A pump comprises a shaft (4), two opposed swash plates (2,3) carried by the shaft (4), and at least one plunger (9, 10, 11, 12) disposed between the swash plates (2, 3). The swash plates (2, 3) are rotatable with the shaft (4) about a longitudinal axis of the shaft (4) for driving the or each plunger (9, 10, 11, 12), the arrangement being such that forces exerted on the swash plates (2, 3) by the or each plunger (9, 10, 11, 12) during operation of the pump are mutually opposed so as to reduce the net axial force on the shaft (4).
