Submersible pump
Is referred to as a submersible pump, a portable or stationary built-in ( centrifugal ) pump which is immersed in the fluids to be pumped. It is usually powered by electricity, all live parts are insulated from the environment. However, there are also versions which operate by means of hydraulic, because then the pump assembly is easier, because the motor is removed, in this case, however, a corresponding hydraulic pump is necessary. The specific power output moves from about 100 l / min to 2200 l / min. Submersible pumps can be equipped with a float switch. This is for dry run protection or for level regulation.
Submersible pumps in civil protection
The tasks of civil protection, in particular the Technical Relief, demand in the removal of water damage situations with participation in small and medium stakes submersible pumps with high flow and suction. Here, according to STAN equipping the forces with submersible pumps with performance characteristics of 400 l / min and 800 l / min is provided. These are assigned to each group according to salvage STAN and stowed in the vehicles. In addition, the section will water damage / pump THW equipped with submersible pumps with other levels of performance of up to 2,200 l / min. The requirements of the THW in this case relate to a high performance throughput and the possibility of dry suction, continuous operation and the lowest possible residual water level ( level pumping ).
Civil protection uses the comparatively small submersible pumps (see HCP Modules) for execution of operations in residential and commercial installations, here in particular for pumping out flooded basements, sewage and wastewater with high solids content. This case, the portable submersible pumps of the Section for water damage / pump handle solids with a size of up to 80 mm, without causing any damage to the mechanics of the pump.
Submersible pumps for firefighting
In the fire service submersible pumps are used in the framework of technical assistance. In high water use submersible pumps and submersible turbine pumps are typically used. You have the classic water pump largely replaced.
Submersible pumps ( TP) are electrically operated. Depending on the capacity differentiates the types TP 4/1, TP 8/1 or TP 15/1 with a flow rate of 400, 800 or 1500 liters of water per minute at 1 bar pressure. As Departures B- or C- Storz couplings are used.
Turbine submersible pumps (TTP ), however, are driven by the motive water, which is pumped with pressure from a fire pump in the turbine submersible pump and the turbine wheel drives. Turbine submersible pump - - as opposed to a water jet pump as it has separate branches for fuel and dirty water, operation in the circuit fire fighting pump fire fighting pump is possible. The dirty water is discharged through another outlet.
Basically, these submersible pumps, however, are not suitable for extinguishing water supply. Here fire pumps and pool pump systems as the " Hytrans Fire System " will be used.
Submersible pumps in water supply
In the water supply submersible pumps come in smaller wells and cisterns used. A special submersible pump is the submersible motor pump, the handle in the multistage design, larger amounts of water and heads and can be installed even in narrow well pipes due to their design.
Submersible pumps in sewage
In the area of sanitation find submersible pumps in pumping stations application. Here it is particularly reliability. The coarser the admixtures, the greater must be the free passage of the pump to rule out blockages largely can.
Since pumps with large free passages ( in the wastewater sector quite 80 mm ball gear and more ) also always require a corresponding pressure pipeline, there is the opportunity to work with Schneidradpumpen that shred the waste water and for the disposal of wastewater from residential buildings or other individual objects according to encourage under-dimensioned pressure lines (from DN 32 with pressurized drainage ).
Flat suction cups
Flat suction cups are also submersible pumps. Through your flat suction basket, they have the advantage of being able to suck very low standing water. Flat suction cup can be used up to a water level of 1 millimeter
Submersible pumps in the aquarium
Various types of filters in the aquarium hobby use submersible pumps to promote the aquarium water through the filter substrate or back into the aquarium. This is true for most internal filters. Internal filter Industrially manufactured often have an integrated centrifugal pump. The most Build Your Own prepared Hamburg mat filter is usually operated with appropriately sized, to be purchased separately submersible pumps, which can be very small from the outside dimensions. Thus, measures about the model in the picture about 4 x 4 x 3 cm and can accommodate up to 240 l / h promote. The rotor sits on such pumps on a magnetic axis and rotates quasi swimming in water, very low friction and quiet.
