Unipretec Ceramic Filling Pump for Medical Liquid

●Technical Indicators of Ceramic Filling Metering Pump

1. Loading volume: 0.2--50ML;2. Operating temperature: 10~40℃;

3. Filling accuracy standard: when the filling volume is less than 2ML, the upper and lower deviation does not exceed ±1%; when the filling volume is more than 2ML, the upper and lower deviation does not exceed ±0.5%.
The product has been tested for air tightness and installed on the filling machine for filling accuracy test before leaving the factory: the accuracy test method uses pure drinking water as the medium, adopts the gravimetric method to calculate the average value, upper deviation and lower deviation.

● Structure and Principle of Ceramic Metering Pumps

1. The ceramic filling metering pump is composed of ceramic metering components (ceramic pump sleeve, rotary valve, metering rod), stainless steel inlet and outlet nozzles and connectors.
2. Working principle of ceramic filling metering pump:
- The mouth of the rotary valve is aligned with the liquid inlet, and the downward linear movement of the ceramic column generates negative pressure and sucks the liquid;
- The mouth of the rotary valve is aligned with the liquid outlet, and the upward linear movement of the ceramic column generates positive pressure and discharges the liquid.

● Assembly of Ceramic Pump And Connection With Filling Machine

1. Since the ceramic rod and the ceramic sleeve are precision fittings, the gap is small and cannot be interchanged; the products have been numbered before leaving the factory and cannot be interchanged during cleaning and assembly.
2. Before installing the machine, make sure that the sealing parts are installed in place and must not leak.
3. The assembly gap with each part of the filling machine must be eliminated (the assembly gap will cause the stroke to change, resulting in inaccurate measurement), and the coaxiality of the moving parts must be guaranteed (affecting the service life of the pump and the filling accuracy).
