Road Saw Applications

Wet Cutting with Oberdorfer Centrifugal Pumps

Road saws (also known as concrete saws or floor saws) are powerful machines used to cut through hard surfaces such as asphalt, concrete, and stone. These machines are commonly used in construction, road maintenance, and utility installation.

The Role of Water in Road Sawing

During cutting, the blade generates intense heat due to friction. If not properly cooled, this can:

  • Damage the blade (causing warping or cracking),
  • Reduce cutting efficiency,
  • Create hazardous dust (especially when cutting concrete).

To address these issues, wet cutting is used—where water is continuously applied to the blade during operation.

How Oberdorfer Pumps Support Wet Cutting

Oberdorfer centrifugal pumps are integrated into road saw systems to deliver a steady flow of water directly to the cutting blade. These pumps are known for their durability, compact design, and consistent performance, making them ideal for mobile and rugged applications like road sawing.

Key Features of Oberdorfer Pumps in This Application:

  1. Centrifugal Design
    1. Efficient at moving large volumes of water at low to moderate pressure.
    2. Ideal for continuous flow applications like blade cooling.
  2. Corrosion-Resistant Materials
    1. Often made from bronze or stainless steel to withstand dirty water and abrasive particles.
  3. Compact and Lightweight
    1. Easily integrated into portable road saw units without adding excessive bulk or weight.
  4. Reliable Operation in Harsh Conditions
    1. Designed to handle vibration, dust, and temperature fluctuations typical on construction sites.

Benefits of Using Oberdorfer Pumps in Road Saws

  • Prolongs Blade Life: Keeps the blade cool and reduces wear.
  • Improves Safety: Minimizes airborne dust, which can be harmful to operators.
  • Enhances Cutting Performance: Maintains optimal blade temperature for smoother, faster cuts.
  • Reduces Maintenance: Prevents overheating-related damage to both the blade and the saw.

Typical Use Cases

  • Highway and road construction: Cutting expansion joints or removing damaged pavement.
  • Utility trenching: Creating access paths for pipes or cables.
  • Airport runway maintenance: Precision cutting of concrete slabs.
  • Industrial flooring: Cutting through reinforced concrete in warehouses or factories.
