Small-sized hydraulic-pneumatic pump «PGM»
sssGenerating of test pressure and vacuum for calibrating measuring instruments in the field and in laboratory conditions.
Advantages
Compact design suitable for field applications. Much lower weight as compared to analogues (4.8 kg).
Convenient and easy mounting both in stationary position (on table) and in the field conditions (on pipe, guarding).
Working medium diversity: oil, water, alcohol, air. Leak-tight bowl for working fluid enables transportation in filled and ready-to-operation condition.

Equipping PGM with digital standard manometers DM5002M-A allows using it as a standard instrument for manometers calibrating.
- Multi-range feature: each digital manometer DM5002M-A features several switchable measurement sub-ranges with assuring the same accuracy class in each sub-range. Due to this feature one manometer DM5002M-A can replace four pointer gauge manometers.
- Switching between different units of measurement: MPa, kgf/cm², one more — optional: psi, mm Hg, etc.
- High accuracy class: 0.25; 0.15; 0.1 и 0.06.
