This heavy duty waste pump out is ideal for large commercial applications and deflooding jobs. A 1/8 HP DC motor runs on 12 volt DC current drawing 11.5 amps. The diaphragm pump runs from a 170 RPM gear drive system and pumps five gallons per minute. This durable pump out can run dry without damaging the unit and will meet most any challenge you encounter. The diaphragm design means problem free pumping even with gravel or large particles in the flow – and there’s no filter screen to clean!
