Since the company's products have already been recognized by the national authorities, why does the local technical supervision bureau have to test it again? According to insiders, the local technical supervision department has done so, it has to pull the local quality inspection department. It turns out that local quality inspection institutes have annual revenue-generating targets, but the quality inspection institute does not have enforcement power, and the source of income can only be inspection fees. However, many companies do not buy the accounts of quality inspection agencies. Directly going to companies for random inspections and charges is often rejected. The local technical supervision department has just the right to enforce the law and can force the company to take random inspections. So the two companies worked together: the technical supervision department went to the company for sampling fees, the samples were sent to the quality inspection department for inspection, and the quality inspection institute issued a report for a further fee, and the two companies were well-qualified.
Undoubtedly, such tests are detrimental. Not only does it increase the burden on companies, but it also seriously affects the credibility and image of law enforcement agencies. At the same time, this kind of behavior is easily used by unscrupulous companies, leading to confusion in the market order. Because the purpose of the test is to generate revenue, the degree of concern about the quality of the product will naturally be reduced. As long as the company pays enough money, even if the product quality is unqualified, it can get a report of qualified testing. Unqualified products rely on money to clear the way, to successfully enter the market, the market can not mess it?
Market economy is essentially a legal economy, order economy, and regulatory economy. The first thing that should be regulated is the management of various levels of government. It is the key to the normal operation of the entire market economy because these departments can do their jobs according to the law rather than rely on personal interests. When these departments come to chaos, they are all chaos.
I hope that the strange phenomenon of two test reports for a product can disappear as quickly as possible. However, management departments that wish to enforce their own interests will no longer behave like this. I hope all companies can survive and develop in a strong regulatory environment.
Pump Cover is a main part of Dredge Pump
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.

Single-Walled Dredge Pumps
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.)
Cast pieces group C (Construction) :
Other pieces as pivots, rod eyes, wire sheaves etc.
