Dark Light

WS Series



  • Separates contaminants and water simultaneously.
  • Glass compartment for a visual instant check for water separation progress.
  • Water drainage outside of the working line.
  • Simply use as a fine contamination filtration unit with or without water contamination.
  • Easy maintenance.

This separates is composed of suction-strainer, Trochoid pump, Pre-filtration element which removes soft agents such as contaminants and depleted agents as well as makes water particles aggregate together, and Water Separation filter inserted in WS housing. The lower part of WS housing is made of clear acrylic resin, so that you can observe the water separation degree at a glance. The drain valve affixed on WS housing is to drain the separated water.

Water Separation Efficiency of WS-WD
Example: The contamination with grinding water and sludge is observed in hydraulic oil at the grinder.

Application: ******* grinding machine G-1981 90 lit Daphne Super Multi-oil 32

Sampling date 12 Dec. 1997 22 Dec. 1997 07 Jan. 1998 27 Jan. 1998
NAS grade over 12 over 12 over 12 5
W.C.D. 2.6 1.3 0.6 0.5
Moisture 7,538 8,082 664 143
K. Viscosity 32.23 31.16 31.85 31.76
T. A. N. 0.54 0.42 0.41 0.40


Parenthetically, the reason why NAS grade before 27 Jan. 1998 was as bad as over12 is that a particle counter (analysis equipment) counted extremely many water particles.
