HC-PTO-3A Aluminum PTO Pump, 21 Tooth Drive, 5.7 CI/Rev, 2250 PSI Max Pressure

Introducing the HC-PTO-3A PTO Pump, a product of exceptional engineering from Prince Manufacturing. This aluminum-bodied pump is designed to meet the demands of various applications while providing reliable performance and durability. The HC-PTO-3A features a 21 Tooth Drive and boasts an actual displacement of 5.7 CI/Rev, making it an ideal choice for those seeking efficiency and power in their PTO systems.

One of the standout features of the Prince PTO pumps is their self-adjusting wear plates. These plates seal around two unequal-sized gears, activated by internal fluid pressure. This innovative design helps to offset wear or expansion, ensuring that the pump maintains optimal performance over time. Additionally, every pump comes equipped with an inlet port adapter, transitioning from SAE O-ring boss to hose barb, and an outlet port adapter, transitioning from SAE O-ring boss to female pipe threads. This versatility allows for easy integration into existing systems.

When it comes to operating temperature, it’s crucial to note that the oil temperature should not exceed 180 degrees Fahrenheit. If you find that the temperature exceeds this threshold, it may indicate that the reservoir is too small or that a heat exchanger is required to maintain safe operating conditions. Prince PTO pumps are engineered to operate at up to 100% of standard PTO shaft speeds, with standard operating speeds set at 540 RPM and 1000 RPM, ensuring consistent performance across various applications.

The HC-PTO-3A is designed with a maximum pressure relief valve setting of 2250 PSI. It is important to ensure that an external relief valve is provided in your system to protect against overpressure scenarios, which can lead to pump failure or damage to your equipment. The pumps are built with a center section made of aluminum, contributing to their overall strength and lightweight design.

A notable characteristic that enhances the efficiency and longevity of the Prince PTO pumps is the minimum clearance maintained between the gears and the center housing. Each pump is assembled with zero clearance between the housing and the tips of the gear teeth, followed by a test run until the teeth establish a proper wear path in the housing. This meticulous process results in a much tighter clearance than what is typically found in traditional or imported pumps, leading to improved performance and durability.

In conclusion, the HC-PTO-3A PTO Pump from Prince Manufacturing is a top-tier choice for those looking for reliability, efficiency, and longevity in their PTO systems. With its innovative design and robust construction, this pump is engineered to perform under pressure while ensuring minimal wear and tear over time. Upgrade your equipment with the HC-PTO-3A and experience the difference in performance and durability.
