Types of Liquid Ring Vacuum Pumps

State of the Art

NASH Vectra Liquid Ring Vacuum Pumps

Vectra Series

XL – Vectra XL pumps were designed with the chemical industry in mind. Using state of the art design tools and input from some of the world’s largest chemical manufacturers, the Nash Vectra XL takes liquid ring vacuum pumps to new levels of reliability and operational performance. Patented cone and rotor designs, discharging against back pressure, and ATEX certification are just a few of the many features of the XL

GL – Vectra GL pumps were designed for general industrial applications. Incorporating many of the same features of the XL, the GL provides a more compact design with built in mechanical seals. Fewer options leads to a lower first cost product.

SX – Vectra SX pumps blend legendary Nash features with a small pump package. Available in monoblock or lantern drive styles, the Vectra SX is also offered in water handling or high vacuum configurations. Perfect for end user or OEM applications that demand the highest quality, low cost vacuum pumps – in smaller sizes!

What are Common Applications of Liquid Ring Vacuum Pumps?

Vacuum pumps are used throughout Michigan in a variety of industries, including power plants, food processing, chemical, and paper.

Chemical

The chemical industry relies on liquid ring vacuums to lower the pressure inside distillation columns and reactor vessels and to compress gases. Waste gas recovery helps keep you in compliance.

Paper Industry

Many Michigan paper processing plants rely on the NASH pump to remove water from the paper stock as it is moves through the paper machine. For our clients, we provide boroscope inspections to estimate the condition of installed equipment, comprehensive repair services, and, new and remanufactured equipment where appropriate.

Food Processing

We’ve worked with many plants in the food industry to process ingredients at low pressure (in a vacuum) to reduce moisture content with less chance of scorching the products. Vacuum is also used to aid in the filtration and drying of product.

Power Industry

The power industry uses a NASH pump package as a condenser exhauster. If your condenser exhausters are a very old design with limited parts availability, consider NASH liquid ring pumps. We can also help with your water box priming applications, ash handling and flue gas desulphurization.
