Description
The Oase AquaMax Eco Premium 2500 (Item 87581) is a compact, synchronous electronic pond pump delivering 2,500 GPH at 60 watts — engineered with Pulse 6 technology, the latest generation motor design that provides 35% greater efficiency than the previous Eco model. The patented Seasonal Flow Control (SFC) automatically reduces flow and wattage by up to 50% as water temperatures drop in fall and winter, maintaining healthy pond circulation while dramatically lowering operating costs. The Environmental Function Control (EFC) shuts the pump off automatically if run dry or blocked, and an integrated grounding plate protects against stray current. A secondary OC (Optional Connection) port allows a satellite filter or surface skimmer to be connected as a second suction point, with a mechanical regulator adjusting suction balance from 0–100%. Handles solids up to 0.375” (3/8”). Frost-proof to −4°F for year-round in-pond installation. Can be used submersed or inline. 5-Year warranty (3+2 with registration). Made in Germany. GFCI-protected outlet required. Not for use in pools or salt water.
Why Choose the Oase AquaMax Eco Premium 2500?
- Pulse 6 synchronous electronic motor — 35% more efficient: The AquaMax Eco Premium 2500 uses a synchronous electronic motor with Pulse 6 technology, featuring more magnets and less vibration than the previous Eco generation. Synchronous motors run without slip and are more efficient across all operating speeds — the foundation that makes SFC energy savings possible. This is 35% more efficient than the prior Eco model.
- Seasonal Flow Control (SFC) — up to 50% energy reduction: As pond water temperature drops in fall and winter, fish metabolism slows and filtration demand decreases. SFC automatically senses temperature and reduces the pump’s flow and wattage by up to 50%, maintaining circulation and biological filter function while halving operating costs during low-demand months. Flow increases automatically as water warms in spring — zero manual adjustment required.
- EFC + integrated grounding plate — dual safety systems: Environmental Function Control (EFC) monitors pump conditions and shuts down automatically if run dry or if debris causes a blockage, preventing motor burnout. Separately, an integrated grounding plate within the pump body dissipates stray electrical current into the ground before it can reach pond water — important for fish health and human safety in a body of water.
- OC port secondary intake — one pump, two suction zones: The OC (Optional Connection) port on the pump body accepts a second inlet connection for an AquaMax Satellite Filter or surface skimmer. A mechanical suction regulator lets you balance primary and secondary suction from 0–100%, allowing a single pump to simultaneously pull water from the pond bottom and skim the surface.
- 0.375” (3/8”) solids handling: The large-surface, wrap-around pre-filter screen is designed to pass coarse debris particles — fish waste, decaying vegetation, leaves — directly through to the filtration system rather than trapping them at the pump. Fewer clogs, fewer maintenance interventions, better biological filtration.
- Inline or submersible installation: For submersed use, install in the pond with the wrap-around pre-filter in place. For inline use outside the pond, remove the pre-filter and secure the pump body with the included mounting bracket. The Sch40 adapter allows direct connection to standard rigid PVC plumbing without additional fittings.
- Frost-proof to −4°F — year-round installation: Patented frost protection technology allows the pump to remain in the pond through winter without removal, even when temperatures drop well below freezing.
- Optional Oase Eco Control and Garden Cloud Controller compatible: The AquaMax Eco Premium 2500 can be connected to the optional Oase Eco Control unit or Garden Cloud Controller for remote monitoring, smart scheduling, and digital flow adjustment — compatible with Oase’s full connected pond management ecosystem.
- Oase Clear Water Guarantee eligible: When properly sized, paired with an appropriately matched Oase filter and UV clarifier, and registered online, this pump qualifies for the Oase Clear Water Guarantee — clear water visible to 3 feet depth, guaranteed.

Frequently Asked Questions
How does pump flow drop with head height on the 2500?
The AquaMax Eco Premium 2500 is rated at 2,500 GPH open flow. Flow decreases as head height (the vertical lift from pump to waterfall or filter outlet) increases. Oase publishes a model-specific performance curve for the 2500 (Item 87581) showing the pressure/flow relationship at each foot of head. For the specific GPH values at 5, 8, and 10 feet of head, refer to the Oase AquaMax Eco Premium 2500 pressure chart or call (765) 508-4352 for help matching this pump to your waterfall or filter height.
What is Seasonal Flow Control (SFC) and how much energy does it save?
Seasonal Flow Control (SFC) is a patented Oase technology that automatically monitors pond water temperature and adjusts the pump’s flow rate and wattage in response. As water temperatures fall in autumn and winter, SFC reduces pump output — slowing flow and cutting wattage by up to 50% compared to full summer operation.
The logic mirrors the pond’s biology: fish metabolism slows significantly in cold water, producing less waste and requiring less filtration turnover. SFC matches pump output to actual pond demand rather than running at full capacity year-round. When water warms in spring, flow automatically increases without any manual adjustment. The 2500 at 60W running reduced SFC operation during winter months can cut annual electricity costs substantially for continuous-run installations.
How does the secondary OC port and suction regulator work?
The AquaMax Eco Premium 2500 features an OC (Optional Connection) port — a second intake connection on the pump body. This port can be connected to an AquaMax Satellite Filter or an in-pond skimmer, allowing a single pump to draw water simultaneously from two locations in the pond.
A mechanical suction regulator on the OC port allows you to adjust the split between primary and secondary suction from 0% to 100%. For example: 70% primary intake / 30% satellite = prioritizing main body circulation while still pulling surface water. The regulator turns by hand and holds its position without tools.
This lets you address dead spots, stagnant corners, or surface debris without adding a second pump to the system — an efficiency advantage that reduces both equipment cost and electrical draw.
Does the AquaMax Eco Premium 2500 have dry-run protection?
Yes. The pump features Environmental Function Control (EFC), an internal sensor that monitors water flow through the pump. If EFC detects that the pump is running dry — for example, if water level drops below the pump intake, or if a blockage stops water flow — it automatically shuts the pump off to prevent motor damage from overheating.
Once the cause is resolved (water level restored, blockage cleared), the pump can be restarted normally. EFC is a passive protection system that runs continuously during operation without any configuration required.
Can the AquaMax Eco Premium 2500 stay in the pond during winter?
Yes. The pump features patented frost protection technology that safeguards the internal components from freeze damage down to −4°F, as long as the pump remains submerged in water. Ice will form on the pond surface, but the pump body in the water is protected.
Leaving the pump running through winter maintains a small area of open water at the surface, which allows gas exchange for koi and other fish. Seasonal Flow Control automatically reduces energy use during cold months, making continuous year-round operation economical.
How do I qualify for the 5-year warranty?
The AquaMax Eco Premium 2500 includes a 3-year manufacturer’s warranty as standard. To extend to the full 5-year warranty (3+2), register the product online with Oase North America within the specified registration window after purchase. The extra 2-year extension is activated through product registration — no additional cost.
When the pump is properly sized, paired with an appropriately matched Oase filter and UV clarifier, and registered, it also qualifies for the Oase Clear Water Guarantee — Oase’s assurance of clear water visible to 3 feet depth in your pond.
