be changed quickly via the maintenance cover, which is sealed by an O-ring or, for sizes 50-303, directly from the outside with a bayonet fitting. All pumps from50m³/hup featureagas ballast valve as standard. This optimises the water vapour tolerance and when the pump reaches its operating temperature, any water vapour passes through as gas, without condensing. Standard features of the VACFOX VC range include: vanes made from special alloy for long service life; oil separators with permanent oil re-circulation; gas bal- last valves fromrangeVC50 (50m³/h) and up; and oil mist filters with bayonet fixing (sizes VC 50 to VC 303). Air & Vacuum Technologies is an ap- pointed distributor for the entire Elmo- Rietschle range of products and spare parts. www.vactech.co.za

recently bolstered its pump rental fleet with the inclusion of Urban LED mobile tower lights. Units are mine-specific and comply with all safety requirements. Manufactured by AllightSykes, the Urban MLLED200K-9AC mobile tower light is built to the highest quality stan- dards ensuring reliable operation. The tower’s light, powder-coated full steel body and galvanised hydraulic mast The VACFOX VC range is based on three different designs: Compact pumps with overhung bearing design; Medium ranges with rotors supported on both sides using flexible couplings; and Large pumps with rotors supported on both sides, flexible coupling and double walled cylinders for improved heat dissipation. The VACFOX VC rotary vane vacuum pumps are air cooled in the standard version. An oil-water cooler is available for high ambient temperatures or for heat recovery. The exhaust air is cleaned by built-in oil mist filters with very high separation efficiency, ensuring oil free operation in all working conditions. During service, the oil mist filters can vacuum pumps for industrial coarse and fine vacuum operation.

Oil-lubricated rotary vane vacuumpumps designed and built by Elmo-Rietschle, in Germany, are used in a wide variety of industrial applications. Elmo-Rietschle offers the largest range of oil-flooded A filter view of the VACFOX VC 303 oil-flooded vacuum pump from Elmo-Rietschl.

LEDmobile tower lights available for rental

Lighting has a crucial role to play in al- lowing people to see clearly and avoid obstacles, obstructions, dangers and hazards. This is especially so when working on site, making lighting a critical safety issue. Lee Vine, managing director of Inte­ grated Pump Rental, says better light- ing also enhances productivity and in response to this demand the company

Integrated Pump Rental has added Urban LED mobile tower lights to its rental fleet.

SA’s master vibration analyst presents at IMVAC Condition monitoring specialist, WearCheck, invests in highly qualified and experienced scientists and techni- cians, whoundergo regular professional training courses to retain the company’s recognition as leaders inpreven- tive maintenance techniques. Dennis Swanepoel of WearCheck’s reliability solu- tions division in Johannesburg recently made history when he became the very firstMaster VibrationAnalyst in SouthAfricawhen he passed his CAT IVexamthrough the Mobius Institute. In June, Swanepoel was invited topresent twopapers in Antwerp, Belgium, to delegates who were attending the latest IMVAC (International Machine Vibration Analysis and Condition Monitoring Conference).

The Urban MLLED200K-9AC is equippedwitha9.0mmast, whichensures maximum output for reaching the work area to provide optimum productivity and safety. The 359° mast rotation with lightbar tilt capacity is standard. Powered by a Perkins engine, the 240 V ac tower lightdelivers200000lumensthroughfour powerful 500W LED lamps. The unit is equipped with four adjust- able outriggers, facilitating optimum stability in all underfoot conditions. “TheinclusionoftheUrbantowerlights in our rental fleet is a natural progression and is aimed at addressing customer needs,” Vine says, adding that they are also available for purchase. www.pumprental.co.za

WearCheck’s Dennis Swanepoel, SA’s first Master Vibration Analyst, was invited to present two papers to delegates at IMVAC in Belgium in June.

Swanepoel’s first paper, titled ‘Tried and Tested TubeMill Monitoring’, focused on tubemills used for coal milling in the power generation industry. Withmore than ten years’ experience in the field of tube milling applications, Swanepoel was able to discuss various special methods in the fields of oil analysis, vibration analysis, advanced signal processing, operational deflection shape analysis, thermal analysis and operational visual inspections. Paper 2, entitled ‘Is Video Amplification Real?’ discussed the analysis of two case studies where video amplificationwas used, and this datawas then compared to traditional operational deflection shape analysis. www.wearcheck.co.za
