FAQ 

QA：What's the difference between injection pumps and regular fuel pumps?               

       Injection pump: High-pressure (1000Bar+), diesel-only, controls power output.

       Fuel pump: Low-pressure (3-5Bar), just delivers fuel to the engine.

QB： Must I replace a leaking water pump immediately？     

      Minor leak: Temporary sealant works (but reduces lifespan).

      Spraying leak: Stop engine NOW! Risk of overheating damage.

QC： How to troubleshoot a diesel pump that won't prime?                

      Verify fuel level (seriously, some forget to refuel!)

     1.  Check for air in lines (bleed at filter)

     2.Test inlet pressure (should be ≥0.3Bar)

QD： Key parameters when selecting a water pump?        

     Flow rate: e.g. 100L/min (too small causes overheating)

     Head: e.g. 15m (insufficient = poor coolant circulation)

     Shaft material: Stainless steel lasts 3x longer than cast iron

QE：Can high-pressure pumps use regular diesel?       

     Short-term: Yes, but reduces lifespan by 30%+.

     Long-term: Must use EN590 low-sulfur diesel.
