Why Choose YOUNAI Slurry Pumps
The design of YOUNAl slurry pumps is based on the most advanced theoretical research. We utilize Creo 3.0 for 3Dhydraulic modeling and flow passage optimization of key components like the impeller, volute, and extension sections at the suction and discharge. Further refinement with CF-turbo software reduces hydraulic loss for smoother flow and higher efficiency. Finally, CFD simulations analyze complex internal solid-liquid two-phase flows and provide predicted performance parameters for various solid concentrations.
State-of-the-art composite material technology that solves the challenges of corrosion and abrasion—vacuum‑cast silicon carbide ceramic lining. This composite material handles any environment from pH 1 to 14. Performance is unaffected by chlorides or fluorides in the slurry.
YOUNAl translates advanced design into durable reality through state-of-the-art manufacturing. Our workshop houses precision CNC lathes, GOODWAY mill-turn centers, and massive 5-meter gantry mills for large components. Pump shafts are finished on TSUGAMl automated lines for unmatched consistency.
Our high-quality slurry pumps are supported by a rigorous quality management system with strict process controls. Every critical component is inspected and approved to design specifications using a HEXAGON coordinate measuring machine and 3D laser scanner. Each spare part is assigned a unique code for full traceability and easy replacement.
Every slurry pump undergoes performance testing to ensure it meets your required capacity, head, and temperature parameters.
Customer Testimonials
In our mineral processing plant, we faced severe abrasion challenges with slurry containing 10-12mm particles (20% content) at 40% weight concentration, including broken steel balls at ambient temperature. The previous metal pumps lasted only about 60 days. After upgrading to YOUNAI silicon carbide ceramic heavy-duty slurry pumps, service life now exceeds 14 months.
Reza KhanChief Engineer, Iran Mineral Processing Plant, IranIn our iron-molybdenum ore beneficiation process, the slurry medium has a maximum particle size of 10–13mm (10% content), a median particle size of 5mm, a weight concentration of 55–60%, and a pH of 8.4. The original metal pump had a service life of only about 2 days. After replacing it with the YOUNAI silicon carbide ceramic heavy-duty slurry pump, the service life reached 24 days, which is 12 times that of the original metal pump.

In our best-selling slurry pump series, the maximum solid particle diameter is 92mm. In mining, they typically process slurry solids ranging from 11mm to 88mm. Should you have any specific requirements, please contact us. Our slurry pumps can be customized and tailored to meet them.
With decades of slurry pump manufacturing experience, YOUNAI offers metal slurry pumps in industry-standard materials, including cast iron (ASTM A48 CL 35 B), chromium iron (ASTM A532 IIIA, Gx100CrMo30-2), and high-chrome alloy. For optimal performance and extended lifespan, we highly recommend our ceramic slurry pumps.
For standard slurry pump models, the typical lead time is 4 weeks. YOUNAI maintains a well-stocked inventory of semi-finished components, which enables shorter delivery time.
For ceramic slurry pumps, the common materials for wetted parts include various silicon carbide ceramics, such as: Silicon Carbide Ceramics, Resin-Bonded Silicon Carbide (SiC), Silicon Nitride-Bonded Silicon Carbide Composite (Si₃N₄-SiC), Reaction-Bonded Silicon Carbide (RB-SiC), Recrystallized Silicon Carbide (R-SiC), Pressureless Sintered Silicon Carbide (SSiC).
The primary measure is selecting materials suited to the operating conditions, such as chrome iron, high-chrome alloys, and silicon carbide ceramic composites. Superior materials ensure outstanding resistance to abrasion, corrosion, and high temperatures in harsh environments. Next, the YOUNAI slurry pump impeller is designed with front and rear expeller vanes, which reduce wear at the suction inlet and help extend mechanical seal life. Finally, a large-diameter, short-overhang pump shaft reduces bending under load. All these features combine to deliver a significantly longer lifespan.
Absolutely. Our slurry pumps can be custom-engineered to meet your specific parameters for capacity, pressure, temperature, solids, PH, viscosity.
A slurry pump is a type of centrifugal pump specifically designed to handle fluids containing a high concentration of solid particles, with wear-resistant performance. Its operating principle is also centrifugal. The commonly referred-to centrifugal pump is primarily used for pumping clean water or fluids with low solid content.
