6798

Generac 6798 Electric Diaphragm Pump (1800 GPH, 2in, 3-Phase)

The Generac Power Systems 6798 Electric Diaphragm Pump is a heavy-duty 2-inch industrial-grade dewatering pump designed for demanding construction, utility, and flood control applications. Built with a rugged diaphragm pumping system, it is capable of handling dirty water, sludge, sand, and solids-laden fluids without the clogging or impeller damage issues found in conventional centrifugal pumps.

Powered by a 3-phase electric motor, this model delivers reliable continuous-duty performance with low maintenance requirements and stable high-torque operation. With a maximum flow capacity of 1,800 GPH (30 GPM), the 6798 is ideal for trench dewatering, foundation work, confined-space pumping, and emergency water removal where consistent performance is critical.

The diaphragm design allows the pump to run dry without damage, making it highly suitable for intermittent water conditions commonly found on job sites and disaster response environments.
