The Zenit DRSTEEL37MA is a 0.37 kW submersible drainage pump constructed entirely from AISI 304 stainless steel, suitable for stormwater dewatering, pond drainage, pit evacuation, and rainwater collection systems. The unit features an internal recycle pumped liquid system that provides motor cooling even when partially submerged, and includes a standard float switch for automatic level control.\u003c\/p\u003e\u003cp\u003eMaximum head for this model is 13.6 metres with a corresponding maximum flow of 150 L\/Min, powered by a 240V single-phase motor drawing 3.1 Amps. The 0.37 kW motor operates at 2730 rpm and achieves a hydraulic efficiency of 55.6%. These specifications suit low-flow dewatering applications where portability and corrosion resistance are primary requirements.\u003c\/p\u003e\u003cp\u003eHydraulic design incorporates a multi-channel open impeller with a free passage of 10 mm for small solids, with the impeller manufactured from AISI 304 stainless steel. The open channel configuration maintains flow efficiency while handling minor debris common in stormwater and rainwater applications. The hydraulic system is constructed from AISI 304 stainless steel throughout, providing consistent corrosion resistance.\u003c\/p\u003e\u003cp\u003eConstruction features an AISI 304 stainless steel casing and impeller with a chrome-nickel steel lifting handle. The sealing arrangement consists of three mechanical seals with a food-grade oil lubricated oil sump, including one silicon carbide seal and one alumina graphite seal. Motor protection includes Class F insulation and IP68 ingress rating, with thermal protection and a starting capacitor included. Cable length is 5 metres with Shuko plug, and the unit weighs 6.3 kg.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMulti-channel open impeller in AISI 304 stainless steel\u003c\/li\u003e\n\u003cli\u003eInternal recycle pumped liquid cooling system for partial submersion operation\u003c\/li\u003e\n\u003cli\u003eThree mechanical seals with food-grade oil lubrication\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel strainer included\u003c\/li\u003e\n\u003cli\u003eStainless steel AISI 431 shaft material\u003c\/li\u003e\n\u003cli\u003eMaximum immersion depth of 10 metres\u003c\/li\u003e\n\u003cli\u003eMaximum starts per hour: 30\u003c\/li\u003e\n\u003cli\u003eStandard float switch on motor cover for automatic operation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Zenit","offers":[{"title":"Default Title","offer_id":50924033179895,"sku":"711352","price":945.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/zenit-drsteel37ma-stainless-steel-float-switch-drainage-pump-for-rainwater-with-multi-channel-impeller.png?v=1783508486","url":"https:\/\/foundationpumps.com.au\/products\/zenit-drsteel37ma-stainless-steel-float-switch-drainage-pump-for-rainwater-with-multi-channel-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
