TSWA Horizontal Multistage Centrifugal Pump

TSWA type horizontal multistage centrifugal pump,and it is characterized by its high efficiency,fine NPSH,low vibration,low noise and stable operation,etc.It is recommended the most reasonable product in the area of high-rise water supply,fire water and heating by various Design Institutes in China.The temperature of the transported liquid is less than 80ºC.
Availability:
Quantity:

TSWA type pump is multistage sectional centrifugal pump.Its inlet is placed horizontally at the inlet section,and its outlet is placed vertically upwards at the outlet section.The customer can select different types of pump in accordance with the different requirement on head.The pump stator is mainly made up of inlet,middle,outlet section,tail cover and bearing body,etc.The pump rotor is made up of pump,impeller,shaft sleeve and balance plate,etc.The joint face of inlet,middle,and outlet section is sealed with paper pad.The asbestos is used to seal between shaft sleeves so as not to let water enter the bearing along the shaft.The stuffing seal is used in the shaft seal of two ends of the pump.Through the adjustment on tightening bolt,the liquid then can leak out drop by drop.The bearing adopts rolling bearing,and calcium solid lubricant is applied inside the bearing.The pump rotates clockwise from the direction of drive end.

Applications
1. Mainly used in high buildings life water supply, fire fighting system, automatic spraying water under the water curtain, long distance water transportation, water circulation in production process, supporting the use of all kinds of equipment and various production process water, etc
2. It is used in city construction, factories, mines, the water is especially suitable for hotels, restaurants, entertainment refrigeration and air conditioning supply water.

1. This series pump is a horizontal, single suction, multi stage centrifugal pump section, the suction is in horizontal direction, and outlet is vertical upward. Water suction, middle, discharge section, bearing housing and pump body are bolted into one strain, and select stages according to the pump head.

2. Rotor includes shaft, impeller, shaft sleeve, balance disk, and other parts. Axis parts are connected through the flat keys and the shaft nuts. The rotor is supported by the rotor bearings or sliding bearings in both ends, the bearing does not bear axial force, axial force is balanced by the balance disc. Bearings lubricated with grease, sliding bearings lubricated with light oil, and oil ring lubrication, and cooled by circulating water.

3. Shaft seal in the form of two kinds, mechanical seals and packing seal. When use packing seal, the packing ring should be placed at the right location, the tightness of packing must be appropriate to the liquid oozing drop by drop. Various sealing elements is in a sealed chamber, the chamber must be filled with some water, as water seal, water cooled or water lubrication. At the seal there is replacable sleeve, to protect the shaft.

4. From the motor direction, the pump is clockwise rotation.

Classification and difference of submersible pumps

The hot water submersible pump is used for hot spring bathing, and can also be used for extracting groundwater from deep wells, and can also be used for water lifting projects such as rivers, reservoirs, and canals. It is mainly used for farmland irrigation and human and animal water in high mountain areas. It can also be used for central air conditioning cooling, heat pump units, cold pump units, cities, factories, railways, mines, and construction site drainage. The general flow rate can reach 5~650m³/h, and the head can reach 10-550 meters.
