Special Features of Air Operated Double Diaphragm Pump

What stands our AODD pumps apart is their striking features. These functionalities and characteristics entitle us to be a prominent pneumatic diaphragm pump manufacturer in India.

  • The pumps can run dry indefinitely without damage.
  • No shaft seals or gland packing.
  • Infinitely variable flow & discharge pressure from 0 to pump’s maximum by adjusting air pressure. One pump can fit a broad spectrum of applications.
  • Gentle non-shearing action.
  • If the discharge is clogged or closed, the pump stops immediately; no power consumed, no heat, no wear – By opening discharge, the flow starts automatically.
  • Operates submerged or with flooded suction.
  • Self-priming from a dry start.
  • Pressure up to 100 PSI (7 bar.)
  • No close fitting, sliding or rotating parts can handle a wide variety of fluids with high solid content.
  • Low internal velocity reduces wear.
  • Quick assembly and disassembly with split clamp bands.
  • Capable of pumping at high temperatures.
  • Quiet, Steady discharge flow without the use of pulsation dampener.
  • Safe for use in explosive environments.
  • No electrical hazards or costly motor and control equipment needed.
  • No pressure relief or bypass.
