Häufige Probleme

• Gear and bushing wear increasing internal slip, reducing delivered flow and pressure
• Shaft seal leakage at the drive end
• Coupling or belt misalignment causing vibration and noise
• Relief valve sticking or drifting from its set pressure, causing bypass or overpressure
• Cavitation and noisy running from a clogged suction strainer or restricted suction line

Prüfliste

• Check discharge flow and pressure against the rated nameplate values
• Inspect the shaft seal for leakage
• Check relief valve setting and confirm it lifts and reseats correctly
• Inspect coupling/motor alignment and guard condition
• Check the suction strainer for fouling or damage
• Listen for abnormal gear or bearing noise during running

Wartungsintervalle

Kritische Ersatzteile

• Shaft seal kit
• Gear set / bushings
• Coupling element
• Relief valve
• Discharge pressure gauge

Sicherheit

• Rotating coupling and drive must be properly guarded
• Relief valve discharge must be routed so that any bypass cannot strike personnel
• If handling flammable liquids, confirm bonding/grounding arrangements are intact

Klassenbesichtigung

A general service pump of this size is not normally a distinct class survey item unless nominated as part of an essential auxiliary system; it is typically covered by the ship's planned maintenance system rather than a witnessed class test.

Geschätzte Lebensdauer: Small rotary gear pumps of this type typically achieve in the order of 15,000-25,000 running hours before bushing/gear renewal is needed, dependent on duty and fluid handled
