The metering pump, also known as the proportional pump, is realized by conveniently and accurately adjusting the eccentric distance of the eccentric wheel to change the stroke of the plug when the liquid delivery volume is changed.

Metering pump is also called quantitative pump or proportional pump. Metering pump is a positive displacement pump which can meet the needs of various strict technological processes, and the flow can be adjusted steplessly in the range of 0-99%.

Metering pump is a kind of fluid conveying machinery. Its outstanding feature is that it can maintain a constant flow independent of discharge pressure. The metering pump can complete the functions of conveying, metering and regulation at the same time, so as to simplify the production process. Using multiple metering pumps, several media can be input into the process flow in accurate proportion for mixing. Because of its outstanding, metering pump has been widely used in petrochemical, pharmaceutical, food and other industrial fields.

working principle

The motor drives the worm through the coupling and decelerates the worm gear to make the main shaft and the eccentric wheel rotate, and the eccentric wheel drives the sliding adjusting seat of the bow connecting rod to make reciprocating motion. When the plunger moves backward to the dead center, a vacuum is gradually formed in the pump chamber, and the suction valve is opened to suck in liquid; When the plunger moves forward to the dead center, the suction valve is closed, the discharge valve is opened, and the liquid is discharged when the plunger moves further. In the reciprocating cycle of the pump, continuous pressure and quantitative discharge of liquid are formed.

Characteristics of pump

1. The pump has superior performance, in which the diaphragm metering pump has no leakage, high safety performance, accurate metering and transportation, the flow can be adjusted arbitrarily from zero to the rated value, and the pressure can be selected arbitrarily from normal pressure to the allowable range.

2. It has the advantages of intuitive and clear adjustment, stable operation, no noise, small volume, light weight and convenient maintenance. It can be used in parallel.
