Titanium and Titanium Alloy Pumps
Titanium and Titanium Alloy Centrifugal Pumps are designed for aggressive chemical and corrosive service conditions where reliable performance, strong corrosion resistance, and long service life are essential. Available in horizontal or vertical configurations, these pumps support a wide operating range, with DN 25–400 mm sizes, flow rates up to 2400 m³/h, head up to 300 m, working pressure up to 2.5 MPa, and operating temperatures from -80°C to +450°C. Depending on the medium and corrosion severity, key wetted parts such as the impeller, casing, cover, shaft sleeve, and shaft can be manufactured from titanium grades including TA2 / Grade 2, TC4 / Ti-6Al-4V, TA9 / Ti-0.2Pd, and TA10 / Ti-0.3Mo-0.8Ni, making these pumps well suited for acids, alkalis, salt solutions, seawater, organic chemicals, and other demanding industrial media.
