Rectangular upstream process systems require perfectly fitted hopper solutions. With its large rectangular hopper, the BTQ hopper pump from SEEPEX can easily be installed e.g. under thickeners in wastewater treatment plants. A screw conveyor on the coupling rod supports onward transport into the rotating unit. Alternatively, the coupling rod can also be fitted with mixing blades. As the dimensions of the BTQ hopper pump and the BN standard pump are identical, they are readily interchangeable.
EASY MAINTENANCE Easy accessibility to the coupling rod and hopper through inspection ports mounted on the sides of the hopper
OPTIMUM PRODUCT CONVEYANCE Optimal conveyance to the rotating unit by a very short screw conveyor installed on the coupling rod in the hopper – with optional mixing blades
VARIABLE Available in block design with directly flanged-on drive system, or as a variant with free bare shaft and plug connection
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.
Conventional geometry
With short pitches and a compact design, the conventional geometry produces high pressures.
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.
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.

Coupling rod
Coupling rod with a short screw to improve product supply, optional with mixing paddles.
Feed hopper
A square designed hopper with inspection ports on both sides for quick and easy maintenance.
Shaft sealing
Gland packing with or without flushing/seal cage ring or single or double mechanical seals.
Lantern
For connection of pump and drive and to secure the assembly to the baseplate or directly to the foundation.
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.

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.
Retrofit Kit SCT
With the Retrofit Kit, many standard and open hopper pumps can be upgraded to Smart Conveying Technology (SCT).
Standard base plate
Short base plate B with geared motor for all standard applications.
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.
