1) Los valores son aplicables:
- At an abs. pressure pabdominales = 1 bar at the suction port S
- for the optimum viscosity range from Velegir = 36 a 16 mm2/s
- with hydraulic fluid on the basis of mineral oils
2)See diagram on page 9 at speed increase up to nmax adm.
3)The data are valid for values between the minimum required and maximum permissible rotational speed. It applies for external stimuli (e.g. diesel engine 2 to 8 times rotary frequency, cardan shaft twice the rotary frequency). The limit value is only valid fora single pump. The load capacity of the connection parts must be considered.
