  • Submersible pressure pumps are known from the prior art, which can suck in a liquid in different ways.
  • the liquid is either sucked in close to the ground in the lower area of the submersible pressure pump through the large suction basket or via an additional hose which is connected to the bottom of the pump and floats near the surface of the liquid using a buoyancy unit, so that the Liquid is sucked in near the surface.

  • conventional submersible pressure pumps do not lie stably on their side on the ground and then roll back and forth.
  • changing between the two suction situations is complex because the submersible pressure pump has to be partially dismantled for floating extraction, i.e. for installing the hose.
  • the inventors have recognized that the change in suction situations or the necessary changes to the submersible pressure pump can be done without tools, without having to at least partially dismantle the submersible pressure pump.
  • a simple adapter is suitable for this, which can be inserted into the submersible pressure pump without tools. so that one or the other suction situation is created depending on the adapter design.
  • an external float switch experiences improved buoyancy if its righting moment is different depending on the area of the float switch.

  • the liquid is preferably water. However, in principle, any other liquid can also be sucked in and pumped with the submersible pressure pump according to the invention.
  • the submersible pressure pump according to the invention has a pump housing. Furthermore, according to the invention, the pump housing has a housing outlet and two housing inlets.
  • the first housing inlet is designed as a suction basket with a large-area suction grille and represents a large-area inlet with a large number of openings such as round holes, slots or the like.
  • the openings of the first housing inlet are formed laterally, but preferably in the lower region of the pump housing.
  • the second housing inlet is designed as a single opening in the bottom of the pump housing.
  • the pump housing can be made in one piece or in several parts. Furthermore, a cover for the pump housing can be provided to protect the pump housing and to improve handling of the submersible pressure pump.
  • the cladding is made in one piece or in several parts. In a particularly favorable embodiment, the cladding is made in several parts includes at least an upper fairing part, a middle fairing part and a lower fairing part.
  • the submersible pressure pump has a liquid pump arranged in the pump housing with a liquid level-dependent or pressure-controlled on/off switch and a suction inlet into the liquid pump, through which the liquid is sucked in through one of the housing inlets and then enters the liquid pump.
  • the liquid pump includes, for example, three or four impellers, which generate the necessary negative pressure to suck in the liquid. Other embodiments of the liquid pump are also possible.
  • the liquid is sucked in either through the first housing inlet or the second housing inlet.
  • a fluidic connection is formed between the suction inlet and the first housing inlet, with the second housing inlet being closed, for example by means of a screw cap or a cap with a bayonet lock or an insertable cap such as a rubber cap or the like.
  • the liquid is then sucked in through the large first housing inlet.
  • a fluidic connection is formed between the suction inlet and the second housing inlet, while at the same time the fluidic connection between the suction inlet and the first housing inlet is interrupted, so that the liquid is sucked in through the individual second housing inlet.
  • an adapter is used to change from the first suction situation to the second suction situation.
  • This adapter is inserted into the second housing inlet instead of the conventional closure, which closes the second housing inlet in the base in the first suction situation.
  • the adapter is preferably provided with an additional sealing ring for sealing the suction thread from the suction opening of the impeller set.
  • the adapter In the second suction situation, the adapter, on the one hand, interrupts the fluidic connection between the suction inlet and the first housing inlet and, on the other hand, establishes the fluidic connection between the suction inlet and the second housing inlet.
  • Changing the suction situation is therefore carried out in a simple manner by replacing the cover in the second housing inlet with the adapter or vice versa. This is advantageously done without tools.
  • Another advantage is that it is not necessary to dismantle parts of the submersible pressure pump, in particular parts of the pump housing, to change the suction situation.
  • the adapter is designed as a cover, which can be inserted into the second individual housing inlet.
  • the adapter is designed as a screw cap or as a cap with a bayonet lock or as a plug-in cap such as a rubber cap or the like.
  • the cover can advantageously be inserted and removed into the second housing inlet without tools.
  • the adapter preferably includes a threaded connector so that the liquid can be sucked in through the adapter.
  • the threaded connector is advantageously formed centrally in the lid so that it has an opening.
  • the adapter designed as a cover closes the second housing inlet and at the same time creates the fluidic connection to the suction inlet via the threaded connector, so that the liquid can be sucked through the threaded connector through the cover.
