Rotary Dry Screw Vacuum Pumps by Mixrite Engineering Company

We are leading Suppliers of NASH Dry Screw Vacuum Pumps.
 

> WIDE PERFORMANCE RANGE

NASH DRY-PRO dry screw vacuum pumps achieve an ultimate vacuum of 0.05 mbar abs, and can operate at any pressure between end vacuum and atmospheric pressure. Capacities range from 47cfm (80m3/h) up to a virtual limitless amount with various backing pump options and high vacuum boosters.

> RUGGED & DURABLE DESIGN

Our DRY-PRO screw vacuum pumps featuring high vapor and liquid tolerances, are easy to service, and have a long service life – the low rotational speed ensures low noise and low vibration operation.

The shafts and screws are one solid piece, allowing for safe, problem-free design that eliminates corrosion between the screw rotor and shaft that can occur in other pump designs.

> INDUSTRIES & APPLICATIONS

NASH DRY-PRO pumps and systems are used in applications across many industries where clean, oil-free vacuum is needed.
