Divertron 900 60209373 without float

The DAB Divertron 900 is a submersible multi-impeller booster pump with fully integrated electronics, designed for clean water pressurisation, garden irrigation and rainwater reuse. It drops into a well, tank, cistern or borehole chamber and provides automatic on-demand pressure to taps, sprinklers and non-potable household feeds.

This is the standard-bodied, non-float variant (DAB part 60209373). It uses the pump’s built-in electronic dry-run protection rather than a physical float switch — the right choice where the water level is reliable and a float isn’t needed or wanted.

At a glance

Built for

Rainwater harvesting tanks supplying outside taps, garden irrigation lines and WC/washing-machine feeds. Private well and borehole supply where pressure needs lifting to the house. Garden and allotment irrigation with sprinklers, soaker hoses or drip lines. Emergency or seasonal water transfer from rivers, ponds or storage cisterns.

The 900 is the higher-pressure model in the Divertron range. Specify it where the rise from pump to highest tap exceeds about 13 m, where pipe runs are long, or where you want firm pressure at multiple outlets.

How the automatic operation works

The Divertron has an integrated pressure switch and flow sensor. Open a tap, system pressure drops below the 2.4 bar cut-in, the pump starts. Close the tap, flow stops, the pump shuts off after a 10-second delay. No external pressure switch, no separate controller, no manual priming once installed.

Dry-run protection is built in: if no flow or pressure is detected for 20 seconds the pump goes into DRYRUN alarm and shuts down, then attempts a controlled restart sequence (after 1 hour, then 5 hours, then every 24 hours) until water is detected again. An anti-flood routine cuts the motor every 60 minutes during continuous running to verify the non-return valve is sealing correctly.

All electronics sit inside the pump body. Quick-access cover for the starting capacitor compartment if servicing is ever required.

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). 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

Pump must remain submerged with at least 50 mm of water above it for motor cooling. In a well, suspend at least 1 metre above the bottom to avoid drawing in sand and sediment — use rigid metal pipe to support and bracket at the wellhead, not the cable or the handle. In a tank, the chamber must be at least 160 mm in diameter to clear the pump body.

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 (e.g. a WC fill cycle) and reduce motor cycling.

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 the pump for winter storage if the chamber may freeze.
