dredge pumps ranging from inlet diameters of 400mm up to 1400mm. Our CFD optimized pumps have an excellent suction performance, high efficiency, long wear life and require a minimum of maintenance. The pumps can be delivered in different types of wear resistant materials, and can be executed in a large number of different configurations.

Why are companies unwilling to be transferred to local management? The author learned from the survey that chemical companies have many worries about this.
If there is a concern for the management of the city, can the coordination ability of the local government meet the production needs of chemical companies? The production of chemical companies has the characteristics of “large in and large outâ€, raw material procurement and product sales cannot be separated from the railway lines of thousands of miles, and some are also divided across several railway bureaus. In recent years, the bosses of chemical companies have suffered from the strain of raw material procurement and rail transportation. In the past, when they were in an emergency, they were able to solve the problems through the coordination of the relevant provincial departments. If they are transferred to the prefecture-level city management, they will lose such coordinating advantages at the same level, making the company's raw material procurement and railway transportation tense. Adding to the frost.
Second, if the city's management is demarcated, will the company become Tang Yanrou? Some chemical company executives lamented that in the past when the business was difficult, local business departments rarely saw assistance. If they are actually handed over to them, the people, expenses, etc., which were previously difficult to achieve, will now be justified and easy to change, and the company will probably become one of those who will be killed.
Three worries If you transfer to city management, corporate reputation will not be discounted? The level of affiliation of provincial enterprises is relatively high, and their contacts are relatively wide. As a result, their external reputation is high. After transferring to the city, they think that the intangible assets of the company will be damaged, which is not conducive to the development of the enterprise. The employees are reluctant to accept from the bottom of the heart.
Enterprises do not want to transfer to the city management to make people think deeply. The reform of state-owned enterprises is imperative. The transfer of enterprises to the management of cities and cities is conducive to the macro guidance of provincial governments. However, we must not forget that once glorious Dongfeng Tire Co., a year ago, it ended up with a "waiting for price". Although there are various reasons for the decline of Dongfeng Tire, its frequent replacement of her mother-in-law is one of the reasons. It can be seen that frequent exchange of “mother-in-law†is not a good thing, and “grandmother†is replaced by “mother-in-law†is not a good thing.
single-walled dredge pumps are `all-round` and used in all types of dredgers. They are designed for typical pump pressures up to 16 bars, and can be excecuted with different types of pump seals such as: stuffing box, mechnical seal or hydro seal.
Double-Walled Dredge Pumps
double-walled dredge pumps are specially designed for high pressures, starting typically from 16 up to 30 bars. The double-walled pump design is based on the concept of pressure compensation between the outer-, and inner-pump casing. All types of configurations are possible such as 3,4 and 5 vane impellers, and casted or welded outer-casings.
Underwater Dredge Pumps
The underwater dredge pumps are used in cases where the highest possible suction performance is required. They basically have the same possibilities and options as our single-walled pumps have. Depending on our clients' preference they are executed with direct motor drive or integrated gearbox, with or without pressure compensation.
Casting
1)Pattern
Collection in our storehouse. Inspection of pattern in our workshop.
Pieces cast with wrong pattern due to insufficient inspection of pattern are rejected.
Free delivery of pattern (in good condition) with last cast piece of order to our client or stored in our workshop for future new production but with time-limited or quantity-bound.
2)Cast pieces
Material
The use of the cast pieces requires other chemical analysis and mechanical properties (unless otherwise mentioned on drawing).
Cast pieces group S (Wear) :
Impellers, pumphousings, dredge lines (bends, branchpipes, etc.)

Corporate Perspective: Why Enterprises Are Concerned about the Management of the City
On the eve of the National Day, 21 provincial enterprises, including five chemical companies, were transferred to Baoji City. Last week, another 27 state-owned enterprises were allocated to Xianyang City management, which led to the devolution of Shaanxi provincial enterprises to the local market. The prelude to management. The author noticed that several large chemical companies in the province had heard about the wind before they were ready to find a way out through asset restructuring and corporate restructuring: working closely with large companies such as coal and oil—even if the other party holds shares. Its purpose is self-evident - to rely on "big tree" to get rid of the destiny of the city's management.
