Why is the ALH Pump the Perfect Carbon Slurry Pump?

banner-carbon-slurry.png

When it comes to moving carbon slurries, you’re dealing with one of the toughest challenges in fluid handling.

The mix of rough particles, thick liquids, and chemical additives can quickly damage mechanical seals. It can also clog impellers and lead to expensive downtime. That’s why picking the right carbon slurry pump is very important. The Albin Pump ALH series is designed to handle this challenge directly

What Is Carbon Slurry in Water Treatment?

In water treatment, carbon slurry is a mix of activated carbon and water. Sometimes, other chemicals are added. Activated carbon is used to remove impurities, organic compounds, chlorine, and odors from water.

Carbon slurry is made by mixing powdered or granular activated carbon with water. This mixture is used for dosing into filters, contact tanks, or adsorption systems.

It appears at multiple stages:

  • Slurry preparation: Carbon is blended with water to create a pumpable mix.
  • Dosing or injection: The slurry is transferred to filters, clarifiers, or tanks.
  • Backwash and recirculation: Used carbon is often removed, re-slurried, and either disposed of or reactivated.

Handling carbon slurry safely and efficiently is very important. The abrasive carbon particles can wear out pumps quickly. They can also settle in pipelines and disrupt consistent dosing. That’s why a strong carbon slurry pump, like the ALH hose pump, is essential in water treatment facilities.

The Challenge of Pumping Carbon Slurries

Carbon slurries - whether in water treatment, mining, or chemical processes - are notoriously abrasive. The fine yet sharp carbon particles can erode metal components, while the slurry’s density and viscosity increase energy demand and wear.

Common issues with traditional pump types include:

  • Rapid seal and impeller wear in centrifugal pumps
  • Frequent clogging in diaphragm pumps when solids settle
  • High maintenance costs from replacing multiple internal parts
  • Shear damage to sensitive or coated carbon particles

For a truly reliable carbon slurry system, you need a pump that can handle solids, minimize wear, and offer predictable flow without constant maintenance.

The ALH Hose Pump: Built for Abrasive and Viscous Media

The Albin Pump ALH is a heavy-duty peristaltic hose pump. Instead of relying on seals, impellers, or valves, it works by compressing a reinforced hose to move the fluid forward. Only the hose and the slurry ever make contact: which immediately eliminates the most common failure points in abrasive applications.

Key Advantages for Carbon Slurry Applications

  • Superior Abrasion Resistance
  • Handles High Solid Content
  • A seal-less design that protects against leaks
  • Self-Priming and Dry-Running Capability
  • Low Shear, Gentle Pumping
  • Handles Viscosity and Pressure with Ease
  • Reversible Flow for Cleaning and Flushing

 

Where ALH Pumps Outperform Conventional Slurry Pumps

Pump Type Common Issue with Carbon Slurry ALH Advantage 
CentrifugalHigh wear on seals and impellersNo seals or impellers exposed to slurry
DiaphragmValves clog with solidsNo valves; full-bore hose design
Progressive CavityExpensive maintenance, sensitive statorEasy hose replacement, lower lifecycle cost
Gear / RotaryPoor solids handlingHandles large particles and high solids easily

When durability and uptime matter, the Albin Pump ALH stands out as one of the most reliable options for carbon slurry pumping. Its hose-only contact design minimizes wear, its self-priming capability simplifies operation, and its reversible, low-shear pumping action makes it ideal for abrasive or viscous carbon slurries. 

If you’re specifying a carbon slurry pump for your water treatment or industrial process, the ALH series deserves a spot at the top of your list.
