14.3 Assembly/disassembly of spare parts

14.3.1 Pulsation damper disassembly (removing actuator from
body)
1. Move the actuator A to the open position (see "Control
function", page 18).
2. Loosen the fastening elements between pulsation damper
body 1 and actuator A diagonally and remove them.
3. Lift actuator A off pulsation damper body 1.
4. Move the actuator A to the closed position (see "Control
function", page 18).
Important:
▶ Clean all parts of contamination (do not damage the
parts during cleaning) following removal. Check parts for
potential damage; replace if necessary (only use genuine
parts from GEMÜ).
14.3.2 Removing the diaphragm
▶ Before removing the diaphragm, remove the pulsation
damper, see "Pulsation damper disassembly (removing
actuator from body)".
1. Unscrew the diaphragm.
2. Clean all parts of contamination. Do not scratch or dam-
age parts during cleaning!
3. Check all parts for potential damage.
4. Replace damaged parts.
14.3.3 Mounting the diaphragm
14.3.3.1 General information
▶ Install the diaphragm suitable for the pulsation damper
(suitable for medium, medium concentration, temperat-
ure and pressure). The diaphragm is a wearing part.
Check the technical condition and function of the pulsa-
tion damper prior to commissioning and during the whole
duration of use. Carry out checks regularly and determine
the check intervals in accordance with the conditions of
use and/or the regulatory codes and provisions applic-
able for this application.
▶ Take care that the diaphragm is correctly installed, so as
to ensure that the pulsation damper works.
