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
- Valves in a cartridge design, easy removal and replacement
- Configurable for drives, lubrication and skids
- Design life of 20 years
Package Options:
- Dampeners, PSV’s and instrumentation can mount directly to pump head
- Motor can mount directly to top of crankcase for compact offshore footprint
- ATEX compliance
- Package condition monitoring
- Various seal and power end lubrication options
- Electric motor
- Diesel or petroleum engine
- Hydraulic motor
- Variable speed drive
- Various transmission options including: Gearbox / V-belt drives

Reciprocating Plunger Pumps FAQs
What is a Reciprocating Plunger Pump?
A Reciprocating Plunger Pump is a type of positive displacement pump that uses a smooth cylindrical plunger that slides through a seal. This design differs from piston pumps and allows for operation at higher pressures. The RDP series is specifically designed for handling various liquids in nuclear applications.
What are the typical applications for RDP pumps in nuclear facilities?
Common applications include:
– Water/Boron Injection Pumps
– Chemical injection systems
Who manufactures the RDP series pumps?
The RDP series pumps are supplied through a partnership between Hayward Tyler and Ruhrpumpen, allowing them to comply with existing nuclear codes including ASME and RCC-M.
What configurations are available in the RDP series?
The RDP series is available in a variety of sizes in both Triplex (three-plunger) and Quintuplex (five-plunger) formats, allowing customers to select the configuration that best meets their specific flow and pressure requirements.
What are the maximum operating parameters of RDP pumps?
– Maximum Capacity: 1611 USgpm (366.5 m³/hr)
– Maximum Discharge Pressure: 14,500 psi (1,000 bar)
– Operating Temperature Range: -104°F to 392°F (-40°C to 200°C)
– Maximum Pump Speed: 450 rpm (Note: This maximum speed is allowed by API674 but may not always be applicable for nuclear applications)
– Pipe Size Range: 1″ to 8″ (20 to 200mm)
Can the maximum flow and maximum pressure be achieved simultaneously?
No, maximum flow and maximum pressure cannot be met at the same time. These are the upper limits of the pump’s capabilities, but operational constraints prevent achieving both simultaneously.
The RDP pumps are designed for a 20-year operational life, making them suitable for long-term installations in critical applications.
What makes the maintenance of RDP pumps convenient?
Several design features make maintenance more convenient:
– The stuffing box can be removed without pump disassembly
– Valves are in a cartridge design, allowing for easy removal and replacement
– Spring-loaded, auto-adjustment braided compression and chevron packing minimizes leakage
What drive options are available for RDP pumps?
RDP pumps can be configured with various drive options including:
– Electric motor
– Diesel or petroleum engine
– Hydraulic motor
– Variable speed drive
What transmission options are available?
Various transmission options are available including:
– Gearbox
– V-belt drives
Yes, RDP pumps can be supplied with ATEX compliance for use in potentially explosive atmospheres.
