HIGH PERFORMANCE VANE PUMP VT7QDCC INTERNAL LEAKAGE (TYPICAL) NOISE LEVEL (TYPICAL) VT7QDCC- B31-022-022 80 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. the pressure noted on the curve. PERMISSIBLE RADIAL LOAD Triple pump noise level is given with each section discharging at HYDROMECAHNICAL POWER LOSS (TYPICAL) Pressure in bar (psi) Total...
