BTES - HOPPER PUMP FOR SILO SYSTEMS

PERFECT FOR ANY SILO

Made for silos: With their long hoppers, BTES hopper pumps from SEEPEX are ideal for installation under a silo. The construction of the rectangular hopper can then be optimally adapted to a wide variety of silo discharge systems. The pumps are ideal for pumping e.g. dewatered sewage sludge to drying or combustion plants. In order to ensure that the silo does not need to be fully emptied before maintenance, the pump is fitted with a closure system behind the hopper – this saves time and money.

Features and Benefits

A perfect fit

Structural optimization of the hopper for a perfect fit under the respective silo

No silo emptying

Thanks to integrated closure system in the pump that keeps out non-flowable, semi-solid media, the pump can be maintained wihtout silo emptying

Time-saving

Maintenance time reduced many times over by eliminating the time-consuming silo emptying process

Easy maintenance

Quick and simple maintenance thanks to the easy dismantling of the compression casing

No bridging

Thanks to the shallow design of the hopper

Optimum product conveyance

Conveyance of the optimal flow rate to the downstream rotating unit by compressing the medium in the compression zone

  • 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.

  • Dry-running protection device (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.

  • 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.

  • Rotor Joint Access (RJA)

    Sliding separate casing with enlarged cross section ensures quick and easy maintenance.

  • 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.

  • 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.

  • 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.

  • Conventional geometry

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

  • 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.

  • Compression casing

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

  • Shutoff system

    For easy maintenance without having to completely empty the silo. Especially for highly viscous products.

  • Feed hopper

    With minimized hights to prevent bridging and large hopper length. This ensures optimal feeding of the medium.

  • Full screw

    Auger feed screw reduces backflow of medium, ensuring optimized filling of the pump cavities.

  • 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.
