IOM manual Active pulsation dampeners 4
0.1 Introduction
The active pulsation dampener is the most efcient way to remove pressure variations on the
discharge of the pump. The Tapo pulsation dampener works actively with compressed air and a
diaphragm, automatically setting the correct pressure to minimise the pulsations. The pulsation
dampener is available for all Tapo pump sizes and material versions.
With proper attention to maintenance, Tapo active pulsation dampeners will give efcient and
trouble free operation. This instruction manual will familiarise operators with detailed information
about installing, operating and maintaining the dampener.
0.2 The warning symbols
The following warning symbols are present in this instruction manual. This is what they say.
This symbol stands next to all safety instructions in this instruction manual where danger
to life and limb may occur. Observe these instructions and proceed with utmost cau-
tion in these situations. Inform also other users of all safety instructions. In addition to
the instructions in this instruction manual, the general safety and accident prevention
regulations must be observed.
This signal stands at points in this instruction manual of particular importance for com-
pliance with regulations and directives, for correct work ow and for the prevention of
damage and destruction of the complete dampener or its subassemblies.

1. INSTALLATION & SAFETY
1.1 Receiving inspection
Although precaution is taken by us when packing and shipping, we urge you to carefully check
the shipment on receipt. Make sure that all parts and accessories listed on the packing list are
accounted for. Immediately report any damage or shortage to the transport company and to us.
1.2 Storage
If the equipment is to be stored prior to installation, place it in a clean location. Do not remove the
protective covers from the suction, discharge and air connections which have been fastened to
keep pump internals free of debris. Clean the dampener thoroughly before installation.
1.3. Installation of the dampener
The pulsation dampener is installed according to the sketch. It can be connected with a nipple im-
mediately after the pump outlet, or placed independent of the pump with a exible hose between
the pump and the dampener.
Note! Make sure that the dampener does not cause any tension or strain to the pump.
The dampener should have its own support assembly. Any stress casused by the dampener on
the outlet manifold can result in deformation of parts and leakage of the pump.
The air hose is connected to the pump air hose with a T-connection, between the pump and regu-
lator / valves (See sketch). It is important that the air to the dampener must have the same ow
and pressure as to the pump!
In order to ensure the most effective pulsation dampening the dampener should be installed not
further than ve times the diameter of the pipeline from the discharge ange of the pump - L<5* Ø.

1. INSTALLATION & SAFETY
1.4 Operation principal
The pulsation dampener’s main function is to remove pressure variations on the discharge of the
pump. The dampener works actively with compressed air and a diaphragm, automatically setting
the correct pressure to minimise the pulsations.
The air pressure supplied to the dampener is the same as the one supplied to the pump. The
medium owing through the dampener affects the diaphragm, which by means of the compressed
air on the air side compensates the uctuations of pressure in the discharge line. The air concen-
trated in the dampeners block works as a spring for the medium owing through the dampener.
Before starting the pump and dampener.
- Make sure the pump is installed according to the installation instruction.
- When installation is new or re-installed, a test run should be conducted to make sure the
dampener operates normally and does not leak.
- When installation is new or re-installed, check the dampener housing nut tightening torque.
After approx. 1 week of operation, the torque should be checked again. This is important
to prevent leakage.
1.5 Health & Safety
The dampener must be installed according to local and national safety rules.
The dampeners are constructed for particular applications. Do not use the dampener on applica-
tions different from that for which it was sold without consulting Tapo AB to ascertain its suitability.

IOM manual Active pulsation dampeners 7
1.5.1. Protection
In the interest of health and safety it is essential to wear protective clothing and safety goggles
when operating, and/or working in the vicinity of Tapo dampeners.
1.5.2. Explosion hazardous environments – ATEX
Static electricity may occur in the pump under operation, which may cause explosion
and injury. Special conductive pulsation dampeners DTX are available for such applications.
Follow below instructions and local/national rules for safe use.
ATEX (directive 94/9/EC) classication of Tapo DTX dampeners:
ATEX II 2 GD IIB cT4
Equipment group II – all other explosive areas than mines;
Category group 2 – high level of protection (can be used in zone 1);
Atmosphere G– gas; D– dust;
Explosion group IIB – such as ethylene;
Type of protection c– constructional safety;
Temperature class T4 – in the event of a malfunction, the maximum temperature of a surface that
may be exposed to gas T4 = 135 °C.
Earth connection of dampener and other equipment
Connect a suitable earth wire to the stainless steel earth connection that is placed on the inside
of one of the pump housings. Connect the other end of the earth wire to earth and also make sure
that other equipment like hoses/pipes/containers etc. are properly earthed/connected.
1.5.3. Air pressure
The maximum air pressure for Tapo dampeners is 14 bar. Higher air pressure than 14 bar can
damage the dampener and may cause injury to personnel in vicinity of the dampener.
Please make sure that supply air to the dampener must have the same ow and pressure as the
pump that dampener is installed with.
1.5.4. Noise level
At tests, the noise level from a Tapo dampener has not exceeded 70 dB(A).
1.5.5. Temperature hazards
Raised temperature can cause damage to the dampener and/or piping and may also be hazar-
dous for personnel in the vicinity of the dampener/piping. Avoid quick temperature changes and
do not exceed the maximum temperature specied when the dampener was ordered.

2.1. When dampener is new or re-assembled
If the dampener is new or re-assembled after maintenance it is important to re-tighten the
dampener housing screws (pos. 37) after a few days of operation. Make sure to use the right
torque, see chapter 4.2.
2.2. Routine inspection
Frequent observation of the dampener operation is recommended to detect problems.Achange in
sound of the running dampener can be an indication of wear. Leakage of liquid from the dampener
and changes in performance may also be detected. Routine inspections should be conducted
frequently.
2.3. Location of faults

3. SPARE PARTS
3.5 Recommended spare parts
Even at normal operation some elements in the dampener are subject to wear. In order to avoid
expensive breakdowns we recommend having a few spare parts in stock. These are:
3.6 How to order parts
When ordering spare parts for Tapflo dampeners, it will simplify the process if you give
the model and serial number from the nameplate of the dampener, position number of the part
and quantity.
