EnglishWhat Is GemmeCotti and What Does gemmecotti.com Offer?
Updated
GemmeCotti is an Italian manufacturer of chemical pumps for acids, aggressive and corrosive liquids, and gemmecotti.com is its product and company website. According to the site, the company has been designing and manufacturing these pumps since 1992, uses components from Italian suppliers, and supports customers through selection, customization, and quotation requests. The site is aimed at industrial and OEM buyers who need to move or transfer chemicals safely, rather than at household or consumer use.
What the site presents
The homepage positions GemmeCotti around "safe and reliable industrial pumps" and a complete range for acid and corrosive liquids. It lists the main pump families with headline performance figures, which is the quickest way to see whether a product type matches your duty point.
| Pump family | Max flow (Q) | Max head / pressure |
|---|---|---|
| Mag drive centrifugal pumps | 130 m³/h | 48 mlc |
| Mag drive turbine pumps | 9 m³/h | 50 mlc |
| Mag drive rotary vane pumps | 2,100 l/h | 13 bar |
| Self-priming mag drive pumps | 25 m³/h | 22 mlc |
| Mechanical seal pumps | 130 m³/h | 48 mlc |
| ATEX pumps | 130 m³/h | 48 mlc |
| Vertical pumps | 130 m³/h | 48 mlc |
| Air-operated double diaphragm pumps | 310 l/h | 80 mlc |
| Portable pumps | 13 m³/h | 14 mlc |
The site also lists mixers (electric and pneumatic), drum pumps, self-priming dosing pumps, and accessories. These figures are the manufacturer's published maxima; a specific model's curve still needs to be checked against your actual flow and head.
How the pump types differ in practice
The families are not interchangeable, and the distinction matters when you are choosing:
- Mag drive (sealless) pumps — centrifugal, turbine, vane, and self-priming variants — avoid a mechanical shaft seal, which is the usual leak path with aggressive fluids. The trade-off is that mag drive couplings can lose drive if run dry or overloaded, so dry-run protection and correct sizing matter.
- Mechanical seal pumps reach the same 130 m³/h and 48 mlc envelope as the mag drive centrifugal line, so seal type becomes a decision about fluid, maintenance access, and site practice rather than capacity.
- ATEX pumps are the variant to look at when the installation is in a classified hazardous area; the site lists them as a separate family with the same performance envelope.
- Vertical pumps suit sump or tank-mounted duties where the pump sits in or over the liquid.
- Air-operated double diaphragm pumps are driven by compressed air rather than a motor, which is relevant where compressed air is available and electrics are not desirable at the pump.
- Rotary vane pumps reach much higher pressure (13 bar) at lower flow, which points to dosing or transfer duties rather than bulk circulation.
For example, transferring acid from a road tanker into a storage tank at high flow is a different job from circulating a small volume in a PCB line at pressure — the first points toward a centrifugal or vertical pump in m³/h, the second toward a vane pump rated in bar.
Applications the site names
GemmeCotti states its pumps are used wherever chemicals, acids, dangerous and corrosive liquids must be handled or transferred, and lists these sectors: chemical industry, galvanic industry, PCB industries, water treatment, air treatment, detergents, biofuel, loading/unloading tanks, oil & gas, food industry, bottling companies, pharmaceutical industry, aquariums, fertilizer production, textile industry, and refrigeration systems for data centers. The site also emphasizes customization for industrial and OEM processes.
Use this list as a relevance check, not a compatibility guarantee: a named industry tells you the pump family has been applied there, but the wetted materials still have to be matched to your specific fluid and concentration.
What you can do on the site
The site is structured as a product catalog plus a sales channel. You can browse the complete range by pump family, review the headline performance figures, and use a "Request a quote" action to start a commercial conversation. The site describes specialized assistance throughout the purchase process, and customization is offered for industrial applications.
Practical steps if you are evaluating a pump:
- Note your fluid, concentration, temperature, and whether the area is ATEX-classified.
- Note your required flow and head (or pressure) at the duty point.
- Shortlist the pump families whose published maxima cover your duty point with margin.
- Request a quote with those figures so the manufacturer can confirm the model and wetted materials.
What the site does not tell you
The available page content does not publish prices, lead times, warranty terms, or certification details beyond the existence of an ATEX pump line. The only commercial signal on the page is a subscribe option and the quote request. Treat pricing and availability as things to confirm through the quote process rather than assumptions from the site.
If your question is simply "what is this company," the answer is a long-established Italian chemical pump manufacturer with a broad sealless and sealed pump range and a quote-based sales model. If your question is "which pump do I need," the site gives you the families and their envelopes, but the selection decision still runs through fluid compatibility and a confirmed duty point.
