A fluid pump (20) comprises a dispenser body (22), closure cap (54), seal assembly (34), and priming check valve (88). The dispenser body (22) has a pump (24), discharge port (102), and a discharge path (76). The closure cap (54) is connected to the dispenser body (22) and closes the mouth of the container (56). A first portion (60) of seal assembly (34) prevents leakage between closure cap (54) and the mouth of the container (56) when the closur e cap (54) closes the mouth of the container (56). A second portion (62) of th e seal assembly (34) has an intake port (78) for fluid communication with liqu id in the container (56). The second portion (62) and dispenser body (22) defin e an intake path. A check valve (88) in the intake path permits fluid flow fro m the intake port (78) to the pump (24) and for checking fluid flow from the pump (24) to the intake port (78). The second portion (62) of the seal assembly (34) comprises at least part of the check valve (88).
