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

Technologies, accessories and options

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.

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.

Rotor Joint Access (RJA)

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

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.

Pin joint

Robust joint that enables the movement of the rotor. Filled with special grease and fastened with a retaining sleeve. Universal joint sleeves seal the joint, even with extreme temperatures or pumping media. The standard joint for all applications with abrasive products.

Pressure Branch

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

Rotor

Wear resistant and corrosion-proof materials.

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.

Lantern

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

Feed hopper

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

Shutoff system

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

Coupling rod

With progressive pitch auger feed screw for power transmission and feeding of viscous products.

Compression casing

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

Full screw

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