A radial piston pump comprising a rotor mounted for rotation on a pintle. The rotor comprises a plurality of piston chambers, a piston being mounted in each of said chambers for reciprocal movement. The pump comprises a supply flow path which connects the piston chambers to a supply of low-pressure fluid, an exit flow path via which high-pressure fluid from the piston chambers leaves the pump, and an auxiliary flow path which connects another component of the pump to the piston chambers. The pintle comprises a plurality of flow galleries comprising a supply flow gallery forming part of the supply flow path, an exit flow gallery forming part of the exit flow path, and an auxiliary flow gallery forming part of the auxiliary flow path. The radial piston pump uses the pintle as a fluid manifold providing fluid to or from the pistons.
