Part of the IntelliMaster range, it delivers intelligent pressure control with energy-efficient operation and consistent water supply.\u003c\/p\u003e\n\u003cp\u003eConstructed with a 304 stainless steel wet end, including pump casing, impellers, and hydraulic components, the IMH1100K offers excellent corrosion resistance and durability. The closed impeller multistage design ensures efficient pressure generation and smooth water flow for reliable performance.\u003c\/p\u003e\n\u003cp\u003eThe pump delivers a maximum head of 59 metres and a maximum flow of approximately 150 L\/Min under practical operating conditions. Integrated with a variable frequency drive (VFD), it automatically adjusts motor speed to maintain constant pressure while improving system efficiency and reducing energy consumption.\u003c\/p\u003e\n\u003cp\u003eSupplied as a complete system, the unit includes an integrated VFD controller, stainless steel five-way tee with non-return valve, pressure transducer, and an 8 litre pressure tank for stable pressure operation. Powered by a TEFC motor with IP55 protection and inbuilt thermal overload, the pump is suitable for clean water applications with a maximum liquid temperature of 40°C. :contentReference[oaicite:0]{index=0}\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eVariable speed multistage centrifugal pump system\u003c\/li\u003e\n\u003cli\u003eIntegrated variable frequency drive (VFD)\u003c\/li\u003e\n\u003cli\u003e304 stainless steel wet end construction\u003c\/li\u003e\n\u003cli\u003eClosed impeller multistage design\u003c\/li\u003e\n\u003cli\u003eMaximum head: 59 m\u003c\/li\u003e\n\u003cli\u003eMaximum flow: approx. 150 L\/Min*\u003c\/li\u003e\n\u003cli\u003eIncludes 8 litre pressure tank\u003c\/li\u003e\n\u003cli\u003ePressure transducer and stainless steel five-way tee\u003c\/li\u003e\n\u003cli\u003eBuilt-in non-return valve\u003c\/li\u003e\n\u003cli\u003eLarge LCD display with adjustable pressure settings\u003c\/li\u003e\n\u003cli\u003eTEFC motor with IP55 protection\u003c\/li\u003e\n\u003cli\u003eInbuilt thermal overload protection\u003c\/li\u003e\n\u003cli\u003eSuitable for domestic pressure boosting and irrigation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Onga","offers":[{"title":"Default Title","offer_id":50698738303223,"sku":"IMH1100K","price":2210.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/IMHSeries_IMH750_IMH1100_IMH2200Pump.png?v=1776678479","url":"https:\/\/foundationpumps.com.au\/products\/onga-imh1100k-stainless-steel-variable-speed-multistage-irrigation-pump-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
