HC-PTO-3AC PTO Pump, Cast Iron, 5.7 CI/Rev, 21 Tooth Drive, 540-1000 RPM, 2250 PSI Max

The HC-PTO-3AC PTO Pump from Prince Manufacturing represents a superior choice for those seeking durability and efficiency in high-performance applications. With its robust cast iron construction, this pump is designed to withstand the rigors of demanding tasks while maintaining optimal functionality.

Featuring self-adjusting wear plates that effectively seal around the two unequal size gears, the HC-PTO-3AC ensures a reliable operation. These wear plates are activated by internal fluid pressure, which helps offset wear or expansion, leading to enhanced longevity and performance. This innovative design minimizes maintenance needs, allowing for uninterrupted operation on the job.

Included with the pump are various porting adapters to ensure compatibility with your existing systems. Specifically, it comes equipped with an inlet port adapter (SAE O-ring boss to hose barb) and an outlet port adapter (SAE O-ring boss to female pipe threads). This versatility makes it easier to integrate into a wide range of applications, simplifying installation and setup.

Importantly, the HC-PTO-3AC is engineered to operate under specific conditions. The oil operating temperature should not exceed 180 degrees Fahrenheit; if it does, it may indicate that the reservoir is too small or that a heat exchanger could be necessary. This attention to operational parameters ensures that you can rely on this pump for consistent performance.

Designed to function at up to 100% of standard PTO shaft speeds, the HC-PTO-3AC can seamlessly operate at both 540 RPM and 1000 RPM. This adaptability makes it an ideal choice for a variety of applications, whether you are utilizing it on agricultural machinery or other heavy-duty equipment.

With a maximum relief valve setting of 2250 PSI, the pump is capable of handling substantial pressure. However, it is crucial to provide an external relief valve in your system to ensure safe and effective operation. This feature highlights the importance of proper system design when integrating the HC-PTO-3AC into your machinery.

A standout feature of the Prince PTO pumps is the minimum clearance between the gears and the center housing. Each pump is assembled with zero clearance between the housing and the tips of the gear teeth. It undergoes a testing process that allows the teeth to establish a proper wear path in the housing. This meticulous assembly results in a much tighter clearance compared to traditional or imported pumps, leading to enhanced efficiency and reliability.

In summary, the HC-PTO-3AC PTO Pump is a testament to Prince Manufacturing’s commitment to quality and performance. Whether you are looking for durability, efficiency, or innovative design, this pump checks all the boxes, making it a wise investment for any serious operator.
