Divertron 900 X 60208443

The DAB Divertron 900 X is a submersible multi-impeller booster pump with fully integrated electronics, configured for installations with sediment or particulates at the base of the water source. The X variant uses a closed filter base with a 1″ female threaded inlet, designed to be paired with the separately supplied KIT X floating suction kit.

Instead of drawing water through the bottom of the pump, the KIT X attaches a flexible suction line to a buoyant float — water is drawn from just below the surface, well above the sediment layer that settles at the base of wells and rainwater tanks. The result is a cleaner supply, less filter blockage, and reduced wear on the pump internals. This is the higher-pressure 900 model, with 45 m max head. DAB part 60208443.

At a glance

Built for

Two-storey domestic feeds from rainwater tanks with sediment at the base. Wells with sand, silt or organic debris where you also need pressure for a longer pipe run or higher tap. Boreholes and stored water sources where the bottom 100–200 mm is best left undisturbed and the rise to the highest outlet exceeds 13 m.

Performance and electronics are the same as the standard 900 — 45 m head, 6 m³/h flow, 0.75 kW motor, 2.4 bar cut-in. The difference is purely in how the water enters the pump.

How the X system works

The pump base is closed and watertight, with a 1″ female threaded connection. The KIT X (sold separately) attaches a flexible hose with a buoyant float at the far end. Once installed, the float sits on the water surface, with the suction intake hanging just below it — typically 100–200 mm down. As the water level rises and falls, the float follows, always drawing from the same shallow zone above the sediment.

The pump itself can be positioned out of the water — on a platform alongside the tank, or on the wellhead. This is a useful flexibility advantage on installations where access for maintenance matters.

Build

Pump body and impellers in technopolymer for corrosion and oxidation resistance. Stainless steel motor shaft (AISI 416 + AISI 304) and motor cap (AISI 304). Brass insert at the X inlet for the threaded connection. EPDM seals throughout. Carbon-impregnated resin / ceramic / NBR mechanical seal. Integrated non-return valve in the discharge.

IP68 rated motor with class F insulation, asynchronous design with integrated thermal overload protection. Supplied with 15 m H07RNF power cable and Schuko plug.

Installation notes

The X version requires the KIT X floating suction kit to function as designed — without it, the closed inlet base means the pump cannot draw water. We supply the KIT X separately; check the accessories section before checkout, or get in touch if you’d like both bundled.

The 1″ threaded discharge is supplied with a four-section fitting-reducer. Use 1″ pipework as a minimum to preserve performance. Do not fit a separate non-return valve within 1 m of the pump discharge — the integrated valve handles this. A small 0.5–2 litre auxiliary expansion tank on the delivery side is recommended to absorb short draw-offs.

Recommended maximum vertical lift to the highest tap is 20 m. Maximum 20 starts per hour. Install in a location not exposed to freezing, or remove and drain for winter storage if the chamber may freeze.
