Dimensions shown outside of brackets are metric units. FLUIDS Most premium grade petroleum base fluids can be used with W1200 pumps. Optimum operating viscosity is16-40 cSt (80-185 SSU). Minimum operating viscosity is 10 cSt (59 SSU) at maximum rated pressure and maximum rated speed. Maximum operating viscosity is 750 cSt (3409 SSU). Maximum cold start viscosity is 2000 cSt (9091 SSU). Contact Concentric for additional information regarding the W1200 performance using other fluids. TIME OPERATING TEMPERATURES Fluid temperature range: Mineral Oil Max. 93oC (200oF) continuous Max. 105oC (221oF) intermittent FILTRATION Proper filtration is critical to the trouble free operation of any hydraulic system. For optimumpump life ISO 4406/1986 (Code 18/14) is recommended. P1 - Continuous P2 - Intermittent Total cycle for P2 is 30 seconds. Above represents performance which can be expected from units incorporating flange port styles. INLET CONDITIONS Inlet vacuum should not exceed 0.35 Bar below atmospheric pressure (10 In.Hg.). Continuous operation at vacuums in excess of 0.2 Bar below atmospheric pressure (6 In.Hg.) are not recommended. Max. gauge pressure for pressurized inlet is 2.0 Bar (29 PSI). 20 SEC. MAX.
