Dosing Pump for Water Treatment Plant

A dosing pump is a positive displacement pump designed to transport very Exact flow rates of a chemical or other material to a fluid flow. The mechanism of the industrial pump entails drawing a measured amount of fluid into the room and then injecting this quantity speed into the container being dosed. As a purpose, a dosing pump is designed to be dependable so once it is correctly installed; it must look after itself and not need considerable amounts of input. Dosing pumps are used for automating fluid circulation in several applications such as pharmaceutical water treatment plants.While the parts of a dosing device may vary depending upon the brand and application, the significant components based on principle and functionality can be summarized as:

dosing pump

  • Foot valve — A non-return valve connected to the suction point and put into the drum of the goods. It is kept at the base of the drum, and contains a Float Switch attached to it for checking product availability and alarming when the latter runs out.
  • Dosing Pump — Generally made corrosion resistant PVC, PE and other plastics, rubbers and even stainless steel.
  • The suction line attaches to its own inlet as a dosing line attaches to the suction point.
  • Dosing Line — Generally constructed from rigid PVC or PE tubing or a reinforced hose, this element may have an assortment of bleed, pressure relief or air release valves included to it.
  • Injector — A delivery nozzle which pushes out the exact flux of merchandise given by the dosing pump to the line. It is intended to overcome the strain of the dosing pump.

The product is released in pulses or flow rate. The non-return valve includes a self-actuated mechanism that prevents the liquid at the shipping line from moving up after the necessary regular rate is delivered or after the pump stop. The injector also guarantees that the item is delivered to the center of the flow as opposed to the side wall to prevent wastage of merchandise, for thorough mixing, and to prevent damaging the walls particularly when the fluids are acids or peroxides.Modern plants use control systems and applications to ensure the dosing pump is precise and to offer automation. SCADA systems and other fundamental control systems with sensors for pH, chlorine, and similar and variable rate control are utilised to this end.
