C.R.I. MV Series pumps
C.R.I. MV Series pumps
The C.R.I. MV Series pumps are state-of-the-art vertical multistage inline centrifugal pumps, engineered for high-pressure applications where space efficiency and reliable performance are paramount. Building on C.R.I.'s extensive experience, these pumps are meticulously designed with inline suction and discharge ports at the same level, simplifying pipework and offering significant space savings compared to traditional horizontal pumps.
These non-self-priming pumps are distinguished by their high-quality construction, featuring corrosion-resistant stainless steel (SS 304/SS 316) impellers, shafts, and stage casings as standard, ensuring durability and hygienic operation, even with aggressive fluids. The design prioritizes enhanced hydraulic efficiency, resulting in optimal flow and head performance across a wide range of applications.
Powered by a totally enclosed fan-cooled (TEFC) motor, MV Series pumps are designed for continuous duty (S1) and are available in both single-phase (with thermal protection) and three-phase versions. Maintenance is made easy with a strengthened cartridge mechanical seal that can often be replaced without disassembling the entire pump from the system. With low noise and vibration levels, C.R.I. MV Series pumps are a reliable and environmentally friendly solution for various industrial, commercial, and domestic pressure boosting needs.
