Introduction to Pump Drives & Control Systems

Modern pumping systems require more than just high-quality pumps — they need intelligent control and drive systems to operate efficiently, reliably, and safely. Caprari offers a comprehensive range of drives, control panels, and protection systems designed to optimize pump performance, reduce energy consumption, and extend equipment life.

At Modern Machinery, we provide the complete Caprari drives and control range in Egypt.

CAPDRIVE – Frequency Converter

The CAPDRIVE is Caprari’s advanced frequency converter (VFD) designed specifically for pump control applications.

  • Type: Variable Frequency Drive (VFD)
  • Power Range: 0.75 kW to 630 kW
  • Control Mode: Sensorless vector control, V/Hz control
  • Protection: Overload, overvoltage, undervoltage, short circuit, earth fault
  • Communication: Modbus RTU, Profibus, Ethernet (optional)

Benefits:

  • Energy savings of 30–50% compared to fixed-speed operation
  • Soft start and stop reduces mechanical stress on the pump
  • Precise pressure and flow control
  • Built-in PID controller for constant pressure applications
  • Comprehensive motor and pump protection

Applications:

  • Constant pressure water supply systems
  • Variable flow pumping stations
  • Booster sets and pressure boosting
  • Irrigation systems with variable demand
  • Wastewater pumping with variable inflow

Electric Panels – Control & Monitoring

Caprari electric panels provide complete control and monitoring for pumping stations, from simple single-pump control to complex multi-pump systems.

  • Types: Direct-on-line (DOL), Star-Delta, Soft Starter, VFD panels
  • Features: Pump alternation, level control, dry run protection, phase failure protection
  • Monitoring: Current, voltage, power, flow rate, pressure, temperature
  • Communication: Remote monitoring via GSM, SCADA integration

Available Configurations:

  • Single pump control panels
  • Multi-pump control panels (2–6 pumps)
  • Fire fighting pump panels
  • Wastewater pump control panels
  • Custom-engineered solutions

VSD – Variable Speed Drive

Caprari’s variable speed drives offer robust and reliable speed control for pump motors in demanding applications.

  • Power Range: Up to 630 kW
