HPLC P1/P2/P4 Pump
The HPLC P1/P2/P4 Pump cam, crafted from high-hardness alloy steel with high-frequency heat treatment, boasts a wear-resistant surface exceeding 55HRC hardness, extending its service life. Coupled with a high-power customized motor, Japanese NSK bearings, and an independent air duct, this setup enhances both power and durability for superior performance and longevity.
Precision
Excellent repeatability
We ensure precise gradient changes and retention time through the reciprocating tandem plunger pump and a pressure dynamic suppression algorithm. The retention time's repeatability is less than 0.2%.

Reliability
The reliable design makes service life longer
Material
The cam undergoes integral processing using high-hardness alloy steel, coupled with high-frequency heat treatment technology. This process enhances the cam's surface, making it more wear-resistant (with a hardness above 55HRC) and extending its service life.
Power
The use of a high-power customized motor, Japanese NSK bearings, and an independent air duct further enhances both the power and lifespan of the equipment.
Gearing
We utilize self-lubricating and wear-resistant materials imported from Germany for the piston drive mechanism. Additionally, the inner wall rifling design serves to prevent accidental piston locking, ensuring more reliable gearing.
Plunger
The patented suspended floating plunger (Patent Number: ZL 2020 2 1896102.3) adjusts automatically to various working conditions, offering convenient disassembly and effectively preventing eccentric wear of the sealing ring. Featuring a special sealing structure and automatic plunger cleaning, the pump seal becomes more reliable.
Ease of use
Equipped with an online automatic rinsing mechanism
During pump operation, the rinsing pump activates automatically at intervals. This process effectively prevents buffer salt crystallization, microbial growth, and extends the service life of both the plunger and its sealing.
Easy to purge
Both the workstation and instrument panel feature a purging function, simplifying the purging process.
Easy to Intelligent solvent switching to improve efficiency
Featuring a 4-channel solvent selection valve for the binary pump, the solvent can automatically switch based on the method being used.
Independent 4-channel gradient proportioning valve, easy for maintenance
The quaternary pump's gradient proportioning valve uses a four-channel independent design. Intelligent monitoring and diagnosis enable real-time tracking and independent replacement of each channel. This overall design effectively minimizes maintenance costs.
