Metering Pump Suppliers and Importers in Pakistan
Mirha International premier supplier and importer of metering pumps in Pakistan, we specialize in delivering precise and reliable pumping solutions to a wide range of industries. Our metering pumps are engineered for accuracy and efficiency, making them ideal for applications in chemical processing, water treatment, pharmaceuticals, food and beverage, and more.
1. Diaphragm Metering Pumps
Description: Diaphragm metering pumps use a flexible diaphragm to create a pumping action. The diaphragm moves back and forth, creating a cavity that fills with liquid and then discharges it through a valve.
Applications:
- Chemical Dosing: Adding chemicals to water or other solutions.
- Water Treatment: Disinfectants and flocculants dosing.
- Food and Beverage: Precise ingredient dosing.
Key Features:
- High accuracy and repeatability.
- Capable of handling corrosive and abrasive chemicals.
- Adjustable flow rate.
- Self-priming capabilities.
2. Peristaltic (Hose) Metering Pumps
Description: Peristaltic metering pumps operate by compressing and releasing a flexible hose or tube using rotating rollers. This action moves the liquid through the hose in a controlled manner.
Applications:
- Chemical Transfer: For handling aggressive or shear-sensitive fluids.
- Food Processing: Sanitary and hygienic applications.
- Pharmaceuticals: Accurate dosing of sensitive liquids.
Key Features:
- Minimal contact with the fluid, reducing contamination risks.
- Easy maintenance with quick hose replacement.
- High accuracy and reliability.
3. Gear Metering Pumps
Description: Gear metering pumps use interlocking gears to move liquid through the pump. The liquid is trapped between the gears and carried from the inlet to the outlet.
Applications:
- Chemical Processing: Handling viscous and high-pressure fluids.
- Oil and Gas: Pumping lubricants and other fluids.
- Printing and Coatings: Accurate delivery of inks and coatings.
Key Features:
- High pressure and flow rate capabilities.
- Suitable for handling viscous fluids.
- Low pulsation and stable flow.
4. Piston Metering Pumps
Description: Piston metering pumps use a reciprocating piston to move fluid through the pump chamber. The piston moves back and forth, creating suction and pressure to pump the liquid.
Applications:
- Industrial Applications: Dosing of various chemicals and additives.
- Water Treatment: Disinfection and chemical injection.
- Food and Beverage: Precise addition of ingredients.
Key Features:
- High accuracy and repeatability.
- Suitable for high-pressure applications.
- Can handle a wide range of fluid viscosities.
5. Screw Metering Pumps
Description: Screw metering pumps use a rotating screw to move fluid through the pump. The screw action provides a smooth and continuous flow of liquid.
Applications:
- Chemical Injection: For accurate dosing in various industrial processes.
- Food Processing: Dosing of viscous food ingredients.
- Pharmaceuticals: Accurate dispensing of formulations.
Key Features:
- Consistent and smooth flow.
- Suitable for handling viscous and shear-sensitive fluids.
- High efficiency and minimal pulsation.
6. Diaphragm Metering Pumps (Hydraulic or Mechanical)
Description:
- Hydraulic Diaphragm Pumps: Use hydraulic fluid to drive the diaphragm movement. They are suitable for handling hazardous or high-pressure fluids.
- Mechanical Diaphragm Pumps: Use a mechanical drive mechanism to move the diaphragm.
Applications:
- Chemical Processing: For precise dosing of aggressive chemicals.
- Water Treatment: Injection of flocculants and disinfectants.
Key Features:
- High accuracy and reliability.
- Can handle a wide range of pressures and flow rates.
- Designed for various types of fluids.
Choosing the Right Metering Pump
When selecting a metering pump, consider the following factors:
- Flow Rate and Pressure Requirements: Ensure the pump can handle the desired flow and pressure.
- Fluid Characteristics: Viscosity, corrosiveness, and shear sensitivity of the fluid.
- Accuracy and Repeatability: Required precision for dosing applications.
- Maintenance Needs: Ease of servicing and part replacement.
