MHWirth slurry pump for high
volumes
The new Wirth™ triplex double acting piston
diaphragm pump (TDPM) from MHWirth
combines two well-established and proven
pumping principles for the transport of high
volumes of abrasive slurry. The Wirth TDPM
works on the triplex double acting principle. It
has flow rates of up to 1,400 m³/h at a
discharge pressure of up to 8 MPa in the 3,000
kW input power version. This is a significant
increase in capacity compared to conventional
piston diaphragm pumps. “The powerful Wirth
TDPM offers a feasible alternative to many
multistage centrifugal pump systems”, explains
Frank Lengersdorf, Vice President Business
Development EMEA. “In addition to higher
efficiency and availability compared to
conventional solutions, it significantly reduces
spare parts consumption. Therefore it is a highly
economic solution.” The Wirth TDPM can be
used for traditional applications such as slurry
pipeline transport, autoclave feeding, mine
dewatering and ore hoisting. Additionally, the
pump is an efficient solution to pump thickened
oil sand tailings. For more than 40 years,
MHWirth has offered a full line of high-pressure
slurry pumps covering every type of slurry
application. These field-proven heavy duty
pumps have pressure ratings of up to 30 MPa
and flow rates of up to 1,400 m³/h. They are
operating successfully in numerous projects
worldwide.
Sustainable alternative to
nuclear density meters
Rhosonics has developed a non-nuclear density
meter for the mining industry and officially
introduced the new generation density meter at
the end of May this year. The Dutch company is
known as a specialist in the development
of ultrasonic analysis instruments which
are used in virtually any industry. The
company states: “When it comes to the
mining industry, in general companies do
not know about ultrasonic density
measurement. For a long time,
