3/2C-AH Slurry Pump: Complete Specifications, Performance Curve & Heavy Duty Applications

When standard medium-duty pumps aren't enough, operations require the extra robustness of the C-Frame design. The 3/2C-AH is a heavy-duty powerhouse in the Warman AH series, featuring the same 3-inch discharge and 2-inch suction as its "B" counterpart, but equipped with a significantly larger Type C bearing assembly. This allows it to handle higher horsepower, greater radial loads, and more demanding continuous duties.

At Hebei XingOu Machinery Equipment Co., Ltd., we engineer our 3/2C-AH slurry pumps to withstand the rigors of high-energy grinding circuits and long-distance transport. If your application demands reliability under high stress, this guide details why the 3/2C-AH is the superior choice.

What is the 3/2C-AH?

The model designation 3/2C-AH highlights its heavy-duty configuration:

• 3: Discharge diameter of 3 inches (80 mm).

• 2: Suction diameter of 2 inches (50 mm).

• C: Frame size code. This is the critical differentiator. The "C" frame features a larger, heavier-duty bearing assembly compared to the "B" frame, designed to support higher shaft loads and transmit power from larger motors (up to ~45kW/60HP).

• AH: Represents the Heavy Duty Slurry Pump series, known for its thick-walled casing and versatile wet end materials.

The 3/2C-AH is specifically chosen for applications where the duty point requires higher power input or where the slurry conditions impose significant radial forces on the shaft, ensuring longer bearing life and reduced maintenance.

Key Technical Specifications

The upgrade to the "C" frame unlocks higher performance capabilities. Here are the standard specifications for the XingOu 3/2C-AH:

Performance Curve: 3/2C-AH

While the hydraulic end (volute and impeller options) shares similarities with the 3/2B-AH, the 3/2C-AH is rated to operate at higher powers and potentially higher speeds without compromising bearing life. This makes it ideal for duty points that sit at the upper limit of the "B" frame's capability.

The performance curve offers a wide operating range with excellent efficiency, capable of maintaining high head pressures even when pumping high-density slurries.

Why the "C" Frame Matters in Performance:

• Higher Power Capacity: Can safely drive larger impellers or run at higher speeds with motors up to 45kW, whereas the B-frame is typically limited to lower power ranges.

• Extended Bearing Life: The larger bearings in the C-frame absorb greater radial and axial loads, significantly extending Mean Time Between Failures (MTBF) in harsh, high-vibration environments.

• Operational Flexibility: Allows operators to run the pump closer to its maximum hydraulic potential without risking mechanical failure.

Ideal Applications for the 3/2C-AH

The 3/2C-AH is the go-to solution for demanding industrial scenarios:

1. High-Density Cyclone Feed: Perfect for feeding large hydrocyclone batteries where high pressure and flow stability are critical for classification efficiency.

2. SAG/Ball Mill Discharge: Handles the heavy, coarse slurry discharge from primary grinding mills where shock loads and abrasion are extreme.

3. Long-Distance Tailings Transport: Its robust construction supports the higher head requirements needed for pumping tailings over longer distances or to elevated storage.

4. Coarse Coal & DMS: Ideal for Dense Media Separation circuits handling heavy magnetite/ferrosilicon slurries.

5. High-Solids Concentration: Excellently suited for pumping slurries with very high solid concentrations (>60% by weight) which impose significant load on the pump shaft.
