Rotary Piston Pumps & Systems, NT Series

Rotary Piston Pumps & Systems For General Industrial Applications

NASH’s NT series rotary piston pumps range in nominal capacity from 150 to 778 ACFM. These pumps are capable of achieving vacuum levels down to 0.01 Torr. The NT models include a cutting-edge triplex piston design that provides quiet and vibration-free operation. 

In addition, a standard internal positive pressure lubrication system ensures highly reliable lubrication at all inlet pressure levels. Supplied by a gear pump, the oil is directed through porting in the shaft and routed to each triplex piston. As the oil is pressurized, it prevents contact between the pistons and their respective eccentric cams, which significantly reduces operational wear. 

Whatever the inlet pressure, our rotary piston pumps operate efficiently from blank off to atmosphere without overloading the motor. The NT series minimizes water consumption, as the sealing fluid used is recirculated oil instead of once-through water sealed design.
