The 3000 series plunger pump is a high precision quantitative plunger pump independently developed by the professional R&D team of Juray. It is widely used in medical, environmental protection, laboratory analytical instruments and other fields. 3000 Series plunger pump adopt precise stepper motor control, precision screw pair transmission, high precision special ceramic plunger, and high polymer wear-resistant sealing enable plunger pump to achieve very precise suction and drainage function in long time and high frequency. It has the characteristics of high precision, stable and reliable operation and long service life. The test results show that the performance parameters of the plunger pump meet the product specifications after running 3 million times continuously and smoothly.

Remark:
Note 1: In addition to the above specifications, the current nominal specifications can be customized, including parameters such as stroke, displacement, screw pitch, thread interface form, etc.
Note 2: Motor current can be customized according to requirements.
Note 3: Special media such as strong acid and base resistance can be customized.
Note 4: The nominal accuracy of suction and drainage is measured at a range of no less than 10% displacement.
Note 5: The nominal repetition accuracy is measured at a range of no less than 10% displacement.
Note 6: The number of threaded ports can be increased or decreased as required, and the lateral port can be adjusted in four directions: front, back, left or right.
