Product Summary

Genuine and compatible spare parts for the SEEPEX BT, the all-rounder open hopper pump with a rectangular hopper, compression zone and auger feed screw, used in Australia for thickened sludge, food waste and other highly viscous, low-flow products. Every BT shares the same build (rotor, stator, coupling rod with auger, pin joints and shaft seal), so tick what you need and we’ll match the parts to your nameplate, such as BT 05-24.

Type: Progressive cavity, open hopper Build: Rectangular hopper · compression zone · auger feed screw Range: 0.1–150 m³/h · up to 36 bar

Spare Parts List

✓ Tick the parts you need. SEEPEX parts are matched to the pump range, size, rotor/stator geometry, stator elastomer and shaft seal, so the type code and the commission number on your nameplate are all we need to get them right. Not sure which items? Add a photo of the nameplate and we’ll work it out for you.

SelectWear / Service ItemFunction & when to replace
Common Service Kits
Minor Set of Wearing PartsSEEPEX’s minor wear set for the BT: flushing ring (311) and stator (601).
Major Set of Wearing PartsPlug-in shaft, rinse ring, coupling rod with bushings, coupling rod pins, guide bushings, universal joint sleeves, holding bands, rotor and stator.
Set of GasketsMechanical seal (330), casing gasket (501) and sealing rings (503, 706). Renew whenever the pump is opened.
Complete Set of Joint Parts (items 401–407)Retaining sleeve, coupling rod pins, guide bushings, universal joint sleeves and holding bands for both pin joints.
Wear & Consumable Parts
Stator (item 601)The elastomer-lined pumping element and the part that wears most. Replace when flow or pressure drops away, after any dry run, or if the elastomer has swollen, hardened or torn.
Rotor (item 600)The helical rotor that turns inside the stator. Replace if it is scored, pitted or worn through its coating; a worn rotor will chew out a new stator quickly.
Mechanical Seal (item 330)The shaft seal at the drive end of the suction casing (gland packing on some builds). Replace at the first sign of leakage; check the seal faces and O-rings for wear and chemical attack.
Pin Joint Grease (item 098)SEEPEX special joint grease. The manual calls for fresh grease every 10,000 operating hours and at every joint rebuild; SEEPEX specifies its own grease only.
Casing Gasket (item 501)Seals the stator to the suction casing. Fit a new one every time the stator is changed.
Other Core Parts
Coupling Rod with Auger Feed Screw (item 400)Carries the drive from the plug-in shaft to the eccentric rotor through a pin joint at each end. Replace if the bores are worn oval, the rod is bent, or corrosion has attacked it.
Plug-in Shaft & Pin (items 307, 309)The plug-in shaft that connects the drive to the coupling rod and carries the shaft seal. Replace if it is worn or grooved under the seal or damaged at the joint end.
Flushing / Rinse Ring (item 311)The ring at the shaft seal that is flushed to keep product off the seal. Replace if worn or blocked.
Feed Hopper & Compression CasingThe rectangular hopper and compression zone that feed product into the rotor/stator. Replace if worn through or cracked.
Pressure Branch (item 700)The discharge end casing that clamps the stator. Replace if worn or cracked, or when changing connection size.
Drive Unit (gearmotor)The flanged gearmotor (block design) or the separate drive train on bare-shaft builds. Matched to your kW, output speed and mounting so the replacement bolts straight on.
Complete Replacement PumpWhen a rebuild doesn’t stack up, we quote a like-for-like SEEPEX BT hopper pump from the type code and commission number on your nameplate.

How we confirm the exact part: SEEPEX BT parts depend on the size, rotor/stator geometry, stator elastomer, rotor material, joint type and shaft seal fitted to your pump. The item numbers shown are the positions in the SEEPEX parts list; your nameplate carries the type code (e.g. BT 05-24) and the commission number, which together pin down the build. Tick the items above and add a nameplate photo, and we’ll confirm the correct parts for your exact pump.

Troubleshooting

Pump runs but delivers little or nothing

Likely cause: worn stator and rotor, a blocked suction line, or speed too high for a viscous product (cavitation). Action: clear the suction line and check the speed against the duty; if output is still down, replace the stator (item 601), and the rotor (item 600) if it is scored.

Stator wears quickly or burns out

Likely cause: dry running, solids or grain size too large for the pump speed, or product temperature too high for the elastomer. Action: fit a new stator, reduce speed or screen the feed, keep the pump full at start-up and fit dry-run protection; SEEPEX also suggests an undersize rotor for hot duties.

Pump hard to turn or will not start after a stator change

Likely cause: stator swollen by an incompatible product, or product that has settled, gummed up or set inside the pump while it stood. Action: check the stator elastomer against the product and select a suitable material; rinse and clean the pump immediately after stopping, and heat it if the product hardens when cold.

Product bridges in the hopper and the pump starves

Likely cause: very stiff or sticky product not falling onto the auger, or a worn auger feed screw. Action: check the hopper feed and auger for wear, consider dilution or a bridge-breaking hopper option, and keep the speed within the product’s limits.

Knocking or noise from the suction casing

Likely cause: worn joint parts or too much joint play, often with grease lost through a split joint sleeve. Action: renew the complete set of joint parts with SEEPEX pin joint grease and check the coupling rod bushings are correctly fitted.

Leaking at the shaft seal

Likely cause: a worn mechanical seal (sliprings or O-rings) or packing that is worn or set too tight. Action: check the sliprings and O-rings for wear and chemical resistance and renew the seal; on packed pumps adjust the gland or renew the packing rings.
