Larger 50 mm suction and 40 mm discharge pipework reduces friction losses at the flow rates this configuration is designed to produce.\u003c\/p\u003e \u003cp\u003eAt 10 m suction it delivers 130 L\/Min — matching the CJ650's large-port injector output but backed by more head, reaching 52 m at reduced flow. The 1.5 kW \/ 240V motor draws 9.7 Amps, supporting demanding irrigation applications where coverage area and throughput are essential.\u003c\/p\u003e \u003cp\u003eThe thermoplastic DW57-20 injector sits down the bore rather than at the pump. It resists salt, hardness and iron, with a smooth internal bore that keeps turbulence low at high flow rates. 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 WK-CJ30-50 water kit assembled and glued, including a 35 litre tank with 11.7 litre draw-off. A 2-year warranty is standard; loss-of-prime switch optional.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eDW57-20 injector with 50 mm suction and 40 mm discharge pipework.\u003c\/li\u003e \u003cli\u003eThermoplastic injector tolerates salt, hard water and iron.\u003c\/li\u003e \u003cli\u003eSmooth injector bore reduces turbulence at high flow rates.\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-CJ30-50 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 \u003cli\u003e35 litre tank with 11.7 litre draw-off and 30-50 psi switch setting.\u003c\/li\u003e \u003c\/ul\u003e","brand":"Orange Pumps","offers":[{"title":"Default Title","offer_id":50962917130487,"sku":"CJ750-1P-DW57-20","price":1898.9,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/orange-pumps-cj750-dw57-20-high-volume-deep-well-jet-pump-farm-irrigation-venturi.png?v=1784798224","url":"https:\/\/foundationpumps.com.au\/products\/orange-pumps-cj750-dw57-20-high-volume-deep-well-jet-pump-farm-irrigation-venturi","provider":"Foundation Pumps","version":"1.0","type":"link"}
