Type HZV is a vertical single or multi-stage submersible centrifugal pump that was specifically developed for pumping hydrocarbons in refueling systems. Common examples of use include the removal of fuels and solvents from underground tanks, the pumping of kerosene in hydrant systems for aircraft refueling and the return of condensate. Due to a wide range of materials, various design variants and shaft seals, HZV pumps are suitable for handling many fluids of not too high viscosity, as long as they are free of solid additives.

The hydraulic pump part is arranged in the vessel or in the pumped medium. The lantern for receiving the drive motor is constructed outside the vessel on a dome cover. The connection is made by a multi-stage shaft and pipe string. The pump and drive shafts are supported in sleeve bearings. The upper drive shaft is fixed by a grease-lubricated, double-sided angular ball bearing. This allows submersible length of up to 15m.
