UNIVERS-T TPO Submersible sewage pump with solid cutting impeller

The UNIVERS-T is especially suitable for pumping uncleaned sewage and waste water. Due to their high level of operational safety, these pumps enable uninterrupted operation of sewage transport systems, for example in specific application areas like the fishing industry, vegetable washing facilities, swimming pools, pumping stations and sewage treatment plants, even in potentially explosive zones.

Impellers

The optimum choice of impeller for the respective pumped medium is guaranteed by the diverse selection of impellers. These ensure the highest degree of operational safety with their efficiency-optimised hydraulics. All multi vane impellers can reach every duty point within the pump’s set of performance curves by correcting the diameter.

General data:

• Pump colour RAL 5010 (standard)
• Media temperature range from 0 to + 40 °C
• Performance verification in conformity with DIN EN ISO 9906, Class 2.
• Max. density of the pumped medium 1050 kg/m³ Max. viscosity of the pumped medium 1.75 mm²/s

Non-clogging system

The non-clogging-system for open single and twin vane impeller ensures the greatest possible operational safety. It is guaranteed by a combination of a hard, unprocessed surface of the wear plate and a specially processed cutting edge on the impeller.

Impellers

Varied impeller designs permit an adaptation to the pum-ped medium and duty point.

Shaft sealing

Single or double-acting mechanical seal with state-of-the-art highly wear-proof materials. The required cooling of the sliding surfaces is generated in a targeted manner through the medium via a by-pass channel. The intermediate casing is filled with lubricating oil to lubri-cate and cool the mechanical seals. This oil even enables a short-term dry run.

By-pass channel

For optimal flushing of mechanical seal by means of the pumped medium. In this way, an efficiency increase is achieved in comparison to a ring chamber rinsing process and the life cycle costs are influenced positively.

Operational safety

Depending on the size of the pump, the highest possible operational safety is achieved by crushing long-fibre ma-terials at the cutting ring of the rear impeller.

Oil chamber

Optimised oil chamber for lubrication and cooling of the mechanical seals. Protection against short-term dry running during suction operation and in case of gaseous media. The intermediate casing can be optionally moni-tored for leaks using a sealing electrode.

Construction

Thanks to uniform dimensions across the entire UNIVERS construction series, different impeller versions can be used in changed working conditions. This means the operator can enjoy enormous flexibility. The pump casings can optionally be fitted with cleaning openings.
