Bungartz MOS & UMOS Centrifugal Pumps
The MOS and UMOS pumps are designed for handling non-toxic media across various industries. They feature a self-sealing, non-contact hydrodynamic shaft seal with an integrated packed gland for when the pump is idle.
- MOS: Optimized for low suction heads, using back vanes for hydrodynamic sealing.
- UMOS: Designed for higher suction heads, equipped with an additional seal expeller to handle inlet pressure.
- M-MOS & M-UMOS: Enhanced with renewable wearing plates for longer service life.
- MOR & UMOR: Feature a centrifugal governor that deactivates the packed gland during operation.
- SK-MOS & SK-UMOS: Welded constructions, ideal substitutes for applications involving low-castable materials.
Application Areas
- Non-toxic, corrosive, abrasive, adhesive, gas-containing, crystallizing & gelling liquids
- Media with solids: phosphoric acid, ammonium nitrate, iron oxide, saline solutions

MPCHDryRun – Magnetic Drive Centrifugal Pump
Heavy-duty chemical pump with magnetic drive, dry-running capability, and grease-lubricated bearings (32,000+ hours life). Designed for maximum safety with advanced shaft seal, back vanes, balance holes, and heat barrier for handling even hot melts.
Application Areas
- Toxic media with strict sealing requirements
- Liquids containing solids
- Gas-containing liquids
Vertical Pumps MPAT & MPCV
Magnetic drive design with no liquid-immersed bearings ensures safe, efficient shaft sealing. MPAT is built for deep submersion, while MPCV suits dry installations under extreme conditions. Self-regulating versions (MPATAN & MPCVAN) available.
Application Areas
- Toxic media with solids
- Gas-containing liquids
- High temperature and/or high pressure
Vertical Submerged Pump T
Special centrifugal pump designed for extreme conditions, ideal for aggressive and abrasive liquids. Features hydrodynamic shaft seal with packed gland as secondary seal; no seals or bearings in the pumped liquid. Self-regulating versions available.
Application Areas
- Non-toxic media with solids (phosphoric acid, ammonium nitrate, iron oxide, saline solutions, wastewater)
- Pit drainage up to 1.4 m depth, safe from dry running
Vertical Pumps VB & VKT
Vertical Submerged Pump VKT
Designed for narrow mounting ports, featuring a hydrodynamic primary seal with optional packed gland or double mechanical secondary seal. Pressure-independent for reliable operation.
Application Areas
- Media with solids (phosphoric acid, ammonium nitrate, iron oxide, saline solutions)
- Installations with narrow mounting ports
VB tank pump and VKT submerged pump are designed for liquids with solids, foam, or gas content. The impeller is top-fed, with shaft sealing by packed gland or seal expeller.
Application Areas
- Sediment-prone liquids with solids
- Foamy and gas-containing liquids
- Mixing and delivering powder + liquid components
