Choosing the right pond pump is crucial to the health and beauty of your pond. The choice depends on several factors:

  • Size your pond: Calculate the total volume of your pond. A general rule is that the pump should be able to circulate the entire pond volume every two hours.
  • Type of pond: Do you have a pond with many fish or plants, or an ornamental pond? This affects the required capacity of the pump.
  • Extra elements: Do you want a fountain, waterfall or other water ornament? These often require a higher capacity pump.

At A2KOI we offer a wide range of pond pumps suitable for different types and sizes of ponds. We are happy to advise you personally so that you can find the perfect pump for your pond. Please contact us or visit our store for professional advice.

The life of a pond pump can vary greatly, depending on various factors such as the type of pump, quality, maintenance and conditions of use. On average, a good quality pond pump will last between 5 and 10 years.

Some tips to extend the life of your pond pump:

  • Regular maintenance: Clean the pump and filters regularly to prevent clogging and overloading..
  • Correct installation: Make sure the pump is correctly installed and at the correct depth.
  • Protection from the elements: In winter, it may be necessary to protect the pump from freezing or temporarily remove it from the pond.
  • Prevent dry running: Make sure the pump never runs dry, which can cause damage.

At A2KOI, we offer a wide range of high-quality pond pumps designed for durability and reliability. In addition, we offer expert advice on installation, maintenance and protection to maximize the life of your pond pump.

The decision to turn off a pond pump depends on several factors such as climate, type of pond and the presence of fish. In areas with mild winters, the pump can often remain active year-round, especially if the pond is deep enough (at least 1 meter) to prevent complete freezing. This provides constant water circulation and oxygen supply, which is important for fish health and overall pond ecology.

In regions with harsh winters, it may be necessary to turn off the pump to prevent freezing damage. When turning off the pump, provide an alternative oxygen source to keep fish and plants healthy. When turning off the pump in the winter, it is important to clean and store it in a frost-free place.

At A2KOI, we are happy to advise you on the best policies for your pond pump during different seasons, based on your specific pond conditions and climate.

Basisprincipe van een Vijverpomp

De kernfunctie van een vijverpomp is het circuleren van water in de vijver. Dit is essentieel voor het onderhouden van een gezond vijverecosysteem. De circulatie helpt bij het verspreiden van zuurstof, het verwijderen van afvalstoffen en het bevorderen van een evenwichtige waterkwaliteit.

Componenten van de Vijverpomp

  • Motor en Rotor: De motor drijft een rotor aan in de pomp.
  • Waaier: Aan het einde van de rotor bevindt zich een waaier, essentieel voor het verplaatsen van water.
  • Inlaat en Uitlaat: Water wordt via een inlaat aangezogen en via de rotor en waaier verplaatst, waarna het door een uitlaat weer de vijver in gaat.


  1. Waterinlaat: Water komt de pomp binnen aan de voorkant.
  2. Aanzuigende werking: De draaiende rotor creëert een kracht die het water naar de waaier trekt.
  3. Waterverplaatsing: De waaier verplaatst het water omhoog door de pomp.
  4. Uitstroom: Het water wordt terug de vijver in gestuwd.

Deze werking wordt aangedreven door een elektrische motor, essentieel voor het continu draaien van de rotor en de watercirculatie.

Belang van de Pomp

De vijverpomp functioneert als het kloppende hart van de vijver en is cruciaal voor het levendig en gezond houden van de vijver. Het verwijdert schadelijke afvalstoffen en voegt essentiële stoffen zoals zuurstof en CO2 toe.

When choosing the right pond pump, it is important to know what types are available and what their specific functions are. Below is an overview of the most common types of pond pumps so that you can make an informed choice for your pond.

1. Controllable Pond Pumps

Features: These pumps offer the ability to adjust flow and power, making them very flexible for different pond conditions and seasons.

Application: Ideal for ponds where water circulation needs change, such as with changing weather conditions or fish populations.

2. Non Adjustable Pond Pumps

Features: These pumps have a fixed flow capacity and are simpler in design and use.

Application: Suitable for pond owners who need constant and reliable water circulation without the need for adjustments.

3. Fountain pumps

Features: Designed to supply water to fountains, often equipped with different nozzles for various water patterns.

Application: Perfect for adding a visually appealing water feature to the pond and for additional water aeration.

4. Submersible pumps

Characteristics: These pumps are fully submerged in the pond and are often quieter and less visible.

Application: Ideal for smaller ponds or as a discreet alternative, suitable for water circulation and filtration.

5. High Pressure Pumps for Drum Filters

Features: Specifically designed for use with drum filters, these pumps provide the higher pressure needed.

Use: Essential for koi ponds and other large ponds where powerful and efficient filtration is required.

Each type of pond pump has its own unique benefits and applications. When selecting a pump, it is important to consider the size of your pond, the presence of fish and plants, and specific aesthetic and functional requirements. Careful selection will ensure optimal health and beauty of your pond.
