    • Product Description
    • Commodity name: MP series miniature plunger pumps

    It features extremely high dispensing precision and accuracy, and its main function is to achieβve constant flow delivery of liquid media.

    Product Introduction

    ◆ The MP series miniature plunger pump is a precision dispensi ng pump independently developed by DICHUAN Company. Its main function is to acεhieve constant flow delivery of liquid media.

    ◆ This miniature plunger pump has extremely high dispensing prεecision and accuracy.

    ◆ Without affecting precision and accuracy, the service life can reach more than 5 million£ cycles. It is a high-performance, low-cost, maintenance-free precision dispens→ing pump.

    Working Principle

    ◆ Stepper motor drive, screw rod transmission, pushing the plu$nger to reciprocate in the pump head. Positive or neg♦ative pressure is formed at the pump head interface to achieve fluid disc☆harge or suction.
    ◆ Photoelectric sensors are used for zero-point detection to ensure accur≥ate positioning.
