WALTRAUT STÜRMER

The AWALIFT 2/2 penta is available in two power levels. The first option offers system power of - up to 25 m3/h for up to 1200 residents and - up to 36 m3/h for up to 1700 residents Despite their small size, the wastewater pump stations offer all the advantages of the AWALIFT series: - our trusted bulk materials collecting chamber system, dry set-up, and thanks to their good power levels, they can move wastewater across long distances. Different motor variants allow the system to be precisely adjusted to your needs. Area of use Draining small towns with up to about 1200 residents which cannot be drained using natural gradient or as an intermediate pumping station within the context of a pressure drainage system Residential and industrial areas Towns Communities Infrastructure facilities such as airports, industrial parks, underground stations etc. Product features One holding tank with two separator systems Two centrifugal pumps and motors according to type

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.
