Choosing a Pump for your Pond

There are a number of things to consider when choosing a pump for your pond and the various different makes, styles and models is at first quite daunting.

This list is designed to help you know what to look for in a pond pump.

  • Flow rate, measured either in gallons per hour (GPH) or litres per hour (LPH), you need to pump the full volume of your pond through your filter approx. every 1˝hrs to 2hrs but check the requirements of your chosen filter system. For example a 2000-gallon pond needs a pump of around 1000 to 1300 gallons per hour. You should also allow some extra turnover for restrictions caused by pipe work and UV’s etc.
     
  • Waterfalls running off the same pump will require extra flow rate for example a 1 ft watercourse will require around 500 GPH.
     
  • Wattage is another important consideration, as your pump will need to run 24hrs a day 365 days a year. It is worth paying extra for a lower wattage pump as you will soon save yourself the additional cost via your electricity bill.
     
  • Warranties vary a lot any good pump will have at least three years cover.
     
  • A pump that can handle solids up to 10 mm is preferable.
     
  • Large inlet holes or slats clog a lot less and save you a lot of work.
     
  • Always tie some nylon string onto the pump as pulling it up to the surface by its cable will permanently ruin the pump.
     
  • Maximum Flow head is how high above surface level the pump can force water, if you need to pump water any height above the surface then check the chart normally found on the pumps box and allow extra GPH if needed.
     
  • If you have any doubt about a pump ask an experienced member of staff for advise as choosing an inappropriate pump is a very costly mistake. Make sure that it will fit the pipe work needed to connect it to your filter or UV.
     
  • Choose the right style of pump. Submersibles go in the pond and are the most commonly used for small box filters, although some can be used externally so long as they are below surface level. Vacuum pumps sit externally and suck the water from the filter back into the pond, these can pump vast quantities of water but are expensive to run.
     
  • Separate pumps are available for solely running fountains.
