Products
Shaft-sealless, zero leakage | High-precision quantitative conveying | Strong self-priming acid and alkali resistant chemical quantitative pump
Product Details
1. Four core advantages of the product✅
1. High discharging measurement accuracy: special air bag reciprocating quantitative conveying structure, stroke and speed are controllable in two dimensions, the liquid output flow is uniform and stable, and the error in the proportion of trace pharmaceuticals is small, meeting the needs of precision dosing and metering in electroplating, PCB, and chemical industries.
2. No shaft seal and completely zero leakage: the integral air bag has a sealed isolation structure, without the defects of traditional mechanical shaft seal wear and leakage. Corrosive liquid does not leak out during the entire process, eliminating chemical loss, workshop corrosion and safety hazards.
3. 0.7m high self-priming capacity: It has a strong self-priming function, and the self-priming height can reach up to 0.7M. It can stably absorb liquid at a low position of the liquid storage tank and under tank height conditions. The pipeline layout is flexible and reduces on-site modification costs.
4. Broad-spectrum acid and alkali resistance, long service life of the air bag: the base is made of PP resin, and the umbrella-shaped valve is made of multiple anti-corrosion materials; the air bag is corrosion-resistant and anti-aging, and it is not easy to be damaged when transporting etching liquids and electroplating acid and alkali liquids for a long time, and has a long service life.

💡Remarks:
Multi-connection flow rate = single-head flow rate × number of connections; 2-connection complete machine 2.0kg, 3-connection complete machine 2.3kg;
Parameters are calibrated with normal temperature water. When transporting high-viscosity, highly corrosive liquids, the actual flow rate and pressure will be attenuated by 10%~20%. It is recommended to reserve a working condition margin for model selection;
The standard self-priming height is 0.7M. If the liquid level drop exceeds 0.7m, a front-mounted liquid suction auxiliary device is required.
