It features a factory-fitted pressure switch that enables automatic start\/stop functionality based on system demand. The unit is optimized for clean water transfer to maintain steady pressure at the outlet from tanks or bores.\u003c\/p\u003e \u003cp\u003eHydraulic performance includes a maximum head of 47 m and a maximum flow rate of 100 L\/Min. The 1.1 kW single-phase motor operates on 240v and draws 7 Amps. This performance is ideal for systems where automatic pressure management is required for washdown, agriculture, and horticulture. The integrated pressure switch provides automatic start and stop based on system pressure.\u003c\/p\u003e \u003cp\u003eThe hydraulic design utilizes high efficiency twin brass impellers to build pressure through two centrifugal stages for efficient transfer. This twin-stage centrifugal approach provides significant head while remaining quiet during operation. The system is designed to handle clean liquid temperatures ranging from 0°C to +90°C, making it suitable for temperate water distribution.\u003c\/p\u003e \u003cp\u003eConstruction includes a rugged cast iron pump body and a stainless steel shaft for long-term structural integrity. The high-quality Ceramic\/Graphite\/NBR mechanical seal ensures a watertight environment, while the IP44 TEFC motor provides protection against environmental conditions. The pressure switch provides automatic start and stop based on system pressure.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eAutomatic centrifugal pressure system featuring an integrated pressure switch for self-managing water distribution and boosting.\u003c\/li\u003e \u003cli\u003eRugged cast iron pump body provides superior structural durability and protection for the internal hydraulic components.\u003c\/li\u003e \u003cli\u003eHigh-efficiency twin brass impellers offer dual-stage pressure boosting for consistent water delivery in high-head applications.\u003c\/li\u003e \u003cli\u003ePremium Ceramic\/Graphite\/NBR mechanical shaft seal prevents internal leaks and ensures a long operational service life.\u003c\/li\u003e \u003cli\u003eReliable 240V single-phase TEFC induction motor rated at IP44 for safe 50Hz operation in domestic and civil environments.\u003c\/li\u003e \u003cli\u003eStainless steel motor shaft provides the strength and corrosion resistance needed for continuous automatic water transfer.\u003c\/li\u003e \u003cli\u003eThreaded 32mm suction and 25mm discharge connections facilitate straightforward integration into existing pressurized water networks.\u003c\/li\u003e \u003cli\u003eComplete automatic solution supplied with a 1.5m power lead and 3-pin plug for rapid installation and immediate service.\u003c\/li\u003e \u003c\/ul\u003e","brand":"Onga","offers":[{"title":"Default Title","offer_id":50953200894199,"sku":"SPN100SP","price":1756.05,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/onga-spn100sp-pressure-switch-centrifugal-pump-automatic-pressure-boosting-twin-impeller.png?v=1784546451","url":"https:\/\/foundationpumps.com.au\/products\/onga-spn100sp-pressure-switch-centrifugal-pump-automatic-pressure-boosting-twin-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
