  • Patent number: 11512715
    Abstract: A device for protection of wastewater pumps for wet accumulation chambers has a separation chamber provided with a discharge pipe for discharging wastewater into a sewerage network. A supply pipe connected to the separation chamber supplies solid particles containing wastewater into the separation chamber. A reversing valve arranged between the supply pipe and the separation chamber prevents reverse flow of wastewater into the supply pipe. A bidirectional pipe connected to the separation chamber connects the separation chamber with a pump, where the bidirectional pipe serves to supply wastewater from the separation chamber into the pump positioned in the wet accumulation chamber and for reverse flow of wastewater from the pump into the separation chamber to a discharge pipe. A solid particles separator arranged between the separation chamber and the bidirectional pipe separates solid particles contained in wastewater in the separation chamber.
