Page 6: General
The personnel in charge of installation, operation and maintenance of the dampener we produce must be qualified to carry out the operations described in this manual. Tapflo shall not be held responsible for the training level of personnel and for the fact that they are not fully aware of the contents of this manual. -
Page 7: Installation
INSTALLATION INSTALLATION 1.1. Operation principle 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. -

Page 9: Explosion Hazardous Environments - Atex
1.4.2. Explosion hazardous environments – ATEX The standard DT series dampeners are not allowed to operate in environments where there is danger of explosion. Static electricity may occur in the dampener under operation, which may cause explosion and injury. Special conductive DTX dampeners are available for such applications. -
Page 10: Temperature Hazards
INSTALLATION 1.4.5. Temperature hazards ➢ Raised temperature can cause damage on the dampener and/or piping and may also be hazardous for personnel in the vicinity of the dampener/piping. Avoid quick temperature changes and do not exceed the maximum temperature specified when the dampener was ordered. -

INSTALLATION 1.6. Example of installation 1.6.1. Standard pump 1.6.2. TF pump The pulsation dampener must be installed according to the sketch. It can be connected with a nipple immediately after the pump outlet, or placed independent of the pump with a flexible hose between the pump and the dampener. -
Page 12: Operation
OPERATION OPERATION 2.1. Before operating the dampener ➢ Make sure the dampener is installed according to the installation instruction. ➢ When installation is new or the dampener is reinstalled, a test run with water must be conducted to make sure that the dampener operates normally and does not leak. ➢... -

MAINTENANCE 3.5. Disassembly of the dampener The numbers put in brackets, refer to the part numbers in the spare part drawings and spare part lists in chapter 5 “Spare parts”. 3.5.1. Before the disassembly procedure Be sure to drain all liquid from the dampener. Cleanse or neutralize the thoroughly. Disconnect the air supply and then the inlet and outlet. - Page 16 MAINTENANCE Fig. 3.5.5 Take the pin screws [14] out of the dampener housing [11]. Fig 3.5.6 Unscrew the diaphragm [15] by hand (clockwise). Fig 3.5.7 Using an Allen key, unscrew the shaft ending [1652] from the diaphragm. Fig 3.5.8 Push out the shaft [1651] from the dampener housing Fig 3.5.9 Check the inner seals [36] and O-rings [47].

MAINTENANCE 3.6. Assembly of the dampener The assembly procedure is done in the reverse order to the disassembly. Nevertheless there are a few things that you have to remember in order to assemble the dampener correctly. Fig. 3.6.1 Using a screwdriver, insert the O-rings [47] into the dampener block [12]. - Page 18 MAINTENANCE Fig. 3.6.6 Push the diaphragm [15] in, so that it is touching the dampener block [12]. Fig. 3.6.7 Put the pin screws [14] and washers [38] into the dampener housing [11]. Fig. 3.6.8 Screw the nuts [37] onto the pin screws [14] so that ca.

MAINTENANCE Fig. 3.6.12 Insert the nut covers [579] on both sides of the dampener. Fig. 3.6.13 Insert the muffler [25] and the circlip [27] in a circular manner. 3.6.1. Test run We recommend you to conduct a test of the dampener before installing it in the system, to detect if there is no air leakage through diaphragm shaft. -
Page 20: Options
OPTIONS 4. OPTIONS 4.1. DTB series The DTB series equipped with fully pneumatic control system “Guardian” is perfect choice when the diaphragm rupture has to be immediately detected in order to avoid product leak to the environment. When rupture is detected the pump is automatically stopped and an alarm can be generated. -
