Hydrostatic test hand pumps WAP0025, WAP0045, WAP0050, WAP0100
ASSEMBLY AND OPERATING INSTRUCTIONS
The components are shipped unassembled to prevent breakage or unnecessary bulk during transport or the stockage
in warehouse.
The pump is provided with pressure gauge, coil and double control valve. On demand, we can provide a delivery
flexible hose, designed to withstand the pressure rating.
Assemble the device in accordance with the next procedure, first checking that you have all the necessary material.
Use PTFE tape on all threads.
Before starting any operation, clean the tank to eliminate any residue or waste.
1.
Screw suction pipe into the base of the pump.
2.
Assembly the pump on the bridge of the tank.
3.
Screw in the valve unit, ensuring the connection hole for the gauge tube is opposite the outlet and is vertical.
4.
Screw the gauge tube and mount the gauge. In order to favour the immediate reading during the test, point
the pressure gauge in the direction of the operator. Remember to apply necessary seals to all components.
5.
Check that all connections are tightened and connect the pump to the tank using the supplied screws.
6.
Fill up the tank and ensure the suction tube is completely submerged. Use anticorrosive, antioxidant fluid or a
mixture of water and emulsifiable oil in order to prevent oxide formation inside the machine.
7.
Connect the hose.
8.
Connect the pump to the system or equipment.
9.
Before operating the pump always make sure pipe connections are clean and fully tightened up; all
accessories have been fitted correctly: suction tube with nut and filter, pressure gauge and delivery hose for
high pressure (not included).
Always use protective goggles, shoes and gloves.
10.
Pre‐fill the system or equipment before starting the test with the same liquid that will be used for testing.
11.
To start the test, close the discharge valve (left) and open the flow‐valve (right) manually. There are two
handwheels on the control valve block for these two valves
.
12.
Now pump using the drive lever. The pump will come into operation taking the fluid from the tank below and
sending it to the system or equipment to be tested.
13.
Continue pumping to increase the pressure on the system.
14.
Check the pressure shown in the gauge and do not exceed the maximum pressure.
15.
Once reached the required pressure, close the flow‐valve, handwheel on the right, to maintain the same
pressure value in the element under pressure. Make sure there are no leaks.
16.
To finish the operation, open both valves and surplus liquid will run back into the tank via the drain hole in the
valve control block.
17.
To perform another test, follow the instructions from the beginning.
18.
Replace the seals at least every two years.
19.
If antioxidant additives are not used, is recommended to empty the tank every time is planned a period of
inactivity.
The pump must always be handled and repaired by qualified personnel.
Ensure that all the equipment and accessories are suitable
for the maximum working pressure.
