A precision instrument designed for continuous constant‑speed, fixed‑volume delivery of small‑flow liquids under atmospheric or high‑pressure conditions. It is mainly used for quantitative delivery of liquid media in laboratories of universities and research institutes.

The DP series is designed to deliver fixed quantities at a low and steady flowrate. It finds application in feeding micro and small reaction devices such as high-precision catalyst evaluation devices, and microreactors. It is widely used in petrochemical, chemical, environmental protection, medicine and other fields.

Special Features
● Has four pre-set modes: constant flow, constant pressure, fix time, fix volume.
● 3.5 Inches display screen, displaying all the essential values such as flowrate, pressure, total volume, total time.
● Integrated leakage sensor below the pump head, alrm in case of leakage.
● Automatic stop when the pressure exceeds the pre-set (or input) max pressure.
● Built-in flowrate correction mechanism, set between 85~115% of the input flowrate.
● Each and every pump is checked for all the specification parameters.
● Multiple communication ports, allows for stand alone control, from PC, and from workstation.
