Heavy-Duty PFA Bellows | Imperium9 Control Valve | GFT9
Heavy-Duty PTFE/PFA Bellows Assembly for GFT9 Imperium9 control valves. The bellows seal is the heart of bellows-sealed control valves—providing hermetic st...

Solutions · Spare parts
Spare parts for our own valves and strainers — and a clear route to replacement parts for equipment of other makes.
Our spare parts come in two groups. Spare parts for GFT9 products — strainer baskets, PTFE parts, seat rings and lined valve parts — are made to the drawings of our own valves and strainers. For equipment of other makes, we start from your part: you send it, we measure and document it, and we manufacture the replacement.
Parts are made to order, also in small batches; where your demand can be planned, we can keep parts in stock for you. Strainer baskets can be ordered in the shop. For a part that is no longer available, see our reverse-engineered solutions — we are open for requests.
Which product for which duty
| Duty | Product |
|---|---|
| Bellows, seats or plugs of an Imperium9 control valve | Control valve spare parts |
| Replacement basket for a GFT9 T-strainer | PTFE strainer basket |
| Basket where electrostatic charge must be led off | Antistatic strainer basket |
| A worn or soon-to-be-replaced part of a pump or strainer of another make | Send the part → measured and documented → manufactured |
| A part that is no longer available | Reverse-engineered solutions |

Send us the worn or soon-to-be-replaced part. We measure it, document the geometry and materials, and keep the record on file — the basis for your equivalence approval later. Then we manufacture the replacement: strainer baskets, lined impellers, SSiC shafts, bearings and bushes, containment shells and other lined or machined parts. Ask for your pump or strainer type.

Why GFT9
Planning and design, machining, PFA lining and testing are done in one house in Germany — from the drawing to the finished part.
We measure your part, document the geometry and materials, keep the record on file and build the replacement to the same fit and function.
With the part we supply equivalence documentation, gauges and first-article records, so that your own qualification of the replacement part runs smoothly.
Parts are made to order, also in small batches. Where your demand can be planned, we can keep parts in stock for you.
Spare part ranges
PFA-lined impellers, SSiC shafts, glide bearings and bushes, and containment shells, made to order. Select the parts and request a quote.

Strainer baskets in PTFE and in an antistatic version for GFT9 T-strainers. The basket is pulled from the top, so the strainer stays in the line. For a strainer of another make, send us the installed basket.
For a part that is no longer available: we measure the original part, redraw it and build it to the same fit and function — the lined impeller is our model case. With documentation for your own qualification of the replacement part. Open for requests.

FAQ
Pump spare parts are made to order, also in small batches. Where your demand can be planned, we can keep parts in stock for you. Select the parts in the shop, send the request, and we respond with an individual offer. Strainer baskets can be ordered in the shop.
Send us the worn or soon-to-be-replaced part. We measure it, document the geometry and materials, keep the record on file and manufacture the replacement. Ask for your pump type.
Baskets come in PTFE and in an antistatic version. If you are not sure which one fits your strainer and medium, tell us both and we confirm the choice.
Send us the installed basket, or tell us the strainer type and size and the medium. We measure and document it, and manufacture the replacement to fit your strainer. Ask for your strainer type.
Yes, by reverse engineering. We measure the original part, also by optical scanning and also from heavily worn samples, redraw it and build it to the same fit and function — in PFA, SSiC, steels and composite materials. Dimensional and optical inspection are part of our quality checks.
We support your own qualification of the replacement part: with the part we supply equivalence documentation, gauges and first-article records. The approval itself stays with you.
A sample of the part, and a description of the equipment and the medium, is the starting point. Send what you have and we tell you what else we need.
Send us the equipment, the part and the quantity. We respond with an individual offer.
