Working Mechanism

  • A motor drives a crankshaft / camshaft that moves connecting rods back and forth.
  • Rubber or plastic diaphragms attach the connecting rods to the diaphragms.
  • As the diaphragms move back and forth, a pumping action is created that moves the fluid through the pump.
  • Then the fluid enters the pump through an inlet port and is trapped between the two diaphragms.
  • As the diaphragms move back and forth, the fluid is forced through the outlet port.
  • The pump is then adjusted to vary the pressure and flow rate by adjusting the speed of the motor / by changing the inlet and outlet ports' size.

Features

  • These ARO diaphragm pumps are equipped with Viton / neoprene / nitrile / PTFE / Santoprene diaphragms for excellent thermal stability and abrasion resistance.
  • They feature polypropylene / stainless steel / aluminium body construction for structural rigidity and resisting corrosion on exposed surfaces.
  • They further feature an unbalanced air valve design that ensures ice-free, stall-free operation.
  • These ARO diaphragm pumps are equipped with a pneumatic motor for use in potentially explosive areas.

Standards and Approvals

  • ATEX
