What is chemical dosing pump?

Chemical/metering dosing pump is a volumetric chemical dosing system that can change capacity manually or automatically as required by process conditions about 90% of all pumps sold are transfer pumps, used to move liquids from point a to point b. metering pumps designed for precise injection of chemicals, acids, bases corrosive or viscous liquid, and slurries. Metering pumps are needed for applications where one or more conditions exist.

  • High system pressure
  • Requires high precision feed rate
  • Requires low flow rate (ml/hr or GPH)
  • Requires pumping of viscous fluids or slurries
  • Handles corrosive, dangerous, or high-temperature fluids
  • Variable flow rate must be controlled by a computer, microprocessor, DCS, or PLC

How does a chemical metering pump work?

The pump motor drives a piston to produce a vacuum that draws the chemical from the external tank of the metering pump into the liquid end. Interspersing piston strokes produce pressure that closes the bay stopcock and opens the outlet stopcock, forcing the chemical into the process. There’s a diaphragm at the liquid end that acts as a hedge between the piston and the process fluid.

Occasionally the diaphragm is mechanically connected to the piston. Occasionally the diaphragm is hydraulically connected. the pumping stir of the piston is applied to the hydraulic fluid, and the diaphragm bends back and forth as the piston reciprocates. the movement of the piston bends the diaphragm – the more the diaphragm bends, the advanced the inflow rate of the pump. the inflow rate can be precisely controlled to ensure that the process receives what it needs and that there’s no over/ under injection.

Types of dosing pumps

Metering pumps are available in a variety of types and sizes. Whether they are used in food processing applications, manufacturing plants, or anywhere else where liquids need to be pumped in constant and precise amounts, there is a metering pump that is perfect for the job. The four conventional metering pump types are designed for different pressures, chemicals, and applications. They vary by pumping action and mechanism:

  • Diaphragm (constant injection) pumps use diaphragms, pistons, and valves at the inlet and outlet to fill and empty their chambers. The pumping of the piston fills the chamber and injects a specific amount of chemical at a preset rate, usually as a percentage of the maximum flow rate. Some pump models are capable of varying the dose rate.
  • Diaphragm (pulse jet) pumps also use a diaphragm mechanism, but instead of a constant flow rate, a solenoid coil draws in the chemical and injects it in pulses. The flow rate is the length of time between pulses. It is not as accurate as a constant injection pump, but the design is simple and inexpensive.
  • Lobe pump A pump that allows a certain volume of fluid to pass through a meshed gear impeller. It is not as accurate as a diaphragm pump and is only suitable for high viscosity fluids that have a self-lubricating effect to minimize wear. They are not made for low flow rates, as it is difficult to ensure accuracy.
  • Peristaltic pumps are very accurate in metering. The flexible bent tube allows the fluid to pass through and the flow rate is controlled by a roller, which is moved by an external robotic arm. This pushes the product in the tube into the metering tube and the main fluid stream.

Parts of a Chemical Dosing System

Main components of a dosing pump include:

  • Chemical vessel or tank – holds the product to be dosed.
  • Pump-Various materials and sizes; including inlet, suction, and dosing tubes.
  • Injector-a one-way valve into which the chemical is injected into the product; overcomes the pressure in the piping and allows the chemical to enter the liquid flow.
  • Bottom valve-a one-way valve attached to the suction line; placed inside the product drum to keep the pump in the starting position.
  • Dosing line – rigid or reinforced hose; can be PE, PVC, or stainless steel for high-pressure use.
  • Control system – ensures accuracy; opens and closes at specific times. Can be a simple flow switch or timer, to a variety of sensors for SCADA central control systems, and can be integrated into a larger system.
