Vertical turbine pumps, CR-CF

Suitable for medium capacity and high head

Centrifugal pumps are mainly manufactured for the pumping stations where the delivery of medium capacity of water with high head, even from a considerable depth, is requested.

The absence of priming and suction problems, which is the main feature of column vertical pumps in their standard construction, and the connection to standard electric motors, always accessible, allow a great simplicity in installation and running.

When the CR or CF pumps are lowered into a basin or a pit, they are ready to run.

Hydraulic characteristics

Capacity : up to 1.800 l/s (6.480 m3/h)

Head : up to 120 mt

Power : up to 2.800 kW

CONSTRUCTION

Since they are not mass-produced pumps, the construction can be suited to each specific application.

The standard construction of the MISA's CR-CF pumps series is designed for:

» installation with the pump casing submerged in the water of a tank or well;

» driven by electric motor, or, on request, to be driven by diesel engine through helical bevel gear‐box;

» column composed of flanged pipes and shafts connected by rigid couplings

» column length according to the installation as defined by the customer

» modular pump casing, the number of the stages depends on the required head

» shaft line in contact with the pumped liquid and supported by slide bearings made of special rubber or composite material lubricated by the same liquid

The special construction of the pump casings, associated with a ownership patterns, allows their execution in different metals and alloys, combined with the specific needs of the customer.

The quality of the product is however guaranteed by the specific production cycle through processing by CNC machine tools and, above all with intermediate checks in the stages of processing.

RELIABILITY

The reliability and proper functioning of MISA's CR-CF pumps is the direct consequence of:

» Sizing and construction solutions chosen in relation to the use of the pump

» Rotation speed below the first critical speed of the shaft line for trouble-free variable speed drives

» Checks during the processing and final testing

» Care in the processing and functional checks of each single pump

Fields of application

» Civil or industrial aqueducts

» Sprinkler irrigation plants in farming and fish farming

» Land reclamation

» Filling of artificial basins in electric power plants

» Civil and industrial plants for the water treatment

» Wastewater treatment plants, desalting plants, refrigeration of thermal power plants

» Steelworks with mill scale water

» Chemical and petrochemical industries

» Fire-fighting systems

Strengths

» Adaptable to specific applications and/or customer requests

» Absence of priming and suction problems

» Maximum simplicity of installation and operation

» Reliability and durability

» Careful choice of materials based on use

» Several impellers can be mounted in series to obtain greater head

» Operation is also possible with inverters

Peculiarities

The Misa CR-CF series pumps are special customized machines, suitable for the most varied applications, with excellent performance in wide ranges of capacity and pressures, also with the use of the pump-motor-inverter system.

Inverters are essential components in the pumping stations, especially in irrigation and aqueducts with pressure networks.

Wherever it is necessary to control fluids under pressure, an inverter, suitably configured, offers excellent performance, greater versatility and increased energy savings.

The structural verification and the correct sizing of the shaft line are decisive factors for the orientation on the regulated speed.

For this reason, we have always used proprietary dedicated software, suitable of analyzing every single aspect of the electric pumps to be built.

The structures of Misa pumps, both to always allow the use of the inverter and to avoid inconveniences on critical rotational speeds, are sized to work in safe conditions and below the first critical speed.

Checks during the construction and testing phases in our test room significantly reduce the inconveniences on the installation site.
