Lightweight body supports submerged, wall-mounted and movable installation. Multi-port design is compatible with various piping systems for diverse layout arrangements.
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
● Lithium battery manufacturing industry
It can be used for conveying media including electrode slurry and electrolyte. The HP20 3/4 inch pneumatic diaphragm pump adopts pneumatic drive and generates no electric sparks during operation, satisfying the explosion-proof requirements of the factory. Low-shear conveying protects chemical properties of materials and delivers media gently and steadily.
● Fine chemical production field
Applicable to the transportation of strong acids, strong alkalis, organic solvents and high-viscosity chemical fluids. The HP20 durable air operated diaphragm pump effectively resists erosion from such fluids with corrosion and wear resistance, extending service life. It supports self-priming and dry running, matching intermittent production lines. Flow rate and pressure can be precisely regulated to realize on-demand production.
● Coatings and ink processing industry
Mainly applied to conveying color paste, raw paint and mixed liquid with solid particles. The HP20 3/4 inch pneumatic diaphragm pump can deliver particle-containing media and is not prone to blockage, ensuring continuous production. Tight sealing realizes zero leakage and eliminates material waste. Easy maintenance and simple operation lower time costs caused by equipment downtime.
FAQ
Q: The viscosity of conveyed materials varies, and fixed parameter settings cannot meet diverse conveying requirements.
A: The HP20 3/4" pneumatic diaphragm pump enables stepless and precise adjustment of pressure and flow by regulating air intake pressure and flow, adapting to the conveying conditions of materials with different viscosities. For low-viscosity fluids, reducing the air supply pressure and conveying speed realizes stable low-speed delivery. For high-viscosity liquids, appropriately increasing the air intake pressure boosts the power and conveying thrust of the pump, ensuring uniform and consistent material delivery.
Q: Complicated equipment maintenance and time-consuming downtime affect production progress.
A: The HP20 durable air operated diaphragm pump adopts an integrated modular split design, with independently arranged air valve components, flow parts and diaphragm assemblies for a neat and compact structure. Common faults such as material blockage and air valve jamming can be disassembled, replaced and maintained separately without removing the entire pump, which greatly simplifies the maintenance process. Equipped with an oil-free lubrication air valve, the pump operates smoothly without jamming and features a low failure rate.
Q: Long-term conveying of chemical media corrodes pump components and causes liquid leakage and pollution.
A: The pump body, flow parts, seals and other components of the HP20 3/4" pneumatic diaphragm pump are equipped with suitable anti-corrosion and wear-resistant materials according to the corrosion intensity of on-site conveyed fluids. The non-metallic design avoids metal contact, effectively preventing the erosion and oxidation of the pump body caused by acids, alkalis, organic solvents and slurries. The highly adaptive anti-corrosion internal structure features high stability and excellent chemical penetration resistance, keeping the internal pipeline smooth and unobstructed. It ensures stable conveying performance, reduces internal wall corrosion and component damage, and lowers the replacement and maintenance frequency of wearing parts.
