Selection and application
Household sewage pumping stations of the METALCHEM-WARSZAWA type, abbreviated to PDM, are intended for the discharge of domestic and sewage, drainage or rainwater from individual residential buildings, utility buildings or small housing associations. They are mainly used to service farms lying far away from the main sewage network or places preventing the use of gravitational drain. PDM is divided into one and two pump systems built in Ø800mm and Ø1000mm tanks. PDM can also be used as drainage for garages, properties or as temporary pumping stations. Lightweight and compact design, allows quick installation on the construction site and does not require special effort or machinery (cranes, excavators). Two or three people are enough to move depending on the size of the tank.
Due to small inflows of sewage, designers often choose systems with thin pressure pipes, guided by the theoretical parameters of the pumping station operation. This involves the use of pumps with small passages and generating high pressure. The pumping stations designed in this way are characterized by really low efficiency and high operating costs. Pumps with small passages and / or shredding equipment often get clogged. The consequences of this are downtime (failures) of the pumping station, significant costs of servicing pumps and cleaning the pumping station by specialized units. Therefore we reccomended small pumping stations with pipes no smaller than Dn50 inside and outside of the tank.

In the pumping stations we offer, we use internal pipeline diameters not less than Dn50 and the outlet from the PE63 pumping station or larger. We also prefer pumps with 50mm free passage under the impeller. The only justified case of using pumps with a grinder and a small outlet is a pumping station intended only for a single house (family). This is connected with taking responsibility for the garbage thrown into the sewage system. For two or more users, it is usually difficult to determine who is guilty of throwing rubbish into the sewage system, and the costs involved can be significant.
In our pumping stations we use two pump fastening systems: on the hook coupling and on the Dn50 autocoupling elbow. Both systems allow easy removal of the pump in case of failure and flooding of the pumping station. The KS50 coupling elbow and two guides are particularly recommended because even with a completely flooded pumping station, it is very easy to remove and lower the pump (for example during service).
