2 THRU-DRIVE HYDRAULIC VANE PUMPS “TQ/TV” SERIES Thru-drive pumps save installation space and cost by eliminating double shaft extension electric motors or by reducing the number of motors and drive couplings. Furthermore thru-drive models provide valuable circuit design flexibility, such as having the vane pump coupled with other types of pumps, both fixed and variable displacement, on a single input drive. The B&C thru-drive pumps are available in TQ and TV versions. The ten vane TQ type is particularly suitable for applications subject to sudden peaks of pressure, while the twelve vane TV model is specifically designed to meet very low noise requirements. The table below shows the main technical characteristics of both TQ and TV versions. More detailed technical information is available on the catalogues of the standard BQ and BV pumps. cm3/g (in3/r) l/min (gpm) bar (psi) rpm bar (psi) rpm 40,1 (2.45) 46,9 (12) 210 (3050) 2700 175 (2538) 1800 45,4 (2.77) 52,7 (14) 210 (3050) 2700 175 (2538) 1800 55,2 (3.37) 64,2 (17) 210 (3050) 2500 175 (2538) 1800 60,0 (3.66) 71,0 (19) 210 (3050) 2500 175 (2538) 1800 67,5 (4.12) 79,0 (21) 210 (3050) 2500 175 (2538) 1800 69,0 (4.2) 79,5 (21) 210 (3050) 2500 175 (2538) 1800 81,6 (5) 94,0 (25) 210 (3050) 2500 175 (2538) 1800 97,7 (6) 113,8 (30) 210 (3050) 2500 175 (2538) 1800 112,7 (6.9) 131,6 (35) 210 (3050) 2400 175 (2538) 1800 121,6 (7.4) 139,9 (38) 210 (3050) 2400 175 (2538) 1800 138,6 (8.46) 164 (42) 175 (2538) 2200 175 (2538) 1800 153,5 (9.4) 180 (47) 175 (2538) 2200 175 (2538) 1800 162,2 (9.9) 189 (50) 175 (2538) 2200 175 (2538) 1800 183,4 (11.2) 217 (57) 175 (2538) 2200 175 (2538) 1800 193,4 (11.8) 230 (60) 175 (2538) 2200 175 (2538) 1800 TQ series TV series Maximum pressure Max Maximum pressure Max with mineral oil speed with mineral oil speed Pump Geometric Rated capacity type displacement at 1200 rpm 7 bar 02 04 05 Technical characteristics oil viscosity: 25 c.St. (10W), temperature: 45°C, inlet pressure: 0 BAR TQ/TV
