Jingjin Intelligent Energy-Saving Feed Plunger Pump: Features and Innovative Advantages

1. Wear Resistance:The plunger is made from alumina ceramic and fired to achieve a hardness above HRC8.5, with a surface roughness of 0.4μm. After fine grinding, it exhibits excellent wear resistance, especially for materials containing sand and solid particles, as there is no shear movement between the plunger and the conveyed material.
2. Strong Self-Absorption Ability:The plunger operates in a vacuum mode, providing a self-priming capacity of 4-8 meters. The specific gravity of the materials determines the variation in the suction range.
3. Compact Design:The pump features a built-in plunger cylinder structure, making it shorter than conventional vertical plunger pumps. The integrated cooling channel ensures no leakage of circulating water, keeping the site clean and tidy.
4. Energy Efficiency:Utilizing a large diameter, double-cylinder hydraulic double pump design, the system automatically adjusts the required pressure based on the filter press’s working conditions, achieving high efficiency and energy savings.
5. Intelligent Control:The pump incorporates dynamic pressure acquisition, intelligent flow control, and soft piston reversing, significantly reducing vibration and noise for smooth operation.
6. Simple Operation:Pressure adjustment is straightforward; simply tighten or loosen the pressure regulating valve. Once set, the valve is locked, eliminating the need for further adjustments.
7. Aesthetic Design:The pump body undergoes sandblasting and spray painting processes to relieve stress and ensure the adhesion and aesthetics of the anticorrosive paint.
8. Safety and Reliability:Equipped with a safety pressure sensor, temperature overheat protection sensor, and action timeout alarm, the pump ensures safe operation.
9. Top-Brand Electrical Components:The low-voltage appliances in the cabinet are from Schneider, and the PLC is from Siemens, ensuring high-quality and reliable performance.
10. Versatile Control Options:The pump offers both remote and local control options. Local control is managed via the control cabinet of the piston pump, while remote control can communicate with the filter press’s control cabinet or upper computer through hard wiring, MODBUS, or Ethernet, allowing remote start and monitoring of the piston pump’s running state.
11. High Rated Pressure:The feed pressure ranges from 0 to 2.0 MPa (2.0 MPa to 3.5 MPa should be specified), with a rated water pressure up to 1.8 MPa.
12. Perfect Match for Filter Press Feeding Process:Initial Feeding Stage: The filter press chamber is empty and needs rapid filling. Both large and small displacement hydraulic pumps operate simultaneously to achieve maximum flow.
13. Pressure Filtration Stage: As the filter press fills and pressure rises, the piston pump adjusts to maintain the required pressure, switching to a large displacement hydraulic pump while stopping the small displacement pump.
14. Pressure Holding Filtration Stage: When the feed pressure reaches the highest set point, the pump switches to a small displacement hydraulic pump to save energy while maintaining the required pressure.
15. Low Maintenance Cost:The primary wear parts are the valve plate and plunger seal. The replacement cycle for ceramic mud is every 6 months, and for municipal sludge, it is every 12 months.
16. Long Service Life:The pump is designed to last for at least 15 years.
17. Customized Production:Products are flexibly configured and customized according to each user’s actual working conditions, ensuring they meet specific production needs.
