LQ series colloid pump and other pump difference

1.LQ series gel pump compared with other pumps mainly the following differences: a) LQ series colloid pump is a positive displacement pump, the delivery flow can be more precise control can also be easily made of variable displacement pump. Centrifugal pump output flow can not be controlled, with the resistance of the increase and decline; The pump has a strong self-priming capability, while the centrifugal pump must be filled with liquid before the move. b) LQ series colloid pump speed is very low, usually between 200rmp to 600rmp, the material being delivered is smoothly output and its components will not be damaged. Centrifugal pump speed is high, the material being transported by a strong impact and the role of centrifugal force, so the centrifugal pump in the delivery of the mixture often have different substances in the composition, so that the quality of finished products. The pump is the best solution to this problem, so it is particularly suitable for conveying mixed materials and even the material containing solid particles. c) LQ series colloid pump can be used to transport high viscosity substances, so also called colloid pump. The centrifugal pump without this feature. d) The pump can be easily made of high output pressure species, such as 15kgf / cm2, suitable for long-distance or high-resistance quantitative delivery. 2. Compared with the screw pump (thick pump): both belong to the same type of positive displacement pump, so its performance is basically the same - can steady delivery of high viscosity substances, have a higher delivery pressure. However, one of the biggest drawbacks of a screw pump determines its inapplicability to hygienic requirements - it is not possible to be a hygienic pump due to the non-streamlined surface of the screw pump and the numerous defects in the chamber, Or rubber material damage is more likely to be contaminated by the material being transported. The pump due to the streamline structure of the rotor and the rotor chamber basically no dead spots and non-metallic parts, so strictly speaking in food and beverage, medicine and other health requirements of the industry, the universal pump is more suitable for applications, in particular Today's production lines are becoming more and more automated, with more and more online (in-situ) cleaning (CIP), demonstrating the importance of choosing the Seven-Star gel pump.
