Maintenance and repair
specified! If strong vibrations occur during operation, the pump or installation must be
checked regardless of the specified maintenance intervals.
2 years
▪ Visual inspection of the power supply cable
▪ Conduct visual inspection of accessories
▪ Visual inspection of the housing for wear
▪ Function test of monitoring devices
▪ Oil change
NOTICE! If sealing chamber control is installed, the oil is changed according to the indi-
cator!
10 years or 5000 operating hours
▪ General overhaul
Under harsh operating conditions, the specified maintenance intervals must be shortened, if
necessary. Harsh operating conditions include:
▪ Fluids with long-stranded components
▪ Turbulent intake (e.g. due to air intake, cavitation)
▪ Highly corrosive or abrasive fluids
▪ Highly gaseous fluids
▪ Operation at an unfavorable duty point
▪ Pressure surges
If using the pump under harsh conditions, signing a maintenance contract is recommended.
Please contact the customer service.
WARNING
Attached macerator: sharp edges on the cutting plate and rotating blade!
The macerator can cause amputation of limbs! Wear safety gloves to protect against cuts
and never reach into the macerator!
WARNING
Hand, foot or eye injuries due to a lack of protective equipment!
During work there is a risk of (serious) injury. Wear the following protective equipment:
• Safety gloves that protect against cuts
• Safety shoes
• Closed safety goggles
Before starting the maintenance measures the following requirements must be fulfilled:
▪ Pump cooled to ambient temperature.
▪ Pump thoroughly cleaned and (if necessary) disinfected.
For smooth operation, it is recommended to carry out regular inspections of the current
consumption and the operating voltage in all three phases. In normal operation, these values
remain constant. Slight fluctuations may occur depending on the characteristics of the fluid.
Using the current consumption, damage or malfunctions in the impeller, bearings, or motor
can be identified at an early stage and rectified. Large voltage fluctuations strain the motor
winding and can cause the pump to break down. Regular inspections can prevent major sec-
ondary damage and reduce the risk of total breakdown. With regard to regular inspections,
the use of remote monitoring is recommended.
