Sulzer ZF 100/125

Sulzer Pumps Sulzer ZF 100/125 is identified in the source list as a deepwell cargo pump. It is installed vertically in or through a cargo tank, with the pumping element positioned to remove cargo from the tank and the drive or transmission arranged according to the vessel design. Its purpose is to discharge or circulate liquid cargo while minimizing long suction piping from the tank bottom. The existing record identifies cargo-service duty for this pump. The long vertical arrangement makes shaft alignment, bearings, column sections, sealing and cargo compatibility important to reliable operation. The exact model designation identifies pump size and hydraulic selection within the cargo-pump family; capacity, head, materials and permissible cargoes must be confirmed from manufacturer and vessel documentation.

Common failures & inspection points

●Bearing or line-shaft wear caused by poor lubrication, misalignment or unfavorable operation, resulting in vibration, noise or rising drive load
●Hydraulic wear or impeller damage caused by cavitation, solids or corrosion, resulting in reduced cargo discharge rate and unstable pressure
●Seal or column leakage caused by gasket, seal or joint deterioration, resulting in cargo leakage or loss of containment
●Drive or coupling fault caused by motor, hydraulic drive or mechanical transmission problems, resulting in inability to start or reduced pump speed
●Suction starvation or gas entrainment caused by low tank level, vortexing or blocked inlet, resulting in cavitation noise, vibration and poor delivery

Service & Maintenance

Inspect accessible drive, coupling, top seal, column connections and monitoring points before cargo operations. Trend vibration, drive load, discharge pressure and delivery and investigate deviations from normal performance. Maintain the pump within the cargo compatibility and operating conditions specified for the vessel. Inspect hydraulic components, bearings and shaft sections during scheduled tank entry or overhaul. Check shutdown, remote control and emergency-stop functions before loading or discharge operations. Refer to manufacturer and class documentation for exact wear limits, alignment criteria and cargo restrictions.

Replacement Parts

Keep top-seal and gasket sets, bearings, coupling components, drive-system consumables and manufacturer-recommended impeller or shaft-line wear parts. Spare strategy should reflect cargo-service criticality and the difficulty of removing the pump from the tank. Confirm materials and parts against the exact model and cargo application.
