<h2>Overview</h2>
<p>The <strong>Wilkes & McLean WM-3138-16</strong> is a hydraulic shock and noise suppressor engineered to attenuate pressure pulsation, vibration, and acoustic noise in hydraulic systems. Sized for 1-inch line applications, this suppressor is installed downstream of pump outlets to protect downstream components and reduce system-wide noise generation. The unit’s compact design minimizes footprint while maintaining effective noise attenuation across a wide range of operating conditions.</p>
<h2>Key Features</h2>
<ul>
<li>Reduces hydraulic noise, vibration, and pulsation in pump discharge lines</li>
<li>Compact, lightweight design with minimal pressure drop penalty</li>
<li>Rated for industrial hydraulic pressures up to 3000 PSI</li>
<li>Designed for 1-inch (1″) SAE port line size</li>
<li>Simple installation at pump outlet with standard SAE port mounting</li>
<li>Low maintenance—no complex sizing formulas required</li>
</ul>
<h2>Technical Specifications</h2>
<p>The suppressor accommodates standard industrial hydraulic system pressures and delivers reliable performance across diverse pump and motor applications. Mounting provisions support both in-line SAE ports and optional flange configurations. Typical pressure drop across the unit approximates the equivalent of one foot of standard tubing, allowing for minimal system efficiency impact.</p>
<h2>Typical Applications</h2>
<ul>
<li>Fixed-displacement pump outlets requiring noise suppression</li>
<li>Industrial machinery with acoustic performance constraints</li>
<li>Mobile hydraulic systems (construction, agricultural equipment)</li>
<li>System retrofits where pulsation damping is required post-installation</li>
<li>Multi-pump systems experiencing cumulative noise generation</li>
</ul>
<h2>Compatibility & Replacements</h2>
<h3>Compatible With</h3>
<ul>
<li>Fixed and variable displacement hydraulic pumps</li>
<li>Standard SAE port hydraulic manifold systems</li>
