Faster pump seal changes put to the test
Howard Hall of Andrew Reid & Partners shows how to change a pump seal in just 18 min 45 s. He won a competition at the recent London Hevar exhibition to change the seal on an Armstrong Holden Brook Pullen 4300 pump, earning for himself a DAB digital radio. Other fast workers were Chris Barrett and Remy Suzan of Gratte Bros at 18 min 47 s and 18 min 48 s, respectively. A key benefit of this model of Armstrong pump is the external sealing arrange, which contributes to the long life of the seal and makes routine maintenance far quicker and easier. The multi-spring balanced seal has a split coupling that enables all seal components to be withdrawn for servicing without the need to disturb other pump components or the motor connection.
