We provide a wide range of dry vacuum pumps packaged as bare pumps, pre-engineered or engineered-to-order systems. Engineered-to-order systems are custom designed to meet customer process requirements. Pre-engineered packages are available for quick shipment with plug & play installation.
Our dry vacuum pumps operate contact-free. This means they do not require lubrication in the pumping chamber. Therefore, our dry vacuum systems operate without water, oil, or any other liquid. This results in major advantages like no process contamination or pollution caused by the pump operation.
NASH dry vacuum pumps & systems offer significant process and economic benefits. Dry technology provides lower installation expenses, easier maintenance, low running costs, and reduced environmental impact while providing a more flexible vacuum.
Our dry screw vacuum pumps & systems deliver a clean, oil-free vacuum for a variety of industrial applications. In these applications, our pumps perform with low rotational speed ensuring smooth and robust operation. Higher discharge pressure capabilities along with a high tolerance for vapor and dust guarantee more process time with long service life.
Our dry vacuum pumps & systems safely and reliably handle corrosives, organics, inorganics, and solvents. Thus, making NASH dry vacuum pumps & systems ideal for applications like degassing, vacuum metallurgy, vapor recovery, and central vacuum systems.
Since these applications require a clean, oil-free vacuum, our dry pumps serve the following market segments:
Furthermore, our dry vacuum pumps & systems have a wide operating range, low life-cycle costs, and long maintenance intervals. The wide operating range allows the pump to have limitless capacities with various backing pump options including high vacuum boosters.
NASH dry vacuum pumps operate from well below 0.1 torr up to atmospheric pressure. Low life-cycle costs and maintenance-free results in high efficiency and a reduction in energy and utility costs, as well as minimized operational downtime.
From clean and flexible operation to greater efficiency, dry systems can provide benefits over traditional wet systems.
