Product Description

The BrandTech 110V Scientific rotary vane (oil) vacuum pump RZ series has a dual-stage pump, 2 x 10-3 millibar (mbar) ultimate vacuum, a flowrate of 1.6, 4.0, or 6.0 cubic feet per minute (cfm), depending upon model, and a compact body with nitrogen plasma-treated parts. A rotary vane vacuum pump is used in a variety of lab applications with freeze dryers or benchtop centrifugal concentrators, for low-temperature evaporations of high boiling point solvents, molecular distillations, schlenk lines, and other applications where diaphragm pumps cannot provide sufficient vacuum.

This dual-stage pump is used for high boiling point solvents, such as Dimethyl sulfoxide (DMSO). It is lightweight and compact, saving bench or floor space. Its nitrogen plasma-treated parts resist corrosion. Low rotation speeds reduce vibration and noise, and lower the pump temperature. An integrated gas ballast provides water vapor tolerance with low impact on ultimate vacuum. This pump provides continuous flow rates down to the pump’s ultimate vacuum, and performs well when pumping non-aggressive and non-corrosive gases in applications requiring deep vacuum levels.

Pumps evacuate an enclosed area and move a substance from one location to another. Pump choices are guided by the specific application and required substance compatibility. Diaphragm vacuum pumps (also called membrane pumps) are used in industrial and laboratory settings such as chemical analysis labs, water treatment facilities, and oil refineries. Diaphragm pumps expand and contract an interior diaphragm in order to draw a substance into the pump on one stroke and discharge it on the next stroke. The diaphragm forms an oil-free chamber that isolates the medium from the pumping mechanism, making diaphragm pumps a good choice when contamination is a concern. Ultimate vacuum is the deepest level of vacuum a pump can achieve. Flow rate (also called pumping speed) is a measure of the volume and speed at which a substance is drawn into a pump at its inlet. Compared to a similarly rated single-head pump, a pump with multiple pump heads connected in series will have a lower ultimate vacuum, and a pump with multiple pump heads connected in parallel will offer higher flow rates. A pump can have a mixture of pump heads that are connected in series and parallel, providing both improved vacuum levels and higher flow rates. Back pressure is a measure of the resistance at the outlet of the pump and can be damaging to the pump. Diaphragm pumps have constant flow rates regardless of the vacuum level, but as the vacuum pressure drops, the amount of mass moved through the pump decreases.
