Handling HF Acid at 40% volume is a tough job. Achieving a head of close to 24 meters adds to the complexity of the problem. How did we do it ?
Our customer called us down to survey a technical challenge he was facing. The previous system had failed causing a process safety and compliance red flag. The challenge was to deliver a 40% volume solution of Hydrofluoric Acid to a height of 24 meters.
Hydrofluoric acid, chemically written as HF, is used in a wide range of industries, including etching and cleaning processes, chemical manufacturing etc. HF acid, like many other compounds, can have severe and adverse effects on handlers if not used properly. The essence to implement safety checks and quality instruments is essential in such applications. Pumping Hydrofluoric acid has its own challenges and it has to be done effectively.
The only was this could be achieved was by using a DEBEM Sealless Magnetic Drive Pump in PVDF.
Debem’s Magnetic Drive Centrifugal Pump is the ideal solution for numerous applications. The complete lack of metal parts in contact with the fluids being pumped renders them ideal for working with acids and corrosive products.
Debem is a cutting edge company specialised in designing, constructing and producing industrial pumps for highly demanding environments. Debem has been operating in the fluid transfer and movement sector for over 30 years.
The pumps are driven by a pair of magnets: the outer magnet is positioned on the motor shaft and transmits the motion to the inner magnet integrated with the hermetically sealed impeller. The magnetic drive centrifugal pump impeller (closed impeller) is not physically fixed to the motor shaft, thereby eliminating the need for seals and consequently any leaks of the liquid being pumped due to wear. Some of the main applications for these types of pumps are laboratory machines or medical equipment, photographic developing machines, galvanic and chemical industry, water treatment, aquariums, filtering systems, heat exchangers, silver recovery systems, graphics industry and in X-ray processes.
Magnet drive pumps are made with a small number of components, making them very easy to maintain. The pumps are available in Polypropylene (PP) or in Polyvinylidene fluoride (PVDF).

- Constructed in Polypropylene or PVDF
- Under head use
- Extremely easy to maintain
- Suitable for continuous use
The customer witnessed the installation of the pump and also carried out batch trials. Once satisfied he said,
” not only is the pump performing exceptionally well and inline to meet our safety standards, but we find the pump to be relatively silent during operation. The overall experience from understanding the challenge, product selection and execution has left us satisfied. Thank You – Fine Flow Technologies“
