TK80
Framo TK80 portable hydraulic submerged pump for emergency, stripping and tank transfer duties.
Inspector Detail
▸
Common issues
- Bearing bush wear from running without adequate flushing/lubrication by the pumped medium
- Hydraulic hose or quick-connect coupling leakage
- Shaft seal wear allowing product ingress into the hydraulic drive
- Reduced flow from impeller wear or clogging with debris/sludge
- Hydraulic motor overheating if hose sizing or routing restricts flow
- Corrosion of the submerged housing after tank cleaning chemical exposure
Inspection checklist
- Check hydraulic hoses, couplings, and quick-connects for leaks or damage before deployment
- Function test on deck or in a test tank before lowering into a cargo or void space
- Check bearing bush condition/clearance at scheduled intervals
- Inspect the shaft seal for product ingress into the hydraulic drive
- Verify hydraulic oil supply pressure/flow matches the pump's rated requirement
- Check the impeller for damage or fouling
- Inspect the lifting/lowering wire or guide arrangement
- Confirm correct earthing/bonding before use in flammable cargo service
Service intervals
| 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 wear limits
| 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.
Critical spares
- Bearing bush set
- Shaft seal kit
- Impeller
- Hydraulic hose set with correct couplings
- O-ring/gasket kit
Safety
- Intended for use in flammable/hazardous cargo tanks - confirm gas-free status and use only where the pump's certification permits
- Hydraulic hoses are under pressure - never disconnect under load
- Static/bonding requirements must be observed in flammable atmospheres
- Confirm safe lowering/retrieval procedure and enclosed space entry precautions for the space being pumped out
Class survey
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.
