Centrifugal Froth Pumps are designed to increase the pumping capacity of foam suspensions. The principle of operation is similar to the cyclone separation. In the vortex generated by the impeller rotation and the tangential inlet of the conical tank of the centrifugal froth pump , the air is separated from the slurry. This results in more efficient pumping and smoother operation at higher capacities.
Since the centrifugal froth pump, oil sump and motor are integrated on one unit, no leveling or special foundation is required.
The centrifugal froth pump does not require a stuffing box or other submerged shaft seals, no further simplification of maintenance and no sealing water.
The rugged bearing assembly is equipped with grease lubricated roller bearings. All bearings are rated for over 60,000 hours of operation and are above the slurry level.
Standard wear parts are soft natural rubber or nickel hard alloy. For special applications, wear parts of silicon carbide or synthetic rubber can be used. The centrifugal froth pump design allows the use of a combination of different wear component materials to optimize the service life of the worn components. The CVPF pump has a built-in pump housing lift mechanism for easy access to wear parts. However, the largest pumps require an external lifting device.
