DESCRIPTION |
Product description：
The CDLF+CDH series is a dual-pump high-pressure system capable of delivering up to 70 bar. It consists of:
CDLF: Feed pump (booster stage)
CDH: High-pressure pump (reverse rotation design)
The unique counter-rotating flow path ensures the pressure vessel and mechanical seal only withstand the feed pump's outlet pressure, enhancing reliability.
Key Features：
✔ 46-70 Bar High Pressure Output
✔ Energy-Efficient Motor (IE3/IE4 standards)
✔ Compact & Lightweight Vertical multistage design
✔ Easy-Maintenance Split-type mechanical seal
Performance Curve (ISO 9906:2012 Grade 3B)
Tested at 2900/2950 rpm with 20°C water (1 mm²/s viscosity)
Operate within bold curve range to avoid:
Overheating (low flow)
Motor overload (high flow)
Technical Specifications
Liquid Temp:
Standard: -15°C to +70°C
Hot Water: -15°C to +120°C
Ambient Temp: ≤+40°C
