The effect on the environment is subjective and depends largely on the correct
installation and the nature of the rest of the remaining system.
Foundation
Vibration damping is best achieved if the pump is set up on a flat, solid concrete
foundation.
As a guideline, the concrete foundation should be 1.5 times as heavy as the
pump.

6.3.5.1 Flushing fluid (optional)
Requirements of the flushing fluid
The flushing fluid has the task to lubricate and cool the product-side mechanical
seal and the radial packing ring on the atmospheric side.
The flushing fluid must meet the following criteria:
•
good flowability
•
no impurities
•
no solids
•
no dissolved components
•
adequate thermal conductivity
•
no chemical or mechanical attacking of the pump materials, sealing materials,
and elastomers.
•
No contaminating of the pumped fluid
•
Viscosity < 5 mPas
•
Water hardness < 5° dH
Demineralised water meets these requirements to a large extent.
6.3.5.2 Flushing systems
Simple mechanical seal
The single mechanical seal is designed for hygienic applications and covers most
common operating conditions in terms of operating pressure, temperature and
speed.
