Connecting SvP 7030 hydraulically

The machine or system manufacturer is responsible for dimensioning the lines.
The Sytronix system must be connected to the rest of the hydraulic system
in accordance with the hydraulic circuit diagram of the machine or system
manufacturer.
Notes on the routing of lines and the optimum installation
Please observe the following notes on the routing of suction, pressure and case
drain lines:
● See to it that the suction line (pipe or flexible hose) is as short and straight
● The line cross-section of the suction line is to be dimensioned so that the
● Observe air tightness of the junctions and pressure resistance of the flexible
● In conjunction with the pressure lines, make certain that the pipes, flexible
● Always route case drain lines so that the housing is constantly filled with
The ports and mounting threads are rated for the operating pressures specified
in the data sheet. The machine or system manufacturer must ensure that the
connecting elements and lines comply with the specified operating conditions
(pressure, flow, hydraulic fluid, temperature) with the necessary safety factors.

Hydraulic pipes and hoses installed under stress!
NOTICE
Hydraulic pipes and flexible hoses which are installed
under mechanical stress generate additional mechanical
forces during operation, which reduces the service life
of the Sytronix system and the machine or system as a
whole.
−
Install pipes and flexible hoses stress-relieved.
Insufficient suction pressure!
NOTICE
Risk of damage! Generally, a minimum permissible suc-
tion pressure at port "S" is prescribed for Sytronix sys-
tems in all installation orientations. The permissible min-
imum suction pressure can be found in the data sheet of
the pump. If the pressure at port "S" drops below the
specified values, damage may occur which may lead to
the destruction of the Sytronix system.

Make sure that the required suction pressure is ach-
ieved. This is influenced by:

during extended standstill periods. Under no operating conditions may the
pressure inside the case exceed the limit values specified for the Sytronix
system. The case drain line in the tank must in any case terminate below the
minimum fluid level.
