Safeguard your fish stock: a permanent supply of oxygen and fresh water
Off-grid water circulation and steady water levels for fish farms, angling clubs and aquaculture. Protect your delicate ecosystem with no mains electricity at all.
The risk
The invisible danger: when your water turns in summer
In professional fish farming and pond management, oxygen levels and water quality decide between a good season and a complete loss. In hot, still summer months in particular, ponds warm up alarmingly fast. Oxygen levels fall away while toxic algae multiply at speed.
The painful result is a fish kill within a matter of hours. Yet most fish and rearing ponds sit well off the beaten track, out in open country or in woodland, where there is no mains supply for electric aerators or pumps. Generators are prone to failure, noisy, disruptive to wildlife, and their fuel bills eat straight into your margin.
For pond managers & club committees
"Is there really enough wind in summer?" Why this system saves your fish
As a pond manager or club official, you carry the responsibility for a valuable fish stock, so a little scepticism is only natural. Will a wind pump really work reliably enough in the height of summer to stop a pond from turning?
The biology of the water gives a clear answer: the wind works to exactly the right rhythm.
Nature's own safety mechanism
It is precisely on hot days that thermals and local air movement keep producing light breezes. Our green and yellow wind-powered water pumps start turning with very little effort: a wind speed of just 4 m/s is enough to set the mechanism in motion and start pumping.
Blackout-proof, whatever happens
When the grid goes down in summer through heat or overload, every electric aerator stops dead. Your purely mechanical wind pump simply carries on. Where there is no cable and no sensor, there is nothing to burn out or short circuit.
40 years of proven quality for your fishery
You are not buying an untested experiment. We have been building these rugged systems from hot-dip galvanised industrial steel for more than 40 years. Over 2,500 installations worldwide are proof of just how long they last.
A single service appointment a year is all it takes. You invest once and then protect your fish for decades at no running cost whatsoever.
The solution
Biologically clean, silent and utterly dependable
Our mechanical wind-powered water pumps use the free energy of nature to keep your water alive around the clock. That brings unbeatable advantages to your pond system.
Continuous water circulation
The pump draws up cool groundwater from deep below or actively circulates the pond water itself. That breaks up thermal layers and spreads life-giving oxygen evenly through every depth.
Oxygen enrichment through movement
Pumping fresh water in and letting it splash across the surface raises oxygen uptake dramatically, the best possible medicine against dangerous algal blooms.
A steady water level despite evaporation
The pump makes up for the heavy water loss caused by summer evaporation entirely on its own, topping the water up from your well. Rearing basins and reservoirs stay filled to the ideal level.
For every size of pond
The right solution for your water, tailored to you
Model W 3009 (the all-rounder for club waters)
The perfect choice for small to medium fish ponds, angling lakes or private rearing facilities at ordinary well depths.
Models W 4012 & W 5015 (the powerhouses for professional aquaculture)
Designed for large fisheries and deep boreholes. These models handle enormous flow rates, keeping even vast stretches of water permanently moving and supplied with fresh water.
Do not risk losing your entire fish stock
A single pond that turns can wipe out years of hard work and investment. Protect your water in good time, before the next extreme heatwave arrives. Testing the well, planning the foundation and installing the system all take a little lead time, so now is the moment to act.
