BAP GmbH Abwassertechnik
About
BAP GmbH Abwassertechnik is a German manufacturer of valves, slide gates, and pipeline fittings purpose-built for wastewater treatment plants and sewer systems. The company's catalog is organized around 17 numbered product families plus an actuator line, each designated by the BAP prefix — a nomenclature that has become standard in German wastewater engineering. Their slide valve range includes the flushing slide valve (BAP 1 Spülschieber) for tank and channel washdown, the hand-pull slide valve (BAP 2 Handzugschieber) for manual open-channel regulation, the threaded slide valve (BAP 3 Gewindeschieber) with screw-spindle positioning, the channel slide valve (BAP 4 Rinnenschieber) for open-channel flow control, the plug-in slide valve (BAP 5 Steckschieber) for quick-insertion applications, and the lowering slide valve (BAP 6 Absenkschieber) for vertical actuation. Beyond slide valves, BAP produces backflow flaps (BAP 7 Rückstauklappe) preventing sewer surcharge reversal, distributor tongues (BAP 8 Verteilerzunge) for flow splitting, overflow edges and weirs (BAP 9 Überfallkante/Überfallwehr) for tank level control, deflector plates and wall pipe fittings (BAP 10 Prallteller/Mauerrohr/Formstück), control throttles (BAP 11 Regeldrossel) with remote actuation, wafer-type slide valves (BAP 12 Zwischenflanschschieber) for flange-to-flange installation, wedge gate and oval slide valves (BAP 13 Keilschieber) for bubble-tight shut-off, hydraulically damped check valves (BAP 14 Rückschlagklappe), shut-off butterfly valves (BAP 15 Absperrklappe) for large-diameter pipelines, pass-through and removal fittings (BAP 16 Pass- und Ausbaustück), flood protection dam beam systems (BAP 17 Dammbalken), and electric or pneumatic actuators (BAP 99 Antriebe). All products are manufactured in stainless and carbon steel for corrosive wastewater environments.
