Xu Ruisheng, deputy governor of Guangdong Province, held a promotion meeting for the elimination of yellow-label vehicles in some cities in Guangzhou, and researched and deployed to speed up the progress of the elimination of yellow-label vehicles in our province.
Xu Ruisheng emphasized that the elimination of yellow-label vehicles is an important measure to improve air quality. Local governments and provincial departments should further enhance their understanding, cooperate closely, enhance their sense of responsibility and urgency, and effectively increase their efforts to eliminate them.
According to the province's motor vehicle environmental protection database, from January to September 2015, the province eliminated a total of 392,201 yellow-label vehicles, and completed 81.52% of the province's annual phase-out plan; and eliminated the operating yellow-label vehicle 12.0405 registered before the end of 2005. Ten thousand vehicles completed 72.9% of the province's elimination plan in 2015. The progress of the elimination of yellow label vehicles in the whole province was generally smooth, and the phase-out progress of some cities was behind schedule.
Pump Liner is a 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.
