Wallace and Tiernan Series 44 pump parts?

[Pump2005]

My plant has been running these W&T pumps since the plant opened in the late 70's. I am looking for a few dealers that carry replacement parts for these pumps. Anyone still use these pumps?

W&T was bought by Pulsafeeder, most parts are still available and cross reference lists are available
usabluebook and many other suppliers carry pulsafeeder
