PROPELLER PUMPS- PP
Propeller pumps are of an axial type i.e. where water flows into a suction bell axially passing via impeller and stator diffuser, being further directed through a discharge pipe of piping. The shaft is by means of a flexible coupling joined with an electric motor. Propeller pumps are applied for the supply of high quantities of water at low heads, being thus very economically applied in the systems of irrigation and drainage, industry and others. Upon a customer’s requirement, the pumps provided with deflecting blades in operation, are also produced.
Shaft sealing:
The shaft sealing could be arranged by soft packing arrangement, the shaft is protected by replaceable, stainless steel sleeves.
Drive:
- Electric motor;
- Diesel engine with a right angle gear unit upon request.
Arrangements:
Propeller type of pumps could be arranged in several modifications, depending on:
- Customer requirements;
- Working and medium conditions;
- Space available;
- Applications where a special design is needed.
Applications:
For supply of big quantities of water at low heads. Typical applications are in:
- For Drainage;
- Industrial plants;
- Irrigation systems;
- General purposes.
