E4XP Series - Electric Stainless Radial Submersible Pumps

In a class of their own, E4XP pumps have a precision cast stainless steel structure to guarantee lasting performance even in the most critical applications, such as particularly aggressive and/or abrasive waters. To guarantee long life even in particularly sandy areas, in addition to high-resistance materials, E4XP pumps also feature other ground-breaking, exclusive solutions never used on this type of product before.

"DEFENDER" Galvanic Protection

All E4XP pumps are fitted with a "DEFENDER" galvanic protector in the pump/motor coupling area. This device acts as a sacrificial anode to effectively protect the pump and electric motor from corrosion and galvanic currents at all times. An international patent has been filed for this pioneering invention.
