Pond Pump
Pontec PondoMax Eco 3500
Model: PondoMax Eco 3500
A submersible Pontec pond pump for watercourses, waterfalls and filtration. Manufacturer documents show conflicting Qmax/Hmax/power figures; see limitations.
About Pontec PondoMax Eco 3500
The Pontec PondoMax Eco 3500 is a submersible pond pump sold for watercourses, waterfalls and filtration tasks. Pontec’s own product literature and the official operating instructions identify this unit (product code 54771) as a member of the PondoMax Eco family and state that it is suitable for solid handling and submersible operation. The pump is supplied with a stepped hose adapter (to be shortened to the hose size in use) and uses threaded inlet/outlet connections as specified by Pontec. The manufacturer documents used for this record contain some conflicting numeric entries for the same model: the sales brochure gives one set of flow, head and power figures while the official manual gives slightly different figures. Because both values appear in first‑party Pontec material and no single reconciled figure is provided, the numeric fields for maximum flow, maximum head and power are left null here — those differences are explained in Limitations. Confirmed, consistent details from Pontec include a 10 m supply cable, inlet/outlet thread sizes, a stated weight of 3.1 kg, listed dimensions in the sales folder, submersible depth limit of 4 m and an allowable water temperature range of +4 to +35 °C. Pontec also documents a 3‑year guarantee against manufacturing faults (wear parts excluded) in the operating instructions. This entry is constructed only from the verified Pontec documents cited in the research notes. It does not attempt to reconcile conflicting Pontec statements or infer unstated performance points such as flow‑at‑head curves, IP rating numbers, or pond capacities for fish or koi.
Best for
Garden watercourses, waterfalls and basic pond filtration; handling small solids (manufacturer states 4–8 mm).
Things to consider
Pontec’s own documents contain conflicting values for maximum flow, maximum head and electrical power for this exact model: the sales folder lists 3600 l/h, Hmax 2.20 m and 45 W, while the operating instructions list ≤3500 l/h, ≤2.4 m Hmax and 40 W. Because both are first‑party Pontec sources and no single reconciled figure is provided, the Qmax/Hmax/power fields are left null here. There is also a minor dimensional discrepancy between Pontec documents (280 x 235 x 150 mm vs 280 x 230 x 150 mm). Pontec does not publish an IP code, pump performance curve (flow at head points), or manufacturer‑stated pond/fish/koi capacities for this standalone pump in the examined documents; those fields are therefore not supplied. The pump is a standalone unit (no UVC/filter media integrated).
Installation
Manufacturer documents state the unit is submersible to 4 m and should be removed if frost is expected. Water temperature limits are +4 … +35 °C. The unit is supplied with a stepped hose adapter that must be fitted to the outlet and shortened to the hose diameter used. Inlet/outlet threads are G1 and G1½. A 10 m cable is supplied. Pontec warns not to operate the pump from a dimmer.
Maintenance
Pontec operating instructions describe a 3‑year guarantee against proven material and manufacturing faults (wear parts excluded) and outline conditions for claims. Follow the manufacturer manual for recommended maintenance procedures (refer to Pontec documentation).
Safety
Do not operate the pump from a dimmer. Observe the water temperature limits (+4 … +35 °C). Remove the pump if frost is expected. The manual describes the unit as dust tight and submersible to the stated depth — follow the operating instructions for safe use.
