SS6 B SERIES

APPLICATIONS
Multistage mixed-flow borehole electric pumps, completely made in stainless steel (AISI 304L or AISI 316 on request), usable for wells from a minimum
diameter equal to pump size or greater and capable of developing a wide range of Flows and Heads.
These pumps can be used in a wide range of lifting, distributing, and pressuring application: domestic and general water supply; sprinkler and drip
irrigations systems; fire-fighting installations; lowering of groundwater level; industrial supplies as mining, hot springs, autoclaves and tanks.
These pumps are suitable both for standard water and for aggressive water applications by choosing the proper manufacturing material (AISI 304L or
AISI 316) both for hydraulic part and motor.
Special version of motors with PE2+PA windings can be used on request for high-temperature water applications up to maximum 50°C.
Pumps can be installed both vertically and horizontally simply by removing the non-return valve and adding a cooling sleeve to the suction case (the
only remark is to check the motor applicability to horizontal operations, refer to the motor specifications section).

CONSTRUCTION FEATURES OF PUMP
Mixed flow pumps with diffusers, impellers, brackets, suction case and discharge case completely made of stainless steel AISI 304 in order to provide
maximum strength, durability, wear and tear resistance.
The impellers are balanced and locked to the shaft with a specially shaped collet and nut coupling, in order to guarantee ease-to-assembly feature and
avoid vibration sensitive malfunctions and noise increase during rotation.
Rubber bearings that drive the shaft are water lubricated and have sand channels to make enable the sand particles leave the pump with the pumped
liquid (maximum permissible sand content 50 gr/m3).
Built-in non returned valve provided in order to minimize local friction losses.
Stainless steel strainer provided in order to prevent particles over a certain size from entering the pump.
Coupling with 6”, 8” or 10” motor depending on the power requested by hydraulic part:
– 6GF: 6” canned submersible motor
– TR6: 6” rewindable submersible motor
– TR8: 8” rewindable submersible motor
– TR10: 10” rewindable submersible motor
For inverter application refer to the detailed motor specification
