XPR860P/XPR1560P POWDER PUMP SECTION 1 WARNING: Always wear safety glasses when operating a pump to avoid eye injury. If diaphragm rupture occurs, CAUTION: Maximum temperature limits are based on material being pumped may be forced out of the air mechanical stress only. Certain chemicals will reduce exhaust.

XPR860P/XPR1560P POWDER PUMP SECTION 3 HOW IT WORKS – AIR-OPERATED DOUBLE-DIAPHRAGM PUMP The Wilden diaphragm pump is an air-operated, positive displacement, self-priming pump. These drawings show flow pattern through the pump upon its initial stroke. It is assumed the pump has no fluid in it prior to its initial stroke. FIGURE 1 The air valve directs pressurized air to FIGURE 2 When the pressurized diaphragm, FIGURE 3 At completion of the stroke, the air...

XPR860P/XPR1560P POWDER PUMP SECTION 3 HOW IT WORKS – POWDER FLUIDIZATION SYSTEM In the main pump design, each of the four valve balls is equipped with two purging points, and an additional purging point has been added at the inlet. This configuration aims to enhance the cleaning efficiency of the pump, ensuring no residual materials affect the pump's performance. For this purpose, compressed air is used as the purging medium.
XPR860P/XPR1560P POWDER PUMP SECTION 6 SUGGESTED INSTALLATION, OPERATION, MAINTENANCE AND TROUBLESHOOTING Wilden pumps are designed to meet the performance requirements of be eliminated. In addition, pump efficiency can be adversely even the most demanding pumping applications. They have been affected if proper attention is not given to site location. designed and manufactured to the highest standards and are •...

XPR860P/XPR1560P POWDER PUMP SUGGESTED INSTALLATION, OPERATION, MAINTENANCE AND TROUBLESHOOTING Troubleshooting Also, as the check valve balls wear out, they become smaller and can become stuck in the seats. In this case, replace balls and seats. Pump will not run or runs slowly. Checking if the valve balls are sticking: Remove plug from pilot spool exhaust.
XPR860P/XPR1560P POWDER PUMP SECTION 7 DISASSEMBLY / ASSEMBLY FLUIDIZATION SYSTEM DISASSEMBLY Tools Required: CAUTION: Before attempting any maintenance or repair, disconnect the compressed • air line to the pump and allow all air pressure to bleed from the pump. Disconnect all Socket Wrench intake, discharge, and air lines.
