Giant Headache; Giant Problem

[Mr. Clean]

Four of six of my 8 yr. old German made pumps have blown out oil seals in the last month. Has anyone else had a similar experience? Is this a regular PM item. Only the pressure seals have been changed to date. Is it worhtwhile to rebuild?

Using another brand at different location and have not experienced this problem in almost 20years.

Thanks.

Switch to Arimitsu and don't look back.. the 313 is great for ss

Changing oil seals is relatively simple and inexpensive on plunger pumps. Is that what you have?

 

[Mr. Clean]

Yes, they're plunger pumps, model 56W. Probably not worth the expense of sending out, so I may tackle one and see how it goes.

What are the attributes of Arimitsu?

I'd dump the Giant pump faster than you can say Giant pumps

The Arimitsu pumps are:
There easier to service
They have a better warranty
They are quieter
They withstand head washout better than most other pumps
They are less expensive than the other pumps

There may be a common cause with having so many pumps with the same problem in such a short time, like maybe an employee filling the crankcase to the top with oil instead of to the proper level, or even swapping out a bad pump with a repaired one and not replacing the top plug with the breather/dipstick.

When you change the piston oil seals, you'll also need to replace the seals on the plunger bolts.

What about the cat pumps after the heads have been done with stainless, we have several in service but not long enough to tell!

I've never had a Cat pump head wash out. I've replaced lot of them at other washes. But not at my wash.

I'd get rid of the Giant pumps, there a Giant pain in the @@@
