Project planning notes
Project planning notes
▶ The A4VSO ATEX pump is designed to be used in open
circuits.
▶ The project planning, assembly and commissioning
oftheaxial piston unit require theinvolvement
ofqualified skilled persons.
▶ Before using the axial piston unit, please read the
instruction manual (parts I and II) completely and
thoroughly. Ifnecessary, this can berequested from
BoschRexroth.
▶ Before finalizing your design, please request abinding
installation drawing.
▶ The specified data and notes contained herein must
beobserved.
▶ Pressure controllers are not safeguards against pressure
overload. A separate pressure relief valve is to be
provided in the hydraulic system.
▶ Depending ontheoperating conditions oftheaxial
piston unit (working pressure, fluid temperature),
thecharacteristic curve may shift.
▶ Not all versions ofthe product are approved foruse
inasafety function according toISO13849. Please
consult theproper contact atBoschRexroth ifyou
require reliability parameters (e.g. MTTF
d
) forfunctional
safety.
▶ Working ports:
– The ports and fastening threads are designed forthe
specified maximum pressure. The machine orsystem
manufacturer must ensure theconnecting elements
and lines correspond tothe specified application
conditions (pressure, flow, hydraulic fluid,
temperature) with thenecessary safety factors.
– The working ports and function ports are only
intended toaccommodate hydraulic lines.
