Pump · Pumps
Regular maintenance is crucial for ensuring the reliable operation of marine equipment like the Framo TK80. This portable hydraulically driven submerged pump is designed to handle marine-rated cargo oil, chemicals, and water. Its hydraulic drive and portable installation make it ideal for both regular and emergency use aboard vessels. However, common issues such as hydraulic hose leakage, quick coupling damage, and mechanical seal leakage can occur, necessitating regular inspections and timely replacements of spare parts like the hydraulic hose set, seal kit, O-rings, quick couplings, bearings, and impeller fasteners. According to the service notes, the pump should undergo an operational test as part of the vessel’s preventive maintenance schedule and be flushed after cargo use to prevent impeller blockage by tank debris. Additionally, inspecting the hydraulic hoses, quick couplings, and seal leakage after each use helps to maintain the pump’s optimal performance and longevity.

What our service work and the manufacturer documentation say about keeping this model running.
Operational test according to vessel PMS. Flush after cargo use. Inspect hydraulic hoses, quick couplings and seal leakage after each use.
| Bearing bush inspection | per the manufacturer's interval or after significant running hours in abrasive/dirty service, commonly checked at each major deployment cycle |
|---|---|
| Hydraulic hose inspection and pressure test | before each use visually, full pressure test typically annually |
| Seal inspection | at overhaul or on any sign of product ingress |
| Full strip and inspect | per the manufacturer's interval, commonly annually for frequent users |
Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.
| Bearing bush radial clearance | wear limits vary by pump size and duty - follow the pump's own manual rather than a generic figure; excessive clearance shows up as increased vibration/noise and reduced flow |
|---|
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Where used as part of the vessel's cargo, stripping, or emergency pumping arrangements, class will expect the pump to be included in the relevant system's planned maintenance and, on tankers, in the cargo system's periodic testing records.
Estimated lifetime: Portable submerged cargo/stripping pumps of this type are typically rebuilt on a running-hour or calendar basis (commonly reviewed annually for frequent users) rather than run to a fixed lifetime figure - confirm the manufacturer's recommended overhaul interval for this size.
Keep hydraulic hose set, seal kit, O-rings, quick couplings, bearings and impeller fasteners.
