Re-Assembly:

d)

Screw in the impulse nozzle into the Pulsor body without using a sealant and first tighten it by hand. Use
a screw wrench to tighten it by 1/8 - 1/4th of a revolution.

e)

Insert the Pulsor with the impulse nozzle into the weld-on nipple. Align the Pulsor and the nozzle in such a
way that the valve can be installed easily. Firmly tighten the union nut of the assembly union. 

f)

Attach the valve, tighten the pipe union and fit the solenoid valve plug back on again.

3. Repair of the Pulsor:

Pulsor type 100, 150 und 300

1.1

Bottom

1.2

Plate 

1.3

Sealing diaphragm

1.4

Valve disc

1.5

Plate spring

1.6

Seat ring (with Pulsor type 100 two-part)

1.7

./.

1.8

Cover

1.9

Hexagon socket screw

1.10

Pipe double nipple, conical

1.11

Pipe union (screw-in part)

1.12

Monitoring sensor (optional)

1.13

Angle plug (optional)

1.14

Sealing (optional)

a)

Remove the hexagon screws (1.9) and detach the Pulsor cover (1.8) from the Pulsor bottom (1.1). (Some-
times the cover adheres to the rubber diaphragm and can not be removed easily at once. For that reason
wait a few minutes after loosening the screws, until the cover can easily be removed (or carefully use a
screw driver or little chisel to open the housing.)

b)

Inspect the Pulsor plate (1.2): The plate must be firmly glued into the bottom. When hit slightly with e.g. a
screw driver, a bright and clear sound must be heared. The sealing edge of the plate, on which the rubber
diaphragm sits, must not be damaged or have notches. The edge must protrude uniformly about 0,2 - 0,3
mm from the sealing surface of the bottom. If the Pulsor plate is damaged or loosened, the Pulsor should
be sent in for repair.

c)

Inspect the valve disk and sealing diaphram (1.3+1.4) and replace it, if you discover ruptures or wear and
tear. The rubber diaphragm (1.3) must be firmly glued to the disk (especially at the inner perimeter), ex-
cept of a narrow zone along the edge of the disk (1.4). The central bore hole in the disk must not be clog -
ged. Its diameter is crucial for the working frequency of the Pulsor.

d)

Inspect the plate spring (1.5) and the seat ring (1.6), and replace the parts, if worn.

e)

If present, check the monitoring sensor (see chapter 6.3 of the operating manual). If the sensor is defect,
the Pulsor should be sent in for repair.

f)

Reassemble the Pulsor, referring to the above sketch, paying attention to a good centering of the disk and
diphragm (1.3+1.4).
