2. Maklumat Keselamatan
WARNING: Always disconnect power before performing any maintenance or installation procedures.
- Ensure the pump is installed by qualified personnel in accordance with local electrical and safety codes.
- Wear appropriate personal protective equipment (PPE) when handling chemicals and operating the pump.
- Verify that the chemical being pumped is compatible with the pump's wetted materials (PTFE, PVDF, FKM, glass) to prevent corrosion and failure.
- Do not operate the pump dry. Ensure the suction line is always submerged in the chemical solution.
- Protect the pump from extreme temperatures, direct sunlight, and corrosive environments.
- Ensure proper ventilation when operating the pump, especially with volatile chemicals.
3. Produk Lebihview
The Hanna Instruments BL1.5-1 Blackstone pump is engineered for durability and precision. It features a solenoid-driven mechanism that ensures each stroke is identical, providing highly accurate and consistent flow rates. The pump is constructed with high-quality, chemical-resistant materials including Polytetrafluoroethylene (PTFE), Polyvinylidene Fluoride (PVDF), Fluoroelastomer (FKM), and glass components, making it suitable for a wide range of aggressive chemicals.

4. Persediaan dan Pemasangan
4.1 Membongkar
Carefully remove the pump and all accessories from the packaging. Inspect for any signs of damage. Report any damage to your supplier immediately.
4.2 Pemasangan
The Blackstone pump offers flexible mounting options:
- Pemasangan Mendatar: The pump's broad, flat base and pre-drilled mounting holes allow for secure installation on a tank, shelf, or floor.
- Pemasangan Menegak: Mounting holes on the rear of the pump housing facilitate vertical installation on a wall, tank, or machine. Ensure the mounting surface is stable and capable of supporting the pump's weight when filled with fluid.
Ensure that the pump valve assembly and controls on the front of the unit are easily accessible after mounting for installation and flow adjustments.
4.3 Connecting Valves
Each BL pump is supplied with discharge and suction valves. Connect these valves securely to the appropriate ports on the pump. Ensure all connections are tight to prevent leaks, especially when dealing with corrosive chemicals.
- Talian sedutan: Connect the suction valve to the chemical source. Ensure the suction line is free of air bubbles and fully submerged in the chemical solution.
- Talian Pelepasan: Connect the discharge valve to the point of chemical injection.
4.4 Sambungan Kuasa
The pump accepts 115 V, 50/60 Hz power. Connect the pump to a grounded power outlet. Ensure the power supply matches the pump's requirements. Use a dedicated circuit if possible to avoid interference with other equipment.
5. Arahan Operasi
5.1 Initial Start-up and Priming
Before starting, ensure all connections are secure and the suction line is properly submerged. The pump may need to be primed to remove air from the system.
- Turn the flow rate control knob to its maximum setting (100%).
- Apply power to the pump.
- Observe the LED indicator. It will flash with each stroke.
- Allow the pump to run until a steady flow of chemical is observed at the discharge point, indicating that the system is primed and air-free.
- Once primed, adjust the flow rate as needed.
5.2 Melaraskan Kadar Aliran
The Hanna Instruments BL Series Blackstone pumps are equipped with a single control for pump output: an external flow rate control potentiometer located on the front face of the pump.
- Rotate the knob clockwise to increase the flow rate.
- Rotate the knob counter-clockwise to decrease the flow rate.
This knob allows you to adjust the percentage of flow from 0% to 100% of the pump's rated capacity (1.5 LPH). The LED indicator will flash with each stroke, allowing you to visually confirm the pump's operation and stroke rate.
6. Penyelenggaraan
WARNING: Disconnect power before performing any maintenance.
6.1 Pemeriksaan Berkala
- Periodically inspect all tubing and connections for leaks, cracks, or signs of wear. Replace damaged components immediately.
- Check the suction and discharge valves for proper operation and cleanliness. Chemical residue can build up and affect performance.
- Ensure the pump's exterior is clean and free of chemical spills.
6.2 Pembersihan
If chemical residue builds up, clean the pump's exterior with a damp cloth. For internal cleaning or descaling, consult a qualified technician or refer to specific chemical cleaning procedures compatible with the pump's materials.
6.3 Penyimpanan
If the pump is to be stored for an extended period, flush it thoroughly with clean water to remove all chemical residues. Disconnect power and store in a dry, clean environment.
7. Penyelesaian masalah
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| Pump not operating / No LED indicator | No power supply; Faulty power connection; Internal electrical fault. | Check power connection and outlet; Ensure power switch is ON; Contact technical support if power is confirmed. |
| No flow or inconsistent flow | Air in suction line; Clogged suction/discharge valve; Suction line not submerged; Chemical source empty; Flow rate set too low. | Prime the pump (see Section 5.1); Clean valves; Ensure suction line is fully submerged; Refill chemical source; Increase flow rate setting. |
| Kebocoran pada sambungan | Loose fittings; Damaged tubing/valves. | Tighten all connections; Inspect and replace any damaged tubing or valves. |
