Chesterton’s New Pump Test Rigs

31 March 2020

A.W. Chesterton Company, a leader in pump sealing technology and solutions, has installed three pump rig stations for advanced testing of packing used in pumps, mixers, and agitators. The $85,000 investment allows the company to test all its rotary packing products and provide data for the relatively new industry standard: EN16752 Centrifugal Pumps - test procedure for seal packings. 

Chesterton will begin testing all of its existing rotary equipment packing according to EN16752 and begin making data available to its customers later in 2020. 
Each Chesterton simulated pump rig is equipped to monitor fluid pressure, gland and fluid temperature, power consumption, shaft speed, and leakage rate continuously via a digital data acquisition system. Each stand is fitted with a 15hp motor and variable speed drive to allow fine-tuning of shaft speeds for any configuration used. Leakage rates from the stuffing boxes are collected and measured automatically for the duration of the test.

To broaden the capability of the rigs beyond the parameters defined in EN16752, each unit in the Chesterton lab can be fitted with one of three interchangeable stuffing box modules to allow testing of different-sized cross-section of packings under a broad range of test conditions. The rigs can be used for limit testing pressures up to 500 psi and speeds of 5,000 rpm. They can be set in any combination below these limits, allowing for testing of application specific conditions or pushing packing performance limits.
