Application
The LSM-6F can be used with all products that
are compatible with the materials of
construction and seal material.

Pressure Rating
Atmospheric pressure up to 2160 psi (149 Bar)
or as determined by flange rating. Higher
pressure ratings available.

Temperature Rating
From -20 to +250 °F (-29 to + 121 °C).

Viscosity
All fluid ranges.

Sample Size
Vanishing Chamber standard sizes are as
follows: 0.2cc, 0.5cc, 1.0cc and 1.5cc.
"B" Head piston style optional sizes are as
follows: 0.5cc, 1.0cc, 2.0cc, 3.0cc, and
4.0cc.
"D" Head piston style optional sizes are as
follows: 3-7cc and 5-12cc.

Sampler Actuation
Double or single acting piston motor rated at
120 psi (8 Bar). Both actuating and release
time should be 2 seconds minimum. Sampler
actuation can be either time or flow
proportional.

Materials
Lubricator body and piston motor are
constructed of carbon steel, balance 316
stainless steel with Viton, PTFE and Fluorotrel
seals.

Connections
All instrument connections are 1/4'' FNPT.
Pipeline - 2" 150 ANSI RF standard.

Required Utilities
Instrument air 60 to 120 psi (4 to 8 Bar)
dependent on line pressure. Air consumption
