Settima Screw Pumps

SM pumps are three screw pumps for industrial use at low and medium pressure (80 bar).

SM pump is a priming pump assembled into a pump body. The three screws rotate inside the pump body and the design of the screws avoids any axial load. The functional pressure develops some tolerances between the balancing piston of the main screw and the surrounding body.

This creates a balancing hydrodynamic force on 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.

Key features:

• For industrial use at low and medium pressure (80 bar)
• Reliable low noise instrument
• Long lift pump at low cost
