Claim:
1. A pump system comprising: a pump housing defining a pump bore; a pumping member disposed in the pump bore and reciprocal along a bore axis to pump a fluid; a fluid intake manifold formed as part of the pump housing and arranged to contain a quantity of fluid at a low pressure; a fluid discharge manifold formed as part of the pump housing and arranged to contain a quantity of fluid at a high pressure; and a valve assembly arranged in a fully operable condition and insertable and removable into the pump housing in the fully operable condition, the valve assembly associated with the pump bore and including: a valve body; a suction valve coupled to the valve body and movable along the bore axis between a closed position and an open position; a first cage fixedly connected to the valve body; a first spring cooperating with the first cage to bias the suction valve toward the closed position, the first spring positioned between the first cage and the suction valve such that the first cage fixedly attaches the first spring to the valve body; a discharge valve coupled to the valve body and movable along the bore axis between a closed position and an open position; a second cage fixedly connected to the valve body; and a second spring cooperating with the second cage to bias the discharge valve toward the closed position, the second spring positioned between the second cage and the discharge valve such that the second cage fixedly attaches the second spring to the valve body; and a plurality of discharge channels formed as part of the valve body and arranged to direct high pressure fluid from the pump bore to the discharge valve.
