REPAIR INSTRUCTIONS - P46W, P46W-HK, P46HT

1.With a 22mm socket, remove the three discharge (43) and three inlet (41) manifold plugs. Check o-rings (42 & 44) for wear and replace as necessary.

4.Drain the oil from the pump. Turn the pump over to remove the two manifold stud nuts (46) with a 17mm wrench.

2.Remove the discharge spring retainer (34), valve spring (35), and valve plate (36).

5.Tap the back of the manifold (29) with a rubber mallet to dislodge, and slide off the pump.

3.Use a small slide hammer to remove valve seats (37) from manifold (29). Inspect valve plates (36) and valve seats (37) for wear. If excessive pitting is seen, replace the worn parts. Check valve seat o-ring (38) for wear and replace as necessary.

6.From the front inlet valve ports, remove the inlet valve assembly (34-40).

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.
