Volume Compressor vs Grease Pump

The Volume pump put out more greese per stroke and less presure as your reg. grease gun puts out high presure low volume. The reason is so you don't blow tyhe old leather seals out of the rollers. They range from $75 for late type to the hundreds for early 3 legged type with Best or Holt on them and evrything between. How many do you wanna buy?

Actually looking at the viscosity of 00 grease, it seems an "oil pump" would do the trick. It also would apply less pressure. For example, a Zeeline #321. (http://www.zeeline.com/Products/OilEquipment/Pumps/OilPumpsManual/default.aspx) It looks like the 321 is less pressure as well.

Willie, I only want to buy 1. Where would I find a $75 dollar one? Who makes it? Can I buy it online? (I've done some initial searches and haven't gotten anywhere.) As often as I plan on doing this (I've got one D6 that needs it, and I don't put many hours on it), spending hundreds on it is unreasonable.

I picked up two of the late model similiar to the one on the right in the photo. Are they rebuildable as far as the pump piston and packing?
Thanks!

There is a relief valve available to put on the zerk and then the pump hooks to it and limits the pressure to rollers and idlers so you don,t blow the seals. I can,t remember what brand they were but could have been Alemite. We had one at the dealer to use.

Ill sell you the one one the right in pic and you can buy them new from alimite there are whaite and red not the pretty yellow like mine

Willie, I tried sending you a private message, but your mailbox is full.
