Metering Pump

Metering Pump , also known as a chemical dosing pump, is a device designed to dispense liquids with high precision. Its flow rate can be adjusted according to specific requirements, making it a popular choice in industries requiring consistent liquid dosing, such as chemical additives or solutions.

Ligao chemical dosing pumps have gained popularity recently due to excellent customer feedback, superior design, and outstanding performance. Supported by a professional engineering team providing accurate usage consultations, Ligao pumps are widely trusted by various factories.

Notably, NITITAN Company has been officially appointed as a partner under the name LIGAO THAILAND, further enhancing their credibility in the market.

 

Type of Metering Pump

Soleniod Metering 

  • It is a liquid dosing pump powered by an electromagnetic solenoid (Solenoid), utilizing the movement of a diaphragm to suction and dispense liquids with high precision. This type of pump is ideal for applications requiring easy and accurate dosing control.

Advantages

  • High precision
  • Compact size and easy installation
  • Simple operational adjustments
  • Energy-efficient
  • Compatible with various chemicals
  • Easy maintenance
  • Low cost

Mechanical Metering 
A liquid dosing pump powered by mechanical mechanisms, such as an electric motor or gear system, which drives a diaphragm or plunger to accurately suction and dispense liquids.

Advantages

  • Simple and straightforward design
  • High precision
  • Compatible with various types of liquids
  • Durable and robust
  • Cost-effective
  • Suitable for low-pressure applications

Plunger Type 
A high-performance pump designed for precise liquid dosing, utilizing a plunger as its primary operating mechanism.

Advantages

  • High precision
  • Capable of handling high pressure
  • Robust construction
  • Compatible with a wide range of liquids
  • Energy-efficient

Hydraulic Type
A liquid dosing pump that utilizes a hydraulic system to control precise liquid dispensing. It employs hydraulic pressure to drive a diaphragm (in diaphragm models) or a plunger (in plunger models) for continuous and steady liquid suction and discharge.

Advantages

  • High precision
  • Excellent pressure handling
  • Compatible with a wide range of chemicals
  • Continuous and stable operation
  • Suitable for viscous liquids
  • Durable, robust, and easy to maintain

Metering Pump Head Materials

The pump heads for metering pumps are available in various materials to suit different applications:

  1. PVC (Poly Plastic)

    • Properties: Strong, durable, and moderately resistant to chemical corrosion.
    • Applications: Suitable for chemicals like alum, lime, chlorine, hydrochloric acid, and caustic soda.
  2. PVDF (Polyvinylidene Fluoride, also known as Teflon)

    • Properties: Tough, smooth surface, highly resistant to corrosion, and can withstand temperatures up to approximately 170°C.
    • Applications: Ideal for handling highly corrosive chemicals such as sulfuric acid, nitric acid, and hydrofluoric acid.
  3. Stainless Steel 304

    • Properties: Non-rusting metal, strong, smooth surface, and can withstand temperatures up to approximately 200°C.
    • Applications: Commonly used for chemical mixtures in pharmaceuticals, cosmetics, and some food-grade components.
  4. Stainless Steel 316

    • Properties: 100% rust-proof metal, robust, and can withstand temperatures up to approximately 200-250°C.
    • Applications: Primarily used for food-related industries, such as food additives, liquid detergents, syrups, and heated vegetable oils.
