Oil-free vacuum pump 7149

220VACsingle-stagecalibration

The 7149 is a vacuum pump for use with CalBenches and pressure calibration instruments. The pump is oil-less and features a shaded-pole, fan-cooled motor with thermal overload protection. The unit has dual pump heads that are connected in series for greater vacuum. It is an efficient and reliable vacuum source for testing applications. When used with CalBench systems, the 7149-HCO option provides an ergonomic enclosure, and connection from pump to CalBench console. It provides a compact housing for the pump, designed to be situated at the rear lower section of the CalBench system. It decreases the standard noise of the pump to less than 30 dB so the pump is extremely quiet and not noticible when running in the workshop environment. This is made possible by the sound proof materials used in the housing. Additionally the unit is mounted on four anti-vibration feet and the vacuum pump is internally fitted with shock absorbing mounts. For output connection the 7149-HCO is fitted with a quick release port on the side of the enclosure, with hose supplied for connection to the rear of the CalBench console. For power, a mains cable connects directly from the enclosure to the CalBench console rear input power socket. This is internally wired to the 7082 module, then a switch dedicated to turning the vacuum pump on or off is accessible via the front panel.
