ZF Vertical Mining Froth Slurry Pump

ZF froth pumps are double casing pump belongs to a type of vertical slurry pump. It could eliminate the froth in the slurry in running and work normally even if the feeding slurry is not enough. 

ZF pump is the ideal products to deliver the frothy slurry, especially in the flotation technique process.

Features

1. Easy installation & disassembly.

2. Integrated unit for layout flexibility.

3. Smooth operation of the open vortex created in the sump and vertical “wet end” inlet prevents air locking.

4. Cantilever design does not require submerged bearings or shaft seals.

5. Bearing assembly with double protection sealing arrangement to prevent ingress of slurry.

6. Wear parts are available in a variety of different materials.

7. Simplified maintenance.

Structure

The basic principle of the pump operation is to remove or partially remove the froth before the slurry enters the pumping. Its handling capacity is much higher than that of other types of slurry pump without shaft seal and sealing water. It is a perfect pump for handling frothy pulp.

The structure of pump head is double casing. All wet parts can be supplied in Ni-hard, high chrome alloy iron and pressure-molded natural or synthetic rubber. The driver end can be exchanged with ZL pumps. The hopper-tank is fabricated with steel plate. It's inner wall of the tank can be covered with liner according to different medium pumped.

The discharge branch can be positioned at intervals of 45 degrees by request and oriented to any eight positions to suit installations and applications.

Applications

ZF series of froth pump is widely used in metallurgy, coal, chemical, industrial sector. It is suitable for Suitable for handling solids-liquids mixture, special for delivering frothy pulp generated in flotation machines in metalliferous and coal flotation circuits.
