It is specifically designed for small to medium households and rural properties requiring a reliable, high-pressure water source. The system manages clean water transfer from tanks, bores, and dams for continuous-duty domestic service.\u003c\/p\u003e \u003cp\u003eHydraulic performance for this 0.75 kW model reaches a maximum total head of 52 m and a maximum flow rate of 98 L\/Min at 50Hz. Operating on a 240v single-phase supply, the motor draws a rated current of 4.5 Amps. These specifications establish the delivery capacity for standard pressure boosting and garden irrigation tasks.\u003c\/p\u003e \u003cp\u003eMechanical delivery is provided by a jet-assisted horizontal single-stage centrifugal assembly. This functional design facilitates shallow well lifts of 7.6m and deep well lifts up to 27m with appropriate injector combinations. The closed impeller system focuses on maximizing pressure output while maintaining high hydraulic efficiency.\u003c\/p\u003e \u003cp\u003eStructural hardware consists of a heavy-duty Cast Iron pump casing and injector housing for mechanical durability. The internal assembly features a glass-filled polycarbonate impeller and a carbon\/ceramic mechanical seal. This complete kit is supplied with a factory-fitted pressure switch and a 24L steel pressure tank for automatic operation.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eCast Iron pump casing and injector housing provide a robust foundation for high-pressure domestic systems.\u003c\/li\u003e \u003cli\u003eJet assisted pressure pump design utilizes a venturi system for enhanced suction and vertical lift.\u003c\/li\u003e \u003cli\u003e20% Glass Filled Polycarbonate closed impeller ensures mechanical stability and long-term operating efficiency.\u003c\/li\u003e \u003cli\u003eVersatile suction performance allowing shallow well lifts to 7.6m and deep well lifts to 27m with various injectors.\u003c\/li\u003e \u003cli\u003eAutomatic system configuration featuring a factory-fitted pressure switch for reliable start\/stop control.\u003c\/li\u003e \u003cli\u003eSupplied with a 24L steel accumulation tank to manage pressure cycles and protect the motor from frequent starts.\u003c\/li\u003e \u003cli\u003eSurface mounted horizontal single-stage centrifugal design for easy installation and maintenance accessibility.\u003c\/li\u003e \u003cli\u003eInternal mechanical seal with ceramic stationary face and carbon graphite rotating face ensures a watertight seal.\u003c\/li\u003e \u003c\/ul\u003e ","brand":"Onga","offers":[{"title":"Default Title","offer_id":50947497132279,"sku":"JJ400K","price":1273.1,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/onga-farmmaster-jj400-jet-assisted-pressure-pump-domestic-water-supply-24l-tank.png?v=1784289177","url":"https:\/\/foundationpumps.com.au\/products\/onga-farmmaster-jj400-jet-assisted-pressure-pump-domestic-water-supply-24l-tank","provider":"Foundation Pumps","version":"1.0","type":"link"}
