应用范围
普通型适用于液体传输，冷热清洁水，软化水的循环和增压。
不锈钢型亦适用于微碱水、脱矿物质水、蒸馏水、游泳池水及其含氯化物液体，但液体允许温度需要降低。
Scope of application
Common type is applicable for liquid conveying, circulationboosting of hotcold clean water, soft water;
Stainless steel type is also used for water with tiny content of alkali, mineral, distilled water, water for swimming poolsolution with chloride, but the allowed temperature of the liquid shall be reduced.
性能曲线及性能表说明：
1、 所有曲线都基于3×380V，50Hz，电机在恒速2900r/min的测量值。电机为可变电压电机；
2、 测量采用自由空气下20℃的水，运动粘度r=1mm2/s；公差参照ISO2584附件B标准；
3、 泵的使用参照粗曲线的性能范围，以防止过热造成危险。
Explanation to the performance curveperformance table:
1、 All the performance curves are based on the measured values of motor 3×380, 50Hz under constant speed of 2900 r/min. The motor is of changeable voltage;
2、 Measurement is done on the basis of: 20℃ water in free air, dynamic viscosity r=1mm2/sec.; tolerance refers to attachment B of ISO2584
3、 The operation of pump shall refer to the scope of performance of the black curve to prevent danger due to overheating.
