Parker's Miniature Diaphragm Pump Dual Head Models BTC-IIS & TTC-IIS have an industry leading performance to size ratio and can be configured to meet the most stringent flow, reliability, efficiency, size, and noise requirements.

Product Information

BTC-IIS & TTC-IIS Miniature Diaphragm Pumps are a series of brush and brushless DC motor driven pumps, which are tailored to meet the specific performance requirements of your applications and meet stringent gas tightness requirements. These pumps are designed to handle air and gases only. The innovative compact designs incorporate leading edge technologies that allow them to operate more efficiently than existing pump designs. All series offer mutliple component configurations allowing them to be used for either vacuum, pressure, or alternating vacuum and pressure operations. BTC-II pump is ideal for individual head specifications, high flow, and a wide range of pressure applications. BTC-IIS is ideal for compact, high flow, wide pressure ranges, long-life, low noise applications. TTC-IIS is best for high flow, lower pressure range, even more compact, and highly efficient applications.
