DEFENDER®, a smart device designed, tested and patented by Caprari to protect the electric pumps from electrochemical corrosion and galvanic currents, passivating the stainless steel so as to create a further safety barrier.

Sand Protector

Moreover, the special PROTECTOR ® device installed in Nema couplings between the wet-end and motor perfectly seals the coupling zone and protects it and the seal in the motor from sand.

HT Bearing

HT Bearing: strong resistance to the axial thrust extreme reliability

Smart-Fix System

Caprari Smart-Fix System Valve-pump casing fastening system


EASY-CHECK pump assembly system The assembly between the valve casing and the outer shell is achieved by means of an innovative threading system, namely EASY-CHECK, whose special profile and sand seal guarantee long-life and most importantly, prevent the valve casing from jamming. This makes it easier to disassemble and easier to inspect and maintain.

Sand-out System

Caprari Sand-Out System The new wear ring system ensures long life and reliable operation even when the pumped fluid contains large amounts of sand and solids. It also provides a reliable starting surge, thereby avoiding maintenance costs due to faulty operation

HT Coupling

New precision splined impellers, for high-power transmission and resistance to extreme stresses


An adapter kit that was especially designed to allow the coupling of Caprari motors with a proprietary attachment to hydraulic parts with different attachments (keyway and/or shaft key).

  • flexibility
