The TT pump

• The TT Unit in use
• Optionals

In 2005 IHC Holland Parts & Services began the development of a new pump series: the IHC TT-unit. The letters TT are short for Tom Thumb, since it is the smallest pump series produced by IHC. The IHC TT dredging units are a complete range of compact and cost effective dredging units that have been developed to be used for a wide range of smaller scale dredging projects.

The illustration (picture 1) shows the general layout of the TT-Unit. Transport of mixture with the TT-Units is carried out hydraulically by means of a dredge pump. The unit has been furnished with a robust pump with a highly wearresistant pump casing with a wide working range, a large sphere passage and good suction properties. This will allow the unit to operate over a broad range of dredging projects. The graph shows the performance of the TT-Units. The output of solids volume per hour is shown against the discharge length per TT-Unit. Depending on the required output this graph can help in choosing
the right TT-Unit for the job at hand.
