    The "Duplex" oscillating piston pump is one
    of a range of new generation oscillating
    pumps of compact size which embodies
    design excellence coupled with outstanding
    performances and reliability.
    The "Duplex" pump designed for pumping
    liquids at low pressure and capacity, operates
    on the oscillating piston principle.
    Motion occurs when the coil is energized
    with unidirectional impulses created by an
    alternating current passing through a diode.
    Technical features
    and manufacturing characteristics

    threaded female 1/8" inlet and outlet ports,
    while the ball valves are in glass/EPDM.
    The piston working inside a metallic tube is
    in stainless steel.
    The pump may be mounted in any mode on
    shock absorbing supports for the best quiet
