BTM Range

BTM Range

The BTM range pumps have an integrated macerating device in the compression zone which allows for easy processing in subsequent processes.

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.

SEEPEx universal joint protection

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.

SEEPEX metering device

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.
