TRAITEMENT DES EAUX  →  POMPES CENTRIFUGES EVA

The CPK centrifugal pumps are constructed following the process and in accordance with DIN 24.256 for chemical industry.
All pump sizes of this type are graduated in relation to each other. This fact can give the best efficency and the right NPSH value for each case.

The CPK series are used for chemical food, pharmaceutical and textil industries, as well as for heating plants and high temperatures plants, and for many other general uses.
CPK pumps are supplied for the following futy conditions: Q up to 1.300 m³/h, total heads up to 150 m.c.l. at temperatures of 300°C, and final pressures of 25 kg / cm².

Normalized pump in accordance with DIN 24.256, and for vertical construction.

CASING
Volute casing in spiral open towards the discharge side, foot support at the botton with end suction nozzle, and with double spiral from the 315 size.

IMPELLER
Closed radial impeller, with hydraulic compensation by edge blades.

SHAFT AND BEARINGS
Five sizes of bearing support cover the whole pump range, bearings lubricated by oil. All bearings supports are supplied with and oil level controller.
In the heavy duty bearing execution, cylindrical roller bearing goes in pump size and the angular contact ball bearing goes in motor side.

SHAFT SEAL
Packing stuffing box connection for seal liquid, or cleaning liquid, with cooled/heating stuffing box in all pumps.
Mechanical seals of various manufacturers can be fitted.

EXECUTIONS

• Execution "R" Reinforced bearing support
• Execution "f" Special flanges
• Execution "m" Mechanical seal
• Execution "H" Heated (in case of pumping hot liquids

The pump is supplied in five standard material executions:

• G (Cast iron)
• B (Bronze)
• S (Ductile iron)
• C (Stainless steel)
• E (Cast Steel)

The CPKN centrifugal pumps are constructed following the process and in accordance with ISO 5.199 for chemical industry.
All pump sizes of this type are graduated in relation to each other. This fact can give the best efficency and the right NPSH value for each case

The CPKN series are used for chemical industry, paper industry, sugar industry, as well as high temperatures plants, and for many other general uses.
CPKN pumps are supplied for the following futy conditions: Q up to 300 m³/h, total heads up to 150 m.c.l. at temperatures of 300°C, and final pressures of 25 kg / cm².

Normalized pump in accordance with DIN 24.256

CASING
Volute casing in spiral open towards the discharge side, foot support at the botton with end suction nozzle, axial entry and radial discharge nozzle.

IMPELLER
Closed radial impeller, with hydraulic compensation by edge blades.

SHAFT AND BEARINGS
Three sizes of bearing support cover the whole pump range. Cylindrical roller bearing goes in pump size and the angular contact ball bearing goes in motor side. All bearing supports are supplied with and oil level controller.

SHAFT SEAL
Pumps are sealed by simple and balanced mechanical seal, in accordance with several API. Mechanical seals of various manufacturers can be fitted.
Shaft can also be sealed by gland packing.
