“AD” LIQUID-END CONVERSION PACKAGE


“AD” LIQUID-END CONVERSION PACKAGE
	Pressures to 40,000 PSI
The JETECH® “AD” Liquid-End Conversion Package may be the solution to your operational and maintenance problems! Don’t tolerate lengthy down-time, limited operating pressure range, and expensive replacement parts and maintenance cost with your existing water-blast pump. Modernize it by replacing the original style liquid-end with the JETECH® “AD” Liquid-End Conversion Package. The JETECH® “AD” Liquid-End Conversion Package is designed to fit most existing water-blast pump gear ends regardless of the gear end manufacturer. The JETECH® “AD” Liquid-End Conversion Package will permit you to operate up to 40,000 PSI pressure, and at the same time you will profit from its exceptional ULTRA-EASY MAINTENANCE FEATURES. An examination of the “AD” Liquid-End will convince you that no other pump offers so many positive design and maintenance features. LIQUID-END FEATURES: All JETECH® Advanced Design Liquid Ends are precision-machined to exacting tolerances and feature segmented cylinders of the radial compression, single-bore design. The radial compression, single-bore feature eliminates undesirable bore intersections and cylinder tensile stresses which are known to be the major factors leading to pump cylinder failure. SINGLE-SPRING VALVES: The JETECH® unique single-spring radial compression inline valve cartridge design eliminates the traditional discharge valve spring required in other plunger pumps. Since only one spring serves both suction and discharge valves, the single-spring feature effectively reduces the possibility of valve spring breakage up to 50% over two spring units. PLUNGERS: The plungers are manufactured to exacting tolerances of nominal OD (+0.000/-0.001) inches. A choice of ceramic or JETECH® 060 NICKEL-CHROME-BORON fused hard coatings is available. Minimum coating thickness is 25 mils and minimum surface hardness is 60 Rc. Plungers are ground to a smooth surface finish of 8 RMS to provide long packing life. PACKING: The pump is designed to accommodate a broad spectrum of packing arrangements. The standard arrangement is the non-adjustable, spring loaded style that can be fitted with vee, square, or JETECH® flat-backed chevron rings to withstand high pulsing loads. STUFFING BOXES: The stuffing boxes of the “AD” Liquid-End are engineered as part of the segmented cylinders and are designed without radii. This important feature is essential to eliminate radii stress points which are the prime sources of stuffing box cracking. MAINTENANCE FEATURES: The “AD” Liquid-End offers many ease of maintenance features. The segmented liquid cylinders are held to a common manifold by four through-manifold bolts that screw into a back cylinder holding plate. The removal of each cylinder is a simple task that requires only the unscrewing of the plunger from the pony rod and the removal of the four through-manifold bolts, which are accessible from the front of the manifold. Packing, plunger, valve, and cylinder changes can be accomplished in short time spans and do not require special skills of the workman. In fact, the valve cartridge can be removed from the pump without loosening the plunger or disturbing the packing. All that is required is the loosening of the four through-manifold bolts and the sliding back of the cylinder approximately two inches toward the Power End. The valve cartridge can then be easily lifted from between the manifold and cylinder. This feature is great for quick suction and discharge valve inspection, or component changing. When it comes to ease of field maintenance, no other through-bore type pump comes close to the exceptional versatility of the JETECH® “AD” Liquid-End. MAINTENANCE FEATURE SUMMATION: Easy maintenance with minimum down-time. Fewer moving parts than conventional plunger pumps. No special tools required. Common suction/discharge manifold does not have to be removed - no heavy parts to lift. All bolts are accessible from the front of the pump. “Lift out” valve cartridge - allows easy inspection and maintenance. Cartridge can be removed without disconnecting the plunger. Does not require disconnecting hoses or plumbing to the manifold.
