PondMAX PU pumps move freshwater pond water through external biological filters, waterfalls and watercourses. Maximum flows range from 3,600L/h on PU3500 to 17,000L/h on PU17000. The intake cage and open-vane impeller pass soft pond debris up to 6mm, helping carry it to a separate filter.
A ceramic shaft supports the open-vane impeller, and the cage opens without tools for maintenance. Soft start brings the rotor up to speed gradually. Anti-jam electronics interrupt a stalled rotor and attempt restarts; if the obstruction remains, switch off the pump and clear it before restarting.
Install the pump fully submerged on a raised, stable surface clear of bottom sludge. Choose pipework with enough capacity for the required flow and allow for lift, bends and friction losses.
Maximum flow and maximum head are separate limits. Lift and resistance in hoses, bends and fittings reduce the flow delivered at the outlet.
PU3500 to PU12500: maintain at least half the maximum flow through the pump for motor cooling.
Three-year manufacturer warranty, subject to Aquatec Equipment terms. Retain proof of purchase; consumable impeller parts are excluded.
