Reverse Engineered Spare Parts for PFA-Lined Equipment

Precision-Manufactured Replacement Components for Magnetic Drive Pumps, Valves, and Strainers

Your plant runs on PFA-lined equipment for a reason: nothing else survives the chemicals you handle. But when critical components wear out, you face a difficult choice—wait 12-20 weeks for OEM parts at premium prices, or compromise with inferior alternatives.

GFT9 offers a third option: reverse-engineered spare parts manufactured to your exact requirements. Send us your worn component or drawings, and our engineering team will design and produce a replacement that matches—or exceeds—original specifications.

We've supplied spare parts for magnetic drive pumps, control valves, and strainers to chemical plants, pharmaceutical manufacturers, and process industries across Europe and beyond. Our German manufacturing facility combines PFA transfer molding expertise with precision machining to deliver parts that fit, perform, and last.

How Our Reverse Engineering Process Works

Unlike distributors who simply resell OEM inventory, GFT9 manufactures spare parts in-house using advanced PFA transfer molding and CNC machining. This gives us the flexibility to work from your actual operating conditions—not generic catalog specifications.

Reverse Engineering: Process Steps

Step 1: Consultation

You contact us with your spare parts challenge. Whether it's high OEM prices, unacceptable lead times, or recurring failures, we start by understanding your specific situation.

Step 2: Sample Analysis

Send us your worn or failed component—or provide OEM part numbers and drawings. Our engineers measure critical dimensions, analyze wear patterns, and identify the root cause of failure.

Step 3: Design & Enhancement

We create manufacturing specifications that replicate original functionality while addressing identified weaknesses. Potential improvements include upgraded PFA grades, optimized geometry, and tighter tolerances.

Step 4: Tooling & Production

For new parts, we manufacture dedicated molds and tooling. Once tooling exists, repeat orders ship significantly faster—as quickly as 1-2 weeks for urgent requirements.

Step 5: Quality Verification

Every part undergoes dimensional inspection and material verification before shipment. Documentation including material certificates (EN 10204 3.1) is available on request.

Step 6: Ongoing Partnership

We keep your tooling on file and can integrate with your MRO procurement systems for seamless reordering. Many customers maintain safety stock at our facility for immediate dispatch.

Spare Parts Categories

Our reverse engineering capabilities span the full range of PFA-lined rotating equipment.

This journey began with an order from a customer to design a strainer basket for the Richter GSO Strainer, which had been discontinued from the range. This then became the prototype for our own strainer baskets, which we have been constantly developing and have now been offering as a reliable solution since 2017.

After developing the first pump spare parts compatible with a Richter MNK, we were able to present pump spare parts at Achema 2024 complementing our spare part portfolio.

Below are the main categories—contact us for parts not listed.

  • (Magnetic Drive) Pump Spare Parts

    Impellers, containment shells (Spalttöpfe), glide bearings, shafts, and wear rings for PFA-lined mag-drive pumps. Compatible with systems originally equipped by leading European manufacturers.

Reverse Engineering: Breaking Free from OEM Constraints

Procurement teams across the process industries share similar frustrations with original equipment spare parts:

The OEM Challenge:

• Lead times of 12-20 weeks that don't align with maintenance schedules
• Premium pricing that strains MRO budgets
• Minimum order quantities that force excess inventory
• Limited flexibility for non-standard requirements
• Parts that fail sooner than expected in your specific conditions

The GFT9 Alternative:

• Standard lead time of 4-6 weeks; emergency delivery in 1-2 weeks for established parts
• Pricing typically 30-40% below OEM equivalents
• Single-piece orders welcome—no minimum quantities
• Custom modifications based on your operating experience
• German engineering and manufacturing quality

"We are a pharmaceutical operation looking to optimize our inventory of PFA components. We have Richter and CP Pumpen equipment—impellers, containment shells, that sort of thing. Do you have alternatives?"

When OEM Lead Times Become a Production Problem

A containment shell fails on a critical magnetic drive pump handling hydrochloric acid. The production loop goes offline. The maintenance team submits an urgent spare parts request.

The response from the established supply chain: standard pricing, delivery in 14-16 weeks. Expediting might be possible—at premium cost—but even then, the timeline measures in months, not weeks.

For plants running continuous processes, this arithmetic doesn't work. Extended downtime costs compound daily. Emergency workarounds introduce risk. And the realization sets in: the spare parts strategy that seemed adequate during normal operations becomes a liability when critical components fail.

An Alternative Approach

GFT9 exists precisely for these situations. We manufacture PFA-lined components through reverse engineering—analyzing your existing parts and producing compatible replacements from our German facility.

Typical scenario:

A plant sends us a failed containment shell with the pump model and operating parameters. Within 48 hours, we confirm whether we've manufactured this configuration before (shorter lead time) or need to create new tooling (standard lead time). We provide a formal quotation with pricing typically 30-50% below OEM and delivery in 4-6 weeks for standard orders, faster for repeat configurations.

The part arrives, installs correctly, and returns the pump to service. We retain the tooling and customer specifications for future orders, reducing subsequent lead times to 3-4 weeks.

Building Long-Term Resilience

Many plants that initially contact us during emergencies eventually standardize their spare parts procurement. The economics are straightforward: shorter lead times reduce the inventory required to maintain adequate safety stock, while lower unit costs improve maintenance budgets.

Beyond cost savings, there's operational value in working directly with the manufacturer. When questions arise about material selection, dimensional tolerances, or operating condition optimization, our engineering team engages directly—no distributor intermediaries, no generic technical support queues.

The relationship evolves from emergency supplier to engineering partner.

Equipment We Support

Our reverse engineering experience spans the major European manufacturers of PFA-lined pumps and valves. While we manufacture our own replacement parts—not OEM spares—our engineering team has developed compatibility expertise with:

Magnetic Drive Pumps:

• MNK, SCK, RMA/RMI series magnetic drive pumps
• MKP series from Swiss manufacturers
• Similar ISO/DIN dimensioned lined mag-drive designs

Control Valves:

• Bellows-sealed globe control valves (RSS, HV-type designs)
• GFT9 Imperium9 control valves
• DIN-standard lined control valves

Strainers:

• GSO-type basket strainers
• T-strainer and Y-strainer designs
• DIN-standard lined strainers
