John Crane's new coupling.
John Crane's new coupling.

The ZMH from John Crane is corrosion resistant and can withstand the hot, humid and hostile environments typically found in cooling towers. The coupling has no wearing parts, requires no lubrication and features a composite fibre spacer piece making it up to 80% lighter than alternative 'all metal' designs. The coupler incorporates a stainless steel radial spoke membrane.
