Pre - Import export

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

SCHÜTZE Control valve for pre- / purging air Our new external control valve combined all demands. It works pneumatically. It receives from a separate 3/2 way solenoid valve an air pulse of 5 - 6 bar. This pulse starts the atomizing air, which can be reduced by the assembled pressure regulator to the needed air pressure. Delayed starts the control air without pressure reduction (5 - 6 bar). The closing process takes place in reverse order.
