Boosted Liquid Ring Systems
In many process applications, liquid ring vacuum pumps (LRVP) are the preferred vacuum pumps for those applications due to their inherent high reliability, forgiving design, and low maintenance requirements. The only drawback to LRVPs is their limited deep vacuum capabilities as a result of their reliance on the sealant vapor pressure. This can easily be overcome via the addition of booster pumps to the inlet of the liquid ring pump which allows the system to operate below the sealant vapor pressure.
While the booster extends the operating range of the liquid ring system, it also adds a great deal of complexity in regards to sizing the vacuum pump. Wintek draws on 30+ years of experience in designing boosted systems to ensure that the booster can operate safely over the entire operating range and avoid overheating. We also ensure that the liquid ring pump can adequately back the booster even with contaminated solvents. Wintek utilizes a proprietary sizing program that is capable of simulating complex vacuum systems with a variety of process conditions and components.
Wintek has designed systems with capacities as much as 10,000 ACFM and systems capable of operating at 0.03 Torr with liquid ring pumps backing them. This capability is unique to Wintek as many other vendors do not have the expertise to design systems that meet these conditions. It is important to understand the capabilities of any potential boosted system supplier to avoid purchasing a system that does not provide a full operating range or is constantly overheating and shutting down.
