Thompson Pump & Mfg.

The Thompson Compact pump is 35 percent smaller and 20 percent lighter that the Thompson Pump JSC series but offers the same great 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 and 6 inches, the Compact series offers an economical alternative to similar sized portable pumps – a significant savings compared to standard 4- and 6-inch compressor-assisted pumps. Reliability is increased by the removal of several redundant parts that are no longer needed with the latest diesel engines. Best of all, Thompson Pump’s Compact pump series includes the revolutionary Enviroprime system, which keeps pumpage from discharging into the environment. The Compact series is available with the most sought after developments such as automatic start/stop and Silent Knight sound attenuation, among a few. 800.767.7310,
