Design Features of Reciprocating Plunger Pumps
The RDP series of Reciprocating Plunger Pumps are suitable for handling a variety of liquids for nuclear applications. The RDP pump series are a type of positive displacement pump where a smooth cylindrical plunger slides through the seal, making it different from piston pumps and allowing higher pressures.
- A variety of sizes in Triplex and Quintuplex formats
- Designed in accordance with ASME and RCC-M
- Stuffing box can be removed without pump disassembly
- Excellent noise and vibration characteristics < 85dB(A)
- Spring loaded, auto adjustment braided compression and chevron packing, minimizes leakage
