Solenoid Driven Metering Pumps
Solenoid driven metering pumps are precision devices used for accurate and controlled dispensing of fluids. These pumps utilize a solenoid-driven piston or diaphragm to deliver precise volumes of liquid, making them ideal for applications that require precise dosing, such as water treatment, chemical processing, and laboratory environments.
Motor Driven Metering Pumps
Motor-driven metering pumps deliver precise, reliable chemical dosing for demanding industrial applications, combining high flow capacity with consistent accuracy. Ideal for water treatment, chemical processing, and manufacturing, these pumps offer adjustable stroke length and motor speed to handle a wide range of fluid viscosities and pressures. Their robust construction ensures long-term durability, while optional features like integrated controllers and safety valves enhance process control and system protection.

FAQS
- 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.
