Parker / Hargraves DC12V Brushless Vacuum Pump Diaphragm Pump Dual Head Air Pump Parker / Hargraves DC12V Brushless Vacuum Pump Diaphragm Pump Dual Head Air Pump Introduction: BTC-IIS Miniature Diaphragm Pumps are brushless DC motor driven pumps which are tailored to meet the specific application performance requirements. The innovative compact designs incorporate leading edge technologies that allow them to operate more efficiently than existing pump designs. BTC-IIS Pumps offer multiple component configurations allowing them to be used for either vacuum, pressure, or alternating vacuum and pressure operations. BTC-IIS is ideal for compact, high flow, wide pressure ranges, long-life, low noise applications. Attention: This vacuum pump is used and may have signs of previous use on its exterior. However, this does not affect its functionality. We thoroughly test each unit, but please be cautious if you have any concerns before purchasing.
