High-flow stormwater dewatering and pit evacuation applications require pumps that can handle significant volumes while maintaining resistance to corrosive environments. The Zenit DRSTEEL75MA is a 0.75 kW submersible drainage pump constructed from AISI 304 stainless steel, suitable for heavy dewatering, pond drainage, and rainwater harvesting applications requiring high flow and head capacity. The internal cooling system enables operation even when partially submerged, with a standard float switch providing automatic level control.
Maximum head reaches 16 metres with a maximum flow of 330 L/Min, powered by a 240V single-phase motor drawing 5.6 Amps. The 0.75 kW motor operates at 2900 rpm, delivering consistent hydraulic performance. These specifications suit high-flow dewatering applications where both flow rate and head are important considerations.
Hydraulic design incorporates a multi-channel open impeller with a free passage of 12 mm, with the impeller manufactured from AISI 304 stainless steel. The open channel configuration maintains hydraulic efficiency while processing minor solids typical of stormwater and pond drainage applications. The hydraulic system is constructed from AISI 304 stainless steel throughout for consistent corrosion resistance.
Construction features an AISI 304 stainless steel casing and impeller with a chrome-nickel steel lifting handle. The sealing arrangement uses three mechanical seals with food-grade oil lubricated oil sump. Motor protection includes Class F insulation, IP68 rating, thermal protection, and a capacitor. Cable length is 10 metres with Shuko plug, and the unit weighs 8.4 kg.
