Hydroman submersible slurry pumps can be installed in many different ways. However, there are some general rules regarding installation that should be considered no matter what the application.
1. Dry installation
In a dry installation, the hydraulic end and the drive unit are located outside the Submersible slurry pump.
The submersible slurry pump must always be installed with a cooling system. For the TJQ series, water for the cooling jacket must be supplied externally. The holes for the pressure isolation zone must also be plugged or external seal flushing added.
Consider the design of the sump in order to feed the submersible pump with the slurry. An agitator and side mounted cutter cannot be used in this installation method. Cutters on guide bars in the sump/tank should be considered in order to keep solids in suspension to avoid settlings in the sump/tank.
2. Submerged installation
In a submerged installation, the submersible slurry pump operates directly in the slurry and requires no support structure.
When using a submersible slurry pump the purpose should always be to transport the particles and not just the liquid.
If possible, the sump should be equipped with sloping walls to allow the sediment to slide down to the area directly under the submersible dredge pump inlet. Use an agitator when there is a high solids content and when the density of the particles is high. A stand-alone or a side-mounted mixer is an excellent option to re-suspend the solids, when the sump is large or lacks sloping walls.
The side cutters can also help the agitator when pumping very high density particles.
In applications where the sump volume is small and/or there is a wish to pump down to lower water levels in the sump, a TJQ/TSQ series electric slurry pump with internal cooling system should be considered in order to avoid overheating of the stator.
3. Raft installation
A raft installation is an option to be considered when pumping sediments from dams or lagoons. An agitator is recommended as well as one or more side cutters that can be mounted to the raft to re-suspend particles so that pumping of particles can be achieved.
The side cutters can either be mounted on the submersible sand pump or directly on the raft.
Different applications need different types of installation for your submersible slurry pump. If you have any questions about the best type of installation for your application, contact Sales@tobeepump.com.
