Horizontal Centrifugal Pump

Horizontal Centrifugal Pump

YYW series horizontal centrifugal pump is of single stage and single suction in keeping with the ISO2858 requirement. It is an optimized product on basis of YYG series vertical type product, which can fall into more than 250 types of specifications like basic type, flow expansion type, A, B, C cutting type and so on.

Main Technical Parameters
Flow 1.5-2400m3/hr
Head 8m-150m
Conditions of Use
Maximum working pressure ≤1.6MPa
Ambient temperature ≤40℃
Relative humidity ≤95%
Media temperature ≤80℃
Media volume ≤0.1% of the unit volume
Media granularity <0.2mm
Minimum liquid level for operation You had better consult the related description about motor cooling system in installation diagram.
Rated voltage 380V
Rated frequency 50Hz
Deviation of both rated voltage and rated frequency for normal operation ≤±5%
Maximum diameter of solid particles It must be no more than 50 percent of the pump outlet diameter.

Note
1. Media of pure water pump must be non corrosive liquid with the media temperature of at most 80℃. Besides, the media solid should be insoluble with its granularity of less than 0.2mm and its volume not exceeding 0.1 percent of the unit volume. You had better tell us when placing the order, once the media contains fine granules.

2. You might as well propose it when placing the order, when the pump working pressure is above 1.6MPa or the inlet pressure is over 0.4MPa. Thus, we can change to use cast steel materials for the wet parts of pump.

Characteristics
Prominent characteristics of this horizontal centrifugal pump include compact structure, small floor space, elegant appearance, reliable operation, long service life, convenient installation and maintenance, low noise, high component concentricity and no leakage. Besides, the pump impeller possesses outstanding static and dynamic balance without vibration. By adoption of anti corrosive and hard alloy type mechanical seal, we can well solve the severe problem of packing seal leakage of our product. There are three types of optional outlet direction to install our product, including horizontally to the left, vertically upwards and horizontally to the right.

Applications
This horizontal centrifugal pump can be applicable to water transportation for long distance, heating, ancillary equipment, cold or warm water circulating in bathrooms, pressurized water supply in tall buildings, garden irrigation, pressure boost for fire protection, water supply and drainage in both industries and cities etc. Also, it is suitable for transporting pure water or other similar liquid with the media temperature of below 80℃.

Horizontal centrifugal pump is made up of pump, motor and base. Pump includes body, impeller, cover, mechanical seal and other spare parts. Both the body and cover are divided from the back of impeller. Most impellers are equipped with sealing ring. Also, we set a balance hole on the back plate of impeller. Pump is coaxial with motor and the motor can bear the residual axial force by adoption of angular contact ball bearing structure. Moreover, the pump is directly connected with motor in no need for correction during installation. Thanks to the anti vibration pad, our product can be separated from vibration. To sum up, it is flexible and simple to install our product with a variety of installation methods.

As a specialized horizontal centrifugal pump manufacturer and supplier in China, B-TOHIN also provides mechanical screen, roots blower, industrial submersible pump, and low noise rotary blower, among others.
