CXD(P), DF(P), MD(P), DG(P), DY(P) self-balancing horizontal multistage centrifugal pump

CXD(P), DF(P), MD(P), DG(P), and DY(P) series self-balancing horizontal multistage centrifugal pumps (self-balancing type). The first stage is a single suction or double suction multistage structure. This series of products is an innovative product designed to micro-accelerate the development of multistage centrifugal pump technology. On the basis of meeting user needs and absorbing advanced technology from various countries, combined with the company's years of research and development experience. The product performance reaches the advanced level of similar products in the industry and is a good substitute for ordinary multistage centrifugal pumps.

1. Model significance

For example: D(DG, DF, DY, MD)450-60 X 6(P)

D: Represents horizontal multi-stage clean water centrifugal pump

DG: Represents horizontal multistage boiler feed

DF: Represents corrosion resistant horizontal multistage centrifugal pump

DY: Represents horizontal multistage centrifugal oil pump

MD: Represents wear-resistant horizontal multistage centrifugal pump for mining

450: indicates that the design point flow rate is 450m³/h

60: indicates that the single-stage lift at the design point is 60m

6: Means that the pump stage is 6

(P): Self-balancing structure
