Addition to high-head dewatering applications

Weir Minerals has launched the

latest edition in its range of

Warman centrifugal pumps, the

DWU dewatering pump, to the

European market.

The pump is designed to deliver

increased effi ciency where water

needs to be lifted over greater

heights – a common requirement in

both open and underground mines

– and the unit delivers effi cient

operation at heads of up to 140 m.

Four diff erent sizes are available,

with outlet diameters of 75 mm,

125 mm, 150 mm and 200 mm

and around 50% of the parts used

in the new design are inter-

changeable with Weir Minerals’

popular slurry pump, the Warman

WBH, to help clients simplify spare

parts ordering and holding.

Weir Minerals’ engineers have

designed a new, double-volute

casing which reduces radial load

and is capable of maintaining

internal pressures of up to 7,000

kPa, allowing the pumps to be

confi gured in series to deliver

even greater head heights.

Steve Sedgwick, the Weir Minerals

Europe product manager for

mine dewatering, said: “The

dewatering system is a crucial

part of almost every mining

operation around the globe, and

we’re committed to ensuring that

our range of dewatering pumps

is broad enough to deliver

optimum effi ciency, whatever

the requirements.

people and treats around

900,000m³ of water per day.

The Verderfl ex Dura 35 peristaltic

hose pumps were chosen because

of the compact nature, especially

compared with alternatives such as

screw pumps. The Dura 35 has the

added benefi t that the corrosive

PAC fl uid being pumped does not

come into contact with any moving

parts and is contained within the

heavy-duty hose.

The plant manager stated that

,“Gone are the days where we have

to go down to the hardware store

and buy a coupling or a bearing to

repair the pump, there is only the

hose and that’s it, we can change

the hose in situ”.
