This is the most powerful feature pump in the Blagdon range. It is the one we would recommend as it has enough \'oomph\' for larger features and can handle larger hose than the other models (up to 25mm). The pump also boasts an integral flow adjuster allowing you to turn the strength of the flow of water up or down as necessary. A unique feature of this range of pumps is they automatically switch themselves off if the water level falls too low - this prevents damage to the pump motor.
