Sound Attenuated
Global Pump SoundGuard Enclosure
12-gauge Galvannealed-Steel (or optional stainless steel), double-sided galvanneal sheet panels insulated with a 1" thick acoustical foam barrier fire retardant composite reduces noise level to no more than 68 db at 30 feet (9 m). Designed for upward exhaust of combustion gases and cooling air. Panels are removable for maintenance and repair. Panel doors, with locks, for access to the pump, engine, priming system, and controls for routine servicing, lubrication, and fueling.
Global Standard Rotary (GSR) Wellpoint
Global Pump Rotary Wellpoint pumps make application inherent, as the positive displacement pump automatically develops the discharge pressure required.

Specifications
- Connections: 6" (150 mm) ANSI Flanges
- Maximum Pump Speed: 360 rpm
- Maximum Flow: 360 gpm (81.7 m3/h)
- Maximum Head: 81 ft (27 m)
- Displacement: 1.35 gal/stroke (5.11 liters/stroke)
- Vacuum Level: 30 ft (9 m)
- Efficiency: Up to 90%
- Fuel Consumption : (at max speed and max flow) 0.48 gal/h (1.8 l/h)
- Sound Attenuated: 72 dBa at 33 ft (10 m)
- Piston Type: Double Acting1 ft. (27 m)
