Wastewater and drainage pumps as well as controls and automation technology are topics of the second report that the editors have exclusively put together for readers – live at the Mostra Convegno Expocomfort from 28.2. to 4.3.

Wastewater and Drainage Pumps

Just like in water supply, the drainage and sewage sectors mainly presented optimised versions of proven designs. Especially in the waste water area it seems that stainless steel constructions more and more replace the classic cast iron and synthetic products.

For waste water pumps from the SKIPPER, RIVER and TENAX series Arven now also offers automatically coupled guide rail systems with nominal widths DN50 and DN80 for permanent installation. The pumps are available as single or three phase version and with single channel or vortex impeller or with cutter.

Comex Supersand The SUPERSAND is a contractor pump introduced by Comex. Due to its double outer casing it is also suitable for uses at low water levels. The stainless steel construction is resistant against abrasive particles in pumped media and promises a long life cycle.

The submersible grinder pumps TR from Conforto can, for example, be used for lifting domestic or industrial waste or in slaughter houses. The pumps have a vortex impeller for free passage up to 7 mm. The pumps can be used for liquids with temperatures up to 60°C in continuous operation or up to 90°C in intermittent operation respectively.

The waste water pump FEKA by DAB features easy and rapid maintenance. The modern design offers a double mechanical seal with oil chamber and metallic bearings for long life. Stainless steel as well as special synthetics are available. DAB FEKA (photo: DAB) For easy selection of the right pump DAB now introduces its new pump selection program DNA. The multilingual system is based on the proven Spaix technology by VSX – VOGEL SOFTWARE.

Ebara presents the further development of its submersible drainage pumps Optima, Best One and Best One Vox. The reliable and resistant stainless steel design is offered with 10 m³/h while the max. head is 10 m. A low suction version to suck up liquids up to 3 mm at ground level is optional.

Unilift (photo: Grundfos) The UNILIFT CC by Grundfos pumps domestic waste and grey water as well as leakage water from the basement sump with a free passage of 10 mm. The pump completely made of corrosion resistant materials can also be used for low suction down to 3 mm due to the removable strainer. A cooling jacket ensures even longer operations in an unsubmerged position.

The drainage pump H-DIG by Rovatti can be used for applications in construction, mining or fire fighting. The design allows for pumping abrasive media. Because of internal circulation of the pumped liquid the transportable pump can operate partially unsubmerged.

The new lifting station SANITSON Premium Salmson is available as single or double pump system. It was re-designed according to European norms. The pumps is mainly used for applications in single or multifamily residences.

Zenit blue (photo: Zenit) The blue series by Zenit was created by the famous designer pininfarina. The drainage and sewage pumps are available either with a multi-vane or vortex recessed impeller. It has a double silicon carbide and a graphite alumina mechanical seal in oil bath.

For lifting household waste water even from lavatories if the level of the sewerage prevents gravity-driven drainage, the blueBOX is the best choice. The lifting station is available for 250 litres content with one pump and a 400 litre model with two pumps. They are designed for use with vortex pumps like the DG model and shredders as the GR model.

Controls and Automation Technology

Interfaces and consequently the connectivity of systems are the essential part of new developments and optimisations in controls and automation technologies. This facilitates an integration into a more complex automation of buildings on the one hand and remote maintenance on the other. The integration of GSM functions enables the transmission of alarm or status messages via mobile communication.

Automation technology was the focus of the German pump and valve manufacturer’s exhibition KSB. Its most representative development was the diagnostic system “PumpExpert”. It delivers clear status reports of pumps, systems and processes and prevents expensive stand stills and consequential costs.

Pentair CPS (photo Pentair) The CPS frequency converter by Pentair (Nocchi) provides constant pressure even at changing water demand through adjusting the motor speed. The module intended for direct mounting at the pump drive can be used for pressurisation, irrigation or in fountains.

The Da Vinci control system by WaCS coordinates up to four pumps equipped with a frequency converter. It was designed for the use in pressure boosting systems. The control has various interfaces to communicate with the rest of the world via GSM, Ethernet or modem.

Commander (photo: Zenit) Zenit introduced its pumping station control units Commander20 and Commander50 for stations of up to two or fife pumps respectively. Depending on the pumped liquid there are three different level switches available. It is possible to have remote control through various interfaces. Malfunctions and upcoming maintenance are signalled by the corresponding alarm function. All alarm functions can also be sent via the optional GSM modem using mobile communication.
