This packaged system is intended for residential and light commercial installations where reduced pump cycling is desirable.\u003c\/p\u003e\u003cp\u003eThe AISI 304 stainless steel pump body and impellers deliver a maximum head of approximately 20.9 metres and a maximum flow rate of 142 litres per minute. The 0.5 kW motor operates on 220–240 V single-phase, drawing 2.8 Amps. Suction is Rp 32 mm and discharge is Rp 25 mm. The pump handles clean liquids up to 60°C.\u003c\/p\u003e\u003cp\u003eThe 18-litre pressure vessel provides additional water storage, reducing pump starts during low-demand operation. The mechanical seal is ceramic, carbon, and EPDM. The motor is rated IP55 with Class F insulation. Thermal protection is provided by an automatic reset overload device. The horizontal configuration is designed for floor mounting.\u003c\/p\u003e\u003cp\u003eInstallation requires a level, frost-protected surface with adequate ventilation. The pre-wired terminal junction box simplifies electrical connection. The pump is certified for drinking water use under WRAS and ACS. The stainless steel hydraulic components and larger pressure vessel make this variant suited to demanding residential applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAISI 304 stainless steel pump body and impellers for corrosion resistance.\u003c\/li\u003e\n\u003cli\u003eRp 32 mm suction and Rp 25 mm discharge connections for higher flow capacity.\u003c\/li\u003e\n\u003cli\u003e18-litre APT pressure vessel provides increased water storage for reduced cycling.\u003c\/li\u003e\n\u003cli\u003eIP55 motor enclosure protects against dust and moisture ingress.\u003c\/li\u003e\n\u003cli\u003eWRAS and ACS certification for drinking water use.\u003c\/li\u003e\n\u003cli\u003eAutomatic reset thermal protection incorporated into the motor.\u003c\/li\u003e\n\u003cli\u003eClose-coupled design minimises installation space requirements.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":51073929838839,"sku":"5HM03S-PT18","price":1663.64,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-5hm03s-pt18-stainless-steel-multistage-pressure-pump-light-pressurisation-18-litre-tank.png?v=1787830682","url":"https:\/\/foundationpumps.com.au\/products\/lowara-5hm03s-pt18-stainless-steel-multistage-pressure-pump-light-pressurisation-18-litre-tank","provider":"Foundation Pumps","version":"1.0","type":"link"}
