However, if you are planning to pump sand for 8 hours a day for months, then you need to consider one of our larger dredges. If the dredge is used for intermittent cleaning of limited areas such as boat docks, waterfront, canals and channels then one can expect a long time before the pump components wear out. The key wear components in the dredge pump are made of highly abrasion resistant materials, are designed to withstand sand abrasion, and are relatively easy to replace with new parts. Sand is by far more abrasive than mud, and so will wear your pump much more quickly. That will depend upon the type of sediment being pumped, and how often the dredge is used. How long will the mini-dredge pumps last? We prefer to utilise a more conservative value of 2.5 meters per second. The rule-of-thumb minimum velocity for mud and sand is 1.5 to 2.0 meters per second.The term for this is “minimum critical carrying velocity”.
It is important to remember that in order to transport a slurry through a pipe or hose, it must maintain a minimum velocity to prevent the sediment from settling in the hose, eventually forming a restriction or plug. It is important to maintain a minimum discharge velocity (MDV). Our smallest mini-dredgers has a pump with a 25 m head so along our slurry pipes it can comfortably pump 100-150 m over fairly flat terrain. This depends upon the vertical elevation differential, and the type of sediment. How far can the Mini dredge transfer sediment?

Highly portable – can be moved to site on a standard trailer.Pump can handle up to 27mm solids Application of the Mini Dredgers The Mini dredge is a compact, highly portable, petrol-engine powered silt and sediment removal pumping system, designed to provide the homeowner and contractors alike with the ability to excavate and transfer unwanted silt and sediment.For filling of sand geotextile bags and tubes Products and Spares.We know ‘Silt Happens’ but RentADredge can allow you tackle it yourself. Mini Dredgers are the perfect tool for restoring the capacity of the storage capacity of lakes, ponds, and canals. Silt-laden run-off and mud can choke waterfront areas and pontoons/docks. Our mini-dredgers are particularly effective in removing sand, silt, and black stinky mud that accumulates around boat moorings, pontoons, river docks and waterfront areas. Our fleet of mini- dredgers is ideal for hard to access dredging areas where larger equipment cannot operate due to limited access or shallow water.
