SEEPEX BCSB Hygienic Pumps
Spare Parts for SEEPEX BCSB Food Grade Pumps with Closed Pin Joints
Product Summary
Genuine and compatible spare parts for the SEEPEX BCSB, the food grade progressive cavity pump with closed pin joints sealed by elastomer sleeves, used in Australian food, cosmetics and chemical plants with CIP, SIP and COP cleaning. Every BCSB shares the same build (rotor, stator, coupling rod with sealed pin joints, plug-in shaft and shaft seal), so tick what you need and we’ll match the parts to your nameplate, such as BCSB 17-24.
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.
| Select | Wear / Service Item | Function & when to replace |
|---|---|---|
| Common Service Kits | ||
| Minor Set of Wearing Parts | SEEPEX’s minor wear set for the BCSB: the stator (601). | |
| Major Set of Wearing Parts | Plug-in shaft, coupling rod with bushings, coupling rod pins, guide bushings, universal joint sleeves, holding bands, rotor and stator (splash ring too on the larger sizes). | |
| Set of Gaskets | Small sizes: splash ring (310), casing gasket (501), sealing rings (571, 726) and O-ring (572). Sizes 17-24 to 130-6L: mechanical seal (330) and casing gasket (501). | |
| Complete Set of Joint Parts | Retaining sleeve, coupling rod pins, guide bushings, universal joint sleeves and holding bands for both sealed 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. Hygienic elastomers are FDA / EU 1935-2004 compliant. | |
| 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 Bushings (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. | |
| Splash Ring (item 310) | Keeps leakage and washdown away from the drive. Replace if worn or split. | |
| Suction Casing (item 500) | The inlet casing that houses the joints and shaft seal. Replace if eroded, corroded or cracked, matched to your connection standard. | |
| 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 Pump | When a rebuild doesn’t stack up, we quote a like-for-like SEEPEX BCSB food grade pump from the type code and commission number on your nameplate. | |
How we confirm the exact part: SEEPEX BCSB 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. BCSB 17-24) 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.
Models
The three BCSB operating instructions cover sizes 025-12 to 1-6L, 1-6 to 75-6LT and 17-24 to 130-6L; the size code after BCSB on your nameplate identifies the 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 residue or poor CIP results
Likely cause: worn or damaged casing O-ring or seal letting product lodge, or joints not cleaned. Action: renew the casing O-ring and mechanical seal, check the open joints for damage, and confirm CIP flow and chemistry.
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.
