The popular JSV series centrifugal pumps provide automatic self-priming and large solids handling. The durable construction and highly efficient designs provide longer life, economical operations and lower fuel costs.

OIL-LESS VACUUM TECHNOLOGY
Dry running and dry-priming system with significantly high air handling.

ENVIROPRIME SYSTEM®
Environmentally friendly system that offers fully automatic priming and re-priming without blow-by.

LARGE SOLIDS HANDLING
High capacity and head performance allows JSV pumps to transfer liquids with solids up to 4 inches.

DURABLE CONSTRUCTION
Heavy-duty casing and brackets. Stainless steel shaft sleeve and tungsten carbide vs silicone-carbide grease lubricated mechanical seal.

Thompson open trash sewage pumps are specified for the really tough jobs when a self-priming pump capable of handling large solids and/or abrasive material at high heads is needed.

IMPELLER
Dynamically balanced, non-clogging, semi-open, 65- 45-12 ductile iron with rear-equalizing vanes to reduce axial loading and prolong seal and bearing life; diameter 9.74”.

BEARINGS
Heavy-duty grease lubricated to carry both axial and radial loads.

HEAD
Rugged, back pull out design, heavy-duty class 30 cast iron with tapered bore design.

DURABLE CONSTRUCTION
Heavy-duty casing and brackets. Stainless steel shaft sleeve and tungsten carbide vs silicone-carbide grease lubricated mechanical seal.

Built with a lightweight yet durable cast aluminum housing as well as a heavy-duty steel roll cage for protection, this self-priming utility trash pump is extremely portable and versatile. Able to handle solids up to 1.75 inches, it’s a perfect choice for small dewatering jobs.

SUCTION CHECK VALVE
Built-in weighted, full-flow valve to eliminate re-priming with each cycle. Constructed of cast-iron and two-ply nitrile rubber with nylon reinforcement.

IMPELLER
Dynamically balanced, two vane, non-clogging, semi-open, class 30 cast iron with rear-equalizing vanes to reduce axial loading and prolong seal and bearing life. Diameter 5.1”.

SOLIDS HANDLING
Up to 1.75 inch solids handling.

DURABLE CONSTRUCTION
Heavy-duty steel protective roll cage.

Designed to eliminate suction lift limitations in deep manholes or excavations over 25 feet deep, the Hydraulic Submersible pump handles up to 4.25 inch solids and pumps efficiently at heads up to 240 feet.

LINKED
Thompson’s hydraulic submersible pumps are paired with a diesel-fueled power unit that remains on land while the pump head is submerged underwater nearby.

FLOTATION BARRELS
A 2 or 4-barrel flotation system is available to accompany the pump head for consistent flow and positioning while submersed.

HOSE
50 Feet of hydraulic hose is included in the pump head and power unit package.

SKID OR TRAILER MOUNTED
Mobile trailer mount or a standard skid mount for more permanent applications.

Thompson hydraulic submersible pumps provide a powerful answer when high heads or high lifts become a factor on job sites. These unique variable speed and variable flow hydraulically driven submersible pumps and power units are manufactured from heavy-duty cast iron and steel for high reliability.

SUBMERSED PUMP HEAD
With the pump head being submersed in the water it is pumping, suction lift limitations no longer exist.

TRIPLE HOSE DESIGN
Three hoses connect the pump head to the power unit: high pressure, low pressure, and bypass.

BIODEGRADABLE LUBRICANTS
Pump head hydraulic lubricant fluids are biodegradable and used with the environment in mind.

TRASH TYPE STRAINER
Corrosion-resistant and durable strainer retains pump function versus sludge, muddy water, sewage, and more.

Available in single and double diaphragm models, this pump can be indefinitely ran dry without damage to the unit. An excellent choice for pumping muddy water, sludge or any liquid with a high percentage of solids up to 2.375 inches in size, this versatile pump is lightweight yet highly resistant to abrasive and corrosive liquids.

ANTI-SHOCK CHAMBER
Air cushion chamber reduces pulsation in suction line..

CONVENIENT MAINTENANCE
Parts subject to wear are designed for quick and easy replacement when needed.

NON-CLOGGING VALVES
Oversized check valves are designed to prevent clogging.

INDEFINITE DRY RUNNING
Automatic dry priming pump can run dry indefinitely without harm.
