Elmo Rietschle unveils new oil-free claw vacuum pump

Developed in response to customer demand, the C-VLR 62 and 122 models are an extension to Elmo Rietschle’s already extensive portfolio of claw vacuum pump, ranging from 60 m³/h to 1000 m³/h.

For sites with limited plant space, the range has up to a 35 per cent smaller footprint than other existing claw vacuum pumps on the market. The new claw technology offers IE3 motors as standard, that are VSD compatible, adding extra controllability and helping to improve energy efficiency.

Maintenance intervals and costs are significantly decreased, with only minor oil changes required every 20,000 hours, instead of typically every 5,000 hours on oil lubricated pumps. Innovative design allows operators easy access to the pumping chamber for fast maintenance, resulting in less downtime for the customer. It also features a lower number of moving parts than competitor models, and with no sealing or lubrication fluids needed in the pump’s compression chamber, it is a very environmentally-friendly product. These benefits add up to an extremely low life cost solutions for vacuum pumps and a reduction in carbon footprint.

Delivering best-in-class noise levels, the technology features a sound insulation cover and exhaust silencer, eliminating the need for customers to invest in additional sound-proofing.

Christian Frank, Product Manager at Gardner Denver, said: “The C-VLR 62 and 122 are also available in both CD and XD models, covering ‘classic duty’ coating versions and heavy-duty units, offering businesses the best machine for their needs. For example, the XD range includes ‘ProCoat’, a protective coating that safeguards against harsh processes, such as vacuum sewage systems and milking, offering greater reliability when compared with existing claw pumps.

“Compact, quiet and oil-free, our latest vacuum solutions can dramatically cut energy costs for operators. For instance, the C-VLR 62 with active cooling can improve performance by up to 50 per cent when compared with existing models, saving operators up to €500 in the process.

“Both variants also offer passive or active cooling capabilities, depending on your requirements around the operating pressure level. Suitable passive cooling applications include pneumatic conveying, whereas active cooling is more appropriate for uses such as ‘pick and place’. Essentially, whatever your application, we have a vacuum solution that can help.”
