We offer unique, highly specialized NP and NPC on-metallic pump models, which represent an optimal solution for your UPW production plant. Ovivo by Ecolab UPW pumps have the following features:
- Superior quality materials (PVDF-HP, SiC, E-CTFE) for maximum purity
- All wetted parts are cleaned according to semiconductor-grade requirements
- Peak performances with large range of flow and pressure
- Designed for cold and hot processes and suitable for a large range of temperatures from -20 to 110 C (-4 to 230 F)
- Increased lifetime and maintenance-friendly with simple assembly and disassembly High purity metal-free materials
All pumps periodically require maintenance, which needs to be followed by a rinse up before being returned to operation. However, during rinse up, standard pumps often shed particles that must be flushed at high velocities – a process in itself that can result in particles contaminating the distribution system. While particles cannot be removed completely, conductive particles from standard pumps can be eliminated from the process stream by replacing 316L Stainless Steel impellers with PVDF-HP impellers, which is one of the main features of Ovivo’s UPW pumps. Any particles, should they exist, will therefore be inert, minimizing the conductive device failure that might result during pump maintenance, possible leaks or pump failure.
Our mechanical seals (stationary and rotating seal rings), specifically developed for our non-metallic pumps, are made from Silicon Carbide (SiC). In addition, the spring is coated with a fluoropolymer. Together, these provide superior corrosion and wear resistance, ensuring maximum operating reliability and a long service life while being easy to assemble, disassemble and repair.
