HIGH PERFORMANCE VANE PUMP INTERNAL LEAKAGE ( TYPICAL ) NOISE LEVEL ( TYPICAL ) VT7QDCB - B38-022-B10 Inlet pressure 0.9 bar abs Viscosity 32 cSt n = 1200 RPM n = 1800 RPM Lw= Lp + 8 db (A) Do not operate pump more than 5 seconds at any speed or viscosity if internal leakage is more than 50% of theoretical flow. Total leakage is the sum of each section loss at its operating conditions. Triple pump noise level is given with each section discharging at the pressure noted on the curve. HYDROMECHANICAL POWER LOSS (TYPICAL) PERMISSIBLE RADIAL LOAD Pressure in bar (psi) Total hydromechanical...
