It is designed for sites requiring an automated clean water supply drawn from underground wells or dams over expansive site elevations. The inclusion of a 60 litre pressure tank maximizes efficiency while overcoming pipeline resistance and significant vertical lift.\u003c\/p\u003e \u003cp\u003eDriven by a 2.4 kW single-phase 240v motor, the unit operates with a rated current draw of 14.1 Amps during operation. Hydraulic performance is characterized by a maximum head of approximately 79 m and a maximum flow rate of 92 L\/Min. This configuration is optimized for installations requiring maximum static head for automatic site water networks and irrigation tasks.\u003c\/p\u003e \u003cp\u003eThe system is factory-supplied with the WK-CJ850 water kit and a Type D mechanical switch integrated with a 60 litre pressure tank for automatic operation. The internal SW77 injector works with the jet and venturi design to maximize discharge pressure while purging air. The large 60 litre tank provides increased draw-off capacity, delaying pump starts for small demands and reducing wear on the motor.\u003c\/p\u003e \u003cp\u003eConstruction hardware includes a rugged cast iron casing and a double race bearing system to manage mechanical stress across dual bearing rows. The Type D mechanical switch contains no sensitive electronics, providing high resistance to power spikes or lightning typical of rural farm sites. The assembly is rated for liquids up to 65°C and includes a comprehensive 2-year manufacturer warranty.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eRugged cast iron pump body provides exceptional structural stability in the field.\u003c\/li\u003e \u003cli\u003e60 litre pressure tank provides increased water draw-off capacity to effectively minimize motor start cycles and save energy.\u003c\/li\u003e \u003cli\u003eWK-CJ850 water kit includes a stainless steel barrel union, gate valve, and pressure gauge for accurate system monitoring.\u003c\/li\u003e \u003cli\u003eType D mechanical switch features heavy-duty relay points for dependable automatic operation without electronic failure risks.\u003c\/li\u003e \u003cli\u003eSW77 injector configuration is tuned to deliver high discharge pressure for site distribution tasks.\u003c\/li\u003e \u003cli\u003eDouble race bearing design manages axial and radial forces effectively to significantly extend the operational life of the motor.\u003c\/li\u003e \u003cli\u003eCorrosion-resistant stainless steel shaft protects against rust and moisture.\u003c\/li\u003e \u003cli\u003eLarge oval casing holds ample water around the impeller to assist with self-priming.\u003c\/li\u003e \u003c\/ul\u003e","brand":"Orange Pumps","offers":[{"title":"Default Title","offer_id":50957416694007,"sku":"CJ850-1P-SW77-T60","price":2799.8,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/orange-pumps-cj850-sw77-shallow-well-pressure-pump-high-static-head-60l-tank.png?v=1784703606","url":"https:\/\/foundationpumps.com.au\/products\/orange-pumps-cj850-sw77-shallow-well-pressure-pump-high-static-head-60l-tank","provider":"Foundation Pumps","version":"1.0","type":"link"}
