Advantages and Features
1. The 1.5 inch air operated diaphragm pump is purely pneumatically driven, with no motor and no risk of electric sparks, requiring no external power supply. It is perfectly suitable for flammable and explosive hazardous areas such as oil & gas, chemical and mining industries, serving as an ideal safe option for explosion-proof scenarios.
2. The HP40 1.5 inch air operated diaphragm pump delivers a maximum flow rate of 106 GPM (401 LPM) with excellent conveying performance. It efficiently completes high-flow fluid transfer, circulation and batching tasks, greatly improving production efficiency. Its modular design combined with an easy-maintenance structure reduces downtime and cuts operational and maintenance costs.
3. For pneumatic diaphragm pump for hazardous areas, the materials of the pump body and wetted parts can be selected according to actual working conditions, and matched with suitable ports to adapt to various solid-containing and viscous fluids such as coatings, oils and chemical media, meeting diversified production needs. The diaphragm pump adopts a shaft-seal-free and impeller-free structure, which is not easy to be blocked by impurities. It supports dry running and self-priming, and is available for intermittent medium conveying.
Complete System Installation Schematic
1. Air Source Treatment Unit
Filter Regulator ②: Filters impurities and moisture in compressed air first, then regulates and stabilizes the air pressure supplied to the pump.
Dryer ③: Further removes moisture from compressed air to prevent water vapor from entering the pump chamber and causing internal component corrosion and icing.
Lubricator ④: Atomizes lubricating oil and mixes it into compressed air to lubricate moving parts such as pneumatic valves and diaphragms of the pump and reduce wear.
Supporting components: Air Inlet, Check Valve, Shut-Off Valve.
2. Pump Body and Exhaust System
Pump Body: The core pneumatic diaphragm pump, which drives the diaphragm to move back and forth via compressed air to realize fluid suction and discharge.
Muffler: Installed at the pump exhaust port to reduce exhaust noise.
Piped Exhaust: Discharges waste gas to a safe area to avoid workshop environmental pollution.
Flexible Connection: A flexible connection between the pump and the air source treatment unit to buffer vibration and reduce stress transmission.
3. Fluid Suction Pipeline (Left Side of the Figure)
Suction: The starting point for fluid entering the system, connected to upstream liquid storage tanks or pipelines.
Shut-Off Valve: Cuts off fluid suction for convenient pump maintenance.
Compound Gauge: Monitors suction-side pressure to identify issues such as insufficient suction lift and pipeline blockage.
Flexible Connector: Absorbs pump vibration and prevents stress damage caused by rigid pipeline connection.
Drain Port: Drains residual liquid in the suction pipeline for maintenance or pipeline emptying.
Pipe Connection: Multiple connection types are optional to adapt to on-site pipeline conditions.
4. Fluid Discharge Pipeline (Right Side of the Figure)
Flexible Connector: Buffers pump vibration to protect pipelines and equipment.
Pipe Connection: Consistent with the suction end, adaptable to on-site pipelines.
Drain Port: Drains residual liquid in the discharge pipeline for maintenance and emptying.
Surge Suppressor ①: Stabilizes the pulsating discharge pressure of pneumatic diaphragm pumps and protects pipelines and downstream equipment, serving as a key accessory on the discharge side.
Pressure Gauge: Monitors discharge-side pressure to judge the operating status of the pump.
Shut-Off Valve: Cuts off fluid discharge to facilitate maintenance of the pump and downstream equipment.
Discharge: The terminal outlet of the system, connected to downstream pipelines and equipment.
Unregulated Air Supply to Surge Suppressor: Directly supplies unregulated compressed air to the surge suppressor, utilizing the compressibility of gas to absorb fluid pulsation.
Applications
