Why Oil Seal over Traditional

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 self-contained oil sealed system over a traditional water sealed system include:

-Eliminate water usage 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 systems 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 schedule maintenance.

Engineered for Rigorous Duty

Our Vectra oil seal systems centered around the Vectra CL liquid ring vacuum pumps. Engineered to stand up to harsh environment in the chemical and oil & gas industris, the Vectra XL offers capacity ranging from 29 to 5,238 ACFM (50 to 8,900 m^3/hr).


Versatile Design

Each self-contained system is complete with all 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 clearance or mental-to-mental contact. This allows the oil sealed liquid ring package to provide the benefits of rotary vane or screw pumps without their disadvantages.
