Performance Data
JETECH® pumps are available up to 1,400 horsepower covering a hydraulic pressure range up to 40,000 PSI and up to 650 GPM. All JETECH® Liquid Ends are available with the same positive design features as the 225J3.
The JETECH® 225J3 triplex plunger pump represents a new dimension of rugged versatility in high and ultra-high pressure pumping equipment. Designed to meet the demanding requirements of chemical injection, oil field, API processing, reverse osmosis, mining and water blasting applications, the pump is engineered to provide long dependable service and ease of field maintenance.
LIQUID END FEATURES:
All JETECH® “AD” (Advanced Designed) 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 sufrace 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 225J3 pump 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.POWER END FEATURES:
The JETECH® Model 225J3 pump utilizes a rugged cast iron power frame that has been engineered to provide years of dependable service. At the heart of this Power End is a precision-machined crankshaft that is made from high strength alloy steel to give plenty of reserve horsepower. Power is transmitted from the heavy duty crankshaft to the rugged cast steel connecting rods and the solid cast iron crossheads.The Power End has “splash lubrication” with the connecting rods dipping into the oil reservoir, sending oil into the connecting rod bearing and splashing oil into the tapered roller bearing at both ends of the crankshaft.
The unique feature of this unit is the small, stainless steel reservoir tank that is mounted above the crosshead guides. Used as a heat exchanger, this cooling system cools the crankcase oil and provides liquid to cool and lubricate the plungers.
BEARINGS:
The main end bearing are the tapered roller design to withstand high loads. The crankshaft journal bearings are automotive-type with steel backed inserts.MAINTENANCE FEATURES:
The Liquid Ends of the 225J3 pump offer 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 which requires only the disconnecting 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 speial 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 easily be 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 225J3 pump.
