Aquascape SLD 20000-40000 Adjustable Flow Pond Pump

The SLD 20000-40000 Adjustable Flow Pond Pump is a professional-grade, submersible pump made for continuous use in ponds, Pondless® Waterfalls, and other water feature applications. Solids-handling, asynchronous motor technology provides superior reliability, reduced maintenance, and a maximum flow rate of 37 800 litres per hour. The design allows the pump to handle solids effectively, resulting in less maintenance and trouble-free performance. The included Smart Pump Receiver features an integrated control panel and makes it easy to control your pump with the Aquascape Smart Control App, including flow adjustment and customised scheduling.

An optional Universal Remote for Adjustable Flow Pumps (Item #45041) is available separately to allow wireless control without the use of a smartphone or tablet. The pump is also backed by a limited 3-year warranty, ensuring years of reliable use. NOTE: Avoid leaving the receiver in direct sunlight. We recommend installing in a cool, shaded area, if possible.

Choosing the right pump for the job

Use the flow at the actual operating head, not the headline maximum-flow figure. Vertical lift, pipe length, fittings and connected filtration all reduce delivered flow. Use the largest practical pipe bore, provide isolation for servicing and check whether the selected model is approved for submerged, external or both installation methods.

Our practical advice: If you are unsure about sizing or compatibility, send us the Aquascape part numbers you already have and a photograph or sketch of the installation. We will help check the combination before dispatch.
