BTVE - with robust full screw

From highly viscous to semi-solid

BTVE hopper pumps from SEEPEX provide the ability to transport dewatered sludge with a dry matter content of up to 30%. A large, rectangular intake hopper with screw conveyor allows them to easily be fed with highly viscous and semi-solid products with no tendency towards bridging. A roller-mounted sliding compression casing further simplifies dismantling, thus allowing the cleaning and maintenance of the rotating unit.

Features and Benefits

Easy maintenance

Simplified access to joint and rotor thanks to roller-mounted sliding compression casing

Easy to clean

Fast and powerful cleaning of all parts in the hopper via flange connections mounted directly on the intake hopper

Adaptable

Length of rectangular intake hopper adjustable to upstream components

Optimum product conveyance

Optimal conveyance of the product to the downstream rotating unit via a screw conveyor installed in the hopper with a large diameter and long pitch

Variable

Available in block design with directly flanged-on drive system, or as a variant with free bare shaft and plug connection

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.

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.

Cartridge mechanical seal

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

Drive Joint Access (DJA)

The optional sliding casing allows access to the drive side's universal joint for quick 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.

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.

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.

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.

Rotor Joint Access (RJA)

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

Feed hopper

With vertical hopper walls to prevent bridging or clogging and a generous cross section. The hopper length can be individually fabricated.

Auger feed screw

Designed with increased blade thickness, a long pitch and enlarged diameter for optimal product feeding.

Flush connection

Connection for cleaning, emptying or diversion.

Shaft sealing

Packing or mechanical seals are available in many material combinations.

Lantern

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