STRATE Valve shafts GRP

STRATE AWALIFTSCHACHT pre-fabricated shafts are used in private, industrial and municipal areas where the installation of sewage pumping stations within existing or planned buildings is not possible. The different design sizes of the pre-fabricated STRATE AWALIFT shafts allow the optimum size to be assigned to every individual AWALIFT pumping station. The possible installation of basement draining pumps in pump sumps is taken into consideration in the shaft dimensions. One-piece compound structure made of glass fibre reinforced plastic (GRP) from a shaft pipe diameter of 1000 mm to 2900 mm, cover and base plate made of reinforced concrete. Absolute water-tightness provides for excellent suitability for further purposes e.g. as an inspection, cleaning or valve shaft. Meets all the requirements of the ATV “Sewage” regulations, which means the pre-fabricated STRATE AWALIFTSCHACHT complies in production and scope of supply completely

The AWALIFT 2/2x2 wastewater pumping system is suitable for towns with up to approx. 2800 residents. The system can achieve a discharge head of up to 120 mWS, thanks to the parallel operation of two pumps. An adapted, intelligent pump controller handles control, ensuring almost fault-free operation. Draining small towns with up to about 2800 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 2 x 2 centrifugal pumps and motors according to type and operating location required Four pump gate valves Two STRATE non-return valves One Y-pipe DN 100 Two pressure pipe gate valves DN 100 Level measurement

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

The BEV-F is a single-stage valve offering only the function of the second ventilation stage (fine ventilation) provided by the two-stage valve (BEV-GF). For ventilation quantities of 20 to 40 m3/h. Specific applications include high points which are under hydrostatic pressure even when the pump is shut down due to the height variation involved, and where no coarse ventilation is required, as well as at high points with low flow quantities. Type F (fine ventilation): Air escapes through this valve, and collected gases cause it to open once again, including under operating pressure, until the medium continues to flow and close the valve again. Installed at high points which are under hydrostatic pressure even when the pump is shut down due to the height variation involved, and where no coarse ventilation is required. Installed at high points of pressure lines with low flow quantities.
