T-900 Series Pump Operation Manual
Overview
Overview
 INTRODUCTION
The T-900 Series calibration hand pump, designed by Mansfield & Green, generates pressure for verifying, adjusting and calibrating mechanical and electronic
pressure measurement devices.
This hand pump is suitable for pressure tests in laboratory and field settings.
The T-900 Series calibration hand pump is easy to operate and allows for precise pressure generation. Combination models include a shuttle valve to allow vacuum
generation as well. CPFversions include Crystal Pressure Fittings (CPF), which allow users to produce leak-free seals without tools or thread tape. CPF fittings also
include a self-venting weep hole to help assure a safe disconnection from a pressurized system.
U.S. Patent No. 8,794,677
The T-900 Series calibration hand pump may be ordered as part of a Pump System, complete with a JOFRA or Crystal Pressure Indicator. T-900 Series Pump Systems
include the most commonly used pressure fittings, seals, etc. All packaged in a carrying case with custom insert.

T-900 Series Pump Operation Manual
Device-Under-Test Pressure Port Connections
In order to adapt the different connection threads of the device-under-test, the pressure hose can be fitted with different adapters. Please use a suitable sealing
gasket or Teflon tape as applicable for the thread type.
! CAUTION: Do not use teflon tape with BSP or CPF threads; this may damage your hand pump.
! CAUTION: The T-900 Series hand pump must not be soiled, or come into contact with fluids or aggressive media.
! CAUTION: To prevent leaks, tighten the tube fitting or CPF connection to a maximum torque of 15 N-m = 11 lb-ft.

Actuate the Shuttle Valve (Combination Models Only)
Verify that the shuttle valve is positioned to provide pressure or vacuum. Use a pen or a small screwdriver for this purpose.
The encasement of the switch is intended to help prevent unintentional actuation. (Only applies to models T-965, T-975, and T-975-CPF.)
Operating and Safety Instructions 6
GENERATING PRESSURE AND VACUUM

T-900 Series Pump Operation Manual
! CAUTION: Never actuate the shuttle valve while the hand pump is under pressure or vacuum. Actuate the shuttle valve only when the pump is
vented.
Apply Pressure or Vacuum
1Verify that the vent valve is open.
2For positive pressure, turn the fine adjustment knob to the full, counter-clockwise position. For vacuum, turn the fine adjustment knob to the full, clockwise
position.
Operating and Safety Instructions
3Zero your reference indicator.
4Close the vent valve.
To apply pressure...

T-900 Series Pump Operation Manual
5Operate the hand pump until the target pressure is nearly reached, but no more than 25 bar (for T-970, T-975, and T-975-CPF) or 1.5 bar (for T-960 and T-965).
6Turn the fine adjustment valve to reach the target pressure, as indicated on the reference indicator.
Note: After increasing pressure, the reading may drop slightly. This is due to thermodynamic or adiabatic effects , hose expansion, and sealing gaskets. If
pressure does not stabilize, check the measuring circuit for tightness.
Note: Due to the low volume of each compression stroke of the hand pump, only small volume instruments should be tested.
To apply vacuum...
5Turn the fine adjust valve counter-clockwise to generate a first vacuum.
6Operate the hand pump smoothly and slowly to reach the target pressure.
Note: After decreasing pressure, the reading may increase slightly. This is due to thermodynamic or adiabatic effects , hose expansion, and sealing gaskets. If
pressure does not stabilize, check the measuring circuit for tightness.
Note: Due to the low volume of each compression stroke of the hand pump, only small volume instruments should be tested.
! WARNING: Never connect an external pressure supply to the pump.
Relieve Pressure or Vacuum
Relieve pressure by carefully opening the vent valve.
! WARNING: Remove the reference indicator or the device-under-test only once the vent valve is open and no pressure is applied to the hand pump.
Adjustable Stroke
The T-900 Series hand pumps include a stroke adjustment in order to reduce the risk of overpressure. The knurled nut is used to set the lift stop. A shorter travel will
generate less pressure per stroke; a longer travel will generate more pressure per stroke.
Set the lift stop with the knurled nut.

 TROUBLESHOOTING
Unstable Pressure or Vacuum
Problem: Pressure or vacuum cannot be generated correctly, or set pressure or vacuum does not remain stable.
Solution: If the problem persists after allowing time for thermodynamic effects to stabilize, this is likely to be caused by the incorrectly positioned or selected
sealing gaskets. Also check that all adapters and pressure fittings have been tightened sufficiently to eliminate leaks.
Pressure or Vacuum is not Maintained
Problem: The hand pump appears to leak.
Solution: (1) Check that the vent valve is completely closed.
(2) Check that the shuttle valve switch is correctly positioned and is not in a “center position” (if a combination model).
(3) Verify that all the connection fittings are firmly tightened and properly sealed.
Pumping Action Appears Sluggish
Problem: The first lift of the pump is somewhat sluggish.
Solution: The hand pump has not been used for a longer period of time. This effect will disappear as the pump is operated.
