50ZJF Rubber Lined Tank Slurry Scum Pump for Pulp and Paper Industry
1. What is a froth pump?
The ZJF froth pumps has been designed to increase the pump ability of frothy slurry. The pump operation is similar to hydrocyclone seperation.
The basic principle of the froth pump operation is to de-aerate or partially de-aerate the froth before it enters the pumping. Its handling capacity of the pump is muchhigher than that of other types of slurry pump without shaft seal and sealing water.
2. What advantage of ZJF slurry pump?
The advantages of the pump are of excellent performance, easy assebly & disassembly, high reliability and etc.
High efficiency | Handing solids-liquid mixture, special for delivering frothy pulp generated in flotation machines in metalliferous and coal flotation circuits. |
Wide usage | Handling all applications involving of air entrained slurries, such as flotation froth in base metal concentrators, phosphate and apatite washing plants and calcium carbonate upgrading plants. |
As a mixing and distribution unit, where dry powder has to be mixed (and wetted) with water. It can also be used with cement in ready mixed concrete sand for grouting and injection mixing. |
