Exclusive systems and patents

DRYWET: OIL COOLING SYSTEM

INTERNATIONAL PATENT

DryWet enables the user to employ just one single pump model both in submersed applications and in dry chambers. No additional maintenance is required in this simple and efficient system. Moreover, performance is boosted thanks to a lack of energy dispersal. This all comes as standard in the K+Energy range.

K+ NONSTOP: ANTI-CLOGGING SYSTEM

EXCLUSIVE PATENT

The only wastewater pump with 4 combined anti-clogging measures:

  1. The widest free passages on the market
  2. Fibre cutting system in the back-impeller zone
  3. Blading on the disc to the hub
  4. Blading on the lower part of the impeller

HT BEARING

INTERNATIONAL PATENT

HT Bearing: maximum resistance to axial thrust and extreme reliability. Guarantees an ample safety margin against axial load generated by the hydraulics.

SAND OUT SYSTEM

INTERNATIONAL PATENT

Caprari’s Sand-Out System is a shim system which ensures durability and reliabile performance even in the presence of significant levels of sand and solids. In addition, this system guarantees that the motor starts, helping to avoid maintenance costs related to malfunctions.

EASY FIT

EXCLUSIVE PATENT

Innovative device which allows for the extraction of the stuffing box at the assembled pump, accessing at the packing site and performing the replacement directly on the system.

HT COUPLING

EXCLUSIVE PATENT

New shrink-fitting precision-grooved profile impellers, for powerful transmission and resistance to extreme stressors.

MOTOR PROTECTOR

EXCLUSIVE PATENT

Device to protect the pump-motor coupling: the area is sealed, protecting the joint and the motor’s mechanical seal from sand.

CONDUCTIVITY PROBE

INTERNATIONAL PATENT

The probe immersed in the oil box, also in the ATEX version (Caprari International Patent), prevents any water from infiltrating the electrical part, ensuring timely maintenance and guaranteeing that the motor is protected.

SMART-FIX SYSTEM

INTERNATIONAL PATENT

Caprari’s Smart-Fix System: a fastening system for the valve-pump casing which is resistant to high pressures over 70 bar.

CPLUS

EXCLUSIVE PATENT

The best pumping solution in applications with electric submersible pumps operated by VSD – Variable Speed Drive. The same configuration of the submersible group can be employed in conditions of extreme temperatures. The new motor, with its double-insulated winding aimed for use in high-temperature water, is enhanced with technical upgrades to make it even more robust and suitable when operated by electronic devices with variable frequency.
