  1. ATEX HDPE & PTFE Diaphragm Pump

    Tapflo’s ATEX HDPE & PTFE Diaphragm Pump is manufactured from solid block conductive (Carbon filled) plastic meaning it can be supplied for use within equipment group IIG (gas), Cat 2 (Zone 1).

    The conductive material ensures that no electrostatic loads will accumulate within the pump and the conductive pigments in the material reduce the surface resistance to less than 105 W, these pigments are what cause the black colouring.

    The colouring does not affect the chemical resistance of the thermoplastics. Diaphragms supplied can be PTFE with conductive back or EPDM which is conductive. The pump has an earth connection which earths electrostatic loads. This ATEX range is available across the full-size range of Tapflo HDPE & PTFE pumps.

    Tapflo’s TB Barrier Diaphragm Pump has been designed with an additional set of diaphragms used to support the primary diaphragms. It is the perfect solution for when a diaphragm rupture has to be detected immediately in order to avoid the product leaking into the environment and the air distribution system.

    When a rupture is detected the pump is automatically stopped and an alarm can be generated to alert you to the issue.
