DPX Design Features
- Power End –
- Adjustment Mode- Manual, electrical, pneumatic, frequency converter.
- Adjustment Mechanism- Patented design of integrated sleeve adjustable eccentric mechanism with compact structure, high transmission efficiency, rigid design with high strength for extreme operation, long service cycle, and convenient maintenance; adjustment range from 0% to 100% with stepless adjustment.
DPX Design Features
- Power End –
- Integrated worm gear with low noise, high efficiency with low energy consumption, large torque, low maintenance cost and long service life.
- Fluid End –
- Built-In Pressure Relief Valve- No external flow line reduces leakage, minimize hydraulic space from over pressure, and protects safety operation.
- Check Valve Assembly- Provide quality metering accuracy; the design of check valve meets requirement of all working conditions. Ball valve, flat valve and cone valve are also available.
- Limit Valve- To prevent hydraulic space from excessive oil supply, avoids excessive deformation of diaphragm, and provide prolong service life of the diaphragm.
- Diaphragm- PTFE or Teflon, multi-directional rolling and quenching treatment enhances tenacity of the diaphragm with rigid design for prolong service operation. Single diaphragm, double diaphragm, and triple diaphragm are available.
- Pump Head- High pressure design and protects diaphragm effectively and provide smooth operation.
