Everyone knows the adage, “If it ain’t broke, don’t fix it.” While many attendees of the Water & Wastewater Equipment, Treatment & Transport (WWETT) Show come to see innovations, plenty also learn about proven products. One of those was on display in the Godwin, a Xylem brand, booth.

The 3-inch CD80M Dri-Prime automatic priming centrifugal pump is a compact and highly maneuverable portable system that can deliver up to 450 gpm and 93 feet total dynamic head. Jeff Fata, branch manager of Godwin’s office in Lansing, Illinois, says the unit fits across multiple industries and applications.

“This pump is great for dewatering, but can also be used in small wastewater bypass operations,” he says. “Because it’s a smaller pump, it is easy to handle, yet offers performance comparable to many bigger pumps.”

The pump comes mounted on a highway trailer or skid and includes an integral 30-gallon fuel tank. A recessed impeller model is available for high-solids streams. Indefinite dry running is no problem. The Dri-Prime system makes oversight and maintenance easy.

“It has a PrimeGuard controller, which is a state-of-the-art control system with automatic start/stop,” says Fata. “If you’ve ever had to venture out in a late-night rainstorm to prime a pump, you’ll appreciate the automatic self-priming features.”

The unit includes a close-coupled centrifugal pump with vacuum priming compressor mounted to a diesel or gasoline engine. It has cast iron construction with a cast chromium steel impeller (also available in 316 stainless steel). The pump handles raw sewage, biosolids and liquids with solids up to 1 5/8 inches. It has abrasion-resistant solid silicon carbide interfaces and a solids-handling, mushroom-type non-return valve with renewable flexible rubber seat and quick-release access.

Maintenance is typically limited to checking engine and seal cavity oil levels. The standard engine is a Yanmar 3TNV76, but alternatives include Lister, Hatz, Perkins and Deutz. A silence pack is available for use in populated areas.

“Just this week alone we talked to people in the construction industry and general contractors, along with municipalities that would use the CD80M for sewer bypass and dewatering at their wastewater treatment plants,” Fata says. “We’ve had this pump on the market for a while, but we still consider it one of our mainstays.”

Godwin technicians continue working on innovations to bring to WWETT in 2017, including new low-emission engines and control panels that can be operated remotely via a smartphone.

“With the large fuel tanks, Dri-Prime system and these controls, our pumps will be completely operable offsite,” says Fata. “Efficiency is the wave of the future. That’s what people are looking for here, and that’s what we’re offering.” 877/959-9881; www.xylem.com/dewatering.
