The CPI purge gun provides a convenient, cost effective method to remove all air from the divider block system to ensure all lubrication points will receive lubrication immediately on start-up of the compressor. The manual pump is also an efficient way to troubleshoot the divider block system to locate blockage in divider blocks, tubing lines and cylinder/ packing injection points. The pump delivers full pressure at a minimum stroke for ease of use in tight quarters. All pumps are provided with 36” (914 mm) stainless steel braided hose for long reach applications, 5,000 psi stainless steel liquid filled pressure gauge and chrome-plated steel tube with bullseye sight glass.
