1Device description
The P4 pressure pump is used for checking, adjusting and calibrating all kinds of pressure
equipment.
It was specifically developed for low pressures up to 4
bar. It is also possible to generate negative pressure,
but this is very dependent on the test chamber volume.
The pressure pump can be used for test items directly
on location, thanks to its light weight and compact de-
sign.
When the pressure pump is used, it needs to be con-
nected to a reference gauge and to the test item (§ 3
"Function").

General safety instructions:
In all work, the existing national regulations for accident prevention and safety in the
workplace must be complied with. Any internal regulations of the operator must also be
complied with, even if these are not mentioned in this manual.
Never use the pressure pump together with an external pressure source. Do not attach
an external pressure generator to the pressure pump.
Do not remove any attached components (test item, pressure hose, reference gauge)
when the pressure pump is under pressure:
Open the pressure relief valve before removing any of the components.
Do not use Teflon tape to seal the pressure connections. Surplus Teflon tape can enter
the pressure pump and damage it.
Only use adapters and seals that are available as accessories.
Non-pressurised storage: Only store the pressure pump with the pressure relief valve
open. This ensures that no pressure can be built up by unintentional pumping move-
ments.
Avoid external force of all kinds towards the pressure pump and its operating elements.
Do not use the pressure pump if it is damaged or defective.

P4 Construction and function
Technical changes reserved
3Construction and function
Construction:
Pump grip.
Piston rod.
Lock-on button.
Pump body with hand grip.
Connector reference gauge.
Fine adjustment valve (hand wheel).
Pressure relief valve (rotary knob).
Pressure hose with cap screw (test item
connection).
Function:
The correct functioning of the P4 pressure pump requires the pressure-proof connection of a
reference and a test item . The test item respectively the pressure device to be tested
(hereafter referred to as 'test item') is connected to the cap screw of the pressure hose .
The upstream pressure in the measurement setup is
generated by the integrated piston pump + . The
number of pump movements depends on the required
test pressure and on the volume of the measurement
setup.
To perform tests at low pressure, a 100-percent seal-
ing of the test chamber is required. To accomplish
this, an additional valve – the test chamber valve – is
closed between the pump room and the test chamber
Set the pressure to the required value through the fine
adjustment valve .
The pressure can be correspondingly reduced or com-
pletely relieved with the pressure relief valve .
The generated pressure is displayed on the reference test gauge and compared with the
measurements of the test item .

Commissioning P4
© SIKA • Ba_P4 • 04/2014
4Commissioning
In order for the pressure pump to be operated, it is vital that its connections with the refer-
ence gauge and the test item are pressure-resistant. The pressure hose is supplied already
bolted on to the pressure pump and should not be removed.
CAUTION! Material damage!
The test item must have absolutely nothing adhering to it (oil, grease, water ...).
Impurities can be transported into the pressure pump via the pressure hose, causing
damage to the pump.
Maximum torque of the pressure connections!
Reference: 15 Nm
Test item: 15 Nm
Complete the following steps before using the pressure pump:
Screw the reference gauge tightly to the top of the pressure pump with the correct seal
(Connector reference gauge G ¼).
Clean the connection of the test item and ensure that no oil or other substances can en-
ter into the pressure hose.
Select the suitable adapters and seals for the test item's connection.
Join the adapters and seals to the test item and the cap screw of the pressure hose
(G ¼). Whilst doing this ensure that the O-ring is correctly positioned in the cap screw.
5Operation
CAUTION! Damage to valve stop!
If put under too much strain the stop and the pressure pump will be damaged.
Only continue to tighten the valves (the fine adjustment, pressure relief and switch
valves) by hand, once the stop has been reached.
Before using the device, check that
the reference gauge is connected to the pressure pump.
the test item is joined to the pressure hose.
all pressure connections are correctly in place, so that they resist pressure.

P4 Operation
Technical changes reserved
5.1 Generating pressure
CAUTION! Damage to test item!
Adhere to the maximum pressure of the test item!
Only create an admission pressure with the pump that is lesser than the necessary test-
ing pressure. Following this carefully increase the pressure using the fine adjustment
valve.
Preparation:
If necessary, switch on the reference manometer and the test item.
Close the pressure relief valve.
Turn the valve knob clockwise to the limit stop.
Place the integrated test chamber valve in the pump position.
To do that, turn the pump handle counter-clockwise to the limit stop.
Build up upstream pressure:
Hold the pressure pump tight with one hand on the handle and the other on the pump
grip.
Build up the upstream pressure through repeated pump movements.
The larger the volume of the test chamber, the more pump movements are needed.
Seal the test chamber (required at pressure < 1 bar):
Push in the piston rod on the pump grip until the limit stop.
Slightly press down the lock-on button on the handle.
IMPORTANT! If the piston rod is not in the correct position, the lock-on button cannot
latch in.
Now turn the pump grip clockwise up to the limit stop.
The test chamber valve is closed.
Setting the test pressure:
Use the fine adjustment valve to precisely set the required test pressure.
• Turn the hand wheel clockwise to increase the pressure.
• Turn the hand wheel counter-clockwise to reduce the pressure.
Turn the hand wheel accordingly to set the required test pressure.
FINE ADJUSTMENT VALVE
When it is not under pressure the fine adjustment valve
moves very freely. The wide hand wheel of the fine ad-
justment valve can be moved into the needed position
very easily using with the palm of the hand.

5.2 Generating negative pressure
The generated negative pressure depends greatly on the volume of the test chamber. The
smaller the test chamber volume, the smaller the negative pressure can become.
The maximum generated negative pressure is approximately -0.3 bar.
Preparation:
If necessary, switch on the reference manometer and the test item.
Turn the hand wheel of the fine adjustment valve counter clockwise up to the "Pump body
limit stop".
Seal the test chamber.
• To do this, press the pump grip to the limit stop in the pump body.
• Keep the lock-on button pressed down
• Turn the pump grip clockwise up to the limit stop.
Close the pressure relief valve.
To do this, turn the valve knob clockwise up to the limit stop.
Generating negative pressure:
Turn the fine adjustment valve hand wheel counter-clockwise in the direction of the
“Pressure relief valve limit stop” until the required negative pressure is attained.
