Using the large 50 mm\/40 mm pipe class, it minimises friction at these volumes for maximum throughput with three-phase efficiency.\u003c\/p\u003e \u003cp\u003eHead reaches 53 m at 10 m suction. The three-phase 2.4 kW \/ 415V motor draws 5 Amps per phase — a fraction of the 14.1 Amps the single-phase equivalent requires — supporting demanding high-volume duties with efficient operation.\u003c\/p\u003e \u003cp\u003eThe injector sits down the bore, keeping moving parts and electricity above ground. Thermoplastic injector resists salt, hardness and iron. At this flow rate the smooth internal bore keeps turbulence low. The jet and venturi are matched to bore yield. An optional Offset Flange (101431, 1½ x 1½ inch female thread) allows installation away from the bore to access water above flood level or closer to electricity.\u003c\/p\u003e \u003cp\u003eThe pump features a cast iron body, stainless steel shaft, double race bearings and a carbon ceramic mechanical seal. The TEFC motor includes thermal overload protection and handles liquid temperatures up to 65°C. Supplied with the dedicated WK-CJ850 water kit assembled and glued, including a 60 litre tank with 20 litre draw-off. A 2-year warranty applies; loss-of-prime switch optional.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eDW79-20 injector with 50 mm suction and 40 mm discharge pipework.\u003c\/li\u003e \u003cli\u003eThree-phase 2.4 kW \/ 415V motor draws 5 Amps per phase.\u003c\/li\u003e \u003cli\u003eThermoplastic injector tolerates salt, hard water and iron.\u003c\/li\u003e \u003cli\u003eSmooth injector bore reduces turbulence at maximum flow.\u003c\/li\u003e \u003cli\u003eNo moving parts or electricity down the bore.\u003c\/li\u003e \u003cli\u003eJet and venturi matched to available groundwater yield.\u003c\/li\u003e \u003cli\u003eCast iron pump body with stainless steel motor shaft.\u003c\/li\u003e \u003cli\u003eDouble race bearings with carbon ceramic mechanical seal.\u003c\/li\u003e \u003cli\u003eTEFC motor with thermal overload protection.\u003c\/li\u003e \u003cli\u003eSuitable for liquid temperatures up to 65°C.\u003c\/li\u003e \u003cli\u003eWK-CJ850 water kit supplied assembled and glued.\u003c\/li\u003e \u003cli\u003eIncludes pressure gauge, brass 5-way tee, gate valve and stainless steel barrel union.\u003c\/li\u003e \u003c\/ul\u003e","brand":"Orange Pumps","offers":[{"title":"Default Title","offer_id":50962918899959,"sku":"CJ850-3P-DW79-20","price":2351.4,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/orange-pumps-cj850-dw79-20-three-phase-deep-well-jet-pump-irrigation-venturi.png?v=1784798252","url":"https:\/\/foundationpumps.com.au\/products\/orange-pumps-cj850-dw79-20-three-phase-deep-well-jet-pump-irrigation-venturi","provider":"Foundation Pumps","version":"1.0","type":"link"}
