D/DG/MD Multistage Pumps
• Pumping water 0-125℃ or conveying solid particle content (volume concentration) not more than 1.5% (particle size less than 0.5mm), neutral mine water with temperature not higher than 80 ℃ or other similar sewage • The wet parts made of cast iron/cast steel/2Cr13/SS304/SS316 • Inlet：Axial/Vertical • Outlet：Axial/Vertical • Connection method：Coupling or gearbox • The impeller, guide vane and other flow passage components are optimized and designed by CFD flow field analysis technology, with high efficiency; • The static seal between the suction section, the middle section and the discharge section of the pump adopts metal face seal and "O" ring double seal, and the pump shaft seal adopts high-performance ramie Packing or mechanical seal, safe and reliable; • The pump type spectrum is wide, and the large-flow pump is the leading technology in China: • The rotor adopts two balancing processes, static and dynamic, and the rotor runout is strictly controlled, so that the pump operates stably and the vibration is small; • The shaft is made of high-quality carbon steel, alloy steel or stainless steel through multiple heat treatment processes, with high rigidity and good stability; • The unique shoulder positioning structure makes the impeller positioning more reliable and safe;
