8.The pressure rings (item 30) can now be removed by pulling straight out. Inspect and clean manifold (29) and pressure ring. Replace if necessary. From the front of the pump reinstall pressure rings into manifold (29) with grooved side towards front of manifold. Install new v-sleeves (31 or 50), with grooved sides towards front of pump. For P46W-HK & P46HT pumps, install high temperature seal (31A) with grooved sides towards front of pump. Replace the support rings (32) and pressure springs (33) into mani- fold (29). Install valve assembly (34-40) into manifold (29). Reinstall manifold plugs (43) and torque plugs to 52 ft.-lbs.

9.The rear V-sleeve housing (48) may be removed by prying evenly outward with a flat screwdriver. After slipping housing over plunger, inspect seals (50) and O-ring (49) and replace as necessary.

10.Inspect ceramic plunger (24A) tips for wear. If necessary, replacement of the ceramic plungers may be accomplished by removing the plunger bolt assemblies (24B and 24C) with a 13mm wrench. Ceramic plungers should now slide off the stainless steel plunger base (22). Excessive resistance to plunger removal may be overcome by heating the stainless steel plunger base. This will melt any excess loc- tite beneath the ceramic plunger allowing easy removal.

11.Replace copper ring (24C) onto plunger bolt (24B). Slide plunger bolt assembly into ceramic plunger (24A). Apply a light film of loc-tite to plunger bolt threads and place plunger assembly onto stainless steel plunger base (22) and tighten to 105 in.-lbs.

12.To replace plunger oil seals (26), proceed to “Gear End Disassembly” section below. Otherwise, continue as de- scribed below.

13.Before replacing pump manifold (29), first rotate crankshaft (18) until two outside plungers (24A) extend evenly forward. Next lubricate v-sleeves (50) in the rear v-sleeve housing (48) and slide housing over plungers. Lubricate ceramic plungers with a light film of oil. Carefully and evenly slide manifold over plungers and press manifold firmly against crankcase

(1). Replace manifold stud bolts (45), washers (47) and nut (46) and tighten to 35 ft.-lbs.

Triplex Ceramic Plunger Pump specifications

The Giant Triplex Ceramic Plunger Pump is a cutting-edge solution designed to meet the demanding needs of high-pressure applications in various industries. Known for its durability and efficiency, this pump provides reliable service in tasks such as pressure washing, industrial cleaning, and other high-flow, high-pressure operations.

One of the standout features of the Giant Triplex Ceramic Plunger Pump is its triplex design. Unlike traditional single-piston pumps, the triplex configuration uses three plungers that work in a staggered sequence. This results in smoother operation, reduced pulsation, and improved overall performance. The synchronized action of the plungers ensures that fluid delivery is constant and consistent, which is crucial for applications requiring high pressure.

The pump is equipped with ceramic plungers, which are engineered to withstand abrasive materials and harsh chemicals. These ceramic components offer exceptional resistance to wear and tear, extending the lifespan of the pump and reducing maintenance costs. This durability is especially beneficial in industrial settings where the pump may encounter contaminants or abrasive substances.

Another technological advancement found in the Giant Triplex Ceramic Plunger Pump is its built-in unloader valve. This crucial component protects the pump from excessive pressure buildup, allowing for safe and efficient operation. In situations where the pressure exceeds pre-set limits, the unloader valve automatically diverts or bypasses the flow, preventing potential damage to the pump and other connected equipment.

Additionally, the Giant Triplex pump features a brass head construction that enhances its strength and robustness. This design also allows for better heat dissipation, ensuring that the pump operates efficiently even under high-pressure conditions. The incorporation of high-quality seals and O-rings enhances the pump's reliability by preventing leaks and ensuring optimal performance over time.

Overall, the Giant Triplex Ceramic Plunger Pump is renowned for its high efficiency, longevity, and robustness. These characteristics make it an ideal choice for various high-pressure applications across industries. Its advanced technologies, including the triplex design, ceramic plungers, built-in unloader valve, and robust construction, provide users with a reliable and effective pumping solution that meets the challenges of modern industrial demands. Whether for pressure washing, cleaning, or other demanding applications, this pump stands out as an essential tool for professionals seeking performance and durability.
