High Pressure Centrifugal Pumps CVP

Product catalog summary

Overview: The document provides technical specifications and applications for OSNA high-pressure centrifugal pumps, specifically the CVP series. These pumps are designed for various industrial applications, offering high efficiency and low maintenance.

Shaft Sealing: The pumps use a mechanical seal for shaft sealing, ensuring reliability and durability.

Connections: The suction nozzle is R 1 1/2" and the discharge nozzle is R 1 1/4".

Lubrication: The pumps feature friction bearings lubricated by the pumping liquid itself.

Drive Specifications: The pumps are driven by IEC-standard 3-phase electric motors. For 50 Hz, the motor operates at 400 V, and for 60 Hz, it operates at 460 V. Both have insulation class F and protection IP 55.

Motor Options: Options include special voltage/frequency, higher efficiency class "EFF 1", PTC-resistors for frequency transformer operation, and integrated frequency transformers with PI-controller and sensor for motors up to 4 kW.

Design and Features: The CVP pumps are non-selfpriming, multistage, and vertically designed. They offer high efficiency, low noise, modular construction, and easy servicing. They come in three hydraulic sizes with one casing and have variable flange positions.

Applications: Suitable for pressure boosting systems, heating and water circulation, water supply, power stations, filter units, fire extinguishing, irrigation, and general industry.

Compatible Liquids: The pumps can handle fresh water, drinking water, boiler feed water, process water, sea and brackish water, hot water, condensate, lye, drilling emulsions, and other non-aggressive liquids.

Performance: Capacity up to 15 m3/h, head up to 200 m, speed up to 3500 rpm, and temperature up to 80°C (100°C). Casing pressure can reach up to 22 bar.

Materials: Impellers and shafts are made of stainless steel, diffusers and wear plates of Ryton, and casings of cast iron. Other materials can be selected based on the pumping medium.

Performance Range: The document includes performance charts for CVP 423, CVP 426, and CVP 428 models at different speeds (2900 rpm and 3500 rpm).

System Configurations: Systems can include one or two pumps with integrated frequency controllers. Modular construction allows for quick assembly of systems with up to four pumps.

OSNA-High pressure centrifugal pumps type CVP are optimal for operating compact pressure boosting systems Due to the variable flange position, the space required for each pump system is smaller than for systems with in-line pumps of similar size. The flanges will be positioned adequately according to individual requirements. CVP performance range at 2900 rpm Q(imp.gallon/min) 4 System with one pump, including motor type MAI with integrated frequency controller (up to 4 kW). Delivery includes the required sensor.
