BTEI - Hopper pump 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.
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
Technologies, Accessories and Options
Technology
Accessories
Options
Pressure Branch
With gauge connection. Flange connections alternatively to DIN or ANSI.
Rotor
Optimized compression between the rotor and stator using wear-resistant and corrosion-resistant materials. A wide range of alloys, coatings and elastomers are available for each.
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.
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.

Compression casing
Conical casing ensures optimal feeding of the medium into the conveying elements. Optional sliding compression casing for quick and easy maintenance.
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.
Bridgebreaker device
Integrated bridge breaker device with a rotating paddle shaft to mix for very viscous media tending to build bridges.
Lantern
For connection of pump and drive and to secure the assembly to the baseplate or directly to the foundation.
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.
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.
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.

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