 Solidity and reliability
The vertical centrifugal with coupling range CGV-N, has been designed in order to obtain the best performances and a total reliability. Easy to handle, the pumps of this range are strong, compact construction, produced in their components with high thickness to give a product with the maximum strength. Suitable to transfer acid and basic solutions, the wet ends, are produced in thermoplastics (PP-PVDF-PEHD)and O-ring in the proper elastomer material (EPDM-FPM-FEP). Pump shaft connected to the motor through the elastic coupling with inside ball bearings, is guided trough PTFE CG and Al2O3( alumina) bushings; available upon request is the alternative combination in SiC-SiC ( silicium carbide). The impellers installed are generally semiopen, but they are available in the closed version for hot liquids and without solids in suspension. Standard columns length are 500-750-1000-1250-1500-1750-2000-2250-2500-3000 mm.
Exercise temperatures and materials
MATERIALS SELECTION
The materials used in the production of our pumps, are carefully selected based upon the pumped liquids. Each material used must answer at mechanical and chemical characteristics in order to grant the best reliability of the pump. The working temperature is a really important condition, especially because the thermoplastics are materials very sensible to low and high temperatures.
Performances
PUMPS SELECTION
Pumps are selected based on the data project transmitted from the Customer. Capacity Q, head H, specific gravity and liquid viscosity, temperature, are required in order to proceed to the correct pump choice. For the best selection, the chosen pump has to work close to the best efficiency point of the curve in order to obtain a reduced energy consumption and to avoid abnormal hydrodynamic situations (cavitations, turbulences, etc.).
