BTQ - with rectangular hopper

Rectangular, practical – a perfect fit

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.

Features and Benefits

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

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.

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.

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.

Pressure Branch

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

Rotor

Wear resistant and corrosion-proof materials, with additional surface treatment.

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.

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.

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.

Coupling Rod

Coupling rod with a short screw for enhanced product feed, optional with mixing paddels.

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

A square designed hopper with inspection ports on both sides for quick and easy maintenance.

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.

Shaft sealing

Gland packing, alternatively with seal cage ring or grease chamber ring.
