2/1.5B-AH Slurry Pump: Complete Specifications, Performance Curve & Applications

Stepping up from the compact lab models, the 2/1.5B-AH represents the entry point into medium-duty industrial slurry handling. As a core member of the legendary Warman AH series, this pump strikes an optimal balance between flow capacity and head pressure, making it a workhorse for small-to-medium mining operations, coal washing plants, and general industrial slurry transfer.

At Hebei XingOu Machinery Equipment Co., Ltd., we engineer our 2/1.5B-AH slurry pumps with precision casting and superior metallurgy to ensure they withstand the harshest abrasive environments. Whether you are upgrading an old unit or designing a new process line, this guide details everything you need to know about this versatile model.

What is the 2/1.5B-AH?

The designation 2/1.5B-AH provides immediate insight into its configuration:

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

• 1.5: Suction diameter of 1.5 inches (40 mm).

• B: Frame size code, utilizing the robust "B" frame bearing assembly designed for moderate loads and versatile drive options (belt or direct drive).

• AH: Signifies the Heavy Duty Slurry Pump architecture, known for its thick-walled casing and interchangeable wet end components.

This model is widely recognized for its ability to handle higher volumes than the 1.5/1B-AH while maintaining excellent head capabilities, making it ideal for continuous duty cycles in processing plants.

Key Technical Specifications

Proper sizing is critical for pump longevity. Below are the standard operational parameters for the XingOu 2/1.5B-AH:

Performance Curve: 2/1.5B-AH

The hydraulic profile of the 2/1.5B-AH is designed for versatility. It offers a broad range of operating points, allowing it to adapt to varying pipeline lengths and elevation changes. Its curve demonstrates a stable head characteristic, which is essential for preventing surging in systems with fluctuating slurry densities.

The pump achieves peak efficiency in the mid-to-high flow range, ensuring cost-effective operation when moving significant volumes of abrasive material.

How to Interpret the Data:

• Head Capability: With a maximum head approaching ~56m, this pump can effectively push slurry over moderate distances or lift it to secondary processing stages.

• Flow Capacity: Capable of moving up to 27 m³/h, it is suitable for main circulation loops in smaller plants or feed lines for larger classifiers.

• Impeller Selection: The wide selection of impeller diameters allows for precise matching to your system curve, minimizing energy waste and reducing wear rates on the liner and impeller.

Ideal Applications for the 2/1.5B-AH

The 2/1.5B-AH is a favorite among plant engineers for its reliability in diverse scenarios:

1. Coal Washing Plants: Widely used for transferring coal slurries and dense media separation (DMS) circuits due to its ability to handle high-density mixtures.

2. Tailings Transfer: Ideal for moving tailings from cyclones to thickeners or small tailings dams in medium-scale operations.

3. Mineral Processing Circuits: Perfect for mill discharge, sump pumping, and feeding hydrocyclones in gold, copper, and iron ore plants.

4. Sand & Gravel Dredging: Used on smaller dredges for pumping sand and gravel slurries to shore or processing screens.

5. General Industrial Slurry: Handling abrasive waste streams in power plants (ash slurry) and chemical manufacturing.

Why Choose XingOu for Your 2/1.5B-AH?

While the 2/1.5B-AH design is an industry standard, XingOu Machinery elevates the performance through superior manufacturing practices:
