Watson-Marlow Bredel  supplied SPX40 hose pumps to a Brazilian mining company for pumping sulphuric acid at high temperatures.

Votorantim Metais, a zinc and nickel mining company in Brazil tried a range of pumps for a challenging application involving the pumping of 3m³/hr of 98.5% sulphuric acid at temperatures from 85ºC to 100ºC, running 10 hours per day.

The company had tried AODD, progressive cavity, lobe and centrifugal pumps that barely lasted a day before requiring maintenance. Their centrifugal pump in fact, lasted just 10 hours.

Watson-Marlow Bredel’s sales manager in Brazil, Helbert Fontoura declined to supply their pumps because the hose life would not be satisfactory under the given temperature range. On the customer’s insistence, Watson-Marlow Bredel supplied an SPX40 pump on trial with a Hypalon hose. The hose lasted three days, which was long enough for the customer to issue a purchase order for an SPX40.

Watson-Marlow Bredel shipped the pump with an EDPM hose, which lasted five days. The customer was extremely satisfied with the pump’s performance, given that he had to conduct maintenance only once a week.
