BTEI - with bridge breaker in the buffer tank

Perpetual motion

No stoppages, no bridging: to ensure the feed medium can be optimally pumped at all times, there is a bridge breaker above the screw conveyor in the rectangular hopper of the BTEI hopper pump from SEEPEX. The separately driven rotating paddle keeps the medium in constant motion, thus avoiding the formation of bridges. A further benefit of the range: in order to save space in the processing system, a closed buffer tank can optionally be connected. A separate reservoir is therefore not required.

Features and Benefits

Space-saving

The optional integrated buffer tank replaces the separate reservoir tank saving space in the processing system

No bridging

Thanks to the bridge breaker, which consists of a rotating paddle shaft, the medium is in constant motion

Optimum product conveyance

Feed flow to the screw conveyor is guaranteed, even for highly viscous products, thanks to bridge breaker

Flexible control

Flexible adjustment of speed thanks to separate drive system for bridge breaker – irrespective of pump speed

Process control

Optional: Installation of various sensors for processing monitoring, e.g. for checking filling level

Dry running protection / TSE

TSE monitors the temperature of the rotating stator and shuts down the pump when the limit value is reached to protect the pump from dry running.

Retensioning device

With this device, a worn stator can be evenly readjusted at several points so that the clamping between the rotor and stator is once again optimal and the pump performance increases.

Overpressure Protection

The pressure gauge switches off the pump as soon as a pre-set pressure is exceeded or not reached and protects the pump from increased wear and tear or piping damage.

Standard base plate

Short base plate B with geared motor for all standard applications.

Universal joint sleeve protection

Stainless steel protective housing protects the universal joint sleeve from mechanical destruction by rough parts made of plastic, metal, wood, etc. Up to 10,000 operating hours guaranteed.

Standard gland packing

Universal seal for hopper and standard pumps for sealing the plug-in shaft and suction casing or feed hopper. Also available with grease or lantern ring to shut off the media flow. Can also be supplied with upstream labyrinth seal and additional flush connection or lubricating device.

Cartridge mechanical seal

Ready-to-install pre-assembled units with supply connections and attachment brackets for quick replacement.

Single-acting mechanical seal

Universal standard mechanical seal for dosing, food applications and semi-submersible pumps for sealing the plug-in shaft in the suction casing or the hopper.

Drive

Geared motors, variable speed drives or frequency controlled motors of all major manufacturers, directly flanged to the pump without additional couplings or guards. Covers made of stainless steel are available.

Lantern

For connection of pump and drive and to secure the assembly to the base plate or directly to the foundation.

Bridgebreaker device

Integrated bridge breaker device with a rotating paddle shaft to mix for very viscous media tending to build bridges.

Ribbon screw

Concentric feed screw with maximized pitch length which self cleans the hopper walls, prevents bridging of the medium in the feed hopper and enhances feeding of the pumping elements.

Compression casing

Conical casing ensures optimal feeding of the medium into the conveying elements. Optional sliding compression casing for quick and easy maintenance.

Stator

The seal on both ends is moulded as an integral part of the elastomeric stator; corrosion of the stator tube is never a problem because the pumped liquid never comes into contact with the metal tube or the bonding adhesive. Available with optional adjustable stator retensioning device.

Conventional geometry

With short pitches and a compact design, the conventional geometry produces high pressures.

6L geometry

With a small rotor diameter and a long pitch, the 6L geometry attains lower surface velocities and extends the service life due to its large sealing line.

Separate Drive

For bridgebreaker, which can be operated with different speed than the pump.

Rotor

Wear resistant and corrosion-proof materials.

Conventional geometry

Pressure Branch

With gauge connection. Flange connections alternatively to DIN or ANSI.
