Hydraulic Ultra-High Pressure Test Pump User's Manual

[Version number:1306V01]

Operate the pump in the rated pressure range ,500 psi ,
DO NOT over the safety pressure 40,000 psi .

（

When the system pressure is greater than ,

the re-pressurization shut off valve（#7）

close p and then

（

37 ）

）

10,000 psi you must

pressurize the system.

Always tighten the gauges using two wrenches .
Close all valves and handles of the pump, and tighten the plugs

on the connectors during transportation.

Always keep the reservoir cover vent valve #4 open during

（ ）

operation.
Do not over tighten the valves, connectors and handles to avoid

any damage.
Change media immediately if it is contaminated.
Keep media level between 1/4 and 3/4 of the liquid reservoir filled.
Keep the threads clean and lubricious, and remove any dirt on

threads.
Used by Trained Personnel only.

Any security problems or damages caused by incorrect operations
are beyond Additel's responsibility.

Solutions

Close shut off valve (#1)

Open pre-pressurization shut off valve (#7)

Fill more media, and keep media level between 1/4 and 3/4 of the liquid reservoir filled

Turn the handle anticlockwise to vacuum the pump, open reservoir shut off valve (#1) to have air released

Close pre-pressurization shut off valve (#7)

Check connector, replace the PTFE type, re-tight using a wrench

Use proper adapter

Close pre-pressurization shut off valve (#7), open reservoir shut off valve (#1), turn pre-pressurization handle
(#9) clockwise fully, close reservoir shut off valve (#1), and then open pre-pressurization shut off valve (#7)

Step 1: Turn pre-pressurization handle (#9) clockwise fully, close pre-pressurization shut off valve (#7),

open reservoir shut off valve (#1).
Step 2: Turn pre-pressurization handle (#9) anticlockwise fully, close reservoir shut off valve (#1).
Step 3: Open pre-pressurization shut off valve (#7), pressurize the system.
Step 4: Repeat step 1 to 3.

Do not close shut off valves and handles too tightly

It is normal. Please use high-pressure pressurization handle to increase/reduce the pressure.

Lubricate the threads
