Thompson Pump and Manufacturing Company recently released a new diesel-powered dewatering pump that, it says, features high air handling and large water volume capabilities.

USA-based Thompson is a leading manufacturers of heavy-duty portable diesel-powered bypass and dewatering pumps,. The company debuted its 6 in (152 mm) rotary wellpoint 6RW-DIS-4LE2T-X pump  at this year’s CONEXPO-Con/AGG trade show in Las Vegas, held in March.

The Thompson Pump rotary wellpoint pumps are the ‘original’ rotary wellpoint pumps designed by co-founder, George Thompson, the company says.

“With unassisted priming and automatic re-priming, the 6RW pump features high air handling and large water volume capabilities – up to 1,400 gallons per minute (5,300 litres per minute) and heads up to 80 ft (24.4 m); operating speeds up to 2,000 rpm; and a low horsepower engine for better fuel efficiency – an EPA Final Tier 4 Isuzu engine (model: 4LE2T), with diesel oxidation catalyst after treatment,” the company said.

The 6RW pump, which adds to the 8RW and 12RW pumps in this family, is designed for wellpoint and sock dewatering applications, and can be used in place of a comparable 6 in vacuum or piston pump, making it a cost-effective dewatering option, according to the company. It is equipped with abrasion and corrosion resistant parts, polyurethane rotors, and stainless steel wear plates that can handle intense industrial and plant applications.

Chris Thompson, President of Thompson Pump and Manufacturing Company, said: “This 6 in version was created, in part, due to the high demand to expand the rotary pump family’s dewatering capabilities.”
