A reciprocating-type pump with simplified construction and enhanced performance is achieved by the use of a unitary, rigid pump body support structure and modular pump component designs. This unitary structure includes forward and rearward pump body mounting plates to which the pump body is secured, with the overall support structure being securely attached to the power frame of the pump by means of a power frame mounting plate. Rigid connecting members secure said plates together to form the unitary structure that is particularly advantageous for use in the fabrication of cryogenic pumps suitable for high pressure operation. Valve means, packing means and a pump body cooling jacket can be conveniently secured to the unitary support structure.
