Giant Triplex Ceramic Plunger Pump, P200A-3100/5100 instruction

REPAIR INSTRUCTION - P200A-3100/5100 SERIES

Disassembly sequence of the back end of the P200A-3100/5100 series pump.

1)Before you begin, drain the oil from the crankcase.

2)Remove the crankcase cover (3) and o-ring (4) from the crankcase (1). To remove the crankshaft (13), remove the bearing cover (7) and sight glass (8). Using a rubber mallet, remove the crankshaft axially through the connecting rods by tapping on the end of the shaft. Be careful not to bend or damage the connecting rods during crankshaft removal.

3)If the bearings (12A and 12B) and radial shaft seal (11) are still in the crankcase, remove them. Inspect both bearings and seal for wear and replace if necessary.

4)Remove the connecting rod (15) and plunger (16). Remove the wrist pin (17) if necessary. Check the plunger bore in the crankcase for wear. Inspect parts and replace as necessary.

5)Should you find it necessary to service the plunger assembly (#16) you can do so by removing the tension screw (#16D). Inspect all parts and replace as necessary.

Reassembly sequence of the of the P200A-3100/5100 series pump

1)Reassemble plunger (16) and the connecting rod (15) with wrist pin (17). Place assemblies in crankcase

(1). Install crankshaft through connecting rods again being careful not to bend or otherwise damage the connecting rods.

2)Replace left and right side bearings (12A and 12B) if they were removed from the crankshaft. Be certain the bearings are pressed all the way onto the shaft and completely into the crankcase. Replace radial shaft seal (11), bearing cover (7), sight glass (8), and crankcase cover (3) with its o-ring (4).

3)If oil seals (19) were removed, replace with seal lip towards crankcase. Lubricate seal before replacing.

4)Replace seal case (20) with o-rings (21) over plungers. Generously lubricate o-rings and oil seal before reassembly. Replace v-sleeve (23) over plungers (16)..

5)Generously lubricate v-sleeve (23). Assemble v-sleeves (22) into valve casing (#26). Assemble weep return ring (25) and pressure ring (24) over plungers (16). Slide valve casing over plungers and seat firmly. Replace the eight socket head cap screws (34) and tighten to 105 inch-pounds in a crossing pattern.

6)Replace the six o-rings (31) and the six valve assemblies (32X). Now replace the six valve plugs with o- rings (32 and 33) and tighten securely with a 22mm socket wrench to 33 foot-pounds.

7)Fill crankcase with 9.5 ounces (6.5 ounces for P217A) of oil.

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.
