Working pressure P ~ 15.0MPa
Operating temperature T. 80'C~ +180°C
Design Features
◆Middle section shell: The middle section shells are sealed with O-rings (metal corrugated tooth composite gaskets can be used in special requirements), and the outside is fixed with threaded bolts, which is safe and reliable.
◆Balance mechanism: Most of the axial force generated by the multi-stage impeller is balanced by the balance drum, and the rest is borne by the thrust bearing.
◆Support: According to the temperature of the conveying medium, you can choose foot support or center support (greater than 150"C, ZTM80 and above specifications)
◆Bearing: The standard configuration is rolling bearing, which is lubricated by thin oil, which is safe and reliable and has a long service life. Sliding bearing design is available, and the bearing chamber can be air-cooled or water-cooled.
◆Shaft seal: packing seal, mechanical seal and necessary auxiliary devices can be equipped according to the condition of conveying medium. The shaft seal only bears the inlet pressure, the operation is safe and reliable, and the shaft seal cavity can be water-cooled.

The ZTDS pump needs to use a vertical drive, and the thrust load of the pump and the weight of the rotor will be supported by the thrust bearing of the pump.


The pump is a single-stage, horizontal, radial partial flow pump (also called a tangential pump), which is a special centrifugal pump. Adopt bracket structure, single suction fully open impeller, axial suction and tangential discharge. Packing seal, single-end mechanical seal or double-end mechanical seal are used according to the conditions of use, and are equipped with cooling, flushing or sealing liquid systems, and the rated pressure levels of the suction and discharge flanges are the same. Viewed from the motor end, the pump turns counterclockwise.


This pump is suitable for conveying clean or particle-containing liquids, low-temperature or high-temperature liquids, neutral or corrosive liquids.
