Exclusive West Coast Representative for

Sigma Series 1, 2 & 3 Motor Driven Metering Pumps:

PRINCIPLES OF OPERATION
The ProMinent Sigma Series pumps are motor-driven with a mechanically actuated diaphragm-type liquid end. The Sigma pumps are constructed with a corrosion resistant plastic outer housing. The Sigma/2 and 3 also have a rugged metal inner casing for components subjected to mechanical stress. The standard liquid end materials are PVDF or 316 stainless steel; both with PTFE seals. Sigma pumps are designed with a convex DEVELOPAN® diaphragm which seals to a concave curve in the liquid end. This allows for precise metering of media with various viscosites and reduces stress for long diaphragm life.

FEATURES AND BENEFITS

ANALOG INPUT:

  • 4-20 mA input signal can be custom scaled to suit process conditions
  • Direct imput signal, SCR or inverter not needed
  • Can be used for proportional control

ANALOG OUTPUT:

  • 4-20 mA output signal proportional to pump flow rate
  • Use with flow monitor to verify flow

CONTACT/PULSE INPUT:

  • Programmable multiplier/divider for proportional feed

CALIBRATION:

  • Calibrate to actual flow with LCD indication of pump flow
  • Displays capacity in gph or 1/h and totalized volume pumped
  • Easy field calibration

FIELDBUS INTERFACE:

  • PROFIBUS® DP option for remote monitoring, diagnostics and control

TIMER:

  • Integral programmable timer (i.e. daily, weekly, biweekly, weekend)
  • Change operation to vary dosage on a timed basis (i.e. peak/nonpeak usage times; to bleed gas from suction line; for shock dosing of chemical)
  • Run pump from different control signals (i.e. analog then contact)

ACCESS CODES:

  • Program codes to access settings; prevents unauthorized adjustments

 

TYPICAL APPLICATIONS:
  • pH Neutralization
  • Chlorination/De-chlorination
    • Disinfection
  • Cooling tower chemical injection
    • Boiler chemical feed
  • Polymer feed
    • Fertigation services
  • Water/wastewater treatment

  • BASIC VERSION
    The choice for simple, metering pump applications. The pumps may be operated manually by adjusting the stroke length knob (displacement per stroke) at a constant stroke frequency using a constant speed motor. Automatic control of displacement per stroke via analog (4-20 mA) or 3P signal is possible with optional motorized stroke positioning systems.
    CONTROL VERSION
    Sigma microprocessor controlled metering pumps are programmable and display informative data for monitoring, recording and tracking. Functions include digital setting of stroke frequency, batch delivery and external control by contact, pulse or analog signal. Displays include flow rate (gph or 1/h) and totalized flow (gallons or litres), cumulative stroke count, and stroke length adjustment. Options include remote monitoring, diagnostics, control (via fieldbus, analog, pulse and/or timer), access codes, fault/pacing relays, mA analog output, and flow monitoring, Control version pumps are supplied with an integral TEFC motor.
