Rehab Focus: Bypass Pumps and Pumping

December 2009 Vol. 64 No. 12
Gorman-Rupp's PAV3B60C-3TNV70 three-inch pump.

The unique top discharge design on the HS103 enables the pump to fit through a 21-inch diameter opening. The simple-to-maintain gear motor with “plug-in” connection allows for quick changeover when needed. A standard Godwin PrimeGuard Controller provides programmable operations including setting maintenance timers and automatic starting and stopping. A safety shutdown system in the engine controls prevents equipment damage from engine fault or failure, while the integral 60 gallons fuel tank capacity provides hours of continuous operation. “Quick Disconnect” hydraulic fittings simplify setup, installation and shutdown of the HS103. 856.467.3636, www.godwinpumps.com

Rain for Rent

With a remarkably high flow rate, up to 10,000 gpm, the 12-inch DV-300c-E Power Prime pump, sold and rented by Rain for Rent, handles 3-inch solids, has a variable frequency drive (VFD), and produces total dynamic head up to 190 feet. The VFD and inverted rated motor use the available 250-hp only as necessary to produce heads and flows otherwise unavailable with standard electric pumps. The DV-300c-E is up to 84 percent efficient at BEP, providing even more energy savings. 800.742.7246, www.rainforrent.com

Global Pump

The Global HYD (Hydraulic Submersible) series of pumps range in sizes from 4-12 inch with flows of 625 to 8,000 gpm. They are also capable of handling solids up to 5 inches. Practical applications include, but are not limited to, sewer bypass and liquid transfer. These hydraulically driven submersible pumps are driven by diesel powered hydraulic units. The hydraulic submersible pumps are not affected by suction lift limitations. These pumps can operate where electric power is not available, and in applications where the suction lift exceeds that of other pumps. The hydraulic power units are available in skid or highway legal trailer formats. Other hydraulic tools and equipment may also operate from the power unit. 866.360.7867, www.globalppump.com
