Core Advantages of Integration

1. Ultra-Compact Design

• Integrated construction: Variable displacement piston pump directly mounted inside the motor housing, eliminating the need for separate mounting brackets and couplings
• Space savings: Overall length reduced by 40-50% compared to conventional pump-motor combinations
• Flexible installation: Can be mounted horizontally or vertically to accommodate diverse machine layouts

2. Exceptional Noise Reduction

• 10-15 dB(A) quieter than traditional separate pump-motor setups
• Internal noise isolation: Pump operates within the motor housing, minimizing sound transmission
• Optimized hydraulic circuit: Reduced fluid turbulence for smoother operation and lower noise emissions

3. Enhanced Efficiency & Reliability

• Higher overall efficiency: Direct drive eliminates coupling losses (typically 3-5%)
• Reduced maintenance: Fewer components mean fewer points of failure and simplified service
• Improved heat dissipation: Motor cooling system efficiently removes heat from both motor and pump
