CONSTRUCTION FEATURES

PUMP

Abrasion resistant construction.
The front shim combined with the floating impellers guarantee an extremely abrasion-resistant configuration.
Upper and lower supports made of investment-cast stainless steel to ensure corrosion resistance, sturdiness and a rigid coupling with the engine.
The hexagonal pump shaft ensures effective driving of the impeller.
Stainless steel non-return valve integrated into the cylinder head.
The e-GS series pumps can be coupled indifferently to 4OS or L4C motors.

4” SUBMERSIBLE MOTORS - 4OS series - with rewindable stator in oil bath.
