Pump installation kit Retrofit S Duo, GTF 500-S1, 230V
The pump installation kit, designed for fitting into existing collection tanks for wastewater without sewage, is fitted with one or two continuous-duty, submersible pumps and two backwater preventers. The compact polymer (PU) bracket is designed to accommodate the components flexibly for various application scenarios and to perform fixing of the pumping station even in confined spaces. The supplied 90° connector allows connection to all standard types of pressure pipes. Quick-release closures enable the integrated components to be removed easily. The components are pre-assembled for final installation on site. Control is via a level float using a user-friendly 230V Connect Duo control unit, which can optionally be integrated into the building management system via a potential-free contact.
