Usage:
Wastewater from houses in higher positions flow into the sewerage system due to gravity. Wastewater from houses in lower positions need to be pumped. Domestic pumping station of the company Regeneracija, consists of a shaft, submersible centrifugal pump, level switches, irretrievable valve, shut-off valve, inlet connection for pressure pipe and lid.
Characteristics:
- Product of Bosnia and Herzegovina,
- long lifetime,
- not sensitive to low and high temperature,
- high static load,
- long-term stability and low wear,
- excellent chemical resistance,
- wide product range,
- lesser weight for easier installation,
- easy maintenance.
Functioning:
Waste water from households are pouring into into a manhole. When wastewater in the manhole reaches a certain amount, centrifugal pump pumpes it into the sewage system. In addition to level switch for turning on the pump, another level switch can be adjusted to warn if wastewater level is too high. Special pump rotor prevents the clogging of the pump and pressure pipeline.
In case of failure it is necessary to close the irretrievable valve on the pressure pipe and to extract the pump. Installing and removing the pump is very simple and fast. In case of very short pressure pipe, irretrievable valve and block valve are not required.
Installation:
Domestic pumping station can be installed on transit and non-trafficked surfaces up to the axle load of 125 KN. The manhole is set into the construction pit with a sand foundation. At the inlet height a hole is made and the prefabricated pipe connection is attached.
After that sewer, and pressure pipe under pressure are connected with the manhole. Backfilling of the manhole is described in the section “Instructions for transport and assembly.”
