BTH Range

BTH Range

SEEPEX BTH range pumps combine various advantages from product group T. They feature a separately driven, centric running ribbon screw with a maximized diameter and variable pitch.

Conveying Medias

  • For highly viscous, semi-solid and shear-sensitive products that tend to bridge


  • Conveying capacity: 0.5 m³/h – 130 m³/h (2.2 USGPM – 572 USGPM)
  • Pressure: up to 36 bar (525 psi)
  • Separately driven, centric and edge running ribbon screw with maximized diameter and sustained pitch
  • Separate adjustment of the conveying screw’s speed
  • Maximized, sustained pitch of the auger feed screw
  • Rectangular open hopper with vertical walls, length adjustable to the operating conditions


  • For almost all conveying products including ones that bridge (wide-open screw)
  • Ideal for all shear-sensitive media
  • Optimum filling of the conveying elements through a cylindrical/conical compression zone
  • Easy maintenance: compression casing can be dismantled for service work


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.
