Advanced Desalination & Reverse Osmosis Pump Features
|
Superior Anti-Corrosion Constructed with SS316L, Duplex 2205, and Super Duplex 2507 stainless steel to resist harsh chloride and saline pitting corrosion. |
High System Efficiency Optimized hydraulic design delivers maximum pressure output with reduced power consumption for low total cost of operation. |
Continuous High Pressure Capable of generating up to 80+ bar discharge pressure essential for high-flux membrane separation in SWRO operations. |
Engineered Structural Integrity for SWRO & RO Membranes
Designed specifically for industrial water treatment and desalination processing, FILIPUSI vertical multistage pumps ensure uninterrupted fluid delivery across membrane filtration networks.
| • | Heavy-Duty Wetted Parts: Impellers, diffusers, and shaft sleeves are precision machined from high-grade stainless steel alloys for extended operation. |
| • | Specialized Mechanical Seals: Equipped with corrosion and wear-resistant silicon carbide (SiC/SiC) mechanical seals tailored for high-salinity fluids. |
| • | Low NPSH Hydraulic Design: Minimizes cavitation risk and acoustic vibration under varying inlet pressure conditions. |
| • | Modular Vertical Footprint: Inline connection configuration saves plant floor space and simplifies maintenance without pipe dismantling. |
