Key Features & Benefits:
Fully Automatic Operation: PLC-based control system with intuitive HMI allows for precise dosing adjustments, alarms, and remote monitoring. Reduces manual intervention and human error.
Plug-and-Play Design: Pre-assembled on a compact skid, including pump, piping, valves, instruments, and control panel. Only requires connection to power and process lines.
Designed for NACL > 89% Purity: Optimized for hydrochloric acid produced from high-purity salt, ensuring consistent performance and minimizing scaling or corrosion issues.
Economic Operation: Energy-efficient metering pump technology and intelligent control algorithms reduce chemical waste and power consumption, lowering total cost of ownership.
Corrosion-Resistant Materials: All wetted components are made of high-quality plastics or stainless steel, offering excellent resistance to hydrochloric acid.
Customizable Configurations: Flow rate, pump type, material, and additional features (e.g., flow meters, pH feedback, remote communication) can be tailored to your specific process.
Safety Features: Includes leak detection, emergency stop, pressure relief, and low-level alarms to ensure safe operation.
Detailed Product Description:
The core of the skid is a high-precision metering pump, either diaphragm or piston type, driven by a variable frequency motor. The pump is paired with a pulsation dampener, calibration column, and backpressure valve to maintain stable dosing. The control system automatically adjusts the pump stroke length and frequency based on setpoint or external signals (e.g., 4-20 mA from a pH sensor). The HMI displays real-time flow rate, totalized volume, alarms, and system status. All data can be logged and exported via optional RS485 or Ethernet communication.
The skid is designed for easy maintenance: all components are accessible, and the calibration column allows quick verification of dosing accuracy. The entire unit is mounted on a heavy-duty stainless steel frame with forklift pockets, facilitating transportation and installation. We provide a complete documentation package including P&ID, electrical schematics, and operation manual.
