Description

The Rola-Chem 525113 is a 7/16 inch crane washer listed as a replacement part for the Rola-Chem Pro Series 300 pump.

Ordering the right one

Feeder washers are hard to identify once they are out of the machine, and close sizes are easy to confuse. Match the part number, 525113, and the 7/16 inch size rather than comparing the old part by eye.

Worth stocking

Small sealing parts on a chemical feed pump are consumable. They harden, flatten and eventually weep, and the pump is usually needed on the day the leak appears. Owners commonly pick up the 7/16 inch plastic injection fitting for tube for the same pump at the same time, which is ordered separately.
