Ordering
Add the four digit prefix “151B” to the four digit numbers from the chart for complete code number.
Example:
151B3002 for an OMT 250 with standard flange, cyl. 40 mm shaft and port size G 3/4.
Orders will not be accepted without the four digit prefix.
Technical data
Maximum permissible shaft seal pressure
Motor with check valves and without use of drain connection
The pressure on the shaft seal never exceeds the pressure in the return line.
151-320.10
Motor with check valves and with drain connection
The shaft seal pressure equals the pressure on the drain line.
OMT FX, OMT FL and OMT FH must always be fitted with drain line.
Maximum pressure in drain line is 5 bar [75 psi]
