It suits sump emptying, lawn and garden irrigation, and low-head drainage applications. The pump sits submerged in the water it's draining — when the water level rises, the float switch starts the pump automatically, and it stops again once the level drops to the safe operating point.\u003c\/p\u003e\n\n\u003cp\u003eThe D23A\/B uses a multi-stage 3-impeller centrifugal design for low-flow high-head performance, with 304 stainless steel shaft, motor shell, and fasteners throughout.

As the water level rises, the float switch lifts with it. At the trigger point, the pump starts automatically, drawing water in through the bottom strainer and pushing it up through the 1\" outlet to the discharge point. Once the level drops to the pump's safe operating level, the float falls and the pump shuts off.

As the water level rises in the sump or pit, the float lifts with it. When it reaches the trigger point, the pump switches on and starts draining the water. Once the level drops far enough, the float falls and the pump switches off automatically. No manual switching required.\u003c\/p\u003e\n\n\u003ch3\u003eHow deep can the pump be submerged?\u003c\/h3\u003e\n\u003cp\u003eThe D23A\/B can be submerged to a maximum of 7 metres.

The \"X\" indicates no specific dust ingress rating has been assigned, and the \"8\" indicates it is rated for permanent submersion beyond 1 metre.\u003c\/p\u003e\n\n\u003ch3\u003eWhat size discharge pipe does it need?\u003c\/h3\u003e\n\u003cp\u003eThe outlet is 1\" BSP female.

It can handle water containing up to 1% small solids with a minimum soft solid size of 1mm O.D. Do not pump abrasive materials such as sand or grit — these will accelerate wear and shorten pump life.\u003c\/p\u003e\n\n\u003ch3\u003eCan I use it in my garden for irrigation?\u003c\/h3\u003e\n\u003cp\u003eYes. The D23A\/B is suited to garden and lawn irrigation at low to medium heads. With a maximum head of 22.5m, it can push water to elevated outlets or across longer runs.\u003c\/p\u003e\n\n\u003ch3\u003eCan I install it myself?\u003c\/h3\u003e\n\u003cp\u003eLowering the pump into a sump and connecting to discharge pipework is straightforward for a confident DIY installer. Make sure there is enough room for the float switch to rise and fall freely — if the float is restricted, the pump may not operate correctly. For installations involving electrical work, get a professional involved. If you're unsure, get in touch and we'll help.\u003c\/p\u003e\n\n\u003ch3\u003eWhat maintenance does it need?\u003c\/h3\u003e\n\u003cp\u003eInspect the pump every 6 months. Keep it clean — lint, hair, and fibrous material can bind around the shaft. Always position and retrieve the pump using a rope — never lift or lower it by the power lead as this can damage the cable entry seals.\u003c\/p\u003e\n\n\u003ch3\u003eWhat warranty applies?\u003c\/h3\u003e\n\u003cp\u003eThe Davey D23A\/B carries a 2-year warranty.\u003c\/p\u003e","brand":"Davey","offers":[{"title":"Default Title","offer_id":45576383201324,"sku":"D23A\/B","price":808.45,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0623\/5966\/6732\/files\/D23AB-High-Pressure-Drainage-pump-1024x777_png_d91cef6b-a94b-4b55-8eb6-a85a899fa433.webp?v=1779933748","url":"https:\/\/www.filtrationstation.co.nz\/products\/davey-d23ab-submersible-sump-pump","provider":"Filtration Station NZ","version":"1.0","type":"link"}
