Main components of a pump

Hydraulic part

  • Pump body/casing
    • Volute or diffuser
  • Impellers (open, semi-open, closed, single or multi-stage)
  • Suction/inlet port (flange or threaded connection) and discharge/outlet port
  • Wear rings (between the casing and impeller, reduce internal leakage)
  • Integrated valves (e.g., check valve)

Rotating and supporting part

  • Shaft (transmits torque from the motor to the impeller)
  • Shaft sleeves (protection against wear and corrosion)
  • Bearings (radial and thrust bearing)
  • Mechanical seal or stuffing box (gland) – prevents fluid leakage
  • Seal chamber / stuffing box – seal housing
  • Coupling (in non-submersible pumps)
  • Coupling protection cover (safety)
  • Balancing devices (drum, disc, or holes) (balance in multi-stage pumps)

Electrical system (motor/drive)

  • Rotor (rotating part of the electric motor)
  • Stator (fixed part with electrical windings)
  • Capacitors (in single-phase versions)
  • Power cable
  • Connectors / Cable entry (sealed, waterproof cable entry in submersible pumps)

Structure and accessories

  • Motor / drive (electric motor, diesel motor, turbine)
  • Base / pump frame
  • Pump cover / bearing support
  • Cooling and lubrication system (oil bath, grease, water cooling jackets)
  • Measuring instruments (connections for pressure gauges, sensors, pressure switches, temperature or level probes
  • Filter or suction basket (especially in submersible pumps or for dirty water)
