DN15-DN80 Cast Iron Pneumatic Diaphragm Pump YGSL
Head Range：0-70 m
Inlet/Outlet Range：DN15-DN80
Product Feature：Ingersoll Rand standard exit
Structural Advantages of the Diaphragm Water Pump
Dual Diaphragm Isolation
PTFE/EPDM diaphragms separate media from air systems, eliminating leakage of toxic/flammable liquids (e.g., liquefied gas, xylene).
Abrasion Resistance
Passes solids up to 12mm diameter, outperforming standard pneumatic diaphragm pumps in coal mine slurry extraction.
Air-Driven Simplicity
Adjust flow/pressure by regulating compressed air (0.3–0.7 MPa), avoiding complex electrical controls.
Dry-Run Protection
Automatic shutdown when fluid is depleted, preventing diaphragm damage (50% longer lifespan vs. mechanical pumps).
How Does a Diaphragm Pump Work?
Air Power
Compressed air enters the distribution valve, alternating pressure between diaphragm chambers.
Diaphragm Actuation
Discharge Phase: A diaphragm compresses, forcing fluid out through the discharge valve.
Suction Phase: The opposing diaphragm retracts, creating vacuum to draw in new fluid.
Valve Control
One-way ball valves ensure unidirectional flow, forming a continuous cycle.
Dual-Chamber Synchronization
Balanced air pressure reduces pulsation by 40%, ideal for sensitive diaphragm water pump applications (e.g., nuclear wastewater).
Key Applications of the Pneumatic Diaphragm Pump
Oil & Gas: Tanker unloading, refinery waste recovery (gasoline, diesel).
Mining & Tunneling: Coal slurry drainage (12mm solids), methane-contaminated wastewater extraction.
Nuclear Energy: Coolant circulation and radioactive wastewater handling
Municipal Emergencies: Flood control as a diaphragm water pump, urban sewage backup clearance.
