SMT*6B are three screw pumps for industrial use at low and medium pressure (*0 bar). SMT*6B pumps represent a reliable and low noise component for many industrial applications where long life pump and low cost are required. SMT*6B pump is a priming pump assembled into a body pump. The pump body and the design of the screws avoids any axial load. The functional pressure develops some tolerance between the balancing piston of the main screw and the surrounding body. This creates a balancing hydrodynamic force of the screws and, at the same time, lubricates and cools down the sealing parts. The torque needed to move the lateral screws is transmitted hydraulically by the pumped fluid. This means that the screws rotate with no possibility of wearing.

The high quality of screw manufacturing ensures a very low level of acoustic emissions and pulsation.

The geometric design of the three screws creates sealing chambers. During the rotation of the screws, the main one creates a sort of cavity that holds the fluid and drives it with an axial direction from the inlet to the outlet port. SMT pumps may have internal or external relief security valves. SMT*6B has shorter screws compared to SMT pumps, to be used in application where the space is restricted.
