High Pressure Hydraulic Test Pump
Instructions
Introduction
The 730HTP70M High Pressure Hydraulic Test Pump (the Product) is
used to check pressure measurement devices against master reference
gauges. The Product supplies the same pressure to both a reference
gauge and a device under test (DUT) to test the accuracy of the DUT.

Before Use
To fill the tank:
1. Turn , injection screw, counterclockwise to remove the injection screw I
from the injection port.
2. Pour oil or water into the tank up to the bottom of the inject port. Use
a funnel if needed.
3. Place an O ring on the filter plug if needed.
4. Turn I, injection screw, clockwise to tighten the the injection screw
into the injection port. Do not overtighten.
5. Turn E, vent valve, counterclockwise to exhaust the air from the oil or
water.
Operation
Zero the Product before you do a pressure test.
Zero the Product
To zero the Product:
1. Turn , pressure release valve, counterclockwise until the valve is fully C
open.
2. Turn G, pressure maintaining valve, counterclockwise until the valve is
fully open.
3. Turn A, fine adjustment wheel, to the middle position.
4. Put one O ring in each of the output ports.
5. Connect the reference gauge to D F, output port 1 or , output port 2.
6. Connect the DUT to the open output port.
7. Read the zero pressure from the reference gauge.
8. Turn C, pressure release valve, clockwise until the valve is fully closed.
Ascending Pressure
To check ascending pressure:
1. Zero the Product.
2. Turn C, pressure release valve, counterclockwise until the valve is fully
open.
3. Turn G, pressure maintaining valve, counterclockwise halfway.
4. To generate pressure, lift B, pressure handle, up and down until the
pressure gets close to the target pressure. If liquid comes out of an
output port, remove and reconnect the reference gauge or the DUT.
5. Turn G, pressure maintaining valve, clockwise until the valve is almost
closed.
6. To get to the target pressure, turn A, fine adjustment wheel, to
increase or decrease pressure as needed.
7. Turn G, pressure maintaining valve, clockwise until the valve is fully
closed.
8. Turn C, pressure release valve, clockwise until the valve is fully closed.
9. Record the pressure from the DUT.
10. Repeat for each target pressure point up to the full scale.
Descending Pressure
To check descending pressure:
1. Zero the Product.
2. Turn G, pressure maintaining valve, counterclockwise halfway.
3. Generate ascending pressure greater than the target pressure or up to
the full scale.
4. Turn G, pressure maintaining valve, clockwise until the valve is almost
closed.
5. Select a pressure status:
●High pressure:
Turn A, fine adjustment wheel, counterclockwise until the
pressure gets close to the target pressure.
●Low pressure:
Lift B, pressure handle, up and down until the pressure gets close
to the target pressure.
Troubleshoot the Product
If the Product does not function as expected, try the steps in Table 3.
Table 3. Troubleshoot the Product
Problem Cause Solution
Difficult to maintain
pressure (leakage)
The pressure release valve is open. Close the pressure release valve.
The reference gauge is loose. Tighten the reference gauge.
The DUT is loose. Tighten the DUT.
An O ring is worn. Replace the O ring.
The threads on the Product, the reference gauge, or the
DUT are not smooth.
Apply thread seal tape to the threads of the reference gauge and the
threads of the DUT.
An impurity blocks the circulation of air. Repeatedly apply pressure and suddenly release the pressure until the
impurity comes out.
The DUT connector is too small for the output port on
the Product. Use an adaptor to connect the DUT to the Product.
Difficult to generate
pressure
The pressure maintaining valve is closed. Open the pressure mantaining valve.
The pressure release valve is open. Close the pressure release valve.
The reference gauge is loose. Tighten the reference gauge.
The DUT is loose. Tighten the DUT.
An O ring is worn. Replace the O ring.
The tank is empty. Fill the tank.
There is a leak in the DUT. Test another DUT.
There is air in the system.
1. Put a plug in each output port.
2. Close the pressure release valve.
3. Generate pressure.
4. Open the pressure release value.
5. Repeat as needed.
Valves or wheels do
not turn freely.
The valve or wheel is turned too tightly. Firmly grasp the valve or wheel and turn it gently.
The threads of the Product are dry. Apply grease to the threads of the Product.
6. Turn G, pressure maintaining valve, clockwise until the valve is fully
closed.
7. Record the pressure from the DUT.
8. Repeat for each target pressure point down to zero.
