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.
