SMT16B

Dry and submersible screw pumps for low pressure, no noise applications up to 40 bar

SMT16B are three screw pumps for industrial use at low pressure (up to 40 bar). SMT16B pumps are the reliable and no noise solution for industrial applications where long life and very smooth fluid flow are required. SMT16B pump is a priming pump assembled into a pump body. 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 mechanical wearing.

The advanced design and high precision of screw manufacturing ensure a very low level of acoustic emissions and pulsations. The geometry and high precision machining of the three screws create sealing chambers. During the rotation of the screws, the main screw creates a cavity that holds the fluid and drives it smoothly in the axial direction from the inlet to the outlet port.

SMT 16B pumps may have internal or external safety relief valves. SMT16B has shorter screws compared to SMT pumps, to be used in application where the space is restricted.
