 Note: Theoretical pump delivery in gpm (l/min) is determined by multiplying displacement (cm3/rev) by desired pump rpm and dividing by 231 (1000). |
| QCC YC Series hydraulic gear pumps are ideally suited for applications where a lightweight, compact, and efficient pump is needed. Operating at continuous pressures to 2500 psi (172 bar) and speeds to 3000 rpm, YC Series pumps are available in displacements from .58 to 1.94 in3/rev (9,5 to 31,8 cm3/rev).
YC pumps have a pressure balanced design for high volumetric and mechanical efficiencies. They feature two-piece, high-strength aluminum alloy construction with heat-treated alloy steel gears and shafts. Standard features include straight, keyed shaft; heavy-duty sleeve bearings; double lip, nitrile rubber seal; and side SAE O-ring or NPTF type ports. Optional flow dividers are available with factory preset constant delivery from 1 to 9 gpm (3,7 to 34 l/min) at the regulated flow port.
