The OVT priming system is reportedly an improvement on the traditional vacuum priming system by allowing for a basic pump to prime automatically, with lower maintenance and higher air handling for faster priming. The OVT system’s non-contacting rotors eliminate internal wear which increases longevity and provides the reliability of no decrease in performance over time.

 The OVT system offers lower maintenance and operating expenses because the system is dry running. No recirculating oil is needed, which eliminates any possible smoke, mist, or pollution that traditional priming systems may experience. Traditional vacuum priming systems can require service every 5000 hours while the OVT priming unit only requires service every 20,000 hours, which is 4 times less.

 The Thompson OVT system have high vacuum capability with deeper suction lifts of 28.4 in Hg and 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.

It is suitable for applications from sewer bypassing to wellpoint dewatering.
