Wastewater and Clean Water Management

Use our new estimator tool to calculate your water and CO2 emissions savings

The high volumes and abrasiveness associated with wastewater and clean water management pose a significant challenge when it comes to designing the supporting equipment. Because the ratio of water to abrasive material from a single source can change frequently, every component has to be durable enough to withstand extreme abrasiveness and still perform reliably. That’s where John Crane comes in. Our products provide cost-effective solutions that reduce energy consumption and increase the efficiency of equipment used in all types of clean water and wastewater applications, from filtration to chlorination.

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. And strict environmental standards for disposing waste or managing runoff can present additional obstacles. Fortunately, John Crane offers a wide range of innovative solutions that increase process efficiency while lowering costs, such as our John Crane seal support systems that are engineered to reduce contamination and our seals that require little to no external flush water. We’re a world leader in the design, manufacture and supply of components with proven reliability in seawater pumps, flushing pumps, transfer pumps, booster pumps and intake pumps.
