Seepex® Open-Hopper Pump Components

Seepex® BT Hopper Pump Parts

Model-based replacement rotors, stators, feed screws, coupling components, drive parts, seals and hopper-related wear components for supported Seepex® BT-family pumps.

BT-family constructions vary by hopper geometry, feed-screw arrangement and material-handling features. Selection begins with the complete model and required component, supported by dimensions and photographs.

Replacement Parts for Seepex® BT Hopper Pumps

Seepex® BT-family pumps combine a progressive cavity pumping element with an open or rectangular hopper and a feed mechanism that moves viscous, non-flowing or solids-bearing material toward the rotor and stator. The construction may use a screw conveyor, full screw, ribbon screw, bridge breaker, macerating system or other application-specific feeding arrangement.

Because the hopper and feed components vary substantially across the family, a general pumping-element size is not enough to identify every replacement. The complete model, hopper construction, screw arrangement, connection details, materials and critical dimensions must be reviewed.

ACCA evaluates supported BT-family components using model information, photographs, dimensions, drawings and physical samples when required. Process consistency, solids, temperature, abrasiveness, differential pressure and operating speed also influence component and material selection.

BT identification rule: send the complete pump model and identify whether the request is for the pumping element, feed screw, coupling assembly, drive component, seal, hopper component or another part. Include photographs and dimensions of the installed construction.

Seepex® BT Hopper Pump Constructions

The BT range contains multiple hopper and feed-system configurations. ACCA reviews replacement availability for the specific model and component rather than assuming parts interchange across these constructions.

BT and BTQ

Standard highly viscous-media hopper pumps and rectangular-hopper configurations.

BTBTQViscous MediaRectangular Hopper

BTI and BTEI

Hopper configurations incorporating bridge-breaking equipment to support difficult material entry.

BTIBTEIBridge Breaker

BTVE and BTEX

Robust screw and heavy-duty constructions used for highly viscous, semi-solid or demanding service.

BTVEBTEXFull ScrewHeavy Duty

BTH and BTHE

Ribbon-screw arrangements requiring confirmation of screw geometry, drive and hopper construction.

BTHBTHERibbon Screw

BTM and BTES

Integrated macerating and silo-discharge systems with specialized feeding and preparation components.

BTMBTESMacerationSilo Discharge

BTCS and Legacy Variants

BT Replacement Components

Rotors

Replacement rotors reviewed for model, pumping-element geometry, material, coating and dimensions.

Stators

Replacement stators selected around model, geometry, elastomer, fluid, temperature, solids and pressure.

Feed Screws and Augers

Screw-conveyor and auger components evaluated from complete model, geometry, dimensions and material.

Ribbon Screws

Separately driven and edge-to-edge ribbon-screw components reviewed for the installed construction.

Coupling Components

Coupling rods, pins, bushings, sleeves, retainers and related torque-transmission parts.

Drive Shafts

Replacement shafts confirmed from model, drive arrangement, keyway, seal surface and dimensions.

Seals and Packing

Mechanical seals, packing and related sealing components evaluated for the installed arrangement.

Hopper Wear Components

Selected hopper, compression-zone and feeding components reviewed using model and dimensional data.

Special and Legacy Parts

Uncommon components evaluated using photographs, accurate measurements, drawings or samples.

BT Component Identification

Identification Item Information Needed Why It Matters
Complete BT-family model Every letter, number and suffix Distinguishes hopper, screw, bridge-breaker and other construction types
Required component Pumping element, feed screw, coupling, seal, hopper or other part Determines the measurements and construction details required
Feed-system geometry Photographs, overall dimensions, pitch, diameter and connection details Separates full screws, ribbon screws, augers and specialized arrangements
Rotor and stator Geometry, dimensions, materials and service history Affects pressure, capacity, starting torque, wear and sealing
Process material Consistency, solids, temperature, abrasiveness and chemistry Supports material and feeding-component selection
Drawing or sample Available drawing or physical worn component May be necessary for modified, special or legacy parts

How to Request Seepex® BT Parts

1. Record the full model

Provide the complete BT-family designation exactly as shown on the equipment documentation.

2. Identify the assembly

State whether the request involves the pumping element, screw, drive train, seal, hopper or another component.

3. Photograph the construction

Include overall equipment views plus close-ups of connections, ends and distinguishing features.

4. Supply dimensions

Provide overall length, diameters, pitch, connections, shaft details and other critical measurements.

5. Describe the material

Include product consistency, solids, temperature, abrasiveness, chemistry and operating conditions.

Typical BT Hopper Pump Applications

Dewatered Sludge

Filter-press, belt-press and screw-press cake requiring assisted feed into the pumping element.

Food and Organic Waste

Viscous, fibrous and solids-bearing products requiring hopper and screw-conveyor handling.

Biogas Feedstock

Organic material, biomass and waste streams introduced into digestion and processing systems.

Pulp and Paper

High-consistency stock, broke, sludge and fibrous process materials.

Mining and Minerals

Thickened slurry, paste and abrasive material requiring positive-displacement transfer.

Highly Viscous Products

Adhesives, sealants, dough-like products and other materials that do not readily flow into a pump.

Frequently Asked Questions

What information identifies a Seepex® BT replacement component?

Send the complete model, required component, overall equipment photographs and detailed dimensions. Feed screws and special components may require a drawing or physical sample.

Are parts interchangeable across BT, BTQ and BTI pumps?

Do not assume interchangeability. Hopper geometry, feeding arrangement, drive components and dimensions can differ. ACCA reviews the complete model and requested component.

What BT-family parts can ACCA supply?

Supported components may include rotors, stators, feed screws, coupling and joint parts, drive shafts, seals, packing components and selected hopper-related wear parts.

What measurements are needed for a feed screw?

Useful information includes overall length, outside diameter, shaft and connection details, screw pitch, flight geometry, material and clear photographs.

How are rotor and stator materials selected?

Selection considers the complete model, product chemistry, temperature, solids, abrasiveness, pressure, speed and previous service history.

Can ACCA review a modified or legacy BT component?

Yes, when sufficient photographs, measurements, drawings or a physical sample are available to evaluate the required form, fit and function.
