External gear hydraulic pump with acoustical insulation

An external gear hydraulic pump comprising:

• a pump body housing rotating pinions that mutually engage;
• a cover;
• a pump support forming an outlet manifold for high pressure fluid, wherein the cover and the pump support are located on opposite sides of the pump body;
• and
• acoustic insulation for damping vibrations produced by the pinions, the acoustic insulation comprising an acoustic insulation element acoustically decoupling the pump body from the pump support, wherein
• the pump support includes distinct first and second pieces,
• the first piece is integrally connected to the pump body and constitutes a support body, and
• the second piece constitutes the outlet manifold for the high pressure fluid, and
• the acoustic insulation element is interposed between the first and second pieces so the first and second pieces are not in physical contact with each other.
