ICN - ISO Chemical process pump

ISO Process Pump for clear, viscous, fibrous and sticky liquids


Centrifugal ISO Process Pump complying with ISO2858‐5199 standard

- Closed or semi-open impellers provide high efficiency over a wide performance range while maintaining low NPSHr.- Flanges PN16 - Option PN20 ANSI (150 lbs).
- Metal-to-Metal casing seal providing the right O-Ring compression and a perfect alignment.
- Tapered seal chamber with ribs to reduce circumferential velocities, solids and gas pockets.
- Grooved wear ring to prevent seizing risks.
- Closed or semi-open impellers provide high efficiency over a wide performance range while maintaining low NPSHr.
- Wear plate is sealed by O-ring.
- The design allows for easy installation and removal of the impeller while providing a strong reliable power transmission (double that of keyed impeller design). It is self-locking and tolerates reverse rotation.
- Shaft sealing by mechanical seal (cartridge seal or component) and various optional sealing constructions.
- Bearing frame has a large oil capacity to provide optimum bearing lubrication.
- Adjustable bearing carrier allows for easy impeller clearance adjustment to the wear plate.
- Standard shaft material is duplex stainless steel, which provides both high mechanical strength and superior corrosion resistance.
- Standard bearing protection by Inpro or equivalent oil seals.
- Back-to-Back angular contact bearings handle both high hydraulic axial loads and radial loads due to belt drives.
- High radial load roller bearing.
