New Pump for Sale

New Thompson Diaphragm Pump (Dry Prime) for Sale

Particularly useful for pumping muddy water, sludge or any liquid with a high percentage of solids - one of the best features of the diaphragm pump is the ability to run dry indefinitely without damage. Available with a gasoline, electric or diesel engine.

Thompson diaphragm pumps are capable of quick, dry self-priming down to 20 feet in a few seconds.

They can run dry indefinitely and no rotating part comes in contact with the liquid. There are no problems with mechanical seals or packing since they are not required in a diaphragm pump. Thompson diaphragm pumps are designed to be highly resistant to abrasion and, therefore, can handle liquids containing a large percentage of sand or other abrasives. These pumps can handle large solids and stringy, fibrous materials. The parts subject to wear and aging, such as diaphragms and check valves, are easily replaced. Thompson Pump offers a unique feature on their double diaphragm pumps - the extended operating version (EOV). Instead of the normal eight hours of operation, you get up to 100 hours of continuous operation without the necessity of adding fuel or changing oil. Thompson diaphragm pumps are available with gasoline or diesel engines and with electric motors. They can be mounted on skids, roll cages or a variety of trailers.

FEATURES

  • ANTI-SHOCK CHAMBER: Air cushion chamber reduces pulsation in suction line.
  • NON-CLOGGING VALVES: Oversized check valves are designed to prevent clogging.
  • CONVENIENT MAINTENANCE: Parts subject to wear are designed for quick and easy replacement when needed.
  • INDEFINITE DRY RUNNING: Automatic dry priming pump can run dry indefinitely without harm.
  • WORKING PRINCIPLE: The JSC’s Enviroprime System® uses an air compressor to separate air from water, which keeps the pump’s venturi from clogging. An air compressor supplies air to a venturi, providing powerful air suction to the chamber located at the pump inlet. The chamber empties air from the pump’s suction line causing it to fill with water. When the suction line is fully primed, an internal float rises in the Enviroprime System® chamber, shutting off the air suction.

  • WORKING PRINCIPLE: As an option, Thompson Diaphragm Pumps fit a spring connecting rod which comes into operation if irregularly shaped solids block the diaphragm downstroke. It also operates when the pump is used on flooded suction, and sand or powders tend to settle and harden while the pump is stopped. When the pump restarts, the spring operates for a few strokes until the powder is remixed with the liquid. It is preferable to operate the pump on suction lift.
  • Durable Materials: Some models available with stainless steel and cast iron.Also available with telemetry.
  • Rugged Port Construction: Suction/discharge port stainless wear plates with Viton neoprene flapper valve.
