1. Introduzione
This manual provides essential information for the safe and efficient operation, installation, and maintenance of your MXBAOHENG Air-Operated Double Diaphragm Pump, Model HQ-2588. This pneumatic pump is designed for transferring various flowing liquids, including those that are difficult to move, across a range of industrial and chemical applications.
Key features of this pump include:
- Prestazioni affidabili: Engineered for long service life with low noise and vibration.
- Sicurezza operativa: Designed to prevent damage from dry running or sudden stops. Features automatic shutdown upon overload and restarts when conditions normalize.
- Design semplificato: Simple structure with minimal wearing parts, facilitating easy installation and maintenance. The conveyed medium does not contact internal moving components.
- Applicazione versatile: Suitable for various industries including textile, chemical, pharmaceutical, spraying, and sewage treatment.
2. Istruzioni di sicurezza
Read all safety instructions carefully before operating the pump. Failure to follow these instructions may result in equipment damage, personal injury, or property damage.
- Compatibilità chimica: This pump utilizes a PTFE diaphragm, which is resistant to many acids and alkalis. However, the pump body is constructed from aluminum alloy. Do not use this pump to transfer strong acids or alkalis that may react with aluminum alloy. Always verify chemical compatibility before use.
- Evitare la corsa a secco: The pump must not be operated without liquid (empty) for extended periods. Running the pump dry can cause internal damage and lead to bursting. Ensure there is always liquid in the system during operation.
- Air Pressure Limits: The optimal operating air pressure for this diaphragm pump is 4 kilograms (approximately 3.9 bar). The maximum permissible air pressure is 6 kilograms (approximately 5.88 bar). Exceeding 6 kilograms of air pressure will damage the pump.
- Compressed Air Source: Use clean, dry compressed air as the power source. This design eliminates sparks, making it suitable for various flammable and explosive environments.
- Ambiente di installazione: Ensure the pump is installed in a well-ventilated area, free from obstructions.

5. Configurazione e installazione
Follow these steps for proper setup and installation of your diaphragm pump:
- Montaggio: Securely mount the pump on a stable, level surface using the provided stand bar and pump stand columns. Ensure adequate space around the pump for maintenance and operation.
- Collegamenti fluidi: Connect the fluid inlet (3/8 inch) to your liquid source and the fluid outlet (3/8 inch) to your destination. Ensure all connections are tight and leak-free.
- Collegamento aereo: Connect a clean, dry compressed air line to the 1/4 inch NPT air inlet. Install an air regulator and pressure gauge to monitor and control the air pressure.
- Installazione del silenziatore: Ensure the noise reduction silencer is properly attached to the air exhaust port.
- Innesco del sistema: Before initial operation, ensure the pump and suction line are filled with the liquid to be transferred to prevent dry running.
6. Funzionamento
Operating the MXBAOHENG diaphragm pump is straightforward:
- Verifica connessioni: Double-check all fluid and air connections for security and absence of leaks.
- Imposta la pressione dell'aria: Gradually increase the air pressure to the optimal operating range of 4 kg (approx. 3.9 bar). Do not exceed the maximum of 6 kg (approx. 5.88 bar).
- Inizia a pompare: The pump will begin operation once compressed air is supplied.
- Regola la portata: The flow rate can be adjusted by varying the air pressure. Higher air pressure generally results in a higher flow rate, up to the maximum of 18 L/min.
- Arresto della pompa: To stop the pump, simply close the air supply valve. The pump will cease operation.
7. Manutenzione
Una manutenzione regolare garantisce la longevità e le prestazioni ottimali della pompa:
- Ispezione di routine: Periodically inspect all connections, hoses, and the pump body for signs of wear, damage, or leaks.
- Controllo del diaframma: Although designed for durability, diaphragms are wearing parts. Inspect them for cracks or fatigue during routine maintenance. Replace if necessary.
- Silencer Cleaning: The detachable silencer can be cleaned to maintain its noise reduction effectiveness. Refer to Figure 4 for a visual of the silencer.
- Qualità dell'aria fornita: Ensure your compressed air supply remains clean and dry to prevent contamination and wear of internal components.
- Magazzinaggio: If storing the pump for an extended period, flush it with a compatible cleaning solution or water, then drain completely to prevent residue buildup or freezing.
8. Risoluzione Dei Problemi
Per i problemi più comuni e le possibili soluzioni, fare riferimento alla seguente tabella:
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Pump does not start or runs intermittently | Insufficient air pressure; Air supply disconnected; Clogged air inlet/valve; Overload condition. | Check air supply and pressure (ensure 4-6 kg); Verify air line connection; Inspect and clean air inlet/valve; Reduce load or clear obstruction. |
| Portata ridotta | Low air pressure; Clogged fluid lines/inlet; Worn diaphragms; Air leak in suction line. | Increase air pressure (within limits); Clear fluid lines; Inspect and replace diaphragms; Check and seal suction line connections. |
| Pump leaking fluid | Loose connections; Damaged diaphragms; Cracked pump housing. | Tighten all fluid connections; Inspect and replace diaphragms; Contact support for housing damage. |
| La pompa fa rumore eccessivo | Loose components; Damaged silencer; Cavitation (if pumping viscous fluids). | Check and tighten all bolts; Inspect and replace silencer; Ensure proper fluid supply and reduce suction lift. |
| Pump bursts or is damaged | Running empty for too long; Exceeding maximum air pressure; Pumping incompatible chemicals. | This indicates severe misuse. Review safety instructions. Replacement of damaged parts or the entire pump may be necessary. |
