1.5/1B-AH Slurry Pump: Complete Specifications, Performance Curve & Applications

When it comes to handling abrasive slurries in small-scale operations, laboratory testing, or pilot plants, size and precision matter. The 1.5/1B-AH is the compact powerhouse of the renowned Warman AH series, designed to deliver reliable performance where space is limited but durability cannot be compromised.

At Hebei XingOu Machinery Equipment Co., Ltd., we manufacture genuine-compatible 1.5/1B-AH slurry pumps that meet and exceed original equipment standards. Whether you need a replacement for an existing unit or a new pump for a specific low-flow application, this guide provides everything you need to know about this versatile model.

What is the 1.5/1B-AH?

The model number 1.5/1B-AH breaks down as follows:

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

• 1: Suction diameter of 1 inch (25 mm).

• B: Frame size code, indicating a medium-duty bearing assembly suitable for various drive arrangements.

• AH: Represents the Heavy Duty Slurry Pump series design, featuring a robust casing and interchangeable wet end parts.

This pump is specifically engineered for low flow rate and high head applications, making it the industry standard for mineral processing labs, sample testing, and small-scale dredging projects.

Key Technical Specifications

Before selecting a pump, understanding its physical and operational limits is crucial. Here are the standard specifications for the XingOu 1.5/1B-AH:

Performance Curve: 1.5/1B-AH

Understanding the hydraulic performance is vital for system design. The 1.5/1B-AH offers a wide operating range through different impeller diameters and rotational speeds. It is capable of generating significant head pressure despite its compact size, making it ideal for lifting slurry to higher elevations or overcoming long pipeline resistance.

The pump efficiency peaks in the mid-range of its curve, ensuring energy-efficient operation when sized correctly.

How to Read the Curve:

• Head (Y-axis): The maximum height the pump can push the slurry. The 1.5/1B-AH can reach up to ~58m at zero flow.

• Flow (X-axis): The volume of slurry moved per hour. Optimal efficiency is usually found between 4–10 m³/h.

• Impeller Trim: By machining (trimming) the impeller diameter, you can fine-tune the pump to match your exact system requirements, saving energy and reducing wear.

Ideal Applications for the 1.5/1B-AH

Due to its size and hydraulic characteristics, the 1.5/1B-AH is the go-to choice for:

1. Laboratory & Pilot Plants: Perfect for metallurgical testing, density separation trials, and small-batch processing where precise flow control is needed.

2. Sample Transfer: Moving slurry samples from sampling points to analysis tanks in mining operations.

3. Small-Scale Mining: Used in artisanal or small-scale gold/copper operations where large pumps are overkill.

4. Chemical Processing: Handling abrasive chemical slurries in smaller production lines.

5. Filter Press Feed: Often used as a feed pump for small laboratory filter presses due to its ability to generate higher pressures.
