Thompson Pump manufactures a new priming system with OVT (oil-less vacuum technology), configured with the new John Deere interim tier 4 engine. The Thompson OVT system offers high-vacuum capability with deep suction lifts of 28.4-inches Hg, and also maintains high vacuum at lower speeds. This air-cooled priming system has no water levels to check and no cooling system to maintain, allowing the OVT priming system to perform in a variety of applications, from sewer bypassing to wellpoint dewatering. The system is dry-running – no recirculating oil is needed, offering an eco-friendly alternative – and the OVT priming unit also only requires service every 20,000 hours.
