Pressure gauge comparison pumps (data sheet 10 925)
We supply pressure gauge comparison pumps for liquid media also mounted into a case similar to a case for dead weight testers (code letter –G).
A spindle pump with star handle serves to build up the pressure and to regulate the test pressure. The test instrument and the specimen gauge are connected to the comparison pump with stop valves via clamping sleeves.
Comparison pumps in a case are better suited for continuous operations, e.g. in test shops, than those mounted on a plate. The case versions are also provided with filters to avoid contamination of the pump pipe system.
We recommend to supply external compressed air up to max. 10 bar for a quick and easy filling of the system. As special versions with oxygen the instruments are available up to a maximum pressure of 1,000 bar.
