HIGH PERFORMANCE VANE PUMP VT67EC Mounting W/connection variables INTERNAL LEAKAGE ( TYPICAL ) Seal class 4 - S4 (for fire resistant fluids) resistant fluids) Design letter Porting combination (see page BM-1-5) Direction of rotation (view on shaft end) NOISE LEVEL ( TYPICAL) 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 Double pump noise level is given with each section discharging at the pressure noted on the curve. HYDROMECHANICAL POWER LOSS (TYPICAL) Total hydromechanical power loss is the sum of each section PERMISSIBLE RADIAL LOAD Maximum permissible axial load Fa = 2000 N (449 Lbs)
