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).
“DryWet” system is supplied as standard on all the electric pumps of Energy range and enables customer to use a single model both for submerged applications and in dry chambers. The cooling system can be activated by simply adding oil to the pump. “DryWet” is an easy and efficient system that does not require additional maintenance, does not dissipate energy for the benefit of the electric pump performance and, in case of fault of the first mechanical seal, remains nevertheless fully operational.
