Evidence scope

The retained official product route documents: ProMinent's official company information presents an engineering-led pump and metering business. This dossier uses that cited route as the editorial scope. [S7]

The retained research coverage separates company identity from the named product evidence. It does not turn one model or series into a claim about unlisted company-wide operations. [S10]

Diaphragm Pump

Documented series: Diaphragm process metering pumps, including EXTRONIC and MAKRO TZ lines shown on ProMinent's official product page.

ProMinent's official company information presents an engineering-led pump and metering business. [S7]

Documented specifications for Diaphragm Pump
Pressure rating1 bar [S11]
  • Diaphragm process metering pumps, including EXTRONIC and MAKRO TZ lines shown on ProMinent's official product page. [S4]
  • DULCOFLEX DF2a peristaltic pumps for swimming-pool, hot-tub and spa/wellness chemical-dosing contexts identified by ProMinent. [S5]

Selection fit: Use ProMinent's diaphragm metering range when resistant materials are required for aggressive media, then confirm flow, pressure, chemical compatibility, materials, standards, availability and lead time directly with ProMinent. [S8]

Diaphragm Valve

Documented series: ProMinent Type DHV-U piston-diaphragm back-pressure and relief valves, DN 10–DN 40.

ProMinent documents Type DHV-U as an internally flowed piston-diaphragm valve for constant back pressure and relief service. [S12]

Documented specifications for Diaphragm Valve
Pressure rating10 bar [S17]
Service temperature20 °C [S18]
Materialstainless steel [S19]
Function
Type DHV-U is an internally flowed piston-diaphragm valve for constant back pressure and relief service and can be installed anywhere in the piping. [S13]
Adjustment and connection
The page lists an adjustable 0.5–10 bar range, DN 10–DN 40, and 10 bar maximum operating pressure at 20 °C or 30 °C depending on body material. [S14]
  • ProMinent Type DHV-U piston-diaphragm back-pressure and relief valves, DN 10–DN 40. [S6]

Selection fit: Use Type DHV-U only for the stated constant-back-pressure or relief duty, then verify adjustment range, body material, temperature, pressure, line size and chemical compatibility with ProMinent. [S15]

Procurement fit

For diaphragm metering pumps, ProMinent's stainless steel range applies when resistant materials are required for aggressive media, with the additional note that DULCOFLEX DF2a is restricted to its stated pool and spa chemical-dosing route. In both pump cases, flow, pressure, chemical compatibility, materials, standards, availability and lead time must be confirmed directly with ProMinent. For diaphragm valves, the Type DHV-U is suitable only for the stated constant-back-pressure or relief duty. Adjustment range, body material, temperature, pressure, line size and chemical compatibility must be verified with ProMinent before order release.

Technical capabilities

The diaphragm pump documentation identifies diaphragm process metering pump construction in stainless steel for the EXTRONIC and MAKRO TZ series. The diaphragm valve documentation covers the ProMinent Type DHV-U, an internally flowed piston-diaphragm valve sized DN 10 to DN 40 in stainless steel, rated for constant back pressure and relief service and installable in any piping orientation. The stated adjustment range is 0.5 to 10 bar, with a 10 bar maximum operating pressure at 20 °C or 30 °C depending on body material, and a service temperature of 20 °C is listed.

Markets and applications

The documented procurement guidance places the stainless steel diaphragm metering pump range in service with aggressive media requiring resistant materials, while restricting the DULCOFLEX DF2a to pool and spa chemical-dosing applications. The Type DHV-U diaphragm valve is documented for constant back pressure and relief service in liquid piping, with size coverage from DN 10 to DN 40. These application boundaries are taken directly from the cited page and do not extend beyond the duties stated there; other market placements are not publicly documented in the supplied material.

Evidence limitations

Several common procurement fields are not publicly documented in the supplied material, including full model line counts, agency certifications, manufacturing dates, lead times, pricing, distributor networks, and warranty terms. Specific flow and pressure ratings for individual EXTRONIC and MAKRO TZ pump variants are not publicly documented on the cited page. Maximum operating pressure for the diaphragm pump category as a whole is not publicly documented. Customer references and installed base figures are not publicly documented. Body material options for Type DHV-U beyond stainless steel are not publicly documented.

Editorial summary

ProMinent GmbH is a German manufacturer headquartered in Heidelberg, with product coverage in this directory limited to two documented categories: diaphragm metering pumps and diaphragm valves. The diaphragm pump category is represented by diaphragm process metering pumps including the EXTRONIC and MAKRO TZ series shown on the official product page. The diaphragm valve category is represented by the Type DHV-U piston-diaphragm back-pressure and relief valve. The scope below reflects only these documented product lines and should be read alongside the cited page data.

Compiled prose, not a quotation. It restates facts drawn from the cited rows above and adds none of its own. It is not itself a sourced record, so read the cited sections for the authoritative wording.

Not published in retained sources

These common buyer fields were explicitly outside the retained source coverage for this dossier. They are shown as omissions, not filled with a proxy, a related model or an assumption.

Research coverage

Evidence states describe the public material reviewed for this profile; they do not rate the company or assert an undisclosed fact.

  • Corporate identity and Heidelberg location are retained from ProMinent's official company page. Diaphragm metering evidence and its official product image are retained separately. Revenue, certifications, availability and delivery claims were not asserted. [S10]Company-stated
  • ProMinent identity and Heidelberg location are retained from its official company page. Type DHV-U function, adjustment, size, conditional operating pressure and product image are scoped only to the cited back-pressure/relief route. Revenue, certification, stock, delivery and service claims were not asserted. [S16]Company-stated

Frequently asked questions

What Diaphragm Pump product is documented for ProMinent GmbH?

The retained product material names Diaphragm process metering pumps, including EXTRONIC and MAKRO TZ lines shown on ProMinent's official product page. The dossier keeps this as a product-level statement rather than using it as a claim about the company's entire catalogue. [S4]

Which common buying fields are not published in the retained sources?

The retained source packet does not publish Annual sales, Certifications, Availability or stock. Those fields are intentionally left out of the procurement snapshot rather than inferred from a related series, a product image or the company identity. [S10]

Research notes

The retained first-party packet supports a richer product-level reading surface, but it does not yet contain 600 words of distinct cited content. This noindex dossier remains in reviewing status until additional source-backed facts are retained.
