- Reliable operation with water temperatures up to approx. 60°C
- Low power consumption relative to the pressure they deliver
CK vs. CKR – What’s the Difference?
While both models perform similarly, the main difference is:
CK
- Standard peripheral pump
- Best for stable water sources where air doesn’t enter the system
CKR
- Equipped with a built-in venturi system
- Better at handling situations where air or gas may mix with the water
- Ideal for applications where suction conditions aren’t perfect
Why Choose Pedrollo CK/CKR Series
- Reliable in long-term daily use
- High pressure output despite small size
- Cost-effective solution for household and light commercial needs
- Easy installation and maintenance
- Strong and durable mechanical design
- Performs well even when water supply is weak
