256148 — Chief V20 Vane Pump, 1.81 CID, 9 GPM, CW, 2 Bolt A
KKM Solutions is an independent parts distributor, not an authorized Chief dealer — how we source.
Overview
Part number 256148 from Chief, listed in Hydraulic Pumps & Power Units. Specifications on file: Cubic Inch Displ. (CID) 1.81; Flange O.D. 4.19 center to center bolt; GPM 19.7 Max; Inlet Port 1 1/4 NPT. KKM Solutions quotes this part with pricing and availability confirmed per order.
Features:
High flow, pressure, and speed capabilities enable these pumps to meet the needs of modern vehicle hydraulic circuits.
Optional flow control and priority valve covers offer even more versatility.
The superior design of these units makes them last longer.
They’ve proven they’ll hold up in rugged applications such as trenchers, backhoes, and tractors.
Internal inlet and outlet pressure chambers are diametrically opposed.
As a result, pressure-induced radial loads are balanced, so bearings only carry the external load.
Low vane tip/ring loading allows high-pressure operation.
High speeds are possible because the inlet flow paths are designed to give uniform oil acceleration, ensuring better filling—particularly at low inlet pressures.
