Maintenance and repair
▪ Maintenance tasks: The technician must be familiar with the use of operating fluids and
their disposal. In addition, the technician must have basic knowledge of mechanical en-
gineering.
▪ Provide the necessary protective equipment and make sure that the personnel wears it.
▪ Collect operating fluids in suitable tanks and dispose of properly.
▪ Dispose of protective clothing used in accordance with regulations.
▪ Use only original parts of the manufacturer. Use of parts other than the original parts
releases the manufacturer from any liability.
▪ Collect any leakage of fluid and operating fluid immediately and dispose of it according
to the locally applicable guidelines.
▪ Provide the tools required.
▪ If flammable solvents and cleaning agents are used, open flames, naked lights and
smoking are prohibited.
Medicinal white oil is filled into the sealing chamber ex-factory. The following oil types
are recommended when changing the oil:
▪ Aral Autin PL*
▪ Shell ONDINA 919
▪ Esso MARCOL 52* or 82*
▪ BP WHITEMORE WOM 14*
▪ Texaco Pharmaceutical 30* or 40*
All oil types marked with "*" are approved for use with foods in accordance with
"USDA-H1".
▪ Single-channel hydraulics (PRO C...)
– P 13.1... motor: 1100 ml (37 US.fl.oz.)
– P 13.2... motor: 1100 ml (37 US.fl.oz.)
– P 17.1... motor: 1800 ml (61 US.fl.oz.)
▪ Vortex hydraulics (PRO V...)
– P 13.1... motor: 900 ml (30 US.fl.oz.)
– P 13.2... motor: 1500 ml (51 US.fl.oz.)
– P 17.1... motor: 1800 ml (61 US.fl.oz.)
To ensure reliable operation, maintenance tasks must be carried out regularly. Depend-
ing on the real ambient temperatures, maintenance intervals different from those men-
tioned in the contract can be defined! If strong vibrations occur during operation, the
pump and the installation must be checked regardless of the defined maintenance in-
tervals.

▪ Visual inspection of the power supply cable
▪ Visual inspection of accessories
▪ Visual inspection of the coating and housing for wear
▪ Function test of monitoring devices
▪ Oil change
NOTICE! If sealing chamber control is installed, the oil is changed according to the
indicator!
10 years or 15000 operating hours
▪ General overhaul
When the pump is used in sewage lifting units inside buildings or on plots of land, carry
out maintenance intervals and measures in accordance with DIN EN 12056‑4!
Under harsh operating conditions, specified maintenance intervals must be shortened if
required. Harsh operating conditions include:
▪ Fluids with long-fibre components
▪ Turbulent inlet (e.g. due to air intake, cavitation)
▪ Strongly corroding or abrasive fluids
▪ Heavily gas generating fluids
▪ Operation at an unfavourable duty point
▪ Pressure surges
