Instrumentation, pumps and separation for water and wastewater plants
A treatment works has no shut-down, so a probe that fails twice in eighteen months is not a reorder — it is a wrong variant you keep paying for. On shukchok six housings stand side by side, two of them without a hazardous-area version, at the position rather than on the telephone.
Your pump sump
Buying the same probe twice is a repeat, not a decision
Eighteen months, and it stands still again. You can order the identical probe and already know the outcome — or you can change the variant. For the second option you need housing material, measuring range, output signal and hazardous-area availability side by side.
That is normally the moment you ring the manufacturer, wait for a field visit and receive a quotation your finance office sees the week after next. The shaft keeps working in the meantime, and so does the corrosion in it.
Here the variant logic is readable at the article, with the net price beside it. A quotation with its own number, date and validity date sits as a PDF in the customer account — the document a procurement file asks for.
- Six housing variants on one probe, hazardous-area availability stated per variant
- Purchase order number and cost centre run through to the invoice and onto the budget line
- Quotation with number, date and validity as a PDF in the account
The variant decides
Six housings — and where the choice closes a door
The submersible probe P133 is offered in six housings. Two of them are expressly excluded from the hazardous-area version, which turns chemical resistance and zone suitability into an either/or.
| Variant | Housing / connection | Hazardous-area version |
|---|---|---|
| Type 1 | Stainless 1.4404, Ø 40 mm | available |
| Type G | Stainless 1.4404, G ½ A with 11.8 mm bore | available |
| Type GL | Stainless 1.4539 (904L), G ½ A with 11.8 mm bore | available |
| Type R / Type 6 | 1.4404, Ø 40 mm, Serto fitting or G ½" at the cable outlet | available |
| Type 2 | Polypropylene | expressly not available |
| Type P | PVDF | expressly not available |
What one ordering process changes
Four corners of the market, one basket
A treatment works rarely needs only a probe. Pump, float switch, microwave limit switch and separator otherwise come from four corners of the market, with four quotations and four invoice runs. On shukchok — an open marketplace for industrial goods — those four corners share one basket and one ordering process.
And the measuring range is the second question to ask before changing supplier. Accuracy is quoted as better than ± 0.2 % of full scale; in a sump working between 10 and 40 % of the range, the real error at the working point is a multiple of that.
So you size the range for where the level actually sits, not for the highest figure in the design documents. With both numbers side by side that decision takes minutes instead of a round of enquiries.
- Pump, switch and probe in one ordering process instead of four
- 904L housing for chloride and hydrogen sulphide, 1.4404 as the standard
- Limit switch FM1 explicitly insensitive to foam and build-up
- housing variants on one submersible probe
- 6
- Two of them expressly without a hazardous-area version — from the article description, 8 August 2026
- articles with a structured specification table
- 114 of 114
- Catalogue as counted on 8 August 2026
- sensors in the catalogue, plus four pressure sensors
- 13
- Level, pressure, temperature and proximity
- accuracy of full scale on the P133
- ± 0.2 %
- The P135K is quoted at ≤ 0.3 % — compare at your working point, not on the headline figure
For manufacturers and distributors
Your customers run exactly these shafts
Anyone building aerators, penstocks, screens, probes or pumps for the water industry can read the first half of this page as a market description: municipal operators who replace parts while the plant runs, and a procurement route that needs a document for the file. Those operators already order here.
Shelf space costs you no fee, neither once nor monthly. We earn on the margin of a position that sells, and on nothing before that. Your prices, your dimensions and your papers stay with you; shop, checkout and customer contact stay with us.
And where this catalogue is thin today, the marketplace has room: pH, redox, dissolved oxygen and turbidity measurement, magnetic-inductive flow meters, gas detection instruments. Whoever carries them hangs them in and delivers through the same basket.
- Listing without a basic charge, without a term and without waiting for a release
- You maintain your article data yourself and you set your own prices
- Checkout, invoicing and payment handling run through us
