Application
These are suitable for many applications such as Mine Drainage, Hydraulic Power Water Supply. Boiler Feed and other Pressure vessel charge duties, Pressure 'oil firing, High pressure spraying and Car Washing.
Design
The ME Series of Pumps are of Mono Block Multistage type, where the pump unit is directly mounted on the Motor Shaft. The intermediate stages (diffusers) are held between suction and discharge casings with tie bolts. The number of stages and length of shaft are arranged to suit the required head and pressure. Utilizing 60 years, experience in this field we have developed Impellers fabrication from Stainless steel. They have reduced water friction and are balanced, thus increasing the performance. The stuffing box is easily accessible for replacement of gland packing. Mechanical seal types are also available.
Specification
The Discharge body, pump cover, Diffuser, Pump support and Motor body are of Gray cast Iron, shaft of steel AISI 1050, Impeller of Brass and S.S. Enclosed type two pole motor with external ventilation single phase 220/250 volts 50 Hz capacitor type and three phase 400 volts 50 Hz is properly insulated.

CVN-LD are vertical-shaft centrifugal pumps built from PP or PVDF thermoplastic material (parts in contact with the process liquid). They are installed on a metal baseplate, coated on the tank side, and connected to the driving part by means of a flexible coupling. The supports consist of extremely reliable and hard-wearing separately-flushed friction bearings.
These pumps are typically used in all industrial sectors for the transfer of corrosive, toxic or hazardous liquids.

The vertical centrifugal pumps made in resin are high efficiency pumps for fixed installations with the pump immersed directly in a tank, operated by an electric motor in direct drive (max. 3000 rpm) for rapid emptying of fluid, with a flow rate of from 16 to 55 m3/hour. The particular form of construction of this pump, in addition to not using internal mechanical seals (subject to high wear), guarantees that any accidental leakage of the fluid is collected in the tank. The open rotor allows very dirty fluids, with an apparent viscosity of up to 500 cps (at 20°C) and small sized suspended solids, to be pumped with a continuous flow. The choice of the pump's composition materials allows you to determine the best chemical compatibility with the fluid and/or the environment without forgetting the correct temperature field.

The Metso Minerals VF froth pump has been designed to increase the pumpability of frothy suspensions. The principle of operation is similar to that of hydro- cyclone separation.
Air is separated from the slurry in a vortex created by the impeller rotation and the tangential inlet to the pump ’s conical sump.This results in more efficient pumping at higher capacities and a smooth operation, free from pulsations caused by airlocking.
Summary of design features
Integrated unit for layout flexibility
Smooth operation of the open vortex created in the sump and vertical "wet end" inlet prevents air locking
Cantilever design does not require submerged bearings or shaft seals
Bearing assembly with double protection sealing
arrangement to prevent ingress of slurry
Wear parts are available in a variety of different materials
Simplified maintenance

The centrifugal immersion pumps of building group 4 are used for wet-pit operation in containers, pits and tanks. Centrifugal immersion pumps for dry-well installation, i.e. to be installed and operated outside the container, are also available.
All components of pumps in plastic design that are in contact with the fluid are made of PP or PVDF. The pump shaft consists of a motor shaft made of stainless steel and a shaft-protecting tube of either PP or PVDF. Built-in elastomers are made of FPM (or also EPDM without surcharge). Centrifugal immersion pumps are equipped with overhang shafts so that there is no need to provide for shaft bearings in components that are in contact with the fluid. Thus, the pumps are safe to run dry and do not require regular service and maintenance.
There is no need of a mechanical sealing of the shaft. Only a so-called gas seal is installed beneath the motor to prevent aggressive vapours from penetrating the motor chamber. But this seal is never in contact with the fluid delivered.
- For aggressive and neutral liquids
- For short-term and continuous operation
