//--- META DESCRIPTION FOR BOOMTRAIN---//?>
Thompson Pump will showcase its priming system with OVT (oil-less vacuum technology) configured with the new John Deere IT4 (interim tier 4) engine at ConExpo-Con/Agg 2011.
The technology will be exhibited at Booth C-4945.
The OVT Priming System offers multiple improvements to the traditional vacuum priming system. While both allow for a basic pump to prime automatically, the OVT does this more efficiently with lower maintenance and higher air handling for faster priming.
In addition, the OVT system’s non-contacting rotors eliminate internal wear which increases longevity and provides the reliability of no decrease in performance throughout time.
The OVT system offers lower maintenance and operating expenses because the system is dry running – no recirculating oil is needed.
Eliminating the oil, in turn, eliminates any possible smoke, mist, or pollution that traditional priming systems may experience – offering a much improved eco-friendly alternative to prior technology. Traditional vacuum priming systems require service every 5,000 hours. The OVT priming unit only requires service every 20,000 hours – which is four times less.
Not only does the Thompson OVT system have high vacuum capability with deeper suction lifts of 28.4 inches Hg, but it also maintains high vacuum at lower speeds. This air cooled priming system has no water levels to check and no cooling system to maintain unlike traditional vacuum priming systems. These capabilities allow the OVT priming system to perform in a variety of applications from sewer bypassing to wellpoint dewatering.
Most interestingly, the Thompson OVT priming system is tolerant to accidental liquid carryover. Prior vacuum priming systems would be destroyed if liquid carried over.
