With only one moving part (a smooth-spinning centrifugal pump impeller), pumped venturi injection offers important benefits over reciprocating techniques like piston pumps and diaphragm pumps.
Metering and rate adjustment are easily done in real time, with direct indicating flowmeters showing the exact injection rate. No calibration procedure is necessary!
The smooth-running centrifugal pump is inherently less failure-prone than piston or diaphragm pumps. The simplicity of pumped venturi metering means a ChemIndustrial pump will continue performing long after other pumps are consigned to the breakdown bin.
ChemIndustrial pumped venturi metering pumps are competitive in initial cost with piston and diaphragm pumps for similar service and they enjoy significant price advantages in high capacity, medium pressure metering applications. They are usually more economical than peristaltic pumps, gear pumps and lobe pumps of similar capacities.
Even our basic metering pump models come preassembled, fully equipped and ready to run, including:
With smooth-running ChemIndustrial metering pumps, there’s no need for pulsation dampers, calibration kits, injection quills, injectate priming bleed valves or other extras.
ChemIndustrial builds versatile liquid chemical dosing systems to precisely inject liquids in most industrial, process and wastewater applications.
ChemIndustrial metering pumps inject a very wide range of chemicals, including:
Standard chemical contact materials include polypropylene, Viton® and Teflon®. Durable construction ensures low maintenance and dependable operation.
Other material options are used in some petrochemical, solvent and highly aggressive applications – check with a ChemIndustrial engineer for material options.
ChemIndustrial provides alternatives for special applications when a standard pumped venturi metering pump is not applicable.
ChemIndustrial’s custom systems expand on the capabilities of our standard metering systems. If you have an unusual metering requirement contact a ChemIndustrial engineer to determine whether a ChemIndustrial custom control system will be right for your process.
