$690.52

Model: 7536

This Stainless Steel Pressure Sensitive Regulating Unloader is designed for single or multiple pump, weep or multi-nozzle systems. This unloader maintains set system pressure and goes into by-pass with the release of the trigger or an obstruction downstream. Pressure is held in the line during by-pass with full pressure when the gun is opened or the obstruction cleared and minimal pressure fluctuation with the alternating use of multiple guns. 5-10% by-pass is necessary for optimum performance.

FEATURES

• Maintains full system pressure while running in bypass without full load on pump.
• Senses pressure built up from downstream flow changes and bypasses flow to protect pump from overpressure.
• Minimum pressure fluctuations with alternating use of multiple guns.
• Multiple ports provide for convenient mounting.
• Color coded spring allows for easy identification and simple change from one model to another.
• Standard unloaders are fitted with NBR O-rings. Optional O-rings are available for higher temperature and chemical compatibility.
• FPM – .0110 (7531.0110)
• FPM – .0110 (7533.0110)
