Engineered Vacuum Systems
2AV2 Oil Sealed Packages
Capacity 95 to 340 ACFM (160 to 580 m3/h)
NASH 2AV2 Oil Sealed packages deliver reliable vacuum performance in a standard, pre-engineered system that uses oil as the seal liquid instead of water. Oil sealed packages are self-contained, eliminate water usage and disposal costs, and can attain higher vacuum levels that with water. Constructed around the reliable 2AV2 liquid ring vacuum pump, our 2AV2 Oil Sealed systems are engineered for general industrial processes, and are easily expandable to meet your growing needs.
One of the best features of the liquid ring pump is that it can operate with a multitude of different fluids as the seal liquid. The benefits of a self-contained oil sealed system over a traditional water sealed system include:
Eliminates water usage and disposal costs
Allows you to install it in remote locations where water may not be available
Allows you to attain higher vacuum levels than with water
Easy filter change without disconnecting piping
Can prevent the condensing or dissolving of a process gas
Simple Rugged Construction
At the heart of the oil sealed system is a durable NASH liquid ring pump, known to provide many years of reliable service, even in the most demanding processes. An oil sealed liquid ring system is more tolerant of carryover and wear, and it provides quiet operation. The oil is not required for lubrication which means it can operate at extremely long intervals between oil changes, easily going more than 10,000 hours with no downtime. Aside from a periodic oil and filter change, the system can run for years with no scheduled maintenance.
Engineered for Industrial Processes
Our oil seal system for general industrial processes are centered around the 2AV2 liquid ring vacuum pumps. These single single stage units offer capacity ranging from 95 to 340 ACFM (160 to 580 m3/h) and are used to extract and pump all dry and moist gases, mainly air and air/vapor mixtures, in chemical, food & beverage, and other general industrial processes.
Each self-contained system is complete with all of the components for your basic operating needs. We also offer a wide array of optional controls including alarm switches, control panels, and completely explosion-proof packages.
We can customize the system to meet your specific needs. The pump has only one moving part and no tight clearances or metal-to-metal contact. This allows the oil sealed liquid ring package to provide the benefits of rotary vane or screw pumps without their disadvantages.
