High pressure pump, frame and housing assembly

Abstract

The invention is a high pressure pump, frame and housing assembly including a high pressure pump, electric motor, belt drive, metal frame, plastic housing and noise absorbing sheets that combine to suppress vibration, attenuate noise and allow viewing of the motorized pump assembly. The motorized pump produces a flow rate of at least 4 gpm at a pressure of at least 2,000 psi, while the assembly keeps the noise level at or below about 77 decibels. Vibrations are suppressed by the frame and housing which are formed by irregularly shaped and sized frame members, segments and panels. The housing panels combine with the porous noise attenuating sheets to form dead zones for absorbing noise. The sheets and dead zones are compactly arranged inside the frame segments. Two transparent panels form dual opposed windows for lighting and viewing the active internal components.
