Ürünler Sektör Bilgisi

Diaphragm pump is a positive-displacement fluid transfer device that uses flexible diaphragms and check valves to realize suction and discharge through reciprocating movement. As a core equipment for industrial fluid transportation, Diaphragm pump supports stable delivery of corrosive, high-viscosity, particle-containing and shear-sensitive media, with good sealing and dry-running capability. Shanghai Haoyang Pump Valve Manufacturing Co., Ltd. focuses on Diaphragm pump R&D and production since 2006, providing CE-certified, ISO9001-compliant Diaphragm pump solutions for global users.

Working Principle

Diaphragm pump forms alternating volume change via diaphragm reciprocation, generating pressure difference to drive fluid flow.

  • Suction stroke: Diaphragm moves outward, chamber volume increases, inlet valve opens, fluid enters
  • Discharge stroke: Diaphragm moves inward, chamber volume decreases, outlet valve opens, fluid discharges
  • Check valves maintain one-way flow; dual-diaphragm structure ensures continuous output

Shanghai Haoyang HY series air-operated diaphragm pump adopts optimized air valve structure, improving operation stability and service life.

Core Performance & Product Highlights

  • Seal-less & leak-proof: Diaphragm isolates fluid and drive system, suitable for hazardous media
  • Self-priming capability: No need for pre-filling, adapts to low-pressure suction conditions
  • Explosion-proof & safe: Air-driven version avoids electric sparks, usable in hazardous areas
  • Wide media adaptability: Transfers liquids, slurries, viscous fluids and particle-containing media
  • Energy-saving & stable: Low air consumption, steady flow, reduced downtime

All Diaphragm pump products of Shanghai Haoyang hold CE certification and comply with international industrial standards.

Typical Application Cases

  • Chemical industry: Acid, alkali, solvent and pigment delivery
  • Petrochemical: Oil sludge, waste liquid and flammable fluid transfer
  • Food & beverage: Syrup, jam, edible oil and cleaning agent pumping
  • Environmental protection: Wastewater, sludge and flocculant dosing
  • Coating & printing: Paint, ink and adhesive supply
  • Mining & metallurgy: Slurry, ore powder and wastewater treatment

Shanghai Haoyang Diaphragm pump provides long-term stable operation in the above scenarios.

Comparison of Diaphragm Pump with other common fluid transfer pumps

Maintenance Guide

1. Daily inspection

  • Check air pressure, pipeline connection and valve action
  • Observe flow stability and abnormal noise

2. Regular maintenance (recommended by Shanghai Haoyang)

  • Clean filter every 500 working hours
  • Inspect diaphragm and check valves every 1000 hours
  • Replace wearing parts according to media corrosion level

3. Long-term storage

  • Clean pump chamber and dry internal parts
  • Store in dry, ventilated environment

FAQ

1. What is the suitable air pressure range for air-operated diaphragm pump?

Recommended working pressure: 0.2–0.8 MPa. Excessive pressure shortens diaphragm life; insufficient pressure reduces flow. Shanghai Haoyang HY series supports stable operation within this range.

2. How to select diaphragm material?

  • NBR: Oil-based media
  • FKM: Strong corrosive chemicals
  • PTFE: High-corrosion, high-temperature media

Shanghai Haoyang provides material matching for Diaphragm pump.

3. Why does flow rate decrease?

Possible causes: clogged filter, worn diaphragm, damaged check valve, insufficient air pressure. Follow Shanghai Haoyang maintenance manual for troubleshooting.

4. Can diaphragm pump run dry?

Yes. Diaphragm pump allows dry running without damage, suitable for intermittent operation.

5. Do you provide custom Diaphragm pump?

Yes. Shanghai Haoyang supports material, interface, flow and pressure customization for global wholesale clients.
