Thompson trash pumps are specified for the really tough jobs where a wet priming pump capable of handling large solids and/or abrasive material is needed. Thompson’s pumps outperform other centrifugal trash pumps on the market and cost less to operate.

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.

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.

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.

With a 6, 8 and 12 inch rotary pump that handles both air and water, the positive displacement with constant suction makes this pump the ideal choice for all wellpoint applications.

ECONOMICAL FUEL COST
Utilizing low engine speed without compromising function means reduced fuel consumption.

POSITIVE DISPLACEMENT PUMP
High vacuum and high efficiency can be maintained at low engine speeds.

HIGH AIR & WATER HANDLING
Engineered to handle substantially more air and large volumes of water vs. other wellpoint pumps.

LONG OPERATION
Rugged, corrosion-resistant rotors and wear plates allow for extended use and operation.

Consuming only 5 gallons of fuel per day, the PW pump is the economical choice for wellpoint or sock dewatering. This high suction lift, high air handling pump is self-priming and is available with a sound attenuated enclosure.

ECONOMICAL FUEL COST
Highly efficient pump that consumes less than 5 gallons of fuel per day.

SILENT KNIGHT®
Sound-attenuated canopy reduces pump sound levels to or below 69 dBA. Fully-insulated, weather-proof and lockable.

PULSATING VACUUM
Pulsating motion created in vacuum prevents wellpoint clogging.

DURABLE CONSTRUCTION
Robust construction for durability.

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.
