Froth Pumps

MINERALS

nnnn

Warman® froth pumps are heavy duty horizontal pumps designed to

nnnn

handle difficult tenacious froth

nnnn

Froth

nnnn

The problem of handling froth in some process circuits

nnnn

can be very frustrating. Froth often will air bind a

nnnn

pump. The Warman® froth inducer blade impeller is

nnnn

designed to solve this problem, through less surging

nnnn

and higher efficiencies from smaller pumps.

nnnn

Viscous slurries

nnnn

An additional benefit of this froth impeller design and

nnnn

oversized inlet is that it raises the solids concentration

nnnn

limits that a centrifugal pump can handle. As the main

nnnn

problem of handling froth is similar to that of handling

nnnn

viscous slurries - namely, getting the slurry into the

nnnn

pump so it can be pumped - this pump has proven to

nnnn

be a high performer in dense media viscous slurries.

nnnn

Additionally, flow surging problems common to other

nnnn

centrifugal pump designs at low flows are eliminated

nnnn

for viscous slurries.

nnnn

Application

nnnn

The mining industry is a primary example where

nnnn

pumping operations can be plagued by froth and high

nnnn

viscosity problems. In the liberation of minerals from

nnnn

ore, the minerals are often floated through the use

nnnn

of strong flotation agents. Tough bubbles carry the

nnnn

copper, molybdenum or iron tails to be recovered and

nnnn

further processed. These tough bubbles create havoc

nnnn

with many slurry pumps, often leading to the selection

nnnn

of overly large and inefficient pumps. Warman® froth

nnnn

pumps are small and efficient. The inducer impeller

nnnn

and oversized inlet very effectively enable the froth or

nnnn

viscous slurries to get into the impeller allowing the

nnnn

pump to transport it to the next destination.

nnnn

Low power costs, reliable operation, minimal

nnnn

surging, and feed tank overflow make

nnnn

Warman® froth pumps user friendly.
