Special Information
INTRODUCTION:
PHP-10/20/25/35/40/60 bar hand pump is a pneumatic pressure / vacuum generating
unit which are specially designed for testing and calibrating pressure instruments. This
pump is manufactured with high quality for calibrating analog gauges by comparison
measurements. It can be used for lab and field applications.
There is a pressure / vacuum changeover switch in the pump, which is used for
selecting either vacuum or pressure output. It is fitted with a fine adjustment valve and
release valve. The output pressure / vacuum of the hand pump can be adjusted
precisely by the fine adjustment valve while calibration. Release valve is used for
releasing the pressure / vacuum after calibration. The output pressure /vacuum of the
pump is in the range of -0.90 to 10/20/25/35/40/60 bar depending upon the model.

CERTIFICATION:
Mechatron certifies that this pump is a quality product and meets its intended use and
satisfies the published specification at the time of shipment.
TECHNICAL ASSISTANCE:
Please contact Mechatron if you require any technical assistance.
WARRANTY:
One year warranty
This warranty only covers manufacturing defects and becomes invalid if the pump is
subjected to unauthorized intervention and / or use.
FEATURES:
Portable | Light in weight | Low Cost | Rugged Construction
SAFETY INSTRUCTIONS:
1.
➢Check for system fittings and connection tight and leak free.
➢Tighten the pressure release valve fully to ensure good sealing.
➢70% of the pressure / vacuum are to be given using handle and the
remaining 30% is to be given using adjustment valve.
➢Do not attempt to over tighten the other fittings to the pump as this could
lead to damage of sealed joints.
➢Release pressure / vacuum before changing the mode by pressure /
vacuum selector.
➢Do not connect pump to external pressure source

2.
The connections to the hand held test system are sealed with ‘O’ ring, bonded seals
& Nylon washer to avoid leak.
Ensure that the adapters are tightened sufficiently.
Allow the pressure to settle for 1-2 minutes before taking the reading due to
thermodynamic effect, setting of seals and expansion of flexible hose.
3.
Red line indicator
The Fine adjustment should not be forced to move beyond the red
line indicator on the body

FUNCTIONAL DESCRIPTION:
Pressure Release Valve (3)
This can be used to reduce or release the pressure in the system. Minimal force is
required to seal the system
Fine Adjustment Vave (4)
The Pressure generated can be finely adjusted by turning the fine adjustment valve
(4) either clockwise or anticlockwise to increase or decrease pressure accordingly.
Pressure / vacuum Selector (5)
Press the selector (5) as indicated on the label to engage the desired mode. Ensure
that the release valve (3) is closed firmly (clockwise motion) prior to pumping.
Knurling Thumb Nut (2) (Over pressure protection)
To adjust the maximum output pressure of the system turns the knurling thumb nuts
(2) to increase or decrease the stroke length so that the pressure is controlled.
4.0 OPERATING PROCEDURE
➢Connect the master / test instrument using the appropriate adapter and seals to
the pressure port at the end of the flexible hose (6) or directly to the body (10)
using appropriate adaptor
➢Open the fine adjustment valve (4) in the anticlockwise direction until red mark
appears
➢Ensure the pressure release valve (3) needle tightened in the clockwise direction.
➢Pressure / vacuum calibration can be selected by Pressure / vacuum selector (5).
➢Generate pressure / vacuum by squeezing handles (1) together. Ensure that the
handles are fully squeezed together on each stroke to achieve maximum
pressure / vacuum output.

➢The output pressure / vacuum can be adjusted with the fine adjustment valve (4)
for a precise pressure / vacuum adjustment.
➢After the calibration, completely release the pressure / vacuum by twist off the
vent-valve (Release valve) gradually in anticlockwise direction.
➢Take out the master and the test instrument from the pump.
