When Wichita Clutch needed a diaphragm for a new brake actuator to withstand increased temperatures of up to 200degC, they turned to sealing specialists Ceetak
Wichita Clutch is a leading manufacturer of tension braking systems for the paper converting industry.
When they needed a diaphragm for a new brake actuator to withstand increased temperatures of up to 200 deg C, while increasing the stroke requirement all within a fixed operating area in a harsh environment, they turned to sealing specialists Ceetak.
Design parameters were stringent, with the diaphragm needing a wide-ranging stroke capability and fast accurate response to pressure and temperature changes.
Ceetak designed a rolling diaphragm in Flourosilicone with Nomex reinforcement for strength and maximum temperature resistance.
A special internal bead maximised the space available allowing the increased stroke capacity.
Ceetak diaphragms have completed in excess of 20,000 cycles under life tests in the harsh conditions described which now allows Wichita's brake actuator to stay ahead of the competition with outstanding performance.
