The Wilo Multivert MVIS 403 is a compact, multistage vertical pump with an inline design, engineered for water supply and pressure boosting in systems with clean or potable water. Thanks to its wet-running motor with direct drive, the pump operates extremely quietly, which is appreciated by users in both residential and commercial properties.

All parts in contact with the medium are made of stainless steel, ensuring the pump meets hygienic requirements for drinking water (EPDM). Its seal-less design makes it almost maintenance-free, and connection via oval flanges ensures quick installation. The 1.1 kW power output is ideal for smaller pressure assemblies or standalone applications.
