Gator Trailer Pumps

Gator Trailer Pumps from M&L Engine
M&L Engine Gator Pumps

Gator Pumps are steel fabricated with heavy duty structural steel tubing. Cases and impellers are made of 3/8" steel plate.

Gator Trailer Centrifugal Pumps supply large volumes of water using tractor, diesel, or electric power. Trailer pumps are available with either 540 or 1000 RPM PTO drive. Operation includes backing the trailer in to the water, attaching flexible drive shaft between power unit and pump shaft and connecting industrial tubing to the discharge pipe with a clamp.

Trailer allows pumping from several sites and water levels. Maintenance is practically eliminated by a design without seals or priming devices. High flow per horsepower combined with solid steel fabrication make Gator the best trailer pump on the market.
