Diaphragm Dosing Pump Hydraulically Actuated (HD Series)

The HD Series Hydraulic Diaphragm Dosing Pump is a highly efficient and reliable chemical dosing solution widely used in industrial applications, especially in water treatment plants. This diaphragm metering pump operates by using hydraulic fluid to actuate the diaphragm, ensuring precise and leak-free dosing of chemicals. Known for its ability to handle corrosive and hazardous substances, the HD Series guarantees accurate control of fluid flow even in demanding environments. Its hydraulic actuation enables smooth operation under high-pressure conditions, making it the ideal choice for critical water treatment processes where exact chemical dosing is essential.


Features:

  • Glandless design and entirely leak- proof operation
  • Flow rate is linear to stroke length variation
  • Metering Accuracy almost independent of back pressure
  • Automatic air bleeding from the hydraulic oil ensures better metering accuracy
  • Arrangement of in- built pressure relief valve protects the pump when pressure exceeds the rated limit.
