Figure 2: Internal Diagram of the Centrifugal Pump. This diagram illustrates the key internal components of the pump, showing the flow path and mechanical parts.

• 1. Pam Casing: The outer housing of the pump, typically made of cast iron, which contains the impeller and directs the fluid flow.
• 2. Discharge Port: The outlet through which the pumped fluid exits the pump.
• 3. Impeller: The rotating component with vanes that imparts kinetic energy to the fluid, increasing its velocity and pressure.
• 4. Motor Shaft: The rotating shaft that connects the motor to the impeller, transmitting power.
• 5. Mechanical Seal: Prevents fluid leakage along the motor shaft where it enters the pump casing.
• 6. Bearings: Support the rotating shaft, reducing friction and ensuring smooth operation.
• 7. Motor Stator: The stationary part of the electric motor that contains the windings, generating the magnetic field.
• 8. Motor Rotor: The rotating part of the electric motor, connected to the shaft, which interacts with the stator's magnetic field to produce torque.

4. Persediaan dan Pemasangan

4.1 Membongkar dan Pemeriksaan

1. Tanggalkan pam dari pembungkusannya dengan berhati-hati.
2. Inspect the pump for any visible damage that may have occurred during shipping. Report any damage to your supplier immediately.

3. Ensure that the piping is adequately supported to prevent strain on the pump connections.
4. Install a foot valve with a strainer at the end of the suction pipe if drawing water from a well or tank.

4.4 Sambungan Elektrik

1. Pastikan bekalan kuasa sepadan dengan voltan pamtage requirements (230 VAC).
2. Connect the pump to a dedicated, properly grounded electrical circuit protected by a circuit breaker or fuse.
3. All electrical wiring should be performed by a qualified electrician in accordance with local electrical codes.

5. Operasi

5.1 Penyebuan Pam

Before initial start-up or after the pump has been drained, it must be primed.

1. Remove the priming plug (if present) or open a valve on the discharge side.
2. Isi pam casing completely with water until it overflows.
3. Replace the priming plug or close the valve.

5.2 Memulakan Pam

1. Ensure the pump is properly primed.
2. Open any necessary valves on the suction and discharge lines.
3. Turn on the power supply to the pump. The pump should start immediately.
4. Monitor the pump for unusual noises or vibrations during the first few minutes of operation.

5.3 Mematikan Pam

1. Matikan bekalan kuasa ke pam.
2. Close any necessary valves on the suction and discharge lines to prevent backflow.

6. Penyelenggaraan

Penyelenggaraan yang kerap memastikan jangka hayat dan prestasi optimum pam anda.

6.1 Routine Checks (Weekly/Monthly)
