Quincy QCVDry Claw Solutions | Vacuum Pump

Quincy QCV

There is Always a Better Way.For nearly a century this guiding principle has driven Quincy Compressor engineers and designers to develop new technologies and revolutionize productivity in the compressed air and vacuum world. It is the driving force in everything we do, many of the group’s products have become global success stories. The innovation of a rotary screw vacuum pump with Variable Speed Drive delivering on average 50% energy savings, is one of them.

Successful companies bring innovative products that contribute to the productivity of their customers. Premium products are technologically more advanced. On the other hand a brilliant design that offers simplicity is also innovation. You should be offered a solution with the lowest cost of ownership. To score better than competition, innovation is key. What we want to achieve for you are lower life cycle costs, higher productivity, less energy consumption, simple operation, and easy maintenance.

That is also what we aimed for when designing our new QCV Dry Claw Vacuum Solutions: they stand for sustainable productivity.

Connect and EmpowerThousands of applications – central systems in hospitals, CNC routing, pneumatic conveying, milking parlors – share a common need: vacuum. And that is what Quincy Compressor provides — safely, reliably, cost-effectively and continuously. Connect with Quincy Compressor to get the utility you need to empower your processes and operations and drive your productivity.

Masters of InnovationThe durability of our QCV Claw Pumps is rooted in our expertise. We acquired Edwards, the company that first introduced claw technology to vacuum applications in the high tech electronics industry. The combined knowledge and experience of these two companies leads to low-cost, efficient and reliable products.

Fully Certified Our QCV Dry Claw machines meet the demanding requirements of ISO 9001, ISO 14001 and OHSAS 18001, as verified by Lloyds of London. They are backed by a market-leading warranty and a service support network. The result is 24/7 assurance that your products and your processes are constantly kept in the best possible working order.

The new range based on Quincy Compressor’s QCV Dry Claw technology features an innovative design which creates a new benchmark in the claw pump market. The simplicity, robustness, efficiency and contaminant-handling capability of these pumps make them the smart choice for your application. Built to the exacting standards and quality demanded by our customers, the new dry claw pump provides you with a trouble-free and cost-effective solution to meet your needs.

Built to LastManufactured on the fundamentals of Quincy’s compressor design, these pumps feature some innovative construction materials and coatings for a lifetime of reliable operation even in harsh conditions.

Easy Maintenance Long life bearings and seals, a separate and isolated pumping element, and the simplest of designs suited for quick access to the pumping chamber make for easy cleaning in the event of product carry-over.
