Performance and structural characteristics

1.The Good applicability of ship

The structure is simple and reliable

**0WN ~ **0WN dredge pump using a  whole single pump shell, single-stage single-suction structure, according to the connection with the gear box can provide two typical structure, that is, comes with bracket and pump box combined. Bracket-type lubrication comes with grease lubrication or thin oil lubrication.
