TypeT Pump Operation Manual
Overview
INTRODUCTION
The Type T Series hand pump, mounted on a drip pan with a manifold assembly, is capable of producing pressures up to 1000 bar/15 000 psi.
These units are self-contained pressure sources designed to test instruments. They may be used to calibrate pressure gauges or to set hydraulic relief valves
and pressure switches. These units produce pressure to test components or systems, and work independently of other pressure sources. CPFversions include
Crystal Pressure Fittings (CPF), which allow users to produce leak-free seals without tools or thread tape. CPF ttings also include a self-venting weep hole to
help assure a safe disconnection from a pressurized system.
U.S. Patent No. 8,794,677
T, T-1, and T-2 pumps1may be ordered as part of a Pump System, complete with a JOFRA or Crystal Pressure Indicator. T-3 pumps ship as part of a complete
comparator testing kit, including four analog test gauges and necessary mounting tools and ttings, all housed in a rugged metal carrying case. For more
details on T-3 comparator testing kits, refer to T-3 Pumps for Hydraulic Comparator Kits on page 2.
All Type T Series Pump Systems include the most commonly used pressure ttings, seals, etc., all packaged in a carrying case with a custom insert.

Safety Instructions 6
TypeT Pump Operation Manual
Safety Instructions
WARNINGS, CAUTIONS, AND NOTES
! WARNINGS:
• Do not connect any external pressure source to this instrument. This unit is designed to test pressure measuring devices connected to the manifold
only. Pressure from an external source can result in explosion of the liquid reservoir and possible bodily injury.
• This pump produces pressure up to 15 000 psi. The pressure rating of tubing and ttings used to connect the pump to the test device should exceed
15 000 psi.
• Do not operate above 15 000 psi/1000 bar.
! CAUTIONS:
• To prevent the reservoir from overowing upon venting, the volume of oil pumped should never exceed the reservoir volume.
• Never operate the pump without uid in the reservoir. The piston and o-rings require lubrication.
• Do not operate the ne adjust knob above 3500 psi.
• The vent plug must be open to operate this instrument.
Notes: All wetted parts are stainless steel, Monel, or Buna-N. Optional o-ring materials are Viton and EPT .

3 Close the vent valve.
Note: If using the T-1-CPF, ll with test uid through the gauge connections. This may take approximately 15 minutes.
Note: It may be necessary to prime the pump, particularly for rst time use, or if the pump has been inactive for an extended period of time.
Refer to Priming on page 10 for instructions on priming the pump.
4Pull the pump handle to the top of its stroke.
5 Pull out the valve rod selector to select the low pressure/high volume setting.
6 Gently operate the pump handle until test uid lls the top of the pressure ports on the pressure manifold.
Note: Lightly tap the manifold to make sure that any air bubbles sticking to the walls or in low ow areas are released to oat to the surface.
7 Attach the reference instrument and the device under test to the manifold.
Note: If CPF Fittings are used in your pressure system, remaining air can be purged by applying 10 psi or less and loosening the CPF tting closest to the pres-
sure device. When uid and air escape from the CPF weep hole, that portion of the system is purged. Repeat this process for each pressure device in the
pressure system which is connected to a CPF tting.
! CAUTION: Always choose a reference instrument with a range equal to or greater than the range of the device under test.
8 Ensure all connections are tight and leak free.

4 Zero the reference indicator and the device under test.
5 Close the vent valve.
6 Operate the pump handle to achieve a system pressure close to, but less than, your desired target pressure.
7 Pull the pump handle to the top of its stroke.
8 Push in the valve rod selector to select the high pressure/low volume setting.
9 Wait for the pressure to stabilize.
10 Carefully push down the pump handle to achieve the target pressure.
Note: Below 3500 psi, you may also use the ne adjust knob for small pressure adjustments.
11 After obtaining your readings, open the vent valve to vent the system.
! WARNING: The device under test and the reference indicator should only be removed when there is no pressure in the system.
PRIMING
All pumps are thoroughly tested at the factory before shipment. One of the most common diculties encountered is the loss of prime, which is evidenced by
an inability to build pressure. This is caused by entrapped air in the reservoir, which may collect in the high pressure/low volume check valve. When this oc-
curs, the pump will not develop pressure with the valve rod selector positioned in, to the high pressure/low volume setting. The following priming procedure
will correct the condition.
Note: For priming purposes, pump vigorously with full strokes of the hand lever.
Note: Verify the pump reservoir has sucient uid.
X
To Prime the Pump
1 Connect a reference indicator with a pressure range of at least 5000 psi to the manifold.
! CAUTION: Signicant pressure can develop during the priming process. Therefore, any device mounted to the manifold should have a range of at least
300 bar / 5000 psi. Alternately, all devices may be removed, and the manifold plugged.
2 Plug the remaining port of the manifold.
Manifold Plug

Operation and Maintenance 11
TypeT Pump Operation Manual
3 Pull the pump handle to the top of its stroke.
4 Open the vent valve.
5 Pull out the valve rod selector to select low pressure/high volume.
Open the vent valve… then select low pressure/high volume.
6 Pump ten full strokes.
7 Close the vent valve
8 Continue pumping to verify the low pressure/high volume setting operates properly and that the pump holds pressure.
9 Open the vent valve.
10 Pump ten more strokes.
11 Remove the high pressure/low volume check valve plug.

Operation and Maintenance 12
TypeT Pump Operation Manual
12 Slowly pump two and one-half strokes, positioning the pump lever at approximately 45 degrees, halfway through its stroke.
13 Allow system uid to ow out of the high pressure check valve, ushing entrapped air.
14 Examine the port for air bubbles which may adhere to the threads or parts.
Note: If air bubbles are present, repeat steps 12 through 14 until no more air bubbles appear.
15 Replace the high pressure/low volume check valve plug and tighten partially.
16 Use slight pressure on the hand lever to push system uid past the high pressure/low volume check valve plug to ensure complete purging of the
valve port.
17 Tighten the high pressure/low volume check valve plug.
18 Operate the pump handle until pumping becomes dicult.
19 Raise the pump handle.
20 Push in the valve rod selector to the high pressure/low volume position.
21 Resume pumping to verify the pump is operating properly.
Note: If the high pressure/low volume setting does not operate properly, there is more air trapped in the high pressure/low volume check valve. The priming
procedure must be repeated.
