Pentair | 355122 | Dynamo 1 HP Impeller | Replacement Pump Impeller
Pentair 355122 is a replacement 1 HP impeller designed for compatible Dynamo pump applications. This internal wet end component mounts within the pump assembly and helps move water through the circulation system during normal operation, making it suitable for service and repair when the original impeller becomes worn, damaged, or no longer performs correctly.
Key Features
• This impeller is designed for compatible Pentair Dynamo pump applications that require the exact 1 HP replacement configuration.
• The impeller functions as the internal water-moving component within the pump wet end assembly.
• Proper impeller fit is important for maintaining intended water circulation through the pump and connected plumbing system.
• This replacement part is suitable for service work when the original impeller becomes worn, cracked, damaged, or no longer performs correctly.
• The 1 HP rating is a critical specification for matching the correct pump configuration identified by this part number.
• This component is intended for pump rebuild or repair applications where the exact replacement part number is required.
• Using the correct replacement impeller helps preserve the original fit and operating function of the existing pump assembly.
• Pentair SKU 355122 should be matched by exact part number for proper compatibility and replacement selection.
Product Overview
The Pentair 355122 Dynamo 1 HP impeller is a replacement internal pump component used in compatible Dynamo pump assemblies. As part of the wet end, the impeller plays a central role in moving water through the pump housing and into the circulation system during normal operation. Because impellers are application-specific, correct part-number matching is important during maintenance and repair.
This replacement part is typically used when the original impeller has become worn, damaged, or less effective due to normal service conditions. Installing the correct replacement impeller helps maintain proper fit within the pump assembly, supports dependable circulation performance, and preserves the serviceability of the existing Dynamo pump without requiring replacement of the complete unit.
