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. Pumpa 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. Postavljanje i instalacija
4.1 Raspakivanje i pregled
- Pažljivo izvadite pumpu iz ambalaže.
- Inspect the pump for any visible damage that may have occurred during shipping. Report any damage to your supplier immediately.
- Provjerite da li su prisutne sve komponente navedene na listi za pakovanje.
4.2 Montaža pumpe

4.3 Vodovodne veze
- Connect the suction pipe to the pump's inlet (1 1/4 inch) and the discharge pipe to the outlet (1 inch).
- Use appropriate pipe thread sealant on all connections to prevent leaks.
- Ensure that the piping is adequately supported to prevent strain on the pump connections.
- Ako crpite vodu iz bunara ili rezervoara, na kraju usisne cijevi ugradite nožni ventil sa filterom.
4.4 Električni priključak
- Osigurajte da napajanje odgovara snazi pumpe.tagzahtjevi (230 VAC).
- Connect the pump to a dedicated, properly grounded electrical circuit protected by a circuit breaker or fuse.
- All electrical wiring should be performed by a qualified electrician in accordance with local electrical codes.
5. Operacija
5.1 Punjenje pumpe
Before initial start-up or after the pump has been drained, it must be primed.
- Remove the priming plug (if present) or open a valve on the discharge side.
- Napunite pumpu casing completely with water until it overflows.
- Replace the priming plug or close the valve.
5.2 Pokretanje pumpe
- Ensure the pump is properly primed.
- Open any necessary valves on the suction and discharge lines.
- Uključite napajanje pumpe. Pumpa bi trebala odmah početi s radom.
- Pratite pumpu na neobične zvukove ili vibracije tokom prvih nekoliko minuta rada.
5.3 Isključivanje pumpe
- Isključite napajanje pumpe.
- Close any necessary valves on the suction and discharge lines to prevent backflow.
6. Održavanje
Redovno održavanje osigurava dugotrajnost i optimalne performanse vaše pumpe.
6.1 Routine Checks (Weekly/Monthly)
- Check for any leaks around the pump casing or pipe connections.
- Listen for unusual noises or vibrations during operation.
- Pregledajte oštećeni kabel napajanja.
- Ensure the pump is adequately ventilated and free from debris.
6.2 Čišćenje
- Periodically clean the exterior of the pump to prevent dirt buildup.
- If the pump is used with dirty water, regularly check and clean the strainer on the suction line.
6.3 Priprema za zimu/skladištenje
- If the pump will not be used for an extended period or in freezing temperatures, drain all water from the pump casing and pipes to prevent damage from ice expansion.
- Store the pump in a dry, protected area.
