Thompson Pump Promotes Rotary Wellpoint Pump for 2010 NASTT No-Dig Trade
Thompson Pump features rotary wellpoint pump in 8 and 12 inch models, handling 1,750 and 3,000 gallons per minute (GPM), respectively. The maximum head is 50-feet. The pumps feature abrasion and corrosion resistant wetted components at the pump end and seal, which increase pump life span and reduce operational costs. The rotors are heavy duty steel, with polyurethane coating, while the rotor housing and bearing housings are cast aluminum.
Port Orange, FL, January 31, 2010 --(PR.com)-- Thompson Rotary Wellpoint Pumps Revolutionize the Industry
When George A. Thompson started Thompson Pump & Manufacturing in Florida in 1970, he found most companies were ineffectively handling many dewatering applications. Florida’s high water table requires dewatering prior to digging, excavation, piping or sewer work, but many companies were using inefficient vacuum-assisted centrifugal pumps as part of the wellpoint dewatering system to remove the groundwater. Because the vacuum-assisted pumps had the potential to stop working when excessive air entered the system and often required considerable maintenance, Thompson saw an opportunity to adapt the rotary pump to handle wellpoint applications. His invention subsequently revolutionized the wellpoint dewatering industry and set the standard for Thompson Pump.
Wellpointing is accomplished by driving hollow tubes vertically into the ground. Groundwater seeps into small slits in the tubes, which subsequently empty into a larger “header” pipe that is attached to the suction end of a pump. As the water is collected, a high proportion of air is collected as well.
Thompson redesigned the rotary pump’s seal and bearing arrangement for better pumping performance, and revised the discharge and suction tanks to handle water in large volumes and make the tanks capable of handling solids in the water. High adaptation allowed the rotary pumps to pump even with a large number of air leaks in the suction system. Prior to Thompson’s redesign, rotary pumps were used primarily for moving heavy liquids in “controlled” conditions – clean fluids free of air and in ideal suction conditions.
Rotary wellpoint pumps operate by rotating a pair of rotors inside the pump housing, creating a vacuum. The rotors mesh together to form cavities at the pump inlet, drawing water through the system. The water is discharged into the cavities that occur on the other side of the rotors.
