Atlas Copco offers efficient dewatering pump solutions

The Latchways PRD range includes a Workman Premier and Workman Utility full-body harness. A rescue pole is also avail- able, which can be used by a third party to activate the Latchways PRD in the event of a worker at height being incapacitated. The rescue pole is 800 mm when retracted and 3 400 mm when extended. MSA Africa’s harness-systemoffering has been enhanced further with the addition of its Latchways 3mPersonal Fall Limiter (PFL), pictured left, which is designed specifically for environments where close anchorage is available. The lanyard uses multiple- spring radial energy-absorbing technology, believed to be a world-first. The new design eliminates the need for an external energy absorber outside of the housing, resulting – says MSA – in this being the most compact PFL available on the market today. MSA, website: za.msasafety.com are specially designed and engineered to deliver reliable operation in stringent conditions where start-up can often be a challenge. The PAS range features a high-capacity diaphragm pump for automatic prim- ing. In the PAS pump system, the air is separated from the liquid in the large SuperDuo separator and is sucked by the vacuum pump, making automatic priming possible. Thanks to the pump’s dry prime capabilities, the end-user can start pump- ing immediately with a simple flip of the switch. The VAR, for its part, has an immedi- ate water fill-in mechanismwhich makes it ready to prime and start pumping. The inclusion of a centrifugal pump with a semi-open impeller enables both systems to pump liquids with solids of up to 76 mm in suspension without the risk of clogging. The PAS centrifugal diesel open-frame pump range comprises ten models which include three high-flowmodels. Maximum flow capacity is 1 130 m 3 /h, with a maxi- mum head of 58,5 m and an outlet size of 100 to 300 mm. Eleven models make up the VAR centrif- ugal wet prime range. With an outlet size of 40 to 300 mm and a maximum head of 58 m, the VAR range delivers a maximum flow of 1 400 m 3 /h. Atlas Copco South Africa, tel (+27 11) 821-9000

The pioneering range of open-frame PAS dry and VAR wet self-priming centrifugal pumps from Atlas Copco Power Technique is said to deliver the perfect balance between performance, versatility, effi- ciency and portability. Over 140 years of industry experience combined with a sound understanding of customers’ needs from all around the world as well as the purchase of market- leading pump designer and manufacturer,

Varisco, are key factors that led to the development of the Atlas Copco dewater- ing range. Power Technique Business Line Manager, David Stanford, notes that Atlas Copco’s strategy, as a global leader in sus- tainable productivity solutions, is perfectly aligned to the pump industry. “Our primary focus is on providing effi- cient products which are better not only for our customers but also for the environ- ment,” he says. “To this end, we develop products that are smaller and lighter with features that deliver the easy use, move- ment and maintenance trio. Furthermore, we place emphasis on versatility to ensure that we can provide the best solution

appropriate for every industry that requires a pump solution from construction, general dewatering, wellpoint, sew- age by-pass and reservoir, pond and canal drainage applications to emergency use, such as flood clean up.”

In terms of versatil- ity, Stanford says the focus is on modular design ensuring that one pump is capable of covering multiple applications. The robust PAS and VAR pump systems

The patented components of the Latchways PRD fit neatly into the back- pack, allowing workers to carry out their daily tasks unhindered. Indeed, the back- pack becomes part of the daily Personal Protective Equipment (PPE) required for those working at height. In the event of a fall, the MSA Latchways PRD suspends the worker, who is then low- ered to the ground gently in a controlled descent. The device features a 20 m spool of Aramid rope, released at a controlled rate via an integral braking mechanism. The MSA Latchways PRD requires no specialist training, as it is simply worn in conjunction with a standard fully-body harness and is activated by simply pull- ing the release cord. Its user-friendliness is enhanced by the fact that pre-use checks are minimal.

ways Personal Rescue Device (PRD) integrated harness system from MSA Africa is a lightweight, unobtrusive rescue device con- tained in a small backpack, attached to a full-body harness. It has been designed to be used in conjunction with a fall protec- tion system or anchor point.
