Thompson Pump’s new Compact pump series has all the benefits of the popular Thompson Pump JSC series but is lighter, has fewer parts, needs less maintenance, and has a lower price. The Thompson Compact pump is 35% smaller and 20% lighter but offers the same performance as a standard size pump with 24-hour run time fuel tank. Available in the most common diesel-drive portable pump sizes of 4 inches and 6 inches, the Compact series offers an economical alternative to similar-sized portable pumps—at a significant savings compared to standard 4-inch and 6-inch compressor-assisted pumps. Thompson Pump’s Compact pump series includes the Enviroprime system, which keeps pumpage from discharging into the environment. (
