Features And Construction

Cable entry with core wire seal
The core wire seal prevents water from penetrating into the motor through the core wire.
Motor protector
A thermal protector (built-in automatic reset type motor protector) or thermal switches are embedded in the motor winding
Shaft seal
A highly wear resistant double mechanical seal combined with the use of an oil seal further extends working life. (not available on all models)
Air-filled submersible motor
Discharge connection
The pump is automatically connected to the discharge pipe.
Impeller
Single-vane, semi-open channel impeller with helix formed passage realizes excellent pass-through capability. All impellers are subject to the dynamic and static balance adjustment at factory.
