A dosing pump is a type of positive displacement pump used to accurately meter and dispense fluids. The pump operates by using a piston or diaphragm to create a pulsating flow of fluid, which is controlled by a set of valves.

The valve plate and cylinder are two key components of a dosing pump that work together to control the flow of fluid through the pump. The cylinder is the main housing of the pump, and it contains the piston or diaphragm that moves back and forth to create the pumping action. The valve plate is a thin, circular plate that is located at the bottom of the cylinder and contains a series of ports and channels that control the flow of fluid into and out of the pump.
As the piston or diaphragm moves back and forth in the cylinder, it alternately compresses and expands the fluid in the pump, creating a pulsating flow. The valve plate controls the flow of fluid by opening and closing specific ports and channels at the appropriate times in the pumping cycle. This ensures that the fluid is dispensed in precise and accurate doses, which is critical in many applications such as chemical dosing, water treatment, and food processing.
The materials used to manufacture dosing pump valve plates and cylinders are typically high-strength metals such as stainless steel, which can withstand the corrosive and abrasive properties of many fluids. The valve plate is carefully designed and machined to ensure precise alignment and sealing between the various components of the pump.