  • the threaded connector is inserted with the cover into the second housing inlet and is advantageously placed on the suction inlet in such a way that the suction inlet is connected exclusively to the second housing inlet or the opening of the adapter cover through the threaded connector. That means with others In other words, the liquid can only be sucked in through the threaded connector in the second housing inlet.
  • Other embodiments than the threaded connector for producing a suction-tight connection option for connecting a suction hose or a plug-in connection for the suction hose are also within the scope of the invention.
  • This suction situation is also referred to below as floating removal or suction. Floating removal is particularly suitable for contaminated liquids, where the impurities usually collect in the deeper areas.
  • the hose can preferably be attached to the threaded connector of the adapter without tools.
  • An advantageous embodiment of the submersible pressure pump provides at least one handle on the pump housing, which forms at least one lateral support surface.
  • two handles are formed opposite each other on the pump housing, so that two opposite lateral support surfaces are formed.
  • the handles are preferably integrated into the cladding of the pump housing, in particular into the upper cladding part. If the submersible pressure pump is operated in the floating suction situation, the submersible pressure pump is preferably placed on its side and not standing on the ground, as access to the second housing inlet on the bottom of the pump housing for connecting the hose is easier when the submersible pressure pump is lying down. The submersible pressure pump then lies stably on one side with the hose connected on a support surface formed by a handle. By making the handles or the support surfaces as flat as possible, this prevents the submersible pressure pump from rolling back and forth and possibly causing the hose to become tangled.
  • the on/off circuit of the liquid pump comprises a float switch, the float switch detecting a liquid level that is sufficient for the operation of the submersible pressure pump based on its buoyancy in the liquid. Furthermore, a means for manually overriding the liquid level-dependent on/off switch is advantageously provided.
  • the float switch is designed as an external float switch, which is connected to the pump housing by means of a connecting cable.
  • the external float switch has a central body which is shaped approximately as a three-sided prism, with the connecting cable being connected to the body at a triangular edge.
  • the base surfaces of the three-sided prism are preferably designed as isosceles triangles. The distance between the base surfaces of the three-sided prism starting from the connection of the connecting cable increases, so that the buoyancy of the body of the float switch increases with increasing distance from the connection of the connecting cable.
  • the float switch therefore has a substantially triangular shape both in plan view and in cross section along a plane through the connecting cable.
  • the triangular edge of the float switch to which the connecting cable is attached is hereinafter referred to as the front; the opposite side as the back.
  • the buoyancy of the float switch is improved.
  • the buoyancy or the righting moment of the float switch is due to the triangular basic shape and the Widening of the float switch to the rear in the rear area of the float switch is larger than at the front. This means that the float switch sets itself up even at low liquid levels.
  • a ring is formed around the central body of the float switch, which ensures better gliding of the float switch over a surface and improved buoyancy. Thanks to this design, the float switch is less likely to get caught on uneven surfaces or in a pump shaft.
  • the float switch can either be integrated into the submersible pressure pump or designed externally.
  • the float switch is advantageously integrated into the submersible pressure pump.
  • the override of the liquid level-dependent on/off switch can advantageously be activated.
  • the invention further relates to the use of a submersible pressure pump according to the invention, described above, in a first suction situation, wherein the liquid is sucked in through the large-area first housing inlet and the submersible pressure pump is operated standing in the liquid.
  • the submersible pressure pump is used in a cistern or a water storage tank.
  • the invention still further relates to the use of a submersible pressure pump according to the invention, described above, in a second suction situation, wherein the liquid is sucked in through the individual second housing inlet in the bottom of the pump housing and the submersible pressure pump is operated lying on a surface.
  • the adapter described above is inserted into the second housing inlet.
  • a hose with a is advantageous Buoyancy unit is connected to the adapter and the submersible pressure pump is either in the liquid, for example in a cistern, or the submersible pressure pump is on solid ground in the dry and only the hose hangs in the liquid.
  • the submersible pressure pump can also be suspended and operated, for example, hanging on a rope.
  • the handles are ideal for attaching a rope.
  • the change between the different uses of the submersible pressure pump with the different suction situations is done by the different closure of the second housing inlet.
