Constant Pressure (CP) Pump Pump maintains constant fluid pressure for superior performance in automotive applications. Features and Benefits Overlapping pump stroke provides uniform and constant pressure, eliminating fluctuations and pressure winks. Independent output pressure is not affected by inlet pressure. Uniform pressure provides smooth, uninterrupted material application. Simple design facilitates quick replacement of air valve and hydraulic packing glands for easy, on-line maintenance. Self-starting inter-connection automatically initializes both pumps whenever air pressure is activated. The Nordson Constant Pressure (CP) Pump is an air-driven pump used in the application of automotive adhesive and sealant materials including high viscosity, cold-applied plastisols, epoxies and body sealers. Designed for use in demanding automotive production environments, the CP pump provides superior flow and pressure control. High-Performance Operation The Nordson CP pump solves the problem of pressure fluctuation seen in conventional double-acting pumps by uniting two single-acting, air-powered hydraulic pumps in a side-by-side configuration. One pump discharges while the other pump fills. Less time is required for filling than for discharging. As a result, one pump is filled and remains in a ready state before the first pump has finished discharging. Shifting from one pump to the other is controlled to provide adequate overlap in the pump strokes, eliminating pressure fluctuations. In actual operation, pump A is activated, forcing the plunger downward and discharging material through the outlet check valve. When pump A approaches empty (or the end of its discharge cycle), pump B is automatically activated and begins supplying material. Pump A then refills and waits until pump B is nearly empty to automatically activate and begin the next cycle. Ease of Maintenance The CP pump is constructed for fast, easy and safe maintenance. Components are simple in design and easily accessible for ease of on-line routine servicing and reduced maintenance costs. Nordson FastPack™ replacement packings are supplied in factoryassembled cartridges to provide a proper pump shaft seal and to minimize downtime. The self-adjusting packing gland does not require maintenance and eliminates failures caused by over tightening. Packing cartridge being removed with screwdriver. Self-adjusting FastPack™ replacement packings are easy to replace and do not require maintenance.
