Optimum Colliery has replaced ageing
cooling oil pumps with ten new Viking
model H4124A internal gear pump sets
fitted by supplier Mather+Platt with
2,2 kW motor-gearbox combinations and
mounted on mild steel base plates.
The order is a consequence of a
proposed solution to inefficiencies expe-
rienced with the older, belt-driven pumps
installed on crushers at the colliery, where
vibration was causing belts to slip on
their pulleys and occasionally become
dislodged.
Mather+Platt proposed that the new
Viking pumps be connected directly to
their motors and gearboxes to overcome
this problem, and mounted on base plates.
Optimum’s new machines are heavy
Optimum replaces ageing pumps with Viking units
duty standard gear pumps with duties of
0,16 litres/s at a head of 13,8 bar.
They come from Viking’s universal seal
pump family, which is manufactured in
twelve sizes and features castings from

Colliery.
stainless steel, ductile iron or cast iron.
Customers can choose between gland
packing, component seals or cartridge
seals, and there is a behind-the-seal option.
Flanged or NPT ports are incorporated in
multiple locations. Jacketing is optional
and a pressure relief valve is standard.
Mather+Platt reports steady sales of
Viking internal gear pumps. TheWadeville-
based company last year increased stock
holdings across the Viking range to reduce
delivery times, and claims to hold the
largest ready stock of these pumps in
South Africa.
Series 4125 pumps in the range can
handle liquids with viscosities up to
15 000 SSU.

Latest Smartcom leaky feeder system has modular design
Becker has introduced its latest SmartcomVHF leaky feeder system,
which ensures dependable underground communications.
“The SmartcomVHF leaky feeder systemoffers theminesmultiple
simultaneous voice and data radio channels, with low intermodu-
lation noise levels, to ensure clear and reliable communications
underground, at all times,”says Johann Smit of Becker Mining South
Africa.“This leaky feeder system, with a modular design, features the
option of local and remote diagnostic amplifiers with manual and
automatic gain control to ensure every installation and subsequent
maintenance procedures are safe and effortless.
“Mines are usually remote to major cities and established infra-
structure, which makes access to communication specialists and
services difficult for the mining sector. The Smartcom VHF leaky
feeder system, which has been installed in mines throughout
the world, is known for dependable performance, requiring little
maintenance.”
The system is designed with local diagnostics via three on board
LED indicators as standard. This unit facilitates fault finding and sys-
tem troubleshooting by quickly being able to identify the faulty
component and communicate relevant information on the display
unit, thus reducing downtime and repair costs. This amplifier is
suitable for installations that do not require the added expense of
Ethernet and where remote diagnostics are not necessary.
Becker’s latest Smartcom VHF leaky feeder system, with local
and remote diagnostics, also has Ethernet capabilities. The unit has
the functionality to send information to an amplifier installed on
the surface, enabling a control room operator to retrieve relevant
information. This is particularly useful in the event of a system fault,
as the operator can easily identify precisely where the problem is.
The system also provides relevant information on what equipment
is needed to repair the fault.
The flexibility of this system supports both analogue and
digital radio repeaters, which means users have a choice of radio
infrastructure.
Smartcom also supports telemetry and can be used for effec-
tively controlling underground equipment such as ventilation
fans, pumps and stench gas fires. Important information is com-
municated efficiently back to mine control systems for optimum
productivity and enhanced safety.
