Laguna pumps are highly efficient and long-lasting. They are designed to circulate water with up to 6 mm of solid particles and move them to the filter system, effectively filtering the waterfall, resulting in less maintenance. They feature a click-fit feature, allowing a quick disconnect of parts for easy cleaning. What size pump do I need? After choosing your pond pump's purpose, you will need to calculate the flow rate in litres per hour. Pump flow rates drop when you pump higher and further than the pond, so you need to consider these effects. You should aim to purchase a pump that meets the maximum flow rate of your filter at its height above pond level. To comply with UK electrical legislation, pond appliances can't be supplied with a fitted plug, so you'll need to purchase one separately or wire it into an outdoor plug socket.
