4.10 Customer-provided cooling systems and lubrication systems
In case the customer orders a gear unit for which SEWEURODRIVE recommends us-
ing pressure lubrication and/or an additional cooling system, refer to this chapter for
guidelines on how to select the components.
First, define the following:
• The oil quantity Q
P
required to be provided by the motor pump
• The cooling capacity P
L
required to be provided by the oil-water/oil-air cooling sys-
tem.
INFORMATION
• If a customer-provided pressure lubrication and/or additional cooling system is
used, contact
SEW‑EURODRIVE . We will assist you in the technical configura-
tion, such as regarding oil flow rate, oil pressure, and oil temperature.
• If the the gear unit is designed for operation with a customer-supplied pressure lu-
brication system, the gear unit must not be operated without this pressure lubrica-
tion system.
SEW‑EURODRIVE recommends using the following additional components and in-
struments:
• Oil filter with a minimum filtration level of 25 μm.
• Control switch for functional test of the motor pump, e.g. pressure switch.
• When using a cooler: For example, controlling the oil temperature in the cooler's
return pipe using a thermal switch or optical thermometer.
