The series of slurry pump in hydraulic design, structure design and innovation, over-current components using the self-developed erosion resistance of the high chromium wear-resistant alloy cast iron manufacturing, with high efficiency, energy saving, long service life, light weight, reasonable structure, reliable operation, small vibration, low noise, maintenance is convenient wait for a notable feature. The pump body adopts a double pump shell structure, convenient replacement parts; according to the pressure to pump shell with nodular cast iron and grey cast iron, pump shell with high chromium white cast iron or cast steel.
