Reverse Engineered Spare Parts for PFA-Lined Magnetic Drive Pumps

Impellers, Containment Shells, Glide Bearings, and Shafts—Engineered to Your Requirements

Bij GFT9 zijn we toonaangevende experts in PFA-bekleding, gespecialiseerd in de productie van PFA-beklede kleppen, filters en op maat gemaakte onderdelen. Maar onze expertise gaat verder. Door PFA-injectie met precisieproductie te combineren, leveren we een breed scala aan PFA-beklede reserveonderdelen voor pompen.

Ons assortiment omvat schoepen, glijlagers, containment mantels, en pompas die allemaal compatibel zijn met de veelgebruikte Richter MNK magneetpompen. Via reverse engineering, ontwikkeld in samenwerking met een klant, hebben we onze expertise in deze onderdelen verder uitgebreid. Onze ervaring met het bouwen van PFA-beklede pompen heeft de basis gelegd voor een snelle en nauwkeurige productie van deze essentiële pompcomponenten. We kijken er ook naar uit om in 2025 onze eigen GFT-pompreeks te lanceren—neem contact met ons op voor meer informatie.

We manufacture reverse-engineered spare parts for PFA-lined magnetic drive pumps. Our experience includes components compatible with MNK-type, SCK-type, and similar ISO/DIN standard pump designs.

  • Schoepen:

    Ontworpen voor een soepele en efficiënte vloeistofoverdracht, waardoor het risico op cavitatie en slijtage wordt verminderd. Onze PFA-beklede schoepen zijn bestand tegen chemische corrosie en bieden verbeterde duurzaamheid in toepassingen met hoge druk.

  • Glijlagers:

    Deze lagers ondersteunen de pompas en zorgen voor een soepele rotatie. Ontworpen om hoge belastingen te weerstaan en wrijving te verminderen, zijn onze lagers bijzonder gevoelig voor slijtage in schurende omgevingen, waardoor ze een essentieel reserveonderdeel zijn.

    View Glide Bearings Range 

  • Containment Mantels:

    Werken als een barrière om lekvrije werking te garanderen, en zijn van cruciaal belang in magneetpompen. Onze mantels zijn ontworpen voor een hoge drukbestendigheid en chemische weerstand, waardoor lekkages worden voorkomen, zelfs onder extreme omstandigheden.

    View Containment Shell Range 

  • Pompas:

    De pompas zorgt voor een correcte koppeloverdracht zonder mechanische afdichtingen. Gemaakt met hoog-precisieproductie, zijn onze PFA-beklede pompas ontworpen om bestand te zijn tegen chemische blootstelling en zorgen voor een juiste uitlijning, zelfs in uitdagende operationele omstandigheden.

Wear and Tear in Magnetic Drive Pumps

Chemical pumps, especially magnetic drive pumps (mag drive pumps) are vital for industries handling corrosive chemicals and high-temperature applications. These pumps use magnetic coupling to eliminate the need for seals, reducing leakage risks. However, wear and tear can significantly affect their lifespan, especially when lined with PFA for chemical protection. Frequent wear occurs in critical components such as impellers, glide bearings, containment shells, and shafts.

Key Reasons for Wear:

Running dry: This can cause the impeller and glide bearings to overheat, leading to expansion and permanent damage.

Solid particulates: Abrasive particles within the fluid can erode containment shells and glide bearings, causing degradation over time.

Permeation: Over time, certain aggressive substances can diffuse through the PFA lining, particularly under high temperatures and pressures, leading to degradation of the underlying metal components such as containment shells.

Thermal cycling: Repeated exposure to extreme temperature changes causes material fatigue, leading to micro-cracks and eventual failure of parts like containment shells and shafts.

Compatible with Leading Magnetic Drive Pump Designs

GFT9 has reverse-engineered spare parts for pumps originally manufactured to ISO/DIN standards by major European suppliers. Our experience includes:

MNK-Type Magnetic Drive Pumps:

These heavy-duty lined mag-drive pumps are widely installed in chemical plants handling corrosive acids, chlor-alkali processes, and high-purity applications. We manufacture compatible:
• Impellers (closed design with back vanes)
• Double containment shell systems (PTFE inner shell, CFK outer shell)
• SSiC glide bearing assemblies
• PFA-lined shafts and rotors

SCK-Type Side Channel Pumps:

Self-priming designs for applications requiring suction lift. We manufacture compatible impellers and containment components.

Block Pump Configurations (MNK-B type):

Close-coupled designs with shared bearing assemblies. Our parts are manufactured to original face-to-face dimensions for direct replacement.

Als u voor uw reserveonderdelen voor GFT9 kiest, vervangt u niet alleen versleten onderdelen—u investeert in superieure kwaliteit, verbeterd ontwerp en langdurige prestaties. Onze klanten willen vaak de afhankelijkheid van OEM-reserveonderdelen doorbreken vanwege hoge prijzen of leveringsproblemen. Bij GFT9 hebben we kosteneffectieve en technisch geavanceerde alternatieven geboden, met de volgende voordelen:

Faster Delivery, Better Value

When you choose GFT9 for your spare parts, you aren’t just replacing worn-out components—you’re investing in superior quality, enhanced design, and longer-lasting performance. Our clients often seek to break free from the constraints of OEM spare parts due to high prices or availability issues. At GFT9, we’ve provided cost-effective and technically advanced alternatives, offering the following benefits.

Standard Lead Time:

Typical OEM: 10-20 weeks | GFT9 3-5 weeks

Emergency Delivery:

Typical OEM: Often unavailable | GFT9 1-2 weeks (established parts)

Minimum Order:

Typical OEM: Often required | GFT9: Single pieces welcome

Pricing:

Typical OEM: Premium | GFT9: 30-50% savings typical

Customization

Typical OEM: Limited vs. GFT9 Standard practice

Support:

Typical OEM: Distributor-level | GFT9: Direct engineering access

Our lead time advantage comes from in-house manufacturing. Once we've created tooling for your specific part, repeat orders move quickly through our production system. Many customers establish blanket orders with safety stock held at our facility for immediate dispatch.

For completely new parts requiring tooling development, initial lead times are longer—typically 6-8 weeks including engineering and mold production. Subsequent orders then benefit from the faster standard lead times.

FAQ

  • Q: Are your parts truly compatible with brand-name pumps?

    A: Yes. We reverse engineer from actual pump components or OEM specifications to ensure dimensional compatibility. Many of our customers have been using GFT9 spare parts as replacements for years without issues. That said, we recommend that customers with critical applications discuss their specific requirements with our engineering team before first orders.

  • Q: What information do you need to quote spare parts?

    A: Ideally, the OEM part number or pump model designation. If those aren't available, send us:
    • Physical dimensions (we can work from your measurements)
    • Photos of the existing part• Pump nameplate information
    • Operating conditions (chemical, temperature, pressure)

  • Q: Can you improve on the original design?

    A: Often, yes. Our reverse engineering process includes failure analysis. If your parts are wearing prematurely, we can recommend material upgrades, geometry modifications, or surface treatments to extend service life. This is one of the key advantages of working with an engineering-focused supplier rather than a distributor.

  • Q: What about warranty on aftermarket parts?

    A: GFT9 provides warranty coverage for manufacturing defects. Our parts are inspected and tested before shipment. We also maintain traceability records for material certification when required.

  • Q: Can you integrate with our procurement systems?

    A: Yes. We work with several customers on blanket order arrangements, consignment stock programs, and electronic procurement integration. Our goal is to make reordering as seamless as possible for your maintenance team.
