Product Description
Mechanical Diaphragm Metering Pump
The mechanical diaphragm metering pump is a positive displacement reciprocating dosing pump engineered for precise, continuous, and adjustable liquid metering across diverse industrial applications. Unlike hydraulic diaphragm metering pumps, this model employs a direct mechanical drive system where the motor activates an eccentric crank and connecting rod mechanism, converting rotary motion into linear reciprocating motion. This action directly propels the flexible PTFE diaphragm to facilitate fluid suction and discharge cycles without hydraulic oil transmission.
Performance Specifications
This pump delivers stable dosing performance with a steady-state metering accuracy of ±2%. It supports stepless flow adjustment from 0% to 100% during both operation and standby modes. The integrated oil-immersed lubrication system ensures smooth operation, minimal noise, extended service life, and simplified maintenance requirements.
The modular pump head design incorporates highly corrosion-resistant PTFE diaphragm and pump body materials, enabling reliable handling of various corrosive, viscous, and non-abrasive chemical fluids. With its compact structure, minimal installation footprint, and exceptional operational stability, this mechanical diaphragm metering pump fully complies with international industrial standards including API 675 and GB/T 7782.
Core Advantages
- Direct mechanical diaphragm drive with simple, reliable structure and low failure rate
- Precise and repeatable metering with ±2% accuracy
- Full-range 0-100% infinite flow regulation
- Excellent corrosion resistance for diverse chemical media
- Low maintenance cost with stable continuous operation
- Compact layout for easy installation and commissioning
Industrial Applications
Widely utilized in chemical dosing, water treatment, wastewater treatment, petrochemical, power plant, pharmaceutical, and fine chemical industries. This pump provides cost-effective, high-reliability liquid metering and dosing solutions for conventional medium-pressure working conditions.
