The sewage pump M is a self-priming diaphragm pump. It works without a shredder. Even bigger solids can be conveyed without damaging the pump because of the lip valves which have been installed. The self-locking valves make the pump non-reactive, i.e. it can be mounted to the side standing, hanging or sideways. The intake and discharge bent is revolving. This is necessary for better connecting possibilities of the suction and pressure hoses. The suction and pressure connections usually go from left to right. They can easily be changed, if the suction way should go from right to left or from the bottom to the top. All parts which come into contact with water can be ordered in red brass or aluminium. The pump can be delivered with a 12 V or 24 V motor. Continuous operation 1 – 2 hours. Attention: The cross section of the pipe should never be less than 1 ½“/ 38 mm – or the pump capacity will not be achieved.
