Comparation/Feature	6SR	QS, QY and Others Pumps
1 .Multi-Purpose per Pump	Flow of 20-40m3/h	Different pumps with different flow levels
2.Wide-range Flow	No overloading within flow of 20-40m3/h.	Only working at rated flow point. Otherwise electric motors will be overloaded and short-lived.
3.Wide-range Head	Wide-range flow,small changed head	Only working at rated head point. Otherwise electric motors will be overloaded and short-lived .
4.Energy Efficiency	Design of wide head and full flow. Wide efficient areas. 20%~50% less electricity consumption than other pumps in case of deviation of head.	For application far from rated head points, there will be increase 1.2-2 times electricity consumption.
5.Deep Diving	Built-in pressure equilibrator and diving depth up to 150 meters.	Diving depth not exceeding 5 meters.
6.Wind-range Voltage	300V - 420V	360V-400V
7.Anti-sand perfomance	Eightfold performance better than 6SP one	Short-working life with sand-water
8.Compatibility	Motor made as per NEMA standard, matching with various 6-inch pumps.	Low commonality due to integrative structure between pumps and electric motors
