Fixed Displacement Vane Pump Up to 320 Bar (4640 psi)

Product catalog summary

Overview: The HT6/HT7 Series are high-pressure, fixed displacement, single vane pumps designed for both industrial and mobile applications. These pumps feature a balanced pin-vane design that reduces noise and enhances volumetric efficiency, capable of operating at pressures up to 320 bar (4640 psi).

Specifications: The series includes models such as HT6C, HT6D, HT6E, HT7B, each with displacement capacities from 5.8 cm³/rev to 269.8 cm³/rev. Maximum intermittent pressure ranges from 206 bar (3000 psi) to 320 bar (4640 psi), and maximum continuous pressure ranges from 160 bar (2300 psi) to 290 bar (4200 psi). The operational speed range is 600 rpm to 3600 rpm.

Features: These pumps have a cartridge design independent of the shaft, facilitating easy servicing and flow capacity adjustments without dismounting. They are optimized for low flow at high pressure and high flow at low pressure, especially in the HT7 Series.

Performance Characteristics: Performance varies by model, with specific flow rates and input power requirements at different pressures and speeds. For instance, the HT6C model at 1800 rpm delivers a flow of 47.56 GPM at 0 PSI and requires 86.06 HP at 3500 PSI.

Ordering and Customization: Customization options include different shaft types, rotations, and port connections. The ordering code details model type, ring size, shaft type, rotation, inlet port position, design letter, and port connection.

Installation and Dimensions: Detailed installation dimensions are provided for each model to ensure proper fit and function in various applications.

Additional Specifications: The document specifies dimensions for HT7B and HT7BS models, including shaft diameters and depths for various thread types, and other critical dimensions like ØA, ØB, C, D, ØE, F, G, and ØH.

Performance Characteristics: Detailed performance characteristics include volumetric displacement and operating speeds, with flow rates (GPM) and input power (HP) at different pressures and speeds. For example, a pump with a displacement of 0.35 in³/rev at 1500 R.P.M has a flow rate of 2.29 GPM at 0 PSI and requires 0.67 HP at 100 PSI.

Limitations and Recommendations: Certain models have a maximum internal pressure of 4350 PSI, while others have a maximum of 4000 PSI. It is recommended to avoid configurations where internal leakage exceeds 50% of the theoretical flow. Metric thread port connections are available.

Ohof HYDRAULIC SOLUTION High Pressure Single Vane Pump HT6/HT7 Series Features and Handling • HT6, HT7 Series are fixed displacement and balanced type single vane pumps. The pump is designed for higher operating pressure and greater flow at the same housing size. • With a balanced pin-vane design, outlet pressure is continuously applied only the pin. The pin provides the steady light force against the vane. Top and bottom areas of the vane are subject to the same pressure, either inlet or outlet pressure, depending on the vane's location during rotor rotation. This pin-vane design minimizes noise...
