Powerful under extreme conditions: the BTEX hopper pumps SEEPEX are robustly built and designed with reinforced individual components for tough applications – e.g. for fermentation products in the agriculture and biogas industries. They are designed to allow contaminants to settle at the base of the hopper and be removed quickly and easily through large inspection openings for maximum availability and time savings during servicing work.
The rectangular cross section of the hopper design allows contaminants to be separated at the bottom of the hopper
Simply under control
Easy removal of contaminants through large inspection openings in the hopper and compression zone
Maximum availability
Through regular, simple removal of contaminants
Easy maintenance
Quick and simple maintenance thanks to the sliding compression casing
Time-saving
The joints installed in the pump are exclusively universal joints – for very rapid replacement during servicing
Simply clean
Simple cleaning or infeed of liquids via integrated flange opening in the hopper
Technologies, Accessories and Options
Technology
Accessories
Options
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.
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.
Compression housing
Acts as a solids separator to remove foreign matter and is easily removable for quick and easy maintenance.
Robust joint protection with conveying flights
Protects the joint from damage and penetrationof fibrous foreign solids. Additional blade ensureoptimum product infeed.
Flange connection
Connection for feeding the liquid phases or for cleaning / draining.
Screw conveyor
High flow screw auger for thorough mixing and optimum product infeed via a special pitch and solid conveying flights.
Open hopper
Large cross sections and inspection opening along with a solids separator so tramp materials can be easily removed.
Inspection opening
Large inspection openings allow easy removal of any separated solids.
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.
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.
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.
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.
