The Dri-Prime NC350 pump from Godwin, a Xylem brand, delivers flows to 6,530 gpm and discharge heads to 160 feet. It can prime and reprime from dry to 28 feet without operator assistance. Applications include sewer bypasses at lift stations and gravity sewer lines.

“Dri-Prime NC Series pumps incorporate Flygt N-technology, providing self-cleaning reliability and sustained hydraulic efficiency,” says Michael Delzingaro, vice president and director of sales for Godwin. “The N-technology comprises an optimized, multivane impeller designed to achieve maximum hydraulic efficiency.”

The impeller has a back-swept horizontal leading edge that, together with the guide pin, slices stringy solids. The relief groove on the insert ring offers a self-cleaning mechanism and acts as a pump within a pump, pushing compressed solids through the pump and out.

“This sustained efficiency means clog-free performance,” he says. “With the wear resistance provided from our hard iron impeller and wear plate, this means less downtime and operator assistance. Reducing downtime minimizes the costs of using the pump for the operator or municipality.”

The pump has a 16-inch suction connection and 16-inch delivery connection. Maximum operating temperature is 176 degrees F, maximum working pressure is 70 psi, maximum suction pressure is 58 psi and maximum operating speed is 1,200 rpm.

“Wear resistance is another critical piece where you look at the hardness of the materials,” Delzingaro says. “In our case we have a hard iron impeller and front wear ring that helps decrease wear from some of the abrasiveness that you see with water and wastewater over time.”

The standard Caterpillar C9 (T3 Flex) engine delivers 300 hp at 1,800 rpm and has a maximum fuel consumption of 15.1 gph at 1,800 rpm. The pump and engine have dry and wet weights of 16,020 pounds. It is 15.4 feet long, 6.9 feet wide and 8.25 feet tall. The optional John Deere 6090HFC94 (IT4) engine delivers 302 hp at 1,800 rpm and has a maximum fuel consumption of 14.7 gph at 1,800 rpm. The engine and pump have dry and wet weights of 16,880 pounds. It is 15.5 feet long, 6.9 feet wide and 6.9 feet tall.

The pump is also available with an electric motor or as a Critically Silenced unit (noise level less than 70 decibels at 30 feet) or as a Godwin DBS for pump station backup. 800/247-8674; www.godwinpumps.com.
