Special metering pump applications

ChemIndustrial provides the following alternatives for special applications when a standard pumped venturi metering pump is not applicable:

• Proportional injectors: Injecting chemicals at a constant percentage of a changing main flow is difficult to do accurately with piston and diaphragm pumps because of the pulsing flows they deliver. But ChemIndustrial's pumped venturi injectors are well-suited to the task. Our proportional injection controls make the injection rate respond to flow changes in the pacing stream for true flow-following injection. Integrated electronics allow automated or manual operation. The LCD user interface and touchpad are clear and intuitive.
   
• Fixed flow centrifugal pumps: ChemIndustrial combines centrifugal pumps with proprietary flow regulating devices to deliver consistant quantities of liquids over a wide range of process line pressures, effectively locking the pump output to an exact working point on its pressure/flow curve.
   
• Multiflow injectors: For operations injecting more than one material simultaneously, dramatic economies of operation and control are possible with ChemIndustrial's multiflow injectors.

Explosion-proof injectors are used with flammable injectates and in specialized process settings. Be sure to tell us early in the discussion if your process has XP requirements.   Engine-powered injectors: ChemIndustrial has a great deal of experience powering metering pump systems with internal combustion engines running on gasoline, diesel and propane. Most of our engine powered injectors are equipped with rugged, reliable Honda 4-stroke overhead valve gasoline engines. Pull start and electric start models are available with or without run timers. We even build engine driven metering systems with computer controls and automatic start-stop protocols. Call ChemIndustrial when you need metering pump systems for mobile use or where electric service is not available.   Mobile injector systems: ChemIndustrial provides self-contained trailer-mounted electric or engine powered injection systems for shared use among multiple sites. Trailer systems can be provided in off-road or highway configurations and often include mix tank(s).   Portable injectors: Most ChemIndustrial injectors can be equipped with heavy-duty wheels and handles for easy portability to multiple locations throughout a plant or site.
