Sulzer Mine Dewatering Pump
HPH/HPL These multistage pumps are specifically
designed for mine dewatering applications. Their
robust construction is designed to combat the
highly abrasive environment in which they
operate. Extensive use of replaceable wear
surfaces ensures the pumps can be rapidly
refurbished to as-new condition without extensive
replacement of core parts.

NorthParkes Dewatering Pumps
The high pressure and solids handling capability
enable these ZPM 800 pumps at Northparkes
copper-gold mine, Australia, to
transport unsettled mine water from a raised bore
sump to the storage dam, at the surface, in a
single lift. After the pioneering work at the
Elura mine in Australia in 1982 dirty-water
systems were refined and have become the
preferred method to dewater underground mines.

Autoclave Feed Pumps
The Goldstrike and Twin Creeks gold ore pressure
oxidation plants use autoclave feed pumps The
horizontal dropleg orientation results from the
higher temperature, pressure and capacity
requirements of the Murrin Murrin, Bulong and Rio
Tuba nickel laterites refineries.

Hydraulic driven piston pump
Positive tube thrust puts an end to manual tube
end float adjustment and premature
tube replacement due to washout of the tube and
wear of the splined shaft.
The model DHTs pump water end comprises a hopper
with transfer tube. This S-form pipe pivots on
the discharge side whilst the inlet is
intermediate between the opening of the paired
cylinders. At the end of a suction stroke it
covers the cylinder opening and isolates the
filled cylinder from the suction hopper. During
the subsequent discharge stroke, the piston
forces the product through the tube into the
discharge pipe. During switch over the tube
partly overlaps and short-circuits the
cylinders for a fraction of a second
15
Paste Application of Piston Pumps
When pumping a paste consistency, the backflow
from discharge to hopper will be minimal and the
resulting pressure pulsations, while not
insignificant, will be quite acceptable in an
adequately anchored piping system. The tube
inlet opening is fitted with a nozzle, which
slides over a wear plate. Where the tailings are
particularly abrasive, ceramics improve wear and
galling resistance.
The El Indio gold mine backfill pump transports a
76 Cw cement based paste fill to the voids left
by the mining operations. The paste mixer
discharges into the hopper, which is open and
tapered to suit the feed requirements. South
Deep mine in South Africa transports backfill
over 1250 metres from the underground crushing
plant to the elevated stopes where the 85Cw
mixture of crushed waste and 15 mm aggregate
helps to prevent rock bursts.

Mono Operating Principle
18
Mono mining packages have been employed in the
Australian mining market for over 30 years.
Available as stand alone units, travellers or
main multiple permanent pump stations, with
or without hoppers, discharge pipe-work and
valves. Mono can provide a package in 1,000 or
415 Volt to meet all your dewatering needs.
