Liquid Ring Vacuum Pump

Small Capacity, Vectra SX

Capacity 15 to 150 ACFM (25 to 260 m3/h)

The NASH Vectra SX liquid ring vacuum pump and compressor series delivers optimum performance with unprecedented production efficiencies. Available in 5 models, the capacities of the Vectra SX liquid ring vacuum pumps and compressors range from 15 to 150 ACFM  (25 to 260 m3/h), and have been designed to meet the widespread needs of the process industry.

Description

Small Industrial Pumps Engineered For Process Industry Applications

The Vectra SX line of small industrial pumps delivers proven Nash reliability and performance to a broad range of industrial applications. With five low horsepower liquid ring pump models in the 1.5 to 10 HP range at 60 Hz (0.75 to 5.5 kW at 50Hz), these pump/compressor models provide the right solution for small capacity vacuum pump requirements.

Available in monoblock and lantern pump designs, the Vectra SX compact liquid ring vacuum pump uses commercial motors for a wide range of product configurations.

Reliable And Efficient With Proven Performance

Based on proven reliable NASH conical liquid ring pump designs, the Vectra series delivers superior performance and reliability through several engineering upgrades.

Built-in mechanical seals eliminate shaft leakage

Quiet operation

NASH patented Gas Scavenging Technology dramatically improves pump performance at high vacuum levels

Low Lifecycle And Utility Costs

Vectra SX small liquid ring vacuum pumps were designed to deliver low life cycle and utility costs. Features include:

The pump body is engineered to reduce forces on the pump shaft

Operating speeds that have been carefully selected to ensure minimal wear

High-efficiency performance

Long operating lifespan

Low water flow requirement and low power consumption

The motor does not operate in the service factor, further extending pump life

High-Performance Materials

The Vectra SX includes high-quality components such as

Precision cast 304 stainless steel rotor that is standard on all units

Cast iron pump includes a corrosion resistant pump casing to reduce internal corrosion and maintain peak operating performance

Operates As A Vacuum Pump & Compressor With A Discharge Pressure Range Of 33 psia (2.3 bar abs.)

Some applications require vacuum and compression in one process. Instead of handling the gas with two separate machines, our liquid ring vacuum pump and compressor models can do the job with only one pump - reducing cost and simplifying installation.

Reliable And Efficient With Conical Porting And Rotor Configuration

Patented in 1932, Nash’s variable conical porting design allows the force of compression to counter the weight of the rotor and shaft to help minimize load on bearings during operation. The variable porting optimizes pump performance across the entire operating range. With constant innovation, Nash’s patented design features:

Option for lobe purge to minimize damage from erosion in duties with solids present

Large differential pressure capability

Gas scavenging feature minimizes slip of gas from discharge to inlet improving capacity, especially at deep vacuum

High liquid carryover tolerance

Side discharge to minimize the chance of flooded start

Self-priming design may allow the elimination of the booster pump in recirculated systems

Designed To Operate In Demanding Environments

Application-specific configurations target the varied requirements of demanding industrial processes including extrusion, evisceration, filtration, dairy, soil remediation, wastewater treatment, digester gas, aeration, drying, evaporation, distillation, laboratory vacuum, and more.
