General Description
Positive displacement, Liquifram type, UL and CUL approved chemical metering pumps are required for the LMI Series C. Pumps operating at zero to maximum capacity must have changeable output volume.

Drive Assembly
All moving components of the pump drive must be completely enclosed. To ensure optimal protection against chemical spills, electronics must be kept inside a chemical-resistant enclosure located at the back of the pump. With maximum pressure and speed, the maximum amount of electrical power that can be consumed in an hour is 44 watts. The maximum pump weight is 20 pounds (9.1 kg).

Pump Controls
Adjustment shall be by means of readily accessible dial knobs, one for changing stroke length and the other for changing stroke frequency. Both knobs are to be located opposite the liquid handling end.

Pressure Relief
To eliminate need for pressure relief valve, Liquifram shall automatically stop pulsating when discharge pressure exceeds pump pressure rating by not more than 35%.

Materials of Construction
See Specifications tab. Chemical metering pump housing shall be of chemically resistant glass fiber reinforced thermoplastic with a glass fiber reinforced polypropylene EPU carrier. All exposed fasteners shall be stainless steel. Valve seat and seal ring shall be renewable by replacing only the combination seat-seal ring or cartridge valve assembly.

Check Valve, Tubing, Connections
A total of 16 ft (4.8 m) of tubing shall be provided per pump complete with compressing connections (on models with tubing connections). A foot valve with integral one piece strainer shall be provided for the suction line (on non-high viscosity models with tubing connections), and an injection check/back pressure valve with 1/2″ NPT male connection for the injection point (on models with tubing connections).

The long-term reliability and heavy-duty construction of the Series C pumps make them an ideal product for a variety of applications, such as:

  • Water Treatment
  • Waste Water Treatment
  • Industrial Processing
  • Agricultural
  • Chemical Processing
