Chemical Injection System With Flow Meter

Model: WY-250CH-J1

Share to


Low-pulse chemical injection pump for injection of various chemical reagents. The air-driven hydraulic pump is used as the injection power source, and the injection pressure and the injection flow rate can be adjusted infinitely.

The equipment is equipped with an explosion-proof electronic flowmeter according to the flow rate, which can record and display the amount of chemical reagent injection for a certain period of time, and is especially suitable for occasions where the injection amount is strict.


Chemical Injection System With Flow Meter
  • ●  Low-pressure compressed air as the booster power source, safe and environmentally friendly.
  • ●  The flowmeter uses a lithium battery, which can display real-time and cumulative flow rate, and is designed to be explosion-proof and safe to use.Pressure self-locking function, under the condition of setting the driving air pressure, the output pressure is constant.
  • ●  Dual scale shockproof pressure gauge display.
  • ●  Infinitely variable output pressure and flow.
  • ●  Holds static pressure without generating heat or consuming power.
  • ●  No heat, flame or risk of spark.
  • ●  Well proven and trouble-free operation.
  • ●  Designed for ease of maintenance.
  • ●  Low cost servicing.
  • ●  Compact, robust, self-contained structure.
