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.
