BN Range
The BN range pumps have a modern, compact, low-cost and user friendly design.
Properties
- Conveying capacity: 30 l/h – 500 m³/h (0.132 USGPM – 2,200 USGPM)
- Pressure: up to 48 bar (700 psi)
- Short, compact design with directly flange-mounted drive (block type)
- Enhanced combination options: block design available in all sizes and pressure stages
Benefits
- Low-cost due to the removed bearing frame, flexible coupling and common base plate
- Easy maintenance due to the plug-in connection between the rotating unit and drive
- Separate pump bearing omitted
DRIVES & BASE PLATES
The figures below are examples to demonstrate the various drive and baseplate versions. seepex pumps can be delivered with geared motors, variable speed drives and frequency-controlled drives of all well-known manufacturers. The drive types can be used for all ranges.

Base plate API 676 (NS) with geared motor
Accessories
Our guarantee: this stainless steel protection shields the universal joint sleeve from mechanical damage from oversized plastic, wooden, glass or metal parts. SEEPEX joints with universal joint protection are also guaranteed 10,000 operating hours.
For a long pump service life: a temperature sensor installed in the stator checks the temperature between rotor and stator and compares it to the limit temperature set in the TSE control. When this value is reached, the control switches off the pump and triggers an alert.
The SEEPEX dry-running protection device monitors the temperature of the stator during operation and protects it from premature wear by switching off the pump when the limit is reached.
Help against wear: with the stator tensioning device, a worn stator can be evenly retightened so that the original compression between the rotor and the stator is restored and the pump performs again at its full capacity.
Protection against over-/underpressure: a diaphragm pressure gauge with open flange for highly viscous media switches as soon as the pressure drops below or exceeds the set value.
For precise metering: with this metering device you can set the required number of rotations, making it possible to adjust the flow rate to the exact requirements.
For shaft seal protection: the seal barrier system is fed with a buffer liquid. Upon request, it can be equipped with a flow meter that ensures trouble-free operation.
