The submersible pump industry is full with half-true of even wrong information.

1. Electric sand pump is suitable for dredging.
   (Read on Are You Using The Correct Pump?)
2. Hydraulic dredging pump capacity is material capacity.
   (Read on What Is Your Pump Capacity?)
3. Same capacity of hydraulic dredging pump will have same capacity of material production.
   (Read on Expecting Higher Capacity Of Material Production?)
4. Hydraulic dredging pump or electric sand pump can operate out of water.
   (Read on Is Your Pump On Working Pump Capacity?)
5. Hydraulic dredging pump or electric sand pump can operate at zero head.
   (Read on Is Your Pump On Working Pump Capacity?)
6. With same horsepower, hydraulic dredging pump and electric sand pump will need same dimension and weight of hydraulic power pack and pontoon.
   (Read on Factor That Affects The Dimension Of The Pontoon?)
7. “This pump can pump 60% material by capacity.”
   (Read more on Expecting Higher Capacity Of Material Production?)
8. Electric sand pump able to pump more than 20% material by weight.
   (Read more on Expecting Higher Capacity Of Material Production?)
9. All submersible pumps are suitable for high depth reservoir and deep sea dredging or mining.

10. Installing a water jet ring to a pump will always increase material production.
11. To get top material production, you must run your hydraulic dredging pump at top speed.
12. Diesel engine horsepower is weaker than electric motor horsepower.
