Series 4000

  • Hydaulically Actuated Diphragm

     
    The AQUFLOW® Series 4000 is a rugged, compact, hydraulically actuated diaphragm metering pump. The pump is available in simplex or duplex configuration, with independent capacity adjustment for each pumphead.
     
    All drive parts are fully enclosed and operate in an oil bath which minimizes friction and wear while providing protection from harsh environments. A self-compensating hydraulic system assures diaphragm position and eliminates the need for troublesome vacuum breakers and refill valve.
     
    The easy to read micrometer knob enables convenient capacity adjustment between 0-100% while the pump is operating or stopped. In addition to manual control, the pump can be supplied with optional automatic capacity control, making it possible for the pump to control the flow rate in proportion to various process signals. A simple, externally adjustable, internal hydraulic relief valve protects the pump and the process from pump induced overpressure situations.
