Features of FF / FF-H series

  • The FF series is designed for use with medium temperature liquids (Al cylinder type: 5 to 100˚C, PVC cylinder type: 5 to 50˚C) and the FF-H series is designed for temperatures ranging from 20 to 180˚.
  • All liquid contact components are constructed of high purity fluororesin materials with no metal or elastomers. The bellows are welded to the center eliminating leaks associated with heat cycles. The efficient design minimizes dead air volume surrounding the bellows to minimize air consumption.
  • Suction and discharge fluid connections are PFA tubes and for FF models PFA tubes with special fittings are available.
  • The pump utilizes a built in proximity sensor driven control system to switch an external air solenoid valve. Leak sensors are also included as standard equipment.
