The AWALIFT 1/2 is used primarily in municipal applications for draining large properties. It is a fully automated, floodable sewage pumping system with a proven separator system for up to 750 EW. Alternating two pumps provides a high level of operational reliability. There is no need to provide reserve pumps. This system also has a gas and odor-tight tank, the surface of which is coated with high-quality corrosion protection. •Larger buildings, industrial companies, individual streets •Facilities that cannot be drained using natural gradient •As protection from backwater damage •Infrastructure facilities such as airports, industrial parks, subway systems etc. Product features One tank with two separator systems Two rotary pumps and motors according to type and operating location required Two non-return valves AWASTOP DN 100 K Y-pipe DN 100 Two pressure pipe gate valves DN 100 Level measurement LGA certified according to DIN EN 12050-1 /. -4

Positive displacement blowers and single-stage screw compressors start up directly or following a star delta circuit if no gentle start or no frequency converter control are available. The unit is subjected to heavy mechanical load and requires high start-up current. For this reason, counterpressure must be reduced during the start-up phase; this is achieved by blowing off the increasing volume flow. The fully automatic medium-controlled STRATE relief valve EVA has been specially designed for this procedure. As well as not requiring any maintenance, the STRATE relief valve EVA is an extremely economical device for reducing load during start-up since there is no longer any need to use complex externally controlled valves or electronic start-up aids. Product features Fully automatic control Specialized material G-AISi9Cu3 - specific to the requirements With solenoid valve for different motor speeds With overpressure valve For higher pressures and temperatures

The special lightweight aluminium design and silicone inserts of STRATE sandwich non-return valves SB makes them ideal for: Conveying air and gases up to temperatures of 200 °C Working pressures up to 4 bar Special applications with other valve insert materials on request

Pre-fabricated STRATE AWASTATION service buildings are set up directly on top of shafts (STRATE AWALIFTSCHACHT) or optionally alongside shafts on concrete foundation blocks. Pre-fabricated solutions offer the possibility of housing system components e.g. shaft cabinets, control elements, electric systems and service connection so that they are easily accessible integrating further optional system components e.g. STRATE AWAaerob ventilation systems, operating data recording and remote transmission etc. One-piece pre-fabricated concrete building, suitable for road and crane transport with four threaded attachment and transport sleeves Re-siting of the service building is possible Inside walls: exposed concrete, painted with washable dispersion paint, colour according to customer wishes Outside walls: textured render, painted in colour according to customer wishes Floor: smooth concrete floor plate with openings for shaft cover, cable duct etc.
