Efficient, Cost-effective Products
As demand for fresh water grows and natural resources become increasingly limited, managing costs can be difficult — even more so for plants in remote or elevated locations. Strict environmental standards for disposing waste or managing runoff can also present additional obstacles. John Crane offers a wide range of innovative solutions that increase process efficiency while lowering costs, such as our mechanical seal support systems that are engineered to reduce contamination and our mechanical seals that require little to no external flush water. As a global leader in the design, manufacture and supply of components with proven reliability in seawater pumps, flushing pumps, transfer pumps, booster pumps and intake pumps.
Cost-saving Technology
By reducing water usage, John Crane’s SmartFlow intelligent seal water support system lowers the amount of water used to lubricate mechanical seal faces, resulting in reduced water and filtration costs. Our modular seals—like the Type 5600 series and heavy-duty Type SB series—can be standardised across entire facilities for efficiency. The Type 37FS split seal enables quick replacement without dismantling large equipment like pulpers, agitators and fan pumps.
