The BT hopper pump is the all-rounder in the SEEPEX hopper pump catalog. With its large rectangular hopper, screw conveyor and a compression zone, it effortlessly conveys highly viscous products with low flowability.
OPTIMUM PRODUCT CONVEYANCE Conveyance of the optimal flow rate to the downstream rotating unit by compressing the medium in the compression zone
VARIABLE Available in block design with directly flanged-on drive system, or as a variant with free bare shaft and plug connection
ADAPTABLE Length of rectangular intake hopper adjustable to upstream components
SCT RETROFIT OPTION Can be upgraded with a retrofit kit to use the particularly easy-to-maintain Smart Conveying Technology (SCT)
Technologies, Accessories and Options
Technology
Accessories
Options
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.
Tie bolts/screw
Corrosion proof, optional available in stainless steel design.
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.
Compression zone
Flanges at both ends for quick disassembly when replacing the rotor, hand hole on request.
Screw conveyor
Coupling rod with screw conveyor with progressive pitch for power transmission and conveying of viscous products.
Feed hopper
Rectangular design, hopper length customized to meet special applications.
Joint connection
Consisting of just 5 components. Power transmission through wear resistant, hardened and replaceable joint parts: easily repaired.
Universal joint sleeve with holding bands
Protects the grease-filled joints from penetration of the liquid pumped, even in case of maximum vacuum or pressure loading. Streamlined design to reduce turbulence and NPSHr.
Shaft sealing
Gland packing with or without flushing/seal cage ring or single or double mechanical seals.
Plug-in shaft
Connects the drive shaft to the joint. With gland packing the plug-in shaft is used as a shaft protection sleeve. Upon request, it is available with wear resistant coating.
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.
Retrofit Kit SCT
With the Retrofit Kit, many standard and open hopper pumps can be upgraded to Smart Conveying Technology (SCT).
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.
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.
