Metering dosing pump

metering pump, also known as a dosing pump or proportional pump, is a volumetric
pump capable of precise flow control through stroke or frequency adjustment. It is
primarily used in industries such as petrochemicals, pharmaceuticals, and water
treatment for the quantitative dosing of corrosive media or chemical additives. Its
core function is to deliver liquid flow independently of pressure, with a metering
accuracy of up to ±1%.
The pump consists of a motor, transmission box, and cylinder body, driving the
plunger's reciprocating motion via a worm gear mechanism. Adjusting the stroke
length enables 0-100% stepless flow regulation. It is classified into plunger-type,
mechanical diaphragm-type, and hydraulic diaphragm-type designs, with the
diaphragm-type offering complete leak-proof functionality. It supports variable
frequency control, automatic signal input (e.g., 4-20mA), and multi-pump linkage to
meet mixing ratio requirements. Typical parameters include flow rates of 0.1-20,000
L/h, maximum pressure up to 64 MPa, and a medium temperature range of -30°C to
450°C. Pump head materials include PVC, stainless steel, PVDF, and others
