high pressure gold dredge pump factory

If pump size and type are not defined, it is worth considering the following factors when selecting a dredge pump and dredge pump: type and thickness of material to be pumped, whether diesel or electric power is required, HP (kw) of engine required, pump performance data, durability, ease of maintenance and average life expectancy under normal operating conditions. life, all important attributes in the selection process. Equally important is matching the proper pipe size and composition to maintain proper material flow without clogging the pipe and to maintain the pumping output needed to get the job done.

Fewer and thicker vanes on the impeller. This makes it easier for solids to pass through than the 5-9 vanes on a standard centrifugal pump - typically 2-5 vanes.

The design of the slurry pump is critical to ensure that the abrasive and often corrosive aspects of the slurry do not damage the impeller. In addition, slurries and sludges may contain large amounts of unforeseen solids, which will inevitably clog many types of pumps. Since most centrifugal pump impellers have very tight tolerances on the worm gear, the abrasive (and sometimes corrosive) nature of the slurry will quickly wear down the worm gear and destroy the tolerances. In turn, this causes the pump to lose suction. This can lead to extensive downtime of the slurry pump, as well as expensive maintenance and spare parts.

Mixers can also help agitators when pumping very dense particles. In applications where the tank is small and/or where pumping is desired to lower the water level in the tank, a slurry pump with an internal cooling system should be considered to avoid overheating of the stator (when the water level gets low). When pumping sediment from a dam or lagoon, consider the use of a raft unit, which is a submersible device. Agitators are recommended, as well as one or more mixers that can be mounted on the raft or pump to resuspend particles for successful pumping of particles.

Fewer and thicker vanes on the impeller. This makes it easier for solids to pass through than the 5-9 vanes on a standard centrifugal pump - usually 2-5 vanes.

Positive displacement slurry pumps with limited capacity to deliver high head are used to pump slurry through pipes with very high solids concentrations.
