The 6-in. rotary wellpoint pumps from Thompson Pump & Manufacturing Co. are the original rotary wellpoint pumps designed decades ago by the company’s co-founder, George Thompson. The company says that with unassisted priming and automatic re-priming, the 6RW pump features high air handling and large water volume capabilities – up to 1,400 gpm and heads up to 80 ft., with operating speeds up to 2,000 rpm. In addition, the low-horsepower engine is a Tier 4 Final Isuzu, with diesel oxidation catalyst aftertreatment. The 6RW pump is designed for wellpoint and sock dewatering applications, and can be used in place of a comparable 6-in. vacuum or piston pump.

Pumps improve efficiency, prevent contamination

The Avant series from Tsurumi America is a line of submersible, explosion-proof pumps created to deliver excellent performance and increase cost savings on a range of wastewater applications, according to the company. The pumps feature a modern design and IE3 premium-efficiency motors that deliver high performances and withstand continuous-duty cycles, the company says. The series was certified in accordance with FM Global explosion-proof specifications to ensure products conform to the highest standards. Additionally, they have an exclusive closed-circuit cooling system, utilizing a water-glycol mixture that prevents contamination of the system while cooling the motor. Customers can order tailor-made Avant pumps from the factory, with specific configurations that match the demands of their jobs while boosting results, Tsurumi says.

Shaft seals for aggressive environments

Schurco Slurry’s shaft seal arrangement for slurry pumps can replace standard packed stuffing box arrangements and does not require pressurized flush water, the company says. Developed in partnership with a mechanical seal manufacturer, Schurco’s custom-engineered seal is specifically tailored to the aggressive environments to which these pumps are applied. Instead, the seal utilizes a grease barrier fluid that quenches the inner-seal chamber to keep it both lubricated and cool for the life of the seal. The slurry pumps can then run continuously without the need for flush water with near-zero external leakage. According to Schurco Slurry, the seals are a cartridge design, which, after a brief training, can be easily maintained by most maintenance staffs.
