Determining Pipeline Lengths; Optimising Cross Sectional And Direction Changes; Avoiding Overpressure - ITT Bornemann SLH-4U Operating Instructions Manual

5.6.3 Determining pipeline lengths

5.6.4 Optimising cross sectional and direction changes

5.6.5 Avoiding overpressure

Outlet line nominal width ³ Specify the outlet line nominal width.
3.
Maintain recommended minimum values for installation of the pump.
Inlet side: shorter lengths are possible, however, doing so may
restrict the hydraulic performance data.
Outlet side: shorter lengths are possible, however, doing so may
lead to increased noise.
1. Avoid sudden changes in cross section and direction in the pipe course.
Parallel operation of pumps only with express approval of ITT
Bornemann GmbH.
2. If multiple pumps are operated in parallel and gas-charged media is being
pumped:
n Ensure that the pressure conditions are the same for each pump by
running the pipes symmetrically.
Use identical cross sections and line lengths from the common supply
n
line to the pumps.
3. Ensure that no cavitation can occur.
4. Account for thermal expansion.
In the event of advice being required regarding the optimisation of the pipe
work system please contact ITT Bornemann GmbH.
WARNING!
Danger of injury due to overpressure!
– If there is no overpressure safety valve in the pump: Provide
suitable safety device (e.g. burst disc) in the outlet line.
1. Observe the manufacturer's instructions.
2. Ensure that the factory setting of the safety device complies with the
system requirements.
3. Always guide the safety device return into the safe area (pressureless
area).
4. Constantly monitor the pressure build-up, in order to exclude impermissible
pressure build-up.
