Pressurisable buffer fluid tank
The pressurisable buffer fluid tank (hereafter referred to as "tank") with manual air pump ensures a constant
and defined buffer chamber pressure (buffer chamber pressure = tank pressure).
The tank provides reliable monitoring of the buffer chamber.
Installing the tank
(before pump start-up)
1.
Remove the plug from the buffer chamber.
2.
Open the tank: undo the upper coupling of the upper housing (hold the union nut firmly in place so that
the lower coupling is not detached).
3.
Screw the tank directly into the cast body of the buffer chamber. Fill the tank about one quarter full
(when delivered, the buffer chamber is already filled).
4.
Close the tank and use a manual air pump or a compressed-air supply outlet to set the required tank
pressure.
Topping up buffer fluid
(maintenance and inspection)
Fig.
"Buffer fluid tank" and "Filling/draining the buffer chamber"
1.
Release the pressure in the buffer chamber via the valve on the tank.
2.
Open the tank: undo the upper coupling of the upper housing (hold the union nut firmly in place so that
the lower coupling is not detached).
3.
Top up the buffer fluid in the tank. The tank must be one quarter full.
4.
Close the tank and use a manual air pump or a compressed-air supply outlet to set the required tank
pressure.
