A reciprocating plunger type dosing pump is a positive displacement pump used to deliver precise and controlled amounts of chemicals or liquids in industrial applications such as water treatment, chemical processing, and power plants. It works by a plunger moving back and forth inside a cylinder, drawing in liquid during the suction stroke and discharging it under pressure during the forward stroke, which allows it to operate at high pressures with accurate flow rates. This pump is suitable for handling corrosive, abrasive, or viscous fluids, provides reliable and consistent dosing, and is ideal for processes that require exact chemical injection and high-pressure performance.

A gas-operated plunger type dosing pump is a high-pressure positive displacement pump that uses compressed gas, typically air or nitrogen, to drive a plunger for precise chemical or liquid injection in industrial applications such as water treatment, oil and gas, and chemical processing. The gas pressure moves the plunger back and forth inside a cylinder, creating suction and discharge strokes that allow accurate and consistent dosing even under varying system pressures. This pump is ideal for handling corrosive or hazardous chemicals, operates reliably without external electrical power, provides high-pressure performance, and ensures precise flow control for critical dosing applications.
