The linear flow constant flow metering pump is a device that makes the liquid flow and output in a constant amount. It is the core part of various flow analysis equipment, which is equivalent to the human heart. The linear flow constant current metering pump has the characteristics of safety, accuracy, stability, durability, zero contact between the conveyed material and the outside world, continuously adjustable high pressure, high lift, etc. It is widely used in various pharmaceutical, chemical and petroleum refining industries. Its flow stability determines the key issues such as the yield of synthesis.

ZSMR's low-pulse linear constant-current pump adopts a patented cam curve, which truly achieves constant instantaneous flow rate in the sense. It has the characteristics of high output flow accuracy (±0.5%) and low pulse (±0.5%). The constant current pump can also maintain linear constant current when it is pressurized, which meets the requirements of high pressure and high precision in most practical applications. The control method adopts touch screen to realize human-computer interaction, which is convenient for users to adjust parameters.
