Well pump dab SS7
Well pump dab SS7Multistage submersible well pumps, the main parts and assemblies of which are made of stainless steel (AISI 304L or AISI 316L on request). The pumps are designed for wells with a diameter of 6 inches or more and have a wide range of flow and pressure characteristics. Designed for domestic and industrial water supply systems, for supplying water to autoclaves and tanks, for installation in fire-fighting systems and high-pressure flushing systems, for agricultural irrigation systems. Depending on the selected material of the hydraulic part (AISI 304L or AISI 316L), it is possible to pump clean water or other aggressive liquids.
TECHNICAL CHARACTERISTICS
- Operating range: flow up to 110 m3/h, pressure up to 423 m.
- Max. concentration of sand/silt in the liquid: 50 g/m3.
- Maximum liquid temperature: 30 °C (50 °C on request).
- Discharge pipe diameter (internal thread): 5’’
- Special execution on request:
-Hydraulic housing made of stainless steel. steel AISI 316 for pumping aggressive liquids;
-Impellers made of stainless steel. steel AISI 316;
-Electric motors made entirely of stainless steel. AISI 316 steel for pumping aggressive liquids;
-Design with star-delta starting;
-Electric motors of special design for working with liquids with high temperatures;
-Non-standard coupling.
DESIGN FEATURES
For working with high-temperature liquid (not more than 50 °C) or with an inverter, it is possible to order a special electric motor versions with stator winding wires having insulation made of cross-linked polyethylene and polyamide (PE2+PA). These pumps can be mounted in a vertical or horizontal position. For horizontal installation, simply remove the check valve and install a cooling casing on the suction chamber and the electric motor (for the possibility of operating the motor in a horizontal position, see the technical specifications of the electric motor). To ensure maximum service life, these pumps are equipped with diffusers, impellers, brackets, suction and pressure chambers made entirely of stainless steel. AISI 304 steel.
Depending on the power consumption of the hydraulic part, the pump can be equipped with motors of the following standard sizes:
- 4GG: submersible well electric motor with a non-removable stator 4’’
- 6GF: submersible well electric motor with permanent stator 6’’;
- TR6: submersible well electric motor 6’’ with rewindable stator;
- TR8: submersible well electric motor 8’’ with rewindable stator;
- TR10: submersible well electric motor 10’’ with rewindable stator.
