Installation Information FLUIDS - Most premium grade petroleum base fluids can be used with the D Series pump. Optimum operating viscosity is 16-63 cSt (80-288 SSU) at maximum rated speed. Minimum operating viscosity is 10 cSt (59 SSU). Maximum operating viscosity is 750 cSt (3409 SSU). Maximum cold start viscosity is 2000 cSt (9091 SSU). Contact Concentric for additional information regarding the D pump performance using other fluids.
OPERATING TEMPERATURES - Fluid temperature range (Mineral Oil): Max. 93oC (200oF) continuous and Max. 105oC (221oF) intermittent.
FILTRATION - Proper filtration is critical to the trouble free operating of any hydraulic system. For optimum pump life at maximum pressure ISO 4406/1986 (Code 18/14) is recommended. A 10-micron filter sized to accommodate full system return flow is recommended for most operating environments.
