Mixing Pumps

Mixing Pumps

WITTE mixing pumps are used, among other things, in extinguishing technology. As a dosing and mixing unit, an additive for foam formation is pumped into the main jet of the extinguishing unit. The resulting foam suffocates the fire within seconds.

Mixing pumps for the extinguishing area are special pumps that we have exclusively adapted to the needs of a customer. After a short coordination and development phase and the correct material selection, the old pump could be replaced with a WITTE pump. The service life has been significantly extended. WITTE mixing pumps are used, among other things, in extinguishing technology. As a dosing and mixing unit, an additive for foam formation is pumped into the main jet of the extinguishing unit.
