INTRODUCTION
These installation, operation and maintenance instructions cover your electronic metering pump. Refer to the pump
nameplate to determine the actual model.
 PRINCIPLE OF OPERATION
Diaphragm metering pumps are used to dispense chemicals or fluids. This is achieved by an electromagnetic drive
mechanism (solenoid) which is connected to a diaphragm. When the solenoid is pulsed by the control circuit, it
displaces the diaphragm which, through the use of check valves, moves the fluid out the discharge under pressure.
When the solenoid is de-energized it returns the diaphragm and pulls more fluid into the pump head and the cycle
repeats.
The stroke rate of the pumps is controlled via the touchpad and present status is indicated by the LCD display. The
stroke length is controlled via the stroke length knob.
 MATERIALS OF CONSTRUCTION
The wetted materials (those parts that contact the solution being pumped) available for construction are Glass filled
polypropylene, PVC, SAN, Hypalon, Viton, PTFE, 316 Stainless Steel, PVDF, Ceramic and Alloy C. These materials
are very resistant to most chemicals. However, there are some chemicals, such as strong acids or organic solvents,
which cause deterioration of some elastomer and plastic parts, such as the diaphragm, valve seats, or head. Consult
Chemical Resistance Guide or Supplier for information on chemical compatibility.
Various manufacturers of plastics, elastomers and pumping equipment publish guidelines that aid in the selection of
wetted materials for pumping commercially available chemicals and chemical compounds. Two factors must always
be considered when using an elastomer or plastic part to pump chemicals. They are:
1. The temperature of service: Higher temperatures increase the effect of chemicals on wetted materials. The
increase varies with the material and the chemical being used. A material quite stable at room temperature
might be affected at higher temperatures.
2. Material choice: Materials with similar properties may differ greatly from one another in performance when
exposed to certain chemicals.
