Burtons BD 700 Pond Drum Filter

Burtons BD 700 Pond Drum Filter

High Capacity Self Cleaning Drum Filter for Large Koi Ponds

The Burtons BD 700 Pond Drum Filter is a powerful automatic mechanical filtration system designed for large koi ponds and heavily stocked ornamental ponds. These ponds require high water turnover and reliable debris removal. Burtons Aquatics manufactures the BD 700 in the UK using durable components and proven drum filtration technology. At the heart of the filter is a precision 60 micron stainless steel drum screen that removes fine waste before it can break down and affect water quality.

As the largest model in the Burtons BD drum filter range, the BD 700 offers exceptional flow capacity. At the same time, it maintains the same reliable self cleaning technology used throughout the range. As a result, it is an excellent choice for large koi ponds with high stocking levels and demanding filtration requirements.

Unlike traditional pond filters, the BD 700 does not require frequent manual cleaning. Instead, it uses a fully automated drum cleaning system. As debris builds up on the drum screen, the water level inside the drum chamber begins to rise. A float switch detects this change and automatically starts the cleaning cycle.

During the cleaning process, the drum rotates while a high pressure wash pump sprays the stainless steel screen clean. The system then flushes trapped debris into a waste tray and out to drain. Because this process happens automatically, the filter continues to operate without interruption. Consequently, water remains clear while maintenance requirements are greatly reduced.

How the Burtons BD700 Drum Filter Works

Pond water enters the drum filter through three large 110 mm inlets. It then flows through the rotating stainless steel drum screen. The 60 micron mesh captures fine debris including fish waste, uneaten food, blanketweed fragments and suspended solids.

As debris collects on the screen, the water level inside the drum chamber gradually increases. The internal float switch monitors this level and activates the cleaning cycle when necessary. During the cycle, the drum rotates while ten spray jets wash the screen using pressurised water. The system then flushes the debris through the waste outlet and discharges it to drain.

Because the drum cleans itself automatically, mechanical filtration remains efficient at all times. In addition, this process protects downstream biological filters by preventing solid waste from reaching the biological media.

The BD 700 works in both gravity fed and pump fed pond filtration systems. Therefore, it is suitable for a wide range of large pond installations. The BD range also has internal UV clarifiers which keep the water clear and the screen clear of bio film.

Why Choose a Drum Filter for a Koi Pond

Drum filters provide one of the most effective forms of mechanical filtration for koi ponds. First, they remove solid waste before it has time to break down in the water. As a result, water clarity improves and biological filters experience less strain.

Traditional sponge filters, pressure filters and bead filters often allow fine particles to pass through the system. In addition, they require frequent manual cleaning to maintain performance. By comparison, a drum filter removes debris automatically as it accumulates on the screen.

For large koi ponds with heavy feeding regimes and high fish stocking levels, drum filters provide a reliable and low maintenance filtration solution. Consequently, they help maintain stable water quality and healthier pond conditions.

Gravity Fed vs Pump Fed Installation

The Burtons BD700 can operate in both gravity fed and pump fed pond filtration systems.

In a gravity fed setup, water flows directly from the pond into the drum filter through bottom drains and skimmers. This allows the drum filter to remove debris before the water reaches the pump. Consequently, pumps and biological filters remain protected. In gravity fed installations the BD 700 can handle flow rates up to 75,000 litres per hour.

Alternatively, the BD-700 can operate in pump fed systems. In this configuration, a pump sends water from the pond directly into the drum filter. This approach is common on ponds that were not originally built with bottom drains. In pump fed installations the BD 700 can handle flow rates up to 55,000 litres per hour.

Please note that stock levels can change quickly on Burtons drum filters, particularly during busy periods. If your chosen model is not immediately available from stock, a member of our team will contact you as soon as possible with an estimated delivery timeframe.
