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.
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: strong resistance to the axial thrust extreme reliability
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.
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
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).
