Features
Vertical multistage, sectional, compact and small structure;
Shaft seal is wearable mechanical seal and you can choose removable, leakage is little, operation is smooth and easy to maintain;
Pump body has tube structure, its inlet and outlet size is the same, and that they are at a line, can be fixed anywhere like valve, convenient, fast and steady;
You can choose up-outlet type in order to convenient fixing, the angle between inlet and outlet can be adjusted 0°, 90°, 180°;
The area is small because of special installation structure. 40% investment into building can be saved.
