Fabbay Utility Impeller Replacement Water Transfer Pump Impeller
The Fabbay impeller set includes two units designed to replace worn impellers in water pumps. Each impeller features a D-shaped geometry to match 5/16″ shafts. The exterior rubber is engineered for durability, reducing deformation under routine use. This option suits daily replacements for small transfer pumps, delivering reliable performance over time.
VEVOR Water Transfer Pump 115V
This 115V transfer pump from VEVOR delivers up to 360 GPH with a 46 ft lift, making it suitable for versatile water removal tasks. It comes with a robust aluminum alloy body and a portable handle. The kit includes essential components like an impeller, helping users maintain efficient water transfer in remote or temporary setups. The flat-base design enhances stability and reduces noise during operation.
2 Pack Utility Pump Replacement Impeller for Trupow PAS-30 / PDS-30
These Vanshly impellers are designed for Trupow PAS-30 and PDS-30 pumps. With a 1-3/8″ diameter and 1/2″ width, they feature a D-shaped hub for a 5/16″ shaft. The impeller material (XNBR) provides wear and abrasion resistance, and the D-shaped inner brass ring reinforces structural durability for repeated use in utility pumping applications.
5 Pack Utility Pump Replacement Impeller for Trupow PAS-30 / PDS-30
This Vanshly five-pack offers value for bulk replacements with the same sizing: 1-3/8″ diameter, 1/2″ width, D-shaped hub for 5/16″ shafts. It’s compatible with many utility pumps featuring 1/10th to 1/12th HP AC and DC motors, including Trupow PAS-30 and PDS-30 models. The set emphasizes wear resistance and long service life through durable construction.
Graf Water Pump With Metal Impeller
Graf offers a water pump with a metal impeller suitable for engine cooling or other water movement needs. While not a direct Trupow/PDS-30 replacement, it provides a robust option for compatible systems that require stronger impeller durability and metal build for heavy-use or marine environments.
LucaSng Water Pump Impeller (Tohatsu/Nissan/Mercury)
The LucaSng impeller is designed for Tohatsu, Nissan, and Mercury outboard motors. It is intended for 4-stroke engines in the 2/4 HP class, replacing specific Yamaha/Mercury/Sierra components as needed in compatible setups. This option broadens the scope of replacement possibilities for small marine engines that rely on reliable impeller function for coolant or wash-down systems.
Buying Guide
Key purchase considerations for impellers include compatibility, material, and intended use. Match diameter, width, and shaft fit (commonly 5/16″ shafts and D-shaped hubs) to your pump model (1/10th, 1/12th HP AC/DC motors, or specific PAS-30/PDS-30 configurations). Material choices range from rubber and nitrile compounds to metal-improved designs; rubber variants can offer flexibility and resilience in less demanding environments, while nitrile and metal options can handle higher wear or tougher fluids.
Durability and wear resistance are crucial for long service life, especially in frequent-use or outdoor pumping tasks. Stability features, such as a broader base on the pump body and a durable housing, contribute to quieter operation and reduced vibration. When shopping, consider whether you need a single impeller replacement or a multi-pack set for easy future maintenance.
Additionally, assess compatibility with your pump’s motor type (AC vs DC), horsepower class, and the specific model family (Trupow PAS/PDS, Vanshly variants, Pindex, etc.). For marine applications, ensure the impeller materials resist wear from saltwater exposure and provide durable performance across seasonal cycles.
Finally, consider availability and value. Multi-pack options—like 2-pack or 5-pack sets—help reduce downtime by providing ready replacements, while known-brand reliability and warranty terms can offer reassurance for critical pumping tasks.
