Flood Prevention Pump

Construction: the bap 500-iii type aggregate consists of a pump with spiral casing having An opened mixed flow impeller, and a diesel engine which are connected by a flexible Coupling. In the discharge nozzle of the pump casing there is a flap valve which is adjustable By means of handwheel. Priming of the pump casing at starting is by means of an exhaustoperated Gasjet air pump. The cover age of the engine is made of welded steel sheet Construction with two lockable doors. The pump and the engine are mounted on a wide Sledge runners. This solution ensures safe operation of the unit even on wet ground. The Engine is equipped with a mechanical starter so at operating there is no need for storage Battery. The equipment has a protection against overheating, shortage of lubrication and Fuel and v-belt rupture. In these cases the protection stops the aggregate. Medium handled: clean water at temperature not exceeding 40 to 45 °c, neutral in Reaction and silty water containing no large solids. Max. Silt content: 1000 mg/dm3. Field of application: these pumps are used primarily for land drainage, lifting and irrigation. However, they can be used advantageously in places where, in default of installed energy Sources, quick installation and putting into operation is required. Bearing support: the gear drive and the pump are carried in oil lubricated roller bearings. Main structural materials: impeller, flap valve and flap valve casing: cast iron. Suction pipe, spiral casing, gear: aluminium casting.
