<p>#CMT# #/CMT# A rotary blade (18) is provided on the suction side of the pump casing (2) in an upstream position relative to the pump fan (20, 21). #CMT# : #/CMT# The pump casing has a bearing side which can be connected to a bearing housing (7) containing the pump shaft on which the fan is mounted. A suction connection is axially mounted inside the pump casing. An outlet (28) is located next to the fan periphery. A drive mechanism (12) is provided for the pump shaft. An independent claim is also included for a vehicle fitted with the dredger so that the suction side of the latter can be placed inside the medium requiring dredging. #CMT#USE : #/CMT# For dredging drainage ditches or canals. #CMT#ADVANTAGE : #/CMT# The blade cuts any large pieces of material entering the pump into smaller pieces, reducing the risk of the pump becoming blocked or dredging capacity becoming reduced. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a cross-section of the dredger. 2 : Pump casing 7 : Bearing housing 12 : Drive shaft 18 : Rotary blade 20 : Fan plate 21 : Fan blade 28 : Outlet.</p> |
