Original Press Release:

Nash® Extends Product Portfolio with line of DRY-PRO® Dry Vacuum Pumps for Pharmaceutical and Chemical Applications.

Nash is pleased to announce the addition of the NASH DRY-PRO line of dry vacuum pumps and systems. The dry and contact free operation of the DRY-PRO requires no lubrication in the pumping chamber. This translates into major advantages: no process contamination and no pollution caused by the pump operation.

The NASH DRY-PRO line offers dry screw vacuum pump designs with fixed or variable pitch screw rotors. DRY-PRO pumps achieve an ultimate vacuum of .0015”Hg (0.05 mbar abs), and can operate at any pressure between end vacuum and atmospheric pressure. Capacities range from 47 cfm (80 m3/h) up to an almost limitless amount with backing pump options and high vacuum boosters.

The high vacuum, and seemingly endless capacity of this pump series combined with its safe and dry operation make it ideal for processes in the pharmaceutical industry and in fine chemical processing applications.

The rugged and durable pump design offers high vapor and liquid tolerances, and can handle corrosives, organics, inorganics, and solvents because of its oil free, non-contacting screw design. In this design the shafts and screws are one solid piece, which allows for a safe, problem free operation that eliminates corrosion between the screw rotor and shaft that can occur in other pump designs. A low rotational speed ensures low noise and low vibration operation

NASH DRY-PRO pumps are easy to service and have a long service life. All DRY-PRO pumps and systems are backed by a NASH Certified Performance Guarantee, and Nash’s global network of service and support.
