REPAIR INSTRUCTION - P200A-3100/5100 SERIES

Disassembly sequence of fluid end of P200A-3100/5100 series pump

Note: Always take time to lubricate all metal and nonmetal parts with a light film of oil before reassembly. This step will ensure proper fit, at the same time protecting the pump nonmetal parts (i.e., the elas- tomers) from cutting and scoring.

1)With a 22mm socket wrench, remove the (3) discharge valve plugs and (3) inlet valve plugs (32). Inspect the o-ring (33) for wear and replace if damaged.

2)Using a needle nose pliers, remove the inlet and discharge valve assemblies (32X). By inserting a small screw driver between the valve seat (27) and the valve spring retainer (30), the valve assembly can be separated. Remove the o-ring (31). Inspect all parts for wear and replace as necessary.

3)Next, use a 5mm allen wrench to remove the 8 socket head cap screws (34). Carefully slide the valve casing (26) out over the plungers. Remove the weep return ring (25), pressure ring (24), and v-sleeve (23) from the valve casing (26). Remove the v-sleeve (23) from the seal case (20). Inspect all parts, including o-ring (21) for wear and replace as necessary.

4)Check surfaces of plunger (16). A damaged surface will cause accelerated wear on the seals. Depos- its of any kind must be carefully removed from the plunger surface. A damaged plunger must be replaced!

5)If the ceramic plunger pipe (16B) is damaged, remove the plunger bolt (16C). Discard the old plunger pipe (16B) and copper gasket (16D), and clean the old locktite from the plunger bolt (16C) and plunger base (16A). Replace the plunger with the new one and locktite the plunger bolt and torque to 220 inch- pounds.

Note: If there are deposits of any kind (i.e., lime deposits) in the valve casing, be certain that the weep holes in the weep return ring (25) and valve casing (26) have not been plugged.

5)If the crankcase oil seals (19) are to be replaced, they can be removed by prying loose with a flat screwdriver. Take care not to make contact with the plunger. If the oil seals are not to be replaced, proceed to the back end disassembly sequence and carefully pry the seals loose after the plungers have been removed from the crankcase. The seals should not be reinstalled until after step #2 of the "Reas- sembly Sequence".

Triplex Ceramic Plunger Pump, P200A-3100/5100 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.
