Metering Pumps - Pulsatron/Pulsafeeder
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.
...
Solenoid driven metering pumps use an electromagnet to drive a diaphragm for precise, low-flow chemical dosing. They're compact, affordable and easy to control, which makes them the go-to choice for water treatment and cleaning chemicals.
Features
- Adjustable stroke rate and length – wide turndown
- External control – pulse, 4-20 mA and timer inputs
- Chemical-resistant heads – PVDF, PVC, PTFE and stainless
- Degassing heads – handle off-gassing chemicals
Choosing a Pump
Provide flow range, pressure, chemical and control method. Include foot valves, injection valves and calibration columns for accurate feed.
Centro supplies solenoid metering pumps for chemical dosing.

Motor-driven metering pumps deliver accurate, consistent dosing at higher flows and pressures than solenoid pumps. They're built for continuous duty in chemical processing, water treatment and oil and gas.
Pump Types
- Mechanical diaphragm pumps – simple, economical dosing
- Hydraulic diaphragm pumps – high pressure and accuracy
- Piston and plunger pumps – very high pressures
- Multiplex pumps – multiple chemicals from one drive
Choosing a Pump
Provide flow, pressure, chemical and control needs. Select materials and stroke control (manual, electronic or VFD).
Centro supplies motor-driven metering pumps and accessories.

- 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.
