seal in accordance with the characteristics of the liquid and the operating conditions, including the possibility of sealing with cartridge mechanical seal.
