| Description: | This heavy-duty water pump is designed for Volvo Penta industrial and generator diesel engines including TAD and TD series applications. It ensures proper coolant circulation through the engine block, cylinder head, radiator, and heat exchanger system.
Engine overheating in generator and industrial applications can cause catastrophic damage. This pump restores full coolant flow capacity and maintains stable operating temperature under continuous load conditions. Engineered to meet or exceed OEM cooling flow and pressure requirements. Ideal for generator sets, standby power units, marine auxiliary engines, and industrial power systems.

| Important Fitment Note:
|
This pump fits specific Volvo Penta TAD and TD series engines only.
It does NOT fit automotive Volvo passenger vehicles. Always confirm: • Engine model If unsure, send us your engine data plate photo.
|
| Warning: | Do not reuse old coolant contaminated with oil or debris. Flush the cooling system before installation. Replace the thermostat if overheating occurred. Inspect the drive belt and tensioner condition during installation. Improper installation may cause seal failure and coolant leakage.
|
| Quality Assurance Note: | • Pressure tested mechanical seal • Balanced impeller for smooth operation • Precision machined housing • Leak tested before packaging • Designed for continuous-duty generator applications |
| Technical Recommendation: | If pump failed due to overheating:
1. Pressure test radiator and heat exchanger 2. Inspect thermostat operation 3. Check belt alignment and tension 4. Verify coolant mixture 50/50 antifreeze 5. Check for combustion gases in coolant For high-hour generator engines, proactive pump replacement during overhaul reduces downtime risk. |
