Gaodetec is a manufacturer of peristaltic metering pumps. We have more than 20 years of experience in research and development and manufacturing of peristaltic metering pumps. Next, we will briefly share some characteristics of peristaltic metering pumps to help you better choose the product that suits you.
 

1. Introduction of Peristaltic Metering Dosing Pump

It is a special volumetric pump that can meet the needs of various strict technological processes, and the flow can be adjusted steplessly within the range of 0-100%, which is used to transport liquids (especially corrosive liquids), also known as fixed-rate pumps or Pump. The metering pump is a reciprocating positive displacement pump for accurate metering. Generally, the stability accuracy of the metering pump is not more than ± 1%. The metering pump is also called a dosing pump or a proportional pump. The metering pump is a kind that can meet various strict process requirements. The more prominent feature is that it can maintain a constant flow independent of pressure. Metering pumps have been widely used in various industrial fields such as petrochemicals, pharmaceuticals, and food.
 

2. Working principle of peristaltic metering pump

The motor drives the worm through a coupling and decelerates the main shaft and the eccentric wheel to make eccentric movements through the deceleration of the turbine. The eccentric wheel drives the sliding adjustment seat of the bow link for reciprocating movement. When the plunger pump moves back to the dead point, the pump cavity gradually forms a vacuum, the suction valve opens, and the liquid is sucked; when the plunger moves forward to the dead point, the pump cavity gradually forms a vacuum. At this time, the suction valve closes, the discharge valve opens, and the liquid It is discharged when the plunger moves further forward, and the continuous and reciprocating operation of the peristaltic metering pump forms a continuous, pressured, quantitative discharge of liquid.
