It is engineered for rural properties where clean water from underground sources or dams must be moved over extreme site elevations. The 35 litre pressure tank provides a solution for maintaining automated high-head supply with minimal motor interventions.\u003c\/p\u003e \u003cp\u003eThe system features a 2.4 kW single-phase 240v motor that draws a rated current 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 high-pressure configuration is optimized for overcoming pipe resistance and vertical lift in automated site networks.\u003c\/p\u003e \u003cp\u003eFactory-fitted with the WK-CJ850 water kit and a Type D mechanical switch, the system utilizes a 35 litre pressure tank for automatic operation. Its high-head SW77 injector works with the jet and venturi design to maximize discharge pressure while purging air. The 35 litre tank provides 10.8 litres of draw-off, delaying pump starts for small demands and reducing overall energy consumption.\u003c\/p\u003e \u003cp\u003eConstruction includes a solid cast iron body and a double race bearing system designed for mechanical strength and longevity. The Type D mechanical switch contains no sensitive electronics, providing high resistance to lightning strikes and power surges common in remote agricultural areas. The assembly handles liquids up to 65°C and includes a 2-year manufacturer warranty.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eSolid cast iron construction ensures the system remains a durable fixture in harsh outdoor agricultural and farm environments.\u003c\/li\u003e \u003cli\u003eIntegrated 35 litre pressure tank provides approximately 10.8 litres of draw-off to reduce 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 site duty.\u003c\/li\u003e \u003cli\u003eType D mechanical switch with heavy-duty relay points provides dependable automatic operation in areas with fluctuating power.\u003c\/li\u003e \u003cli\u003eSW77 injector configuration is tuned to deliver high discharge pressure for site distribution.\u003c\/li\u003e \u003cli\u003eDouble race bearing technology effectively manages axial and radial forces to extend the service life of the motor.\u003c\/li\u003e \u003cli\u003eCorrosion-resistant stainless steel shaft and TEFC housing protect the internal components from environmental moisture and vermin.\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":50957416562935,"sku":"CJ850-1P-SW77-T35","price":2651.3,"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-35l-tank.png?v=1784703598","url":"https:\/\/foundationpumps.com.au\/products\/orange-pumps-cj850-sw77-shallow-well-pressure-pump-high-static-head-35l-tank","provider":"Foundation Pumps","version":"1.0","type":"link"}
