PARSIPPANY, NJ – The Hydraulic Institute (HI) has released a new test standard, ANSI/HI 7.6 Controlled-Volume Metering Pumps for Test, for testing positive displacement reciprocating controlled-volume metering pumps. The standard provides uniform procedures for hydrodynamic controlled-volume pump performance testing and for recording of the test results of metering pumps.

The following types of tests are covered in the 2012 edition of the standard: functional testing of production units, mechanical integrity at speed and pressure specified, rate of flow and mechanical integrity at speed and pressure specified, and verification of performance to the manufacturer's specifications.
