Frequently Asked Questions
Will this seal kit fit my Vickers 3525VQ35A21S 111AA 21?
It is matched to the 3525VQ35A21S 111AA 21 model code, assembly number 579790-1, using the Vickers 3525VQ 20-design service data, keyed on the double shaft seal build. Pumps built for equipment makers can use a different seal set, so check the full code on your nameplate, including anything after the last letter, and ask us if it differs.
How do I get a price and lead time?
Send the model code from your nameplate through our quote form, or email info@restopower.com. We reply with the matched kit, price, availability and lead time.
Which seal material do I need?
Buna-N (nitrile) is the standard choice for petroleum based hydraulic oil. Viton (FKM) is available for higher operating temperatures. It is not rated for phosphate ester fluids such as Skydrol, which need a different seal compound.
