Pump supplier ITT Water & Wastewater has decided to offer its Flygt HS 5100 or HS 5150 submersible slurry pump at a discounted price after identifying a trend whereby vertical spindle pumps are being replaced with submersible pumps.
“The offer was initially until the end of July, but the demand has been so great that we have decided to extend the promotion to December,” says ITT Water & Wastewater marketing manager Lanelle Wheeler.
Wheeler says that slurry handling is considered one of the most demanding applications for any pump, and one of the most expensive in terms of wear and tear, maintenance and downtime.
“To increase efficiency and productivity, and to reduce costs, the mining industry is moving away from vertical spindle pumps and investing in submersible pumps instead. This pump is more user friendly, requires less infrastructure and operates at a low noise level. In some
instances, silent operation is guaranteed,” she explains.
No support structure is
required and the pump occupies less space than a vertical
spindle pump. Further, the motor and volute are an integrated unit, making it compact and easy to install, while the victaulic flange and coupling on the Flygt 5100/5150 series pumps allow fast, easy connection to a wide range of commonly
available fittings.
The Flygt submersible pump, which has been supplied to coal, gold, copper and platinum mines throughout Africa, is lightweight, easy to operate, requires less maintenance and, being engineered as a plug-and-play unit, it is easy to move without the need for larger handling equipment.
“Emphasis has been placed on the design and engineering of the pumps to produce a unit that
reduces maintenance requirements, extends pump life and facilitates a reliable pumping
installation,” says Wheeler.
All the pump’s wearing parts are manufactured from high chrome and the impeller is hardened for maximum wear resistance. The impeller has a more sweptback vane design compared with a conventional impeller, and ensures a homogenous flow, while the impeller hub is equipped with effective pump-out back vanes that expel abrasive particles.
An inspection chamber
between the seal unit and the bearings has a built-in sensor that allows for early detec-
tion of any fluid build-up,
reducing the risk of internal damage to the pump and
increasing its reliability in operation. Further, large throughlets
ensure more efficient pumping, even when larger particles are present.
ITT Water & Wastewater also offers an extended warranty
when clients buy monitoring and control panels with the submersible pumps.
“Monitoring and control are about giving customers a full solution. Pumps can be costly, so it is necessary to look after a pump installation. However, since not all installations are the same, it is necessary to take all aspects into account when
designing and engineering for monitoring and control,” Wheeler explains.
Over the years, Flygt has
developed a number of monitoring and control products, which are capable of increasing the
efficiency of the various pumps.
Wheeler says that ITT Water & Wastewater has seen a significant increase in the demand for monitoring and control panels, as these panels have become essential, rather than luxury elements of plant operation. It has become critical to
ensure the optimum functioning of a pump installation in light of increasing economic pressure within mining and other industries to contain operating costs.
Godwin Self-Priming Diesel Pumps
ITT Water & Wastewater has
expanded its rental fleet with the addition of five Godwin self-priming diesel pumps, which are the first in any South African rental fleet.
Upon arrival in South Africa, the five pumps were used in a long-term hire contract in Africa where power generation chal-
lenges make it difficult to dewater
with an unpredictable electricity supply.
“The Godwin self-priming diesel pumps are user friendly and are also capable of more demanding performance than most pumps, including dewatering applications where solids are present,” explains ITT Water & Wastewater rental manager Scott Gilchrist.
The pumps have extensive
application flexibility and can handle liquids with solids of up to 35 mm in diameter.
Gilchrist says that the Godwin brand was selected because of its globally proved operational
reliability, which is of particular importance in pit dewatering
applications. The pumps can handle a range of different media, such as raw sewage and slurries with solids, providing optimum flexibility in various environments.
The pumps deliver 70 ℓ/s at a maximum pump head of 130 m at their best-efficiency point. At shutoff, the pumps can handle a head of 150 m.
This enables units to be used at a far greater depth in the opencast pits, which is an important consideration for South African mining conditions. At full flow, the pumps manage 100 ℓ/s, obtaining heads of 80 m.
The Godwin pump can run for
up to seven hours at a rated capa-
city of 138 kW at 2 200 rev/min.
The fuel tank holds 300 ℓ, while the unit is 3 200 mm × 1 303 mm
with a height of 1 800 mm and has a dry weight of 3 200 kg.
It is a six-inch unit, with both suction and discharge capabilities.
Another advantage is that the pump’s maximum sound level is 81 dBA at 2 400 rev/min, with the Godwin HL Hush-Pac 150 m
being a completely soundproof unit.
The diesel pump offers contractors high-head and jetting capabilities, with solids handling. It is an all cast-iron construction, with a cast chromium steel impeller.
The continuously operated
Godwin venture air ejector priming device features a belt-driven air compressor, which requires no form of periodic
adjustment or control, adding to the simple maintenance charac-
teristics of the equipment.
Further, its dry-running, high-pressure oil bath mechanical seal has abrasion-resistant solid silicon carbide interfaces.
The solids handling swing-type nonreturn valve features a
renewable and flexible rubber seat, while its low-profile side discharge enables easy pipe connection.
“The unit, which is compact and mounted on a skid base with an integral, overnight running fuel tank, is powered by a Perkins engine. The pump is available for hire directly from ITT Water & Wastewater, as well as from our distributor network.
“It has proven to be so popular
to date that we will be considering adding further units to our fleet to meet demand,” says Gilchrist.
ITT Water & Wastewater will have a range of products including slurry pumps on display at
the biannual mining trade show, Electra Mining, in October.
