Why Should You Consider an Oil-sealed Liquid Ring Vacuum Pump System?

Get the best reliability under the toughest conditions.

Oil-sealed liquid ring vacuum pump systems give maximum reliability under the toughest conditions. These highly efficient systems are known for their simple design and low maintenance needs due to the lack of wearing parts. Compared to other vacuum pump systems, these systems offer advantage of no metal-to-metal contact between the impeller and casing. In addition, they require no internal lubrication.

The Advantages of Oil-sealed Liquid Ring Vacuum Pump Systems

There are many more advantages to using an Oil-sealed Liquid Ring Vacuum Pump system. Overall, these systems can help you save money on energy and overhead costs.

By using specially formulated low vapor pressure sealing fluid, they can operate up to 10,000 hours or more without an oil change, while stopping corrosion and scale build-up in its tracks. An additional advantage of oil-sealed systems is that the use of water – and the corrosion and waste associated with it – has been completely eliminated.

The air/oil separator virtually entirely eliminates oil carryover concerns and ensures the cleanest environment. Switching from water-cooled to air-cooled will also produce significant cost savings on water usage and reduce groundwater runoff contamination. A few more advantages include:

  • Low maintenance
  • Durable
  • Extremely quiet with sound levels in the 75-80 dBA range
  • High capacity for contaminants
  • Can operate at low vacuum without overheating
  • Offered in single or two-stage pumps
  • Available in air-cooled or water-cooled
  • Available explosion-proof
  • Eliminates the use of water

Adaptability At Its Core

The oil-sealed vacuum pump is also very adaptable to the utilization of a Variable Frequency Drive (VFD). The VFD is applied in industries where ruggedness, reliability and cost-effective operation are of the utmost importance. When demand for vacuum decreases, the VFD will reduce the speed of the vacuum pump, which in turn significantly reduces power consumption. VFD’s are affordable and easy to install and are one of the most cost-effective ways to maximize efficiency and reduce operating costs – frequently saving up to 50% in energy costs.
