CONSTRUCTION CHARACTERISTICS

PUMP
Abrasion-resistant construction. The front wear plate, combined with the floating impellers, ensures optimum resistance to abrasion.
The upper and lower supports are made of precision-cast stainless steel, ensuring resistance to corrosion, durability and a sturdy coupling to the motor.
The hexagonal pump shaft guarantees an effective impeller driving.
A stainless steel non-return valve is fitted in the discharge to prevent any back flow of water and alleviate any water hammer to the pump, thus safeguarding impellers and diffusers.
The GS series pumps can be coupled to either the 4OS or L4C motors.

OPTIONAL FEATURES
Different voltages and frequencies.
