Dry Prime Trash Pumps


Thompson Pump offers the revolutionary Compact pump series featuring all the benefits of the popular Thompson Pump JSC series with the added advantage of a smaller compact size, lighter weight, fewer parts, less maintenance and lower price. The Thompson Compact pump is 35% smaller and 20% lighter but offers the same great performance as a standard size pump with a 24-hour run time fuel tank. Available in the most common diesel-drive portable pump sizes of 4” and 6”, the Compact series offers an economical alternative to similar sized portable pumps – a significant savings compared to standard 4” and 6” compressor-assisted pumps. Best of all, Thompson Pump’s Compact pump series includes the revolutionary Enviroprime System® which provides reliable, automatic priming with the environmental advantage of not spilling pump fluids onto the ground.
