When media are inclined to bridging, smooth product delivery to the conveying elements cannot always be assured. The BTI hopper pumps from SEEPEX provides a solution. The rectangular hopper contains two counter-running paddle shafts equipped with their own drive system. These mix highly viscous media so thoroughly that bridging cannot even begin to take place – ensuring optimal delivery of the medium to the pump at all times.
NO BRIDGING Thanks to the bridge breaker consisting of two counter-rotating paddle shafts, which keep the medium in constant motion
OPTIMUM PRODUCT CONVEYANCE Feed flow to the screw conveyor is guaranteed, even for highly viscous products, thanks to bridge breaker
FLEXIBLE CONTROL Flexible adjustment of speed thanks to separate drive system for bridge breaker – irrespective of pump speed
EASY MAINTENANCE Quick and simple maintenance thanks to the easy dismantling of the compression casing
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.
Separate Drive
For bridgebreaker, which can be operated with different speed than the pump.
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.
Compression casing
Conical casing ensures optimal feeding of the medium into the conveying elements. Optional sliding compression casing for quick and easy maintenance.
Bridgebreaker device
Integrated bridge breaker device with a rotating paddle shaft to mix for very viscous media tending to build bridges.
Full screw
Auger feed screw reduces backflow of medium, ensuring optimized filling of the pump cavities.
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.
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.
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.
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.
