<p>The pump has a pump body (1) for housing rotative pinions, and a pump cover (3) and a pump support (4) fixed on front surfaces of the body. An acoustic insulation unit dampens vibrations produced by the pinions and includes acoustic decoupling elements formed by ring washer (33), decoupling sheet (42) and acoustic insulation washer, for uncoupling the body from the support. The sheet is made of elastomer e.g. nitrile. The support is formed by a front support body (16) and a manifold (17) comprising a high pressure fluid outlet, where the body (16) is integrated to the body (1).</p> |
