ZJ slurry pump of high efficiency, energy saving, wear-resisting products, according to the principle of minimum loss design, easy selection, vibration light, low noise. This series of pump flow components using high hardness alloy hybrid material, high abrasion resistance, impact resistance, so as to increase the service life. The pump delivery of the largest concentrations: mortar 45%, 60% of the pulp. Drive form can use direct coupling, belts, hydraulic, frequency control of motor speed and so on, also may in series or parallel. Shaft seal form mainly pay impeller and packing and mechanical seal two. Pump head structure for double hull vertical open, outlet position according to 45 degrees of interval rotating eight different position installation and use.
