Overview
This series of pumps is a horizontal single suction multi-stage segmented centrifugal pump with 6 national patents. It has the advantages of high efficiency, wide performance range, safe and stable operation, low noise, long service life, and easy installation and maintenance.
It can be used to transport media containing solid particles (particle diameter less than one fourth of the impeller channel), and can also be used to transport hot water, oil, corrosive or abrasive media by changing the material of the pump (or the material of the pump's flow passage), sealing form, and adding a cooling system.
The operating temperature of the ZD, ZDG, ZDF, ZDY, ZMD series horizontal multi-stage centrifugal pumps is -60 ℃~400 ℃. Various materials are available for users to choose from, including HT200, QT600, JM3, 28 # alloy, 304, 304L, 316L, 317L, 9041L, CD4, Hastelloy C, Hastelloy B, etc.
Our company has passed the IS09001:2000 quality system certification, and our product design, production, and service have strict and standardized control systems, ensuring sufficient product quality assurance.Parameter range (design point)

Model Description
ZD (ZDG, ZDF, ZDY, ZMD) 46-30x4
ZD - represents a self balancing multi-stage clear water centrifugal pump
ZDG - stands for self balancing multi-stage wear-resistant centrifugal pump
ZDF - stands for self balancing multi-stage corrosion-resistant centrifugal pump
ZMD - stands for multi-stage wear-resistant and corrosion-resistant centrifugal pump for self balancing coal mines
46- indicates a design point flow rate of 46m 3/h
30- indicates a single-stage lift of 30m at the design point
4--Indicating a level of 4Structural characteristics
1. The impellers of ZD, ZDG, ZDF, ZDY, and ZMD horizontal multi-stage centrifugal pumps are symmetrically arranged, which can basically eliminate axial forces. The residual axial forces are borne by a pair of back-to-back angular contact ball bearings. Due to the absence of a balancing device, which includes both disc friction loss and reflux loss, the pump efficiency is increased by 5-14% compared to multi-stage pumps of the same category. At the same time, it completely solves various pump failures caused by the failure of the balancing device, greatly extending the service life of the pump.
2. Adopting high-end sealing: Traditional multi-stage pumps used in mining use packing sealing, which has the advantage of being resistant to particle impurities, but there are leakage problems during use. Mechanical seals have no leakage, but their service life is very short when used in media with particle impurities. The new multi-stage pump for mining produced by our company adopts a high-end seal, which combines the advantages of packing seal and mechanical seal. It can be used for a long time in media with particle impurities without leakage. This seal is a new patented high-end seal developed by our company that is resistant to particle impurities
Sealed. 3. The bearing seat never gets water: This technology is a newly developed patented technology by our company, which ensures that no liquid enters the bearing seat during use and at rest, further extending the service life of the bearing and reducing maintenance costs for users.Structural diagram
