From Typology - Flanged Surface Pumps with Heat Engines
Single-impeller pumps with SAE low head flanged support. Surface pumps for power take-off. Possibility of making motor pumps.
Description
PRESENTATION FD SERIES
These horizontal axis centrifugal pumps are equipped with a support with connection flange for direct coupling to heat engines. A sturdy flanged support in accordance with “SAE”, the shaft with three bearings in oil bath and an elastic coupling, allow the FMS series to be flanged directly to the flywheels of diesel engines. Therefore the type of motor and the specific SAE size of the coupling bell are sufficient to determine the dimensions of the flange and consequently of the elastic coupling.
The FD series, designed for setting up small motor pump groups, is equipped with a support without bearings with special flanges. The pump shaft can be coupled to the flywheels directly or by means of a rigid coupling.
The ease and safety of these couplings guarantee perfect and constant alignment, satisfying the needs of an ever better functionality in setting up the motor pump groups.
CONSTRUCTION FEATURES:
The carefully processed and selected materials used are: fine-grained gray cast iron for the hydraulic part and the support, tempered steel for the pump shaft. In multi-stage pumps, the intermediate diffusers with guiding blades and the volute delivery body are fitted with easily replaceable sealing rings at each impeller. The centrifugal impellers are dynamically balanced. In correspondence with the gland packing, the pump shaft is protected by an easily replaceable hard chrome-coated brass bushing. In multi-stage pumps, the shaft is always guided by a support with bushing located in the suction cover.
LIMITS OF USE:
According to the materials normally used in production, the FMS / FD pumps are suitable for lifting fresh water, which is chemically and mechanically non-aggressive.
- Maximum water temperature: 90 ° C.
