9 Maintenance
9.1 Maintenance
•
Observe the information provided in
section 2 Safety whenever performing
maintenance and repair tasks.
•
Regular monitoring and maintenance of
the pump and drive will extend the service
life.
Caution!
Use protective equipment
whenever necessary.
9.1.1 General monitoring
•
Do not run the pump dry.
•
Do not overload the drive motor.
•
Check suction and pressure lines for leaks.
•
A stuffing box must drip slightly during
operation. A mechanical seal may not
have any significant leaks.
•
Observe pressure- and temperature-
monitoring devices and compare them with
the order data sheet and inspection
protocol.
•
Additional equipment like flushing, sealing,
or quenching of the shaft seal must be
monitored if present.
•
Monitor additional equipment for heating or
cooling the stuffing box casing and/or the
stator and/or the suction casing, if present.
9.1.2 Universal joints
Universal joints must be lubricated with
ALLWEILER special joint oil of type B or oil
ET1510 ISO 460 from Tribol Lubricants GmbH
of Mönchengladbach, Germany; if the pump is
employed in the food industry, use
ALLWEILER special joint oil type BL or oil
1810/460 from Tribol Lubricants GmbH.
Caution!
We have not tested any other
lubricants and therefore cannot
recommend any others!
The joints have lifetime lubrication. However, if
the pump must be opened for other reasons,
we recommend checking the joint collar for
leaks and replacing the joint oil after 8000
operating hours. The table in section 9.1.7
Page 25 shows the oil quantity in cubic
centimeters for various pump sizes. Refer to
section 10 page 26 for information on changing
the joint oil.
9.1.3 Drive shaft bearing and
bearing lubrication
The drive shaft bearings in the bearing bracket
are regreasable angular contact and groove
ball bearings.
Notice!
The groove ball bearing with
vertical pump installation is lifetime
lubricated.
Grease for antifriction bearings
We recommend using the antifriction bearing
grease listed below or grease of equal quality
for lubrication of the ball bearing. The order of
the listing does not indicate a quality ranking.

Tab. 8 Overview of antifriction bearing grease
If none of the antifriction bearing greases listed
above are available, we recommend using a
multi-purpose lithium-based grease that
complies with the DIN designations above.
Mixing different types of grease with differing
base oils and thickening agents will lower the
lubrication properties and must therefore be
avoided.
The table in section 9.1.7 on page 25 shows
the grease volume in grams for various pump
sizes.
Relubrication time
The bearing must be relubricated every 4000
operating hours.
