TDP5.5-3, TDP7.5-4 & TDP11-4 | Heavy-Duty Submersible Dewatering Pumps
description Overview
TDP5.5-3, TDP7.5-4 & TDP11-4 | Heavy-Duty Submersible Dewatering Pumps
This high-power group spans 5.5 to 11 kW three-phase dewatering pumps for the largest drainage and slurry jobs. Semi-open SS304 impellers with SS304 wear plates handle heavy abrasive water, delivering up to 84 m³/hr and heads up to 48.5 metres. The 3-inch and 4-inch top outlets keep large volumes moving with efficient motor cooling.
Built for mines, quarries, major construction and civil projects, all three submerge to 50 metres on a 0.5 MPa mechanical seal and run on a 380-420V three-phase supply. The hermetically sealed IP68 motor includes built-in thermal protection against overheating and over-current.
