The Ultra IV uses a variable speed drive to modulate motor speed continuously — maintaining consistent pressure without the on\/off cycling. This means steadier pressure, quieter operation, and less wear on the pump and pipework.\u003c\/p\u003e\n\n\u003ch3\u003eIs it suitable for tank water?\u003c\/h3\u003e\n\u003cp\u003eYes — tank water supply is one of the primary applications. The suction lift is up to 1.5m, so the pump needs to be positioned close to the tank water level. For tanks significantly below the pump, get in touch to confirm whether the installation suits the suction lift specification.\u003c\/p\u003e\n\n\u003ch3\u003eDoes it come complete?\u003c\/h3\u003e\n\u003cp\u003eYes — the pump, integrated variable speed controller, and pressure tank are all included. Connect to your supply pipework and it's ready to go.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the IP54 rating?\u003c\/h3\u003e\n\u003cp\u003eIP54 means the pump is protected against dust ingress and water splashing from any direction. It's suitable for pump shed and outdoor installations in normal conditions, but should not be submerged or exposed to heavy water spray.\u003c\/p\u003e\n\n\u003ch3\u003eDoes it need a plumber to install?\u003c\/h3\u003e\n\u003cp\u003eYes — professional installation by a licensed plumber is recommended. The pump connects via standard 1\" BSP fittings and needs to be correctly integrated with your tank supply and pressure system.\u003c\/p\u003e\n\n\u003ch3\u003eCan I pair it with a water filter?\u003c\/h3\u003e\n\u003cp\u003eYes. A filter installed upstream protects the pump from sediment and extends its service life. Get in touch for filter recommendations suited to your water source.\u003c\/p\u003e\n\n\u003ch3\u003eWhat warranty applies?\u003c\/h3\u003e\n\u003cp\u003e3 years, backed by Waimana Water.\u003c\/p\u003e","brand":"Waimana Water","offers":[{"title":"Default Title","offer_id":45557705408556,"sku":"Kaha Ultra IV","price":2297.7,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0623\/5966\/6732\/files\/KahaUltraIVangledplainbackground.jpg?v=1779309800","url":"https:\/\/www.filtrationstation.co.nz\/products\/waimana-kaha-ultra-iv-variable-speed-pressure-pump","provider":"Filtration Station NZ","version":"1.0","type":"link"}
