Metering Pumps - Iwaki America
Metering pumps inject precise amounts of chemicals into water treatment, cleaning, food, oil and gas, and industrial processes. Accurate dosing controls costs and keeps product and water quality consistent.
Metering Pump Types
- Solenoid driven metering pumps – compact, low-flow dosing
- Motor driven metering pumps – higher flows and pressures
- Pneumatic metering pumps – hazardous and off-grid locations
Choosing a Metering Pump
Provide flow, pressure, chemical type, viscosity and control method. Choose compatible wetted materials and accessories like foot valves, injection valves, back pressure valves and calibration columns.
Centro supplies metering pumps and accessories for chemical feed systems.

- A metering pump is a dosing pump designed to deliver precise, repeatable amounts of fluid. It works by controlling stroke length, stroke speed, or motor speed to achieve accurate flow rates, even under changing pressure conditions.
- Common types include diaphragm metering pumps, piston metering pumps, peristaltic dosing pumps, solenoid driven pumps, and motor driven pumps. Each offers different benefits for pressure, chemical compatibility, and turndown ratio.
- Metering pumps are used in water treatment, chemical injection, cooling towers, boilers, food and beverage processing, pharmaceuticals, agriculture, and any application requiring precise dosing of chemicals or additives.
- To size a metering pump, determine required flow rate, discharge pressure, chemical type, temperature, viscosity, and desired turndown. It’s also essential to verify compatibility with seals, diaphragms, and wetted materials.
- Metering pumps can handle a wide range of chemicals including acids, caustics, polymers, disinfectants, coagulants, corrosion inhibitors, and food grade ingredients. Proper material selection ensures safe and reliable operation.
