D,DY,DG Series Model Horizontal multistage centrifugal pumps is suitable for conveying water. (including the miscellaneous quality is less than 1%, particle size is 0.1 mm). Physical and chemical properties similar to Yu Qingshui other liquid.
DG multistage centrifugal pump medium temperature does not exceed 105 ℃. Suitable for small hot water boiler feed water or similar, and so on.
Transportation: 6.3-540 m3 / head: 50-650 – m
Mechanical seal washing water pressure is generally higher than sealed chamber 0.07 ~ 0.1 MPa pressure.
The medium temperature of 80 ° C or less.Just answer the bearing seal washing water cooling water and machine (packing seal water). Medium temperature at 80 ° C to 110 ° C.Just pick up the packing room (mechanical seal chamber). Mechanical seal washing water, bearing external cavity cooling water cooling water. All media in 110 ° C or higher temperature, cooling water must be connected.

DG Model Horizontal Multistage Centrifugal Pump 
D Series Horizontal Multistage Centrifugal Pump
D,DY,DG Series Model Horizontal multistage centrifugal pumps is horizontal single suction multistage sectional centrifugal pump, owned 6 national patents, and with high efficiency, wide performance, steady and safety operation, low noise, long operation, easy installation.
It can deliver the medium with solid particles(the diameter of solid particles should less than quarter of the impeller channel), besides, it can be changed the pump materials(or flow channel materials), seal way, add cooling system to deliver the related medium, like hot water, oil, corrosive liquid, and abrasive medium.
series horizontal multistage pump using temperature range is -60°C~400°C. Material: HT200, QT600, JM3, 28# alloy, 304, 304L, 316L, 317L, 904IL, CD4, hastelloy B for client’s widely choosing.
D DG DY Series horizontal multistage pumps advantage
1.Low noise,less easy-wearing parts and easy for maintaining.
2.No balance plate,so wider performance range.
3.5%-15% higher efficiency than the old style common multistage pump.
4.Directly coupled, vibration proof and low noise.
5.Circulating flow cooling ensure mechanical seal long life.
6.Excellent seal that is no leakage.
7.work steadily and safety.
