1. INTRODUCTION
Nagman’s calibration hand pump is designed to manually
generate pressure between -0.90 upto 10/25/35/40 bar
(depending upon models) of vacuum and pressure for quick
and accurate calibration of pressure gauges and other
pressure measuring Instruments.
This pump is manufactured with high quality components for
calibrating Analog / Digital gauges by comparison method. 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 a 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:
-0.9 vacuum to 10 / 20 / 25 / 35 / 40 bar pressure depending
upon the model.

5. FUNCTIONAL DESCRIPTION
Pressure Release Valve (3):
Used to reduce or release the vacuum /
pressure in the system. Minimal force is
required to seal the system.
Fine Adjustment Valve (4):
The vacuum / pressure can be finely adjusted
by turning this fine adjustment valve either
clockwise or anticlockwise to increase or
decrease pressure accordingly.
Pressure or Vacuum Selector (5):
Press the selector as indicated in Figure 1 to
engage the desired mode. Ensure that the
release valve is closed firmly (clockwise
motion) prior to pumping.
Knurling Thumb Nut (2) (Over Pressure
Protection):
To adjust maximum output pressure of the
pump turn the knurling thumb nuts (2) to
increase or decrease the stroke length so
that the maximum pressure is controlled per
stroke.
