C2PO
C2PO heavy duty process pumps are horizontal, between bearings with a axially split casing, double suction, one stage impeller. The specific pump construction allows to achieve very high efficiency with low NPSHr values. Robust casing, stiff shaft design and different bearing arrangements to meet specific applications make the C2PO a fully reliable pump granting long life in service and reduced maintenance costs.

CKVN
CKVN - CKVN-B are vertically-suspended, single or multi-stage centrifugal pumps (VS1 or VS6 configuration), designed and built in full accordance with API 610 norms. Bowls are integrally cast diffuser type to assure optimum hydraulic efficiency and minimum radial thrust. A generously sized, carefully designed line shaft assures rotor stability and low vibration level.Rotor axial positioning and support is granted through an oil lubricated double row ball thrust bearing.

HC
Radially split centrifugal pumps with close impeller complying with ISO 2858/DIN 24256/ISO 5199 Norms. A sturdy and deep stuffing box allows to fit single or double, either conventional or cartridge design mechanical seals. Upon request, they can be equipped with heating/cooling chambers on the pump casing and/or stuffing box. HC Pumps can be manufactured in any material combination depending on actual conditions of service.

HCMD
Single volute hermetically sealed pump thanks to the replacement of the traditional mechanical seals with magnetic device.This solution allows a substantial reduction of maintenance interventions and, consequently, of the running costs. All the parts included between the motor and the pump casing can be removed without disconnecting the discharge and the suction piping and with no interventions on the motor.

HCV - VXV
Vertical single stage centrifugal pumps derived from ISO 2858/ DIN 24256 Norms. The casing is always immerged in the liquid while a discharge pipe brings the discharge branch to the outside of the plate covering the pit. The standard shaft length varies from 1 to 6 meters. HCV pumps are generally in stainless steel, but can be supplied in other materials or alloys according to the liquid to be pumped.

VX
Radially split single stage pumps with vortex impeller which allows for certain sizes to handle liquids with suspended solids having a size up to 80% of the nozzle diameters. The packing gland allows the installation of mechanical seals and packing rings of any kind. Upon request, they can be fitted with chambers to cool or heat the casing and/or the stuffing box. They are normally manufactured by using a wide variety of metallurgies, such as cast iron, nodular cast iron, carbon steel, stainless steel and special alloys. Specifically designed to handle liquids with suspended solids and sludge (raw and decomposed up to 6%), especially in treatment plants systems, paper mills (dry residual up to 8%) and for application in the sugar, chemical and steel industries.

ISO 5199 / ISO 2858 Technical specifications for centrifugal pumps — Class II
This International Standard is one of a set dealing with technical specifications of centrifugal pumps; they are designated as Classes I, II and III. Class I comprises the most severe and Class III the least severe requirements. The selection of the class to be used is in accordance with the technical requirements for the application for which the pump is intended. The class chosen should be agreed between the purchaser and supplier. Furthermore, additional safety requirements concerning the field of application should be taken into account. However, it is not possible to standardize the class of technical requirements for centrifugal pumps for a certain field of application, because each field of application comprises different requirements. All classes (I, II and III) can be used in accordance to the different requirements of the pump application. So it may happen that pumps built in accordance with Classes I, II and III may work beside one another in the one plant. Further requirements covering specific applications or industries may be dealt with in separate standards. Criteria for the selection of the required class of a pump for a certain application may include: — reliability,
— required operating life,
— operating conditions,
— environmental conditions,
— local ambient conditions.
