INSTRUCTION MANUAL
1. General information
Dear customer, congratulations for purchasing a
Rothenberger product. The testing pump TP25 has
been developed and designed to meet the highest
quality standards guaranteeing most stringent operation
requirements.
A number of unique design features make the pump
different from other testing pumps.
• Double shut-off and purge valve system, to ease test
pressure adjustment.
• Combined ball head and monoblock shut-off valve
system reducing risk of leaks in the system.
• Distortion proof wear resistant brass.
• Knock resistant weather and cold-proof galvanised steel
tank protected with Duramant ® epoxy coating.
• Pressure gauges with readily available calibration
certificates.
At present, a great number of installations for fluid-
carrying pipes can be found depending on the type and
nature of the pipe materials. These can be of metal (steel,
INDEX
stainless steel, galvanised steel, aluminium, copper...)
plastic materials (PP, PE, PB, PVC, PE-X...) as well as
composite materials such as Multilayer. All these types
of pipes can be joined depending on of the material and
the nature of the joint by means of welding, threads,
mechanical joints with bushings or using adhesives ...
No matter the nature of the joint, the type of material
and the fluid to be carried, any installation must be liquid-
tight, requiring test.
Testing pump TP25 is a precision tool for testing
installation tightness using water or oil as testing liquid,
with maximum possible testing pressure of 25 bar .
2. General safety
6
1. Prior to starting the testing pump, please carefully read
and follow these instructions.
6
2. The position and operation of the controls must be
studied prior to TP25 pump operation
3. The TP25 has been designed for specific applications. We
6
strongly recommend that it SHOULD NOT BE MODIFIED,
nor used for other purposes.
4. Using only the liquids specified for the tests is utterly
7
important for the integrity and durability of the liquid-
tight systems. NO acids or other corrosive liquids may
7 be used for the tests. Use only clean water or Oil as an
alternate.
5. Check the pump for damaged or defective parts prior
7
to pump operation. The pump MAY NOT BE USED if
pressure hoses or any other parts are flawed or broken.
6. Only original Rothenberger parts should be used for
maintenance
3. Operating instructions
1. Connect the pressure hose to the equipment to be tested
with valve V1 opened and valve V2 closed (Pag 2.1).
2. Open one or several purge points in the installation.
Remove the handle-locking hook and pump liquid until
all air has been purged from the installation. Close the
vent points. Fill the installation operating the pump
handle with ample movements (Pag 2.2).
3. Keep on pumping until the test pressure has been
reached (Pag 2.3).
4. Close valve V1 (Pag 2.4).
5. If the test pressure is exceeded during the pumping
operation, slightly open valve V2 until the required
pressure is attained. Then close all the valves (Pag 3.5).
6. If no leaks are present, no pressure drop will be detected
in gauge readings. At test completion, open both valves
V1 and V2 (Pag 2).
NOTE
!
After the pressure has been reached, wait for the
pressure to stabilize. If required, pump again until the
pressure is reached again.
4. Maintenance
Keep the tank and pump system clean. The suction pipe
is supplied with a filter to prevent dirt entering the pump
pressure system. If the filter should clog, remove the dirt
and clean it with water.
Grease the piston periodically with water repellent grease.
Be extremely careful not to damage the piston (Pag 3.7).
