HG561 FABRICATED SLIDE GATE
Maintenance
Removal of the stem nuts for
thread inspection or check with
the wear checking procedure of
frequently modulated gates is
recommended.
Lubrication Equivalents
We consider any of the following
greases/lubricants to be acceptable:
• Fiske Brothers “Lubriplate” No.
630 AAA or AA
• Sta-Lube “Sta-Lube” No. 3121
• Conoco “All Purpose Superlube”
• Texaco “Multi Fak Heavy Duty”
No. 2
• Shell Gadus Grease (formerly
known as Alvania)
• Mobil “Mobilux EP2"
• BP Energrease LS 2
Replacement or spare nuts
can be ordered from us. Spare
parts are usually not needed or
recommended, because they are
readily available on short notice
We recommend the following pipe
thread sealants with Teflon:
• La-Co Slic-Tite Paste
• Dayton Pipe Thread Sealant with
Teflon
• McMaster-Carr Pipe Thread
Sealant with Teflon
• Any other commercially available
pipe thread sealants containing
Teflon
from us. In those cases where
equipment operation or downtime
is critical and the gate is operated
extremely often, a spare lift nut
may be pertinent to
have on hand.
For potable water treatment plants,
we recommends using a vegetable-
based lubricant such as:
• Lubriplate Super FML-2
• Rocol Foodlube Multi-Paste
(European product)
• Petro-Canada Purity-FG
