This wet rotor circulator pump is specifically suited for installations where bronze construction provides resistance to corrosion in hot water applications.\u003c\/p\u003e\u003cp\u003eThree speed manual selector provides flexibility across operating conditions. Speed 1 at 1150 rpm consumes 70 W at 0.32 A, Speed 2 at 1650 rpm draws 102 W at 0.46 A, and Speed 3 at 2300 rpm consumes 114 W at 0.50 A on 240 V single-phase supply. Maximum head is approximately 5.5 m with flow capability reaching 91.7 L\/Min.\u003c\/p\u003e\u003cp\u003eConstruction features a bronze pump casing with threaded ports and ceramic rotor-shaft assembly. Graphite bearings provide low friction operation, while the composite impeller ensures efficient hydraulic performance. The wet rotor design uses pumped liquid for bearing lubrication, contributing to reliable operation.\u003c\/p\u003e\u003cp\u003eInstallation is supported through barrel unions with threaded ports for direct pipe work connection. The pump accepts liquid temperatures from -10°C to +110°C and is rated IP44 protection class. A built-in capacitor provides high starting torque, while the integrated overload protection safeguards the motor against electrical faults.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBronze pump casing providing corrosion resistance for hot water applications\u003c\/li\u003e\n\u003cli\u003eThree speed manual selector switch for adaptable operation\u003c\/li\u003e\n\u003cli\u003eCeramic rotor-shaft with graphite bearings for reliable performance\u003c\/li\u003e\n\u003cli\u003eComposite impeller for efficient hydraulic characteristics\u003c\/li\u003e\n\u003cli\u003eWet rotor design with pumped liquid bearing lubrication\u003c\/li\u003e\n\u003cli\u003eThreaded ports with barrel unions for simplified installation\u003c\/li\u003e\n\u003cli\u003eIntegrated overload protection for motor safeguarding\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Davey","offers":[{"title":"Default Title","offer_id":50979762667767,"sku":"SB30-25","price":835.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/davey-sb30-25-bronze-3-speed-circulator-pump-for-hot-water-systems-with-composite-impeller.png?v=1785239191","url":"https:\/\/foundationpumps.com.au\/products\/davey-sb30-25-bronze-3-speed-circulator-pump-for-hot-water-systems-with-composite-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
