Haskel International LLC Needle Valves - Low Pressure

The 500 Series Vacuum Pump features a Heavy –Duty Lubrication System that is designed to allow over 16 operating hours per one gallon of oil (that’s twice the operating hours of our competition!). The 500 Series includes an integral one gallon oil reservoir tank which houses a heavy-duty positive displacement pump. This positive displacement pump strategically pumps oil through four steel lines (as opposed to plastic) into the main body of the Vacuum Pump. The 500 Series Vacuum Pump also boasts an integral Air In-Take Filter designed to protect the Vacuum Pump in both, Vacuum and Pressure modes. The Air-Cooled design features a heavy-duty fan located on the drive end of the pump. When the Vacuum Pump is in operation, the fan rotates to help keep the pump cool. All Vacuum Pumps include a 4-way Valve (Upper or Side Mount) allowing the operator to easily make the change from one mode (Vacuum /Pressure) to the other. Additional design features include; Vane Test Gauging Ports, Hand tightened Vented Breather Cap, Housing Drain, and 8 Vane Design for low washboard. The 500 Series Vacuum Pumps is designed to be converted into any drive style including, Belt, Right-Angle, and Hydraulic Drive.
