Overview

This document provides detailed performance data and specifications for the Micropump DV-955.A air motor, a pneumatic drive unit. It includes graphical data on output power, torque, and air consumption relative to motor speed and operating pressure.

Performance Specifications

Output Power vs. Speed

The output power is presented in both horsepower and kilowatt units, plotted against output speed in RPM. The data is shown for various intake air pressures ranging from 20 psi (1.4 bar) up to 100 psi (7.0 bar). Output power increases with speed and pressure, reaching a maximum near 0.5 horsepower at 100 psi and 10,000 RPM.

Torque vs. Speed

Torque is provided in pound-inches (LB.IN.) and Newton-meters (Nm), also plotted against speed for the same range of pressures. Torque decreases as speed increases, with higher torque values at higher intake pressures. Maximum torque is approximately 7 LB.IN. (0.8 Nm) at low speeds and 100 psi.

Air Consumption vs. Speed

Air consumption is detailed in cubic feet per minute (CFM), liters per second (l/s), and cubic meters per hour (m³/h), plotted against speed and intake pressure. Air consumption rises with speed and pressure, reaching up to 10 CFM at 100 psi and 10,000 RPM.

Technical Parameters

• Maximum Intake Air Pressure: 100 P.S.I.G.
• Pneumatic Connection: 1/8–27 N.P.T. thread
• Model: DV-955.A
• Drive Type: Pneumatic air motor

Key Insights and Recommendations

• Performance varies significantly with intake air pressure; higher pressures yield greater power and torque but also increase air consumption.
• Torque decreases as speed increases, indicating a trade-off between speed and torque output.
• Air consumption data is critical for system design to ensure adequate air supply and efficiency.
• Users should consider operating within specified pressure limits to avoid performance degradation or damage.

Summary

The Micropump DV-955.A air motor offers variable output power and torque depending on speed and intake pressure, with detailed performance curves provided for design and operational optimization. The unit requires a maximum intake pressure of 100 psi and standard pneumatic connections. Understanding the relationships between speed, torque, power, and air consumption is essential for effective application and system integration.
