Do not overtighten packing. Run in a new set carefully, taking up on the gland nut a little
at a time. If the gland runs hot, it is generally a sign that the packing is too tight. Damage
to both shaft and packing will result. A properly packed and adjusted stuffing box will leak
perhaps 10 drops every 3 to 5 minutes
7. Significant Model Number
The significant model number stamped on the pump nameplate identifies the pump type,
the seal arrangement, and other details. Refer to the significant model number chart in
this manual if you are unsure of exactly what type of pump or seal you have.
Always refer to the full model number in any correspondence with your Eco distributor.
Drawings and a consolidated parts list for each Gearchem pump are included in this
manual. Recommended spare parts are denoted on the consolidated parts list.
