How a Swedish Roof Tile Producer Reduced Air Consumption, Noise, and Pulsation
What Pump Is Used for Adding Color in Roof Tile Manufacturing?
The largest roof tile manufacturer in Sweden uses air-operated diaphragm pumps to transfer coloring agents and additives into the concrete mix. These additives include iron oxide pigments for red coloration and carbon black to improve thermal conductivity and tile strength.
To improve efficiency and product consistency, the manufacturer replaced its existing pumps with 2” Pivot Series diaphragm pumps from SAMOA Industrial.
What Was the Application Challenge?
In concrete roof tile production, coloring agents must be delivered smoothly and consistently. The manufacturer faced several operational issues with its existing diaphragm pumps:
Key Challenges
- Excessive pulsation and vibration, affecting color consistency
- High compressed air consumption, increasing energy costs
- Elevated noise levels, impacting the working environment
The goal was to improve process stability while reducing energy usage and operational strain.
What Pump Solution Was Selected?
After evaluating the application requirements, the local distributor recommended a 2” SAMOA Pivot Series diaphragm pump, specifically:
- Model: UP20A-BAC-HHC
- Material: Aluminium construction
- Elastomers: Hytrel balls and diaphragms
This configuration was selected to handle abrasive pigment mixtures while delivering smoother and more efficient flow.
How Does the SAMOA Pivot Series Improve Pump Performance?
Frictionless Pivot Shaft Air Valve
The SAMOA Pivot Series features an innovative frictionless pivot shaft air valve, designed to deliver:
- Smoother, more uniform flow
- Significantly reduced pulsation and vibration
- Faster air valve changeover for improved efficiency
This design directly improves the stability of the coloring process and reduces mechanical stress on the system.
Lower Air Consumption
The fast-shifting air valve minimizes wasted compressed air, allowing the manufacturer to lower overall air consumption and improve energy efficiency in the coloring stage.
Reduced Noise Levels
The pump’s short, oversized exhaust air passages eliminate whistling and air restriction noise. This results in quieter operation and a more comfortable production environment.
Why Was the SAMOA UP20 Diaphragm Pump a Success?
The switch to SAMOA Pivot Series diaphragm pumps delivered measurable improvements:
Results Achieved
- Noticeably lower sound levels during pigment transfer
- Significant reduction in pulsation and vibration
- Improved coloring consistency in roof tiles
- Reduced compressed air consumption and energy costs
The customer benefited from a more stable, efficient, and quieter coloring process—without compromising performance or reliability.
What Are the Key Benefits of SAMOA Diaphragm Pumps in Construction Materials Manufacturing?
- Smooth, low-pulsation flow for consistent product quality
- Energy-efficient operation with reduced air usage
- Quiet performance suited for continuous industrial environments
- Durable construction for abrasive pigment and additive handling
Final Takeaway
For roof tile manufacturers handling pigment-rich and abrasive fluids, SAMOA Pivot Series UP20 diaphragm pumps provide a proven solution that improves process control, reduces operating costs, and enhances workplace conditions.
