How can the customer know which pumping station to choose? Is backyard pumping station sufficient for: one house, two, five or a small housing estate? When does it become a network pumping station and how do they differ? What should be in a home pumping station and what characterizes network pumping stations? When to put a pumping station into rainwater and when combined? You can ask a lot of such questions and you can create a lot of new definitions of pumping stations due to their purpose, quantity and type of pumped medium. Below we present the basic division of pumping stations, most often chosen by customers. If you don't find anything among them, please contact our sales or construction department. We will thoroughly analyze your inquiry and try to find the right solution.

Jakie pompy do scieków

Sewage pumping stations (raw) - they are usually pumping stations for domestic and household sewage discharged from washbasins, bathrooms, flats, houses and factories. In addition to dirty water, the pumped medium also contains solids of various sizes, which are thrown into the sewage system by users. They are so-called raw sewage, which requires pumps with large passages, at least 50mm and most often 80mm. Pumps with large passages under the impeller (applies to Vortex impellers) have lower efficiency than the channel pumps, but they are much more resistant to clogging and entanglement of fibrous materials on the impellers, which makes their operation cheaper. Channel sewage pumps can also be used for raw sewage, but in our experience only pumps with one channel. The liquid stream, together with the solids it contains, goes entirely through the inlet to the impeller and then slides along the wall of the pump body to the throat and outlet from the pump. In the case of multi-channel impellers, the stream splits and there is a high probability of hitting two ends, e.g. rags or strings, in separate channels, then the garbage is immediately wound on the impeller and, as a result, the pump clogs. Such cleaning requires pulling out the pump, removing the body, pulling out the wound (often using cutting tools), and then fitting the pump body and fine-tuning the gap between the impeller and the body. In most cases, Vortex impellers can be cleaned without dismantling the pump, and it is easy to remove clogged garbage through the pump inlet.

Rainwater pumping stations - all other pumping stations can be included in this group due to the fact that the pumped medium without solid and fibrous bodies, at most medium, carries with it fine sands. In this group we can fit and pump pre-treated (mechanically) sewage, rainwater, drainage and process water. The differences depend on the type of control, rotor resistance to abrasion in contact with medium or the level of pump activity than for raw sewage.

What is the difference between rainwater and waste water process control?

The Sewage control usually has four levels:

  1. DRY - to protect the pump against dry running and overheating of the engine,

  2. MINIMUM - pump stop level,

  3. MAXIMUM - start level of one pump,

  4. ALARM - critical level, switching on the second pump and signaling to the user,

In addition, sewage control also has simultaneous activation of two pumps every 10 cycles to increase flow and flush the discharge pipeline. It is possible to block the simultaneous operation of two pumps due to power restrictions.

The Rainwater control usually has five levels:

  1. DRY - to protect the pump against dry running and overheating of the engine

  2. MINIMUM - pump stop level

  3. PUMP I - switching on first pump

  4. PUMP II - switching on second pump

  5. ALARM - critical level and signaling to the user
