How the pump works

The self-priming system means that moving fish becomes a simple one man operation. Simply wheel the pump to your desired position, put the inlet hose into the tank or cage, prime and start pumping. All pumps feature fully variable drive systems, meaning fine control over pump speeds can be achieved. The powerful priming pump means that a 6” line can very quickly be primed from up to 3m below the pump. Restoring prime, if it is lost, is also very straight forward - just turn the prime pump back on. The pump can be used with any combination of 3”, 4” or 6” lines. Larger diameter output lines can also be used.

The impeller

The Heathro pumps are impeller pumps. The key to the high performance and gentle fish handling of this pump is in the impeller itself, which is cast, balanced and hand polished. The impeller is run at close tolerance to the heavy duty GRP shell, resulting in a pump that can easily handle fish between 0.2g and 400g. The pump can easily pump 5m heads and above and has a horizontal transfer of over 500m.

Three drive types

Three drive types are available - electric (three or single phase), petrol direct drive and hydraulic. Electric versions feature variable frequency drive (VFD) control over the main drive, which allows almost infinite control over the main pump speed. The electric version can also be fitted with a radio control up to 500m range.
