About AquaForte DM-20000 Vario
The AquaForte DM-20000 Vario (RD762) is a variable/adjustable pond pump from AquaForte's DM‑Vario series. According to the AquaForte product catalogue, the model supports a manufacturer-stated maximum flow of 20 m³/h (20,000 L/h) and a maximum head of 6.5 m. The product is supplied with a manufacturer-listed electrical power range of 34–187 W, which indicates the pump operates with variable power rather than a single fixed wattage. The DM‑20000 entry in AquaForte materials shows 2" inlet and outlet fittings. AquaForte documentation for the DM‑Vario series describes this family as adjustable via an external controller, with flow control between 30% and 100%. The controller can start and stop the pump and the series includes automatic dry‑run protection (the pump will cut power when insufficient water is detected). The brochure indicates the DM‑Vario pumps are suitable for both wet and dry installations and for outdoor use. The RD762 entry in the official AquaForte catalogue is focused on performance figures and control features. The pump is presented as a controllable power/flow device for pond systems; it is a pump-only product (no UV is listed in the AquaForte entry). Several installation and physical details commonly sought by pond owners — for example cable length, IP rating, physical dimensions, weight, and manufacturer-stated pond/fish/koi capacity figures — are not provided for RD762 in the AquaForte materials reviewed.
Best for
