Sentrimax supplies decanter and tricanter centrifuge parts, from individual wear components to full rotating assemblies, built to meet or exceed OEM specifications. Its machine shop can also design new or reverse-engineered parts when original tooling is unavailable. Parts support machines from 8 to 43 inches in bowl diameter across major brands including Sharples, Flottweg, Centrisys, GEA and Alfa Laval.
What a decanter centrifuge parts supplier actually needs to deliver
Parts sit alongside the rest of Sentrimax’s centrifuge maintenance,
repair and overhaul services rather than as a separate business — the same inspection and
engineering capability used on a full repair applies to a standalone parts order. A centrifuge is
only as reliable as the parts that go back into it after a rebuild. Ordering
the wrong tolerance on a scroll tip, a bearing rated for the wrong load, or a seal compound that
does not match the process fluid turns a routine parts order into an unplanned second shutdown.
Sentrimax supplies parts for decanter, tricanter and disc stack centrifuges from 8 to 43 inches in
bowl diameter, and treats the parts side of the business with the same inspection discipline used
on a full overhaul: dimensional verification against OEM tolerances, material traceability, and
where the job calls for it, dynamic balancing before the part ships.
Piezas fabricadas para cumplir o superar las especificaciones del fabricante original.
Every parts package Sentrimax supplies is manufactured or refurbished to meet or exceed OEM
specifications. That standard is applied whether the part is a stocked wear item, a component
pulled from a full rotating assembly rebuild, or a piece reverse-engineered because the original
manufacturer no longer supports the model. In practice this means the part is measured against
the same critical fits and finishes documented during Sentrimax’s own inspection process, not
against a generic aftermarket catalog spec.
For buyers new to independent MRO, the natural next question is how that standard is verified
and where OEM sourcing still makes more sense than an aftermarket part. That comparison is covered
in full on Sentrimax’s guide to aftermarket versus
OEM centrifuge parts, which sets out what to ask a supplier for and where staying with the
original manufacturer is still the right call.
Engineering services and machine shop: new and reverse-engineered parts
Not every part is available off the shelf. Older machines, discontinued model lines, and
custom-configured units sometimes have no active OEM parts program at all. Sentrimax’s engineering
services and machine shop group performs milling, lathe-turning and precision grinding in-house,
and can design a new part or reverse-engineer one from the original when drawings or OEM support
do not exist. This is the same capability that supports full rotating assembly rebuilds during a
shop overhaul, applied at the individual part level when that is all a customer needs.
Wear parts
Scroll flights and tiles, feed zone liners, bearings,
seals and discharge components sized to the original centrifuge’s critical fits.
Rotating assembly components
Bowl, scroll and shaft components
machined to OEM tolerance and dynamically balanced where the scope requires it.
Caja de cambios y piezas de transmisión
Components for planetary (2- and 3-stage)
gearboxes, CYCLO gearboxes and hydraulic backdrives.
New or reverse-engineered parts
Designed and machined in-house
when original tooling, drawings or OEM support are no longer available.
Which wear parts fail first
Some components on a decanter centrifuge wear predictably and on a shorter cycle than the rest
of the machine. Knowing which ones, and what failure signature each one leaves behind, makes it
easier to order the right part before a routine wear issue turns into an unplanned outage. Sentrimax
has put together a ranked breakdown of the parts most likely to need replacing and what each failure
mode signals in the guide to centrifuge wear parts.
Equipment and brands supported
Sentrimax is an independent service and parts provider, not affiliated with, authorized by or
endorsed by any centrifuge manufacturer. Brand names describe the equipment supported, nothing
more. Parts are supplied for decanter, tricanter and disc stack centrifuges from major brands
including Sharples, Flottweg, Centrisys, Derrick, GEA, Alfa Laval, Tomoe, Andritz, Bird and
Pieralisi, among others, across the 8 to 43 inch bowl diameter range.
Gearbox and drive-side parts
Wear and repair parts are not limited to the wetted end of the machine. Sentrimax supplies
components for the drive side as well, covering planetary gearboxes in both 2- and 3-stage
configurations, CYCLO-style gearboxes, and hydraulic backdrives. Drive-side parts carry their own
identification requirements, since gearbox ratio and configuration vary even within a single bowl
diameter class, which is one of the reasons a photograph of the installed gearbox, not just the
main nameplate, is useful when requesting a quote for these components.
Full rotating assembly versus individual component replacement
Some repair scopes call for a full rotating assembly — bowl, scroll and shaft rebuilt and
balanced as a unit — rather than individual component replacement. Sentrimax’s engineering
services and machine shop supports both: a full assembly rebuild when wear or damage is extensive
enough that individual replacement no longer makes sense, and targeted component-level parts
orders when the rest of the assembly remains within tolerance. Which approach applies depends on
the inspection findings, not a fixed rule, which is why a documented inspection report, produced
on every job, matters even for parts-focused work.
