Screw Pumps

SMT Series

SMT pumps are three Settima screw pumps for industrial use at low and medium pressure (80 bar). SMT pumps represent a reliable and low noise component for many industrial applications where long life and low cost are required.

SMT pump is a priming pump assembled into a body pump. The three screws rotate inside the body pump 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.
