BT - Standard hopper pump

The universal genius

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.

Conveying Capacity
0.1–150 m³h
0.44–660 US gpm
Pressure
36 bar
525 psi

Features and Benefits

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

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.

Retrofit Kit SCT

With the Retrofit Kit, many standard and open hopper pumps can be upgraded to Smart Conveying Technology (SCT).

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.

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, with additional surface treatment.

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.

Coupling rod

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

Suction casing

With large cross section and designed for smooth flow conditions, with drain plug and connections for pressure/vacuum gauge. Flange connections in DIN or ANSI can be rotated in 90° increments.

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, alternatively with seal cage ring or grease chamber ring.

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 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.

Compression zone

Flanges at both ends for quick dismantling when replacing the rotor, hand hole upon request.

Feed hopper

Rectangular design, hopper length customized to meet special applications.

Tie bolts/screw

Corrosion proof, optional available in stainless steel design.
