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.

FAQ
Q: Concerns that frequent production line adjustments and equipment relocation may cause loose pipeline connections and unstable pump operation.
A: After selecting the HNDP25 high-viscosity pneumatic diaphragm pump, we can design a reasonable layout for the pump and pipelines according to actual on-site working conditions. Featuring a compact structure and easy disassembly, the pump supports rapid relocation and layout adjustment. In addition, fastening the pipeline interfaces after each relocation ensures stable and zero-leakage operation, fully adapting to flexible production line changes.
Q: Worried that slight pulsation generated during long-term continuous operation will affect material conveying uniformity and cause printing and coating precision deviations.
A: The HNDP25 low noise pneumatic diaphragm pump is designed with ultra-low pulsation conveying performance, which can fully meet production requirements under standard working conditions. For high-precision production lines, a pulsation damper can be installed to further optimize flow stability, eliminate feeding deviations and ensure consistent production accuracy.
Q: Long-term conveyance of particle-containing sludge, impurity wastewater and corrosive waste liquid may cause sediment accumulation in the pump chamber and pipelines, as well as corrosion and wear of wearing parts, resulting in reduced flow rate, poor conveying efficiency and pump leakage.
A: For media containing solid particles, a filter can be installed at the inlet of the HNDP25 diaphragm pump to block large impurities. Before selecting the pump body and wetted part materials, we will confirm the properties of the conveyed media and recommend suitable material configurations to extend service life. Regular cleaning of the pump chamber and pipelines is required to prevent residue accumulation. Meanwhile, inspect wearing parts periodically and replace worn components in a timely manner to eliminate leakage risks and maintain stable conveying performance.
