Multi-Purpose Filtration
The MPF filter series helps to prevent contamination problems by effectively removing suspended solids from process water from coarse particles down to very low levels (~1 mg/litre or 1 ppm).
![Upstream Pumping](/-/media/j/johncrane_com/images/events/2022/weftec-2022/upstream-pumping-404.png)
Upstream Pumping
Tackle high heat Generation, low-lubricity, and intermittent dry-running conditions.

John Crane Diamond®
Derived from nature’s hardest substance, John Crane Diamond uses ultrananocrystalline diamond (John Crane Diamond®) treatment—a thin film of genuine diamond that is grown via chemical vapor deposition on the seal face.
