MDT Range

MDT Range

SEEPEX MDT range pumps have an open hopper with cylindrical compression zone. The auger feed screw on the coupling rod feeds the viscous product to the rotor and stator.

For highly viscous products with low flowability


  • Conveying capacity: 5 l/h – 500 l/h (1.32 USGPH – 132 USGPH)
  • Pressure: up to 24 bar (350 psi)
  • Open hopper pump with compression zone and auger feed screw


  • High volumetric efficiency with optimum filling of the conveying chamber due to the system pressure produced in the compression zone


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.

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.
