JSR series plunger metering Pump is positive displacement plunger dosing pumps are high pressure pumps with high accuracy performance within ± 1%. The motor can be both vertically and horizontally mounted. Multiplex gear boxes with one motor drive and pump base is available. Pumps produced according to national standards GB7782-2008 or American Petroleum Institute API standards.

1. Driving device
2. Adjusting device
3. Liquid delivery device
Pump flow is determined by the driving speed, plunger diameter and stroke length. Flow rate by adjusting mechanism, (handwheel) to adjust the stroke length to achieve the required flow.
JS series plunger metering pumps include JSX, JSZ, JSR, JSD four products, if more than one series of pump is connected, add the number before the pump model (for example: two JSD connected change to 2JSD).
JS series plunger metering pumps achieve fluid transmission through the inlet and outlet pressure difference. It can be dosed with steady accurancy with the range 30% to 100% . Pump can be adjusted from zero to the max, with repeatability, accuracy ± 1%.
JS series plunger pump can deliver -15 ℃ ~ 120 ℃ liquid. The viscosity of liquid can be 0.3 ~ 1000cps without solid particles.
Different types of metering pumps can be fitted with inverter motor or explosion-proof motor according to the requirements. Model specifications and parameters of the pump, refer to the company’s catalog.
