AHF froth pump, a horizontal heavy froth duty slurry pump, is designed for pumping stubborn-froth slurry. With inducer blade impeller design, it's for heavy froth and viscous concentrated non-Newtonian slurries in mining (flotation, thickening, tailings), with unique designs for harsh conditions.
Unique Design Features and Benefits
Unique Impeller and Inlet Design
AHF froth pumps are equipped with a large, oversized inlet and a unique impeller inducer blade. This design allows the pumps to handle heavy froth and higher-viscosity dense slurries with ease.
lThe large inlet reduces inlet velocities and lowers the Net Positive Suction Head Required (NPSHr).
lThe inducer blade pre-swirls and smoothes the flow as the slurry enters the pump.
lThe impeller has oversized inducer blades on each vane and a large eye, which dissipates or reduces the size of entrained air bubbles, preventing them from inhibiting slurry flow.
lThe impeller comes in abrasive-resistant types, such as high-chrome metal or rubber, or a mixed assembly. This ensures long-lasting performance even when dealing with abrasive froth slurries.
lContinuous Air Removal System (CARS): This upgrade effectively separates and removes air from tenacious froth. It mitigates the performance impacts of aerated slurry and eliminates air-locking at the impeller eye.
Robust Construction
lHeavy-duty construction with a through-bolt design provides ease of maintenance and minimal downtime. The ductile iron fully lined casing offers durability, strength, safety, and a long service life.
lLarge diameter, slow-turning, high-efficiency impellers are designed to achieve maximum wear life and low operating costs. The large, open internal passages reduce internal velocities, further maximizing wear life and lowering operating costs.
Advanced Sealing and Bearing Systems
lCartridge-style bearing assemblies allow for maintenance in a clean environment without removing the pump. This results in reliable operation and prolonged bearing life. In addition, full-flush, low-flow or dry-running centrifugal seals minimize water usage and operating costs.
Enhanced Head Handling
lCapable of handling a higher total head, ensuring efficient transport of challenging slurries.
Superior Froth and Viscous Slurry Handling
lAHF Horizontal Froth Pumps are highly effective in handling the air-binding issues that plague standard pumps when dealing with froth. The froth inducer blade impeller solves this problem, leading to far less surging, smaller pump selections, and higher efficiencies. They can handle viscous slurries with ease, as the main problem of getting the slurry into the pump is addressed by their design.
lCompared to other pumps in similar applications, AHF froth pumps are less likely to experience bearing and shaft failures, especially when compared to vertical froth pumps.
Long-lasting and Cost-effective
lAHF Horizontal Froth Pumps offer long wear and service life. With options like thick R55 rubber and high-chrome A05 alloy bolt-in liners, they provide superior erosion and corrosion resistance. The minimal shaft/impeller overhang reduces shaft deflection and increases bearing life.
lAHF Horizontal Froth Pumps have a low total cost of ownership. For example, large inlet diameter impellers are designed for maximum wear life, and full-flush, low-flow or dry-running centrifugal seal options minimize water usage and operating costs.
Applications
Mining & Minerals Processing Industry
Horizontal froth pumps are extensively used in the mining & minerals processing industry, especially in the flotation circuit of mineral processing plants. They help in separating minerals from waste in flotation cells by pumping the froth and viscous slurries. They are also used for concentrate thickener feed and underflow, tenacious regrind cyclone feed, and tailings filtration.
They can handle a wide range of minerals such as copper, molybdenum, iron, gold, diamonds, and many others as follows.

Other Industries
AHF Horizontal Froth Pumps can be used in sugar cane refining and wood saw milling processes. In addition, they are suitable for applications where froth or paste-like slurry needs to be pumped for further dewatering to produce the final product.
Product Specifications
Size Range (Discharge)：50mm to 550mm (2” to 26”).
Head / Pressure: Heads up to 65m (213ft) / Pressure up to 305psi (2,100kPa),
Flow Rates (capacity): Up to 35,000 USgpm (8,000m3/h).
Materials Available: Froth consists of extremely fine particles. Rubber liners are highly resistant to this kind of wear, demonstrating remarkable cost-effectiveness. For our AHF froth pump series, we provide either rubber or metal liners. The rubber liners are available in R55 natural rubber, and for slurries containing hydrocarbons or reagents, synthetic rubber options are offered. Additionally, if needed, high-chrome A05 white iron can be used, and the outer casing is made of ductile iron.
