In modern water and wastewater treatment, chemical dosing has evolved far beyond simple proportional control. With tighter discharge regulations, rising chemical costs, and increasingly complex treatment processes, operators now need systems that deliver high accuracy, fast response, and long-term stability—even under demanding high-pressure conditions.
This is exactly where the High Pressure CENTRAC Metering Pump stands out. By combining advanced mechanical design with intelligent electronic control, it offers a more precise and reliable solution for today’s dosing challenges.
Why High-Pressure Metering Pumps Matter
Metering pumps play a critical role in dosing chemicals such as:
- Coagulants
- Disinfectants
- pH adjusters
- Corrosion inhibitors
In pressurized systems, even small dosing errors can lead to:
- Inefficient chemical consumption
- Fluctuating treatment performance
- Process instability
- Higher operating costs
Traditional metering pumps often struggle to maintain accuracy when flow rates and pressures change. The CENTRAC design takes a different approach to overcome these limitations.
What Makes CENTRAC Different?
Constant Stroke Length Technology
At the heart of the CENTRAC pump is its constant stroke length mechanism. Unlike conventional pumps that adjust stroke length to control flow, CENTRAC pumps keep the stroke length fixed and regulate output through an electronic variable speed drive.
Why This Matters:
- Consistent volume per stroke
- Linear and predictable flow behavior
- Reduced mechanical wear
This design enables ±0.5% accuracy across the full operating range, outperforming the typical ±1% accuracy of traditional pumps.
In practical terms, this means better process control and less chemical waste—especially in applications where precision is critical.
Fast Response with Electronic Variable Speed Control
CENTRAC pumps use an electronic variable speed drive to adjust flow instantly. This is particularly valuable in environments where:
- Influent flow rates fluctuate
- Water quality changes rapidly
- Dosing requirements vary in real time
Key Advantages:
- Immediate adjustment without mechanical lag
- Smooth performance at both low and high flow rates
- Stable operation under changing pressure conditions
For operators, this translates into consistent dosing even in dynamic treatment scenarios.
Wide Operating Flexibility: 100:1 Turndown Ratio
One of the standout features of the High Pressure CENTRAC Metering Pump is its 100:1 turndown ratio.
What This Means:
- One pump can handle a wide range of flow demands
- Reduced need for multiple pump models
- Simplified system design and spare parts management
This is especially useful in water treatment plants where demand varies significantly between peak and off-peak periods.
Ideal for Water & Wastewater Applications
CENTRAC pumps are designed to excel in a variety of treatment processes, including:
- Coagulation and flocculation dosing
- Disinfection and oxidation
- pH adjustment and alkalinity control
- Nutrient removal
Their ability to maintain precise dosing under pressure makes them suitable for both municipal and industrial facilities.
Real Cost Savings Through Precision
Accuracy isn’t just a technical specification—it directly impacts operating costs.
With consistent ±0.5% dosing accuracy, CENTRAC pumps help:
- Prevent chemical overdosing
- Improve treatment consistency
- Reduce sludge production
- Lower overall chemical consumption
Over time, these benefits can result in significant cost savings, particularly in large-scale or continuous operations.
Built for Reliability in High-Pressure Environments
High-pressure systems can quickly wear down traditional pump components. CENTRAC pumps are engineered for durability, offering:
- Simplified mechanical structure
- Smooth, low-vibration operation
- Long service life with minimal wear
This translates into fewer breakdowns, less maintenance, and improved operational uptime.
Easy Integration with Modern Control Systems
Automation is a key part of modern treatment plants, and CENTRAC pumps are built with integration in mind.
