1. Sludge dredging pump are designed for continuously handling the most difficult higher abrasive slurries which contain too big solids to be pumped by a common pump. Such as dredging, suck gravel in the dredger, suck gravel in the course of rivers or lakes, delivering slurries in mining, explosive sludge in metal smelting.( type znh pumps are of high-head ones )
2. Sludge dredging pump are widely used to dredger and dam in the rivers, ports and wharf over our country, such as changjiang river, huanghe river, liao river, and zhujiang delta. And also widely used abraoad, such as middle east, europe.
Zidong pump of type zg, zgh gravel pumps are designed for continously handling the most
Difficlut higher abrasive slurries which contain too big solids to be pumped by a common pump.They
Are suitable for delivering slurries in mining, explosive-sludge in metal melting, dredging in dredger
And course of rivers, and other fieldas. Type zgh pumps are of high-head ones.
Construction of this pump is of single casing connected by means of clamp bands and wide wet pas-
Sage.The wet-parts are made of ni-hard and high chromium abrasion-resistance alloys.The dischar-
Ge direction of pump can be oriented in any direction of 360.This type of pump possesses the adv-
Antages of easy installation and operation, good performance of npsh and abrasion resitance.
1. Advanced hydraulic model, cad 3d design, high efficiency and obvious energy-saving
2. Large dredging depth, high density of dredging mud, good npsh and strong suction lift ability
3. Strong through-put. The pump can presistently discharge gravel, high plastic soil lump, etc.
4. The pump can be directly matched with either motor or diesel engine
5. Wide application. It can be used in various kinds of soil quality. Generally, the pump is matched
With an impeller with 3 or 5 pieces of vane. At the same time, the impellers can be provided with
Various diameters and vane types to suit kinds of working condition.
6. Little hydraulic loss, high efficiency and low oil-consumption
7. Little volume, light weight
8. Steady operating, little vibration, low noise
9. Simple & reliable constrution, easily disassembly & assembly, convenient maintaince
10.Reliable sealing without leakage
11.Long operating life of parts.
A) the zg sand pumps are designed for continuously handling the most difficult higher abrasive slurries
Which contain too big solids to be pumped by a common pump. Such as dredging, suck gravel in the
Dredger, suck gravel in the course of rivers or lakes, delivering slurries in mining, explosive sludge in
Metal smelting.( type zgh pumps are of high-head ones )
B) zg dredge pumps are widely used to dredger and dam in the rivers, ports and wharf over our country,
Such as changjiang river, huanghe river, liao river, and zhujiang delta. And also widely used
Abraoad, such as middle east, Europe.
