    Harwil CF-112 Chemical Feed Pump Controller

    Manufacturer Series
    Harwil CF-112

    Harwil® type CF-112 chemical feed pump controllers are stand alone interface modules that automatically actuate a chemical feed pump when primary bulk fluid begins to flow. These modules can be used in isolated stand alone systems or as part of large complex systems. Typical uses are for metering and/or adding chemicals in both continuous and batch fluid systems such as: well water, drinking water, waste fluid processing, cooling tower pH/orp control, metal plating make up solutions, and boiler treatment additives.

  • harwill21nswitch_large

    Harwil L-21N/L-21VCR Level Switch

    Item Type Moving or Non-Moving Parts Technology Body Material
    Industrial, OEM Moving Parts Float Plastic

     

    Harwil® type L-21N & L-21VCR industrial level switches are low cost, high performance switches made from highly durable plastics. They feature a variable liquid differential and a single point pump up/pump down level control. Interchangeable differential band modules, for all non L-21+ versions, allow for 5 minute on-site switching of differentials from 1″ to 2″ to 3″ to 5″ in any sequence to satisfy variable operational requirements as they occur.

  • harwill30nswitch_large

    Harwil L-30N/L-30CR Level Switch

    Item Type Moving or Non-Moving Parts Technology Body Material
    Industrial Moving Parts Float Plastic

     

    Harwil® type L-30N & L-30CR industrial level switches provide particle contamination resistance via a single convolute elastomeric flexible seal which is continuously flushed by the working fluid. These switches feature vertical or horizontal mounting, high/low liquid level alarms, pump up/pump down controls, solenoid valve controls, liquid level indication, and an optional filter boot.

  • harwill40nswitch_large

    Harwil L-40N/L40VCR Level Switch

    Item Type Moving or Non-Moving Parts Technology Body Material
    OEM Moving Parts Float Plastic

    Harwil® type L-40N & L-40VCR side and top mount switches are made of corrosion resistant plastic with an optional metal pin available in 316 stainless steel, Hastelloy C, titanium, Tantalum, or Teflon. They are ten times less sensitive from deposit and build-up of contaminants than sliding float models and are meant for use in particle contaminated fluids.

    Harwil L-5/L-5SS Level Switch

    Item Type Moving or Non-Moving Parts Technology Body Material
    Industrial Moving Parts Float Brass/Bronze, Stainless Steel

     

    Harwil® type L-5 & L-5SS industrial level switches feature continuously adjustable float buoyancy control to allow use in fluids with specific gravity down to 0.6. Continuous buoyancy control allows switch activation at oil/water interface. These switches may be used in hazardous areas when used with intrinsically safe relays. They feature a high/low liquid level alarm, solenoid valve on/off control, and horizontal mounting.