Getting an accurate parts quote
The fastest way to a correct parts quote is a clear identification of the machine: manufacturer,
model designation and bowl diameter, plus the nameplate or serial number where it is legible. A
customer who is not sure how to read a data plate, or who has a machine with a worn or missing
nameplate, can work through the guide to identifying a
centrifuge model and parts before requesting a quote. That step alone removes most of the
back-and-forth that slows down a parts order.
Ordering without a full overhaul
A parts order does not require sending the whole centrifuge in for a rebuild. Sentrimax quotes
individual wear parts, rotating assembly components and gearbox parts directly, based on model
identification and, where useful, photographs of the worn component.
Full overhaul, equipment and part sales
Beyond individual parts and rotating assembly components, Sentrimax’s full overhaul and
equipment sales capability covers complete centrifuge packages with ancillary equipment, gearboxes
and electric components, for plants replacing rather than repairing a unit, or adding capacity
alongside an existing fleet. This sits at the far end of the same parts and engineering capability
described above, scaled up to a full machine rather than a single component.
Documentation that comes with a parts order
Parts supplied as part of a repair scope are documented within the same reporting Sentrimax
provides on any job: an inspection report where relevant, and an invoice that itemizes what was
supplied. Keeping this documentation with the equipment’s maintenance file makes the next parts
order faster, since the model identification and prior specification are already on record rather
than needing to be re-established from scratch.
What every Sentrimax repair and parts job includes
- Fit evaluation against the original machine’s critical dimensions
- A detailed inspection report where the part is supplied as part of a repair scope
- Dynamic balancing where the part is part of a rotating assembly
- A test run before the assembled unit ships, on full overhaul work
What milling, lathe-turning and precision grinding actually change
These three processes sound generic until you connect them to what fails on a centrifuge.
Lathe-turning produces the round, concentric surfaces a shaft or bowl section needs to run true at
operating speed; a part that is slightly out of round will not balance correctly no matter how
carefully it is installed. Milling cuts the flat faces, keyways and mounting features that let a
new or reverse-engineered part bolt up exactly where the original one sat. Precision grinding
brings critical fits — bearing seats, seal faces, shaft journals — down to the tight tolerance
those surfaces need to seal and run without excess clearance. A parts supplier that only stocks
finished components without in-house machining has no way to correct a part that is close but not
quite right; Sentrimax’s machine shop can adjust or remanufacture rather than reject and re-order.
Parts demand tracks the process, not just the machine
How hard a centrifuge is on its own parts depends heavily on what it is separating. Sentrimax
supports centrifuges across municipal water and wastewater treatment, environmental services and
contaminated soil handling, general dewatering, energy and utilities including drilling mud and
produced water, food and beverage processing, mining and mineral recovery, and several other
industrial sectors. A unit dewatering abrasive mineral tailings wears scroll flights and tiles at
a different rate than one running dairy separation, even on an identical frame size, because the
solids content and abrasiveness of the feed differ. This is one reason a generic replacement
interval is less useful than watching your own machine’s performance trend and ordering parts
based on what you are actually seeing.
How a parts order typically moves
- Identification. Confirm manufacturer, model and bowl diameter, ideally from a
nameplate photograph or physical measurement. - Scope. Describe the part needed or the symptom driving the order, with
photographs of the worn or failed component where available. - Review and quote. Sentrimax confirms fit against the machine’s critical
dimensions and quotes the part, noting whether it is a stocked item, a manufactured part, or a
reverse-engineered design. - Verification before shipment. Dimensional and, where applicable, material
verification is completed before the part leaves Sentrimax, with dynamic balancing for rotating
components. - Entrega. Parts are shipped through Sentrimax’s broker network, with
documentation covering what was supplied.
Requesting parts across North America

Preguntas frecuentes
Can I order centrifuge parts without sending the whole machine in for an overhaul?
Yes. Sentrimax quotes individual wear parts, rotating assembly components and gearbox parts directly. Providing the machine's model, bowl diameter and, where possible, photographs of the worn part lets Sentrimax confirm fit before anything ships, without requiring a full teardown or shop visit.
Do you carry parts for older or discontinued centrifuge models?
Sentrimax's engineering services and machine shop can design new or reverse-engineered parts when a model is no longer supported by the original manufacturer or when drawings are unavailable. Parts are machined in-house using milling, lathe-turning and precision grinding rather than sourced from a limited stock catalog.
Are Sentrimax parts made by the original equipment manufacturer?
No. Sentrimax is an independent MRO provider and is not authorized by, affiliated with or endorsed by any centrifuge manufacturer. Parts are engineered and manufactured to meet or exceed OEM specifications, verified against the same critical fits and tolerances used in Sentrimax's own repair process.
What information do you need to quote a part accurately?
The manufacturer, model designation and bowl diameter, ideally read from the nameplate or stamped serial number, plus a description or photograph of the part needed. Buyers unsure how to read their nameplate can use Sentrimax's model identification guide before requesting a quote.
Do centrifuge parts come with any verification before they ship?
Parts supplied as part of a repair scope go through the same fit evaluation, inspection documentation and, where applicable, dynamic balancing and test run used across every Sentrimax job. Individual stock parts are checked against the critical dimensions and specifications of the original component.
