304 Stainless Steel construction pressure-sensitive regulating unloader designed for industrial use. Features multiple 1/2" ports for convenient mounting. Color-coded spring makes it easy to identify and change from one model to the next as needed.
The CAT Pumps 7533 provides relief for single or multiple pump, weep, or multi-nozzle systems. Senses pressure built up from downstream flow changes and by-passes flow to protect pump from overpressure. Maintains full system pressure while running in by-pass without full load on pump. Provides for minimum pressure fluctuations across multiple guns in use at same time.
