Technical Data Shaft seal ring			Temperature range
Permissible  pressure  load			The FKM shaft seal ring is permissible for case temperatures of -25°℃ to +115°C.
The service lifte of the shaft seal ring is affected by the speed of the motor and the case drain pressure.It is recommended that the average,continuous case drein pressure at operating temperature 3 bar absolute not be exceeded (max.permissible case drain pressure 6 bar absolute at reduced apeed,see dia- gram).Short  term(t<0.1  s)pressures  spikes  of  up  to  10  bar absalute are permitted.The service life of the shaft seal ring de- creases with an increase in the frequency of pressures spikes. The case pressure must be equal to or greater than the extemal pressure on the shaft seal ring.			Note:
			For application  cases  below-25°C,an  NBR shaft seal  ring  is necessary  (permissible  temperature  range:-40°℃ to  +90°C). Please state NBR shaft seal ring in plain text when ordering. Please  cantact  us.
			Effect of case pressure on start of control An increase in the case pressure has an effect on the following controls when control of the variable motor begins:
			HA1T(sizes  28  to  160)				__	increase
			HD,ER,HA,HA.T(size		250)			increase
							__
			DA_          _				decrease
			The start of control is set in the factory at a case pressure of Pata=2  bar  (sizes  28  to  160)and  Pa=1  bar  (eize  250).

Caution:     Exceeding the permissible limit values may result in a loss of function,a reduction in service lfe or in the                  destruction of the axial piston unit.
	Other permissible limit values with respect to speed variation,reduced angular acceleration as a function of the fre-       quency and the permissible startup angular acceleration (lower than the maximum angular acceleration)can be found       in data sheet RE 90261.
