Piston dosing pump

The piston dosing pump is a classic, robust, and highly durable type of dosing pump. Its design includes a cylindrical pumping chamber where a piston moves linearly to create volume changes within the chamber. This volume adjustment enables the precise control of liquid flow rate, which can be regulated by modifying the stroke length or the frequency of the piston’s motion. Due to their sturdy construction and powerful operation, piston dosing pumps are ideal for high-pressure systems, especially for liquids that are low in abrasiveness and do not require high sealing.

The Role of the Piston in Dosing Pumps

In this system, the piston serves as a replacement for the diaphragm found in other dosing pumps. The piston, shaped cylindrically, moves within the pumping chamber, creating a suction and discharge cycle for the liquid. As the piston moves, it changes the chamber’s volume, generating pressure variations that facilitate the steady and continuous transfer of chemicals or other liquids. One of the significant advantages of the piston dosing pump is its ability to adjust the flow rate without disrupting the suction and discharge cycle. This can be achieved by altering the frequency, stroke length, or piston speed. Additionally, increasing or decreasing the number of pumping heads also allows effective flow control.

Importance of Regular Inspection and Replacement of the Piston

Regular inspection and replacement of the piston in piston dosing pumps are essential to maintain optimal performance and extend equipment longevity. Over time, the piston endures significant pressure and friction from continuous movement within the chamber. These factors can lead to wear and tear, resulting in the following issues:
  • Reduced Pump Efficiency: Worn pistons and surrounding seals can decrease the pump’s sealing ability, which reduces the effectiveness of liquid suction and discharge, impacting the overall system’s operation.
  • Liquid Leakage: The seals surrounding the piston prevent leaks, maintaining pressure stability within the pump chamber. If these seals wear out, it can cause leaks, reduce pressure, and shorten the lifespan of other pump components due to chemical exposure.
  • Ensuring Dosing Accuracy: Piston dosing pumps require high precision to dispense the exact amount of liquid. Worn or ineffective pistons can compromise this accuracy, affecting production or chemical processing outcomes.
  • System Protection and Safety: Leakage or pressure fluctuations can lead to unexpected system failures, potentially damaging other components or creating safety risks, especially when handling hazardous chemicals.
