DMP - DIRECT DRIVE DIAPHRAGMS

Direct Diaphragm pumps may be used when the liquid containing small amounts of particles in suspension.

The Wet-End consists of the Head, Valves, Diaphragm, Hydraulic Chamber, Piston and Seals.

Wet-End, Head, Diaphragm and valves is connected to the gearbox via a connecting flange. The diaphragm is directly driven by the gearbox.

On request more than one head, Multiplex Pump, can be assemble to allow for proportional metering of different fluids or double the flow range of the pump.

Gravity assisted ball valves are a standard.

Standard connection to the valves are with male BSP threads or preferably by O-ring face sealing connections. Special flanged connections are also available on request.

 Standard Materials:

  • X  =  Head & Valves in S.S. AISI 316 / PTFE lined Diaphragm
    • Fluid Temperature 0C to 40C
  • P =  Head & Valves in PVC / PTFE lined Diaphragm
    • Fluid Temperature 0C to 40C

    Gearbox is a robust construction consisting of a single worm reduction gear. Adjustment of the pumped volume per stroke can be varied manually from 0-100%, whilst the pump is running or at rest, via a control knob which has an easy to read scale.

    Motors are standard IEC frames, 4 pole - IP55 - TEFC, mounted vertically to the gearbox via a close coupled B14 flange. Standard motors are available in 400V or 525V three as well as 230V single phase . On special request motors can be ordered with other specifications, including explosion proof.
