Important!
Do not exceed the pipe forces.
Ensure measures are in place for complete ventilation during
the laying procedure.
Pressure pipes
-
lay in a frost-free configuration,
-
secure and
-
connect so they are stress-free.
Pipe forces and moments should not affect the pump.
Install a ...
- gate valve immediately in front of the pump to close off
the pipes. This enables the pump to be removed when the
pipes are full.
- non-return valve between the pressure flange and gate
valve. This prevents the pumped medium from flowing
back after shutting off the pump and also it avoids liquid
slugging.
5.11 Soiling monitor of the filter strainer
The degree of soiling of the filter strainer (002) can be
checked via a digital pressure sensor or a pressure-and-
vacuum gauge with shut-off valve. Attach it to the top screw
connection (005.2) of the filter casing (001).
Important!
Note the starting value of the pressure when using a digital
pressure sensor.
5.12 Frost protection
Notice!
The effects of frost can damage the filled pump.
Empty pumps during prolonged periods of inactivity.
Important!
Ensure the pump casing is free from pressure.
Open the ball valve (006).
Only then should you empty the pump.
For UNIBAD-XC pumps
- see section 9.1 'Disassembly for draining',
- Attach the cooling pipes according to section 9.2 'Assembly
before recommissioning'.
Important!
Before recommissioning, close the ball valve (006).
