Material and motor choices 

If your application demands all stainless steel construction for added corrosion resistance and/or special motor requirements such as enclosures, voltage, and frequency the 2AV2 is the right choice for your application. The 2AV2 pumps are available in both cast iron and 316 stainless steel construction and the pedestal design accepts most C-Faced motors. 
 

Rugged and reliable 

​

We focused on durability and dependability when we developed these liquid-ring pumps. With a reinforced stainless steel shaft and sealed bearings, the 2AV2 can provide up to 20,000 hours of maintenance-free operation. 
 

Quiet operation 

​

The NASH 2AV2 is expertly designed and manufactured to be quiet and vibration free. With sound pressure levels of less than 75 dBA, it complies with the strictest noise standards, eliminating the need for additional sound attenuating devices.
