Service/Maintenance
S1 Regularly check the packing for leaks.
S2 Ensure a good lubrication schedule (only with oil-
lubricated bearings).
S3 Regularly check for bearing play.
S4 Ensure a good service plan
S5a Check oil level (according to (EN 13463-5:2003 §6.2)
(Only with oil-lubricated bearings)
S5b Check coolant level (according to EN 13463-5:2003
§5.4).
S6 Check for bearing leaks.
S7 If a leak occurs to the mechanical shaft seal: stop the
pump.
S8 Regularly check the coupling and elastomers of the
coupling.
S9 Ensure the correct spare parts
also ensure correct fitting with shaft and bush
S10 Check alignment, damage to protective cover
S11 Regularly check the safety devices on the pump (unit)
Safety device
B1 Ensure direction of rotation protection
(electrical/mechanical).
B2a Ensure regular checks for leakage and adjust if
necessary.
This applies for:
• the auxiliary system
B2b Choice of seal only to be determined after consultation
with the supplier.
(Only with Cat. 2 pumps)
With extra guarantee against leakage.
• Only when pumping volatile liquid.
• Apply safety device for coolant presence.
B4a Protect the pump against overpressure. Set the max.
pressure to 10% above the original pump curve.
(Only with Cat. 2 pumps)
Only required when pumping volatile liquid and/or
dangerous liquid.
• Or with a dangerous liquid.
B4b Protect pump against underpressure. The maximum
suction head depends on the NPSH value indicated on
the pump curve.
(Only with Cat. 2 pumps)
Only required when pumping volatile liquid.
B5 Protect pump against temperature.
(Only with Cat. 2 pumps)
Bearing temperature.
• Mechanical shaft seal.
B6 Protect electric motor against overloading
In the case of overloading the motor may not become
too hot. This is the case with an ATEX motor.
B7 Protection of supplied power.
