What does '100% oil-free transfer' mean for my application?

This means the pump operates without oil in the gas path, preventing contamination of your samples or processes with oil vapours. It's crucial for sensitive applications.

Is this pump suitable for continuous operation?

Diaphragm pumps of this type are generally designed for continuous operation, offering reliable performance over extended periods in laboratory environments.

Can this pump handle corrosive gases?

This specific unit is described as suitable for 'slightly aggressive or corrosive gases and vapours'. For highly corrosive media, buyers should verify the exact wetted materials with the seller.

What kind of noise level can I expect?

Neuberger diaphragm pumps are typically designed to operate with a relatively low noise level, making them suitable for laboratory environments where noise can be a concern.

What accessories are typically needed for operation?

Typically, you would need appropriate tubing to connect to your application, and potentially a vacuum controller or pressure regulator depending on your specific process requirements.
