What may seem like a straightforward pump application can often demand far more expertise than anticipated. Take, for example, this G13 Hydra-Cell multi-diaphragm pump from Wanner International that is going to be pumping slightly salty water at 400 l/hr. At first glance, this might not appear to be a particularly challenging task.

However, the requirements for this application make the selection process more complex. Since the water is used in a hygienic application, a stainless-steel pump is essential. Additionally, the flow rate must be precise and accurately controlled, necessitating a positive displacement, pulse-free pump. Finally, with a discharge pressure of around 70 bar, the G13 stands out as the ideal solution.
