A circulating pump is a type of pump designed to move liquids, gases, or slurries within a closed circuit to maintain a continuous, steady flow. These pumps are essential in systems where the fluid needs to be circulated through a loop or circuit, typically to ensure uniform temperature, pressure, or …
Illinois Process Equipment, IPE, offers metering pumps, also called dosing pumps as they are used to provide precision fluid handling and measured dosing of specific fluids. Fluid metering pumps deliver precise dosing while maintaining a constant flow rate to move a measured volume of liquid or chemicals over a specified …
Regenerative turbine pumps, also known as peripheral pumps or peripheral turbine pumps, are a type of centrifugal pump used for moving fluids, particularly in applications where high pressure and low flow rates are required. These pumps are known for their unique design, which sets them apart from other centrifugal pumps. …
Sulfuric acid pump selection requires more than matching the required flow rate to a pump curve. Chemical concentration, operating temperature, and transfer conditions all affect which materials and pump technologies suit the application. The same applies to sodium hydroxide and other caustic solutions. A pump that performs reliably at one …
You will learn how to evaluate chemical compatibility for metering pump liquid ends by checking the chemical, operating conditions, wetted materials, installation, and likely failure points.
Chemical feed pump redundancy should be based on the consequences of lost feed, not solely on the cost of adding another pump. In critical treatment systems, a single failed metering pump can create compliance exposure, product-quality problems, equipment protection risks, wastewater disruption, or unsafe process conditions. Redundancy can improve uptime, …
This infographic maps the common points where sodium hypochlorite systems fail, from suction lines and pump heads to seals, valves, and storage areas. It’s useful for maintenance teams and engineers troubleshooting chronic dosing problems.
A sodium hypochlorite metering pump must be selected for more than flow and pressure. Bleach and other off-gassing treatment chemicals can release gas in the liquid end, interfere with check-valve performance, and cause loss of prime even while the motor or solenoid continues to stroke. The result is usually seen …
Metering pump accessories determine whether the installed chemical feed system can verify output, protect against overpressure, control siphoning, reduce pressure spikes, and inject chemical into the process stream correctly. A metering pump may be sized correctly and still deliver poor results if the accessory package does not match the hydraulic …
Metering pump chemical compatibility starts with the liquid end, but the review cannot stop at the pump head. The diaphragm, check valves, seats, seals, tubing, calibration column, relief path, back-pressure valve, and injection assembly all contact the chemical. Any one of those components can become a weak point. A metering …
