Hozelock pond pumps are the most reliable pond pumps in our large range. The pump is designed to run 24/7 with little or no maintenance and it manages to accomplish its mission with ease. Proof of its durable performance can be seen by the inclusion of a 3 year warranty on every pump sold. The Aquaforce 4000 is perfect for a typical family-sized garden pond up to 8,000 litres (2,000 gallons). The pump has the unique benefit of a Wildlife Protection System - this reduces the slots in the strainer cage to 2mm and can be employed when you have tadpoles in the pond or fish are spawning.
