Description

Oase AquaMax Eco Expert 21000 Pond Pump

The Oase AquaMax Eco Expert 21000 Pond Pump is a powerful, electronically controllable filter and watercourse pump designed for demanding pond filtration systems, large waterfalls and high-flow installations.

Delivering up to 21,000 litres per hour with a maximum head height of 8 metres, it combines substantial pumping performance with intelligent control and energy-saving features. The pump can be installed submerged or dry, making it particularly versatile when designing larger pond and koi filtration systems.

Oase AquaMax Eco Expert 21000 for Demanding Pond Systems

With a maximum flow of 21,000lph, the AquaMax Eco Expert 21000 is designed for installations where a conventional pond pump may not provide sufficient performance.

It’s particularly well suited to larger filtration systems, substantial watercourses and waterfalls, with its 8m maximum head providing considerably more pressure capability than many standard filter pumps.

Handles Solids up to 11mm

The pump can pass debris particles measuring up to 11mm, allowing leaves, fish waste and other suspended material to be transported towards the pond filter rather than simply collecting around the pump.

Its large 1,060cm² filter intake surface helps provide plenty of water intake area when the pump is installed submerged.

Adjustable Performance & Seasonal Flow Control

Pump output can be electronically adjusted, allowing performance to be better matched to the requirements of the filtration system or water feature.

Oase’s Seasonal Flow Control (SFC) can also adapt operation according to water temperature, reducing unnecessary pumping performance and energy consumption when full output isn’t required.

OASE Control Compatible

The AquaMax Eco Expert 21000 is compatible with OASE Control, providing options for electronic monitoring and adjustment when connected to suitable OASE control equipment.

For customers who want straightforward local control, the separately available Oase Eco Control can be used to adjust pump output and view information including power consumption, speed and operating time.

Submerged or Dry Installation

Unlike pumps restricted to underwater operation, the AquaMax Eco Expert 21000 can be installed submerged in the pond or dry installed.

This makes it particularly useful for more advanced filtration layouts and dedicated pump chambers where accessibility and pipework configuration are important considerations.

Protection for Year-Round Pond Use

Oase’s Environmental Function Control (EFC) provides protection against dry running and blockages, helping protect the pump if abnormal operating conditions occur.

The pump is also designed to withstand temperatures down to -20°C, making it suitable for permanent outdoor pond installations when installed and operated according to Oase’s instructions.
