Diaphragm Buffer
HPD Series

A Key Equipment to Stabilize System Pressure Fluctuations and Extend Pump and Pipeline Life

The HPD Series is a diaphragm pulsation dampener that uses a top and bottom shell structure with a PTFE + rubber composite diaphragm separating the compressed gas from the conveyed liquid. It effectively absorbs pressure pulsations, achieving up to 90% pulsation suppression, making it an essential pressure stabilization solution for metering pumps and chemical transfer systems.

Product Features

• Gas-Liquid Separation Design, Stable and Durable Operation
  The diaphragm separates the gas and liquid inside, ensuring stable pressure even during prolonged operation. It is suitable for various metering and high-precision transfer applications.
• Highly Corrosion-Resistant Composite Diaphragm
  The wetted parts consist of the bottom shell and diaphragm. The standard diaphragm uses multi-directional rolled PTFE + rubber material, offering excellent corrosion resistance and long service life. A high-temperature-resistant PTFE + acrylate diaphragm is also available as an option.
  
• Protects the Entire System Equipment
  It reduces water hammer effects and flow velocity peak fluctuations, protecting pipelines, fittings, and valves from pressure shock damage.
• Improves Pump Efficiency and Reduces Energy Consumption
  It creates a stable pressure environment for metering pumps, improving output accuracy and operational efficiency. It can be paired with a backpressure valve to achieve near-pulsation-free delivery.
• Saves Pipeline Costs
  Stable pressure allows the use of smaller diameter pipes, saving material and system space costs.
