    Equipment for the Chemical Industry

    Corrosive fluids in the chemical industry call for materials such as PVDF, PFA or titanium, chosen according to the concentration of the acid or base and the operating temperature, to avoid premature corrosion of the equipment. We quote sealless magnetic pumps, PVDF/PP pumps, PFA ball valves, titanium exchangers and sensors for corrosive media. Send the safety data sheet (SDS) of the fluid and the operating temperature so we can select the right material.

    Frequently asked questions

    Which material do I choose for a pump handling concentrated acids or bases?

    The choice depends on the fluid and concentration: PVDF and polypropylene (PP) resist most acids and bases well at moderate temperatures and are cheaper than special metals, but have temperature and pressure limits. For very concentrated acids or ultra-pure fluids, PFA (a processable form of PTFE) offers almost universal chemical resistance. If the fluid is hazardous and you cannot afford any leak (for example liquid chlorine or toxic acids), the magnetic pump, with no shaft seal, reduces the risk of leakage through the seal. Send us the safety data sheet (SDS) of the fluid and the operating temperature.

    When do I choose a magnetic pump instead of one with a conventional mechanical seal?

    The magnetic pump transmits rotation through a magnetic coupling, with no shaft passing through the casing, so there is no seal that can wear out or fail - reduced risk of leakage through the seal. It is a suitable choice for toxic, flammable, highly corrosive or hard-to-dispose-of fluids, where a leak means a high cleaning cost or an environmental report. The drawback: higher sensitivity to dry running (without fluid), which can burn the bearings, so the system must be protected with a level or minimum flow sensor. For clean fluids without large abrasive particles, it is a suitable long-term solution.

    Which valve withstands concentrated acids and ultra-pure fluids?

    Ball valves with a PFA lining offer very wide chemical resistance (comparable to PTFE, but mechanically stiffer) and are the standard option for concentrated acids, ultra-pure products or applications where any contamination from the valve would affect the quality of the final product. The metal body (carbon steel or stainless steel, depending on the external environment) provides mechanical strength, while the PFA lining contacts the fluid. For solvent media at high temperature, check the temperature limits of PFA (usually up to about 150°C) against the real process temperature, so that you do not choose a thermally undersized solution.

    Why choose a titanium heat exchanger for a chemical process?

    Titanium resists corrosion very well in media with chlorides, seawater or strong oxidising solutions, where conventional stainless steel (even duplex) would suffer pitting corrosion over time. The initial investment is higher than for stainless steel, but the longer service life in suitable media recovers the cost difference in the long run, especially if shutdowns for replacement mean lost production. It is not a universal solution, however - for strong reducing acids (for example concentrated hydrochloric acid) titanium can corrode rapidly, and other materials are more suitable there. We analyse compatibility from the chemical data sheet of the fluid.

    What information do you need for a quote on chemically resistant equipment?

    The most important item is the fluid's safety data sheet (SDS), with the exact concentration, operating temperature, line pressure and any suspended solid particles. If you already know what equipment you use now and what problem you have (premature corrosion, leaks, rapid wear), tell us - changing a single material (for example from standard stainless steel to duplex or PVDF) often solves the problem without replacing all the equipment. For parts, the lead time is 24–72 h when the item is available locally or at the supplier, and for equipment in special materials made to order (titanium, special alloys), usually 1–4 weeks; it may take longer depending on the brand and the specifications.
