Structure: the ZWD type self-priming emergency pump engineering and technical personnel of the Company's domestic and foreign technology, combined with the actual situation of China's mechanical and electrical industry successfully developed. The pump impeller and pump body structure, you can like a general self-priming pump as required to install the bottom valve, but also through the sewage of large particles and long fibers. The pump is the successful development of the market, many customers use to prove its parameters to meet the design requirements. However, in order to further improve the intrinsic quality of the pump, the company in 2003 to greater improvement, so that the inherent quality and appearance quality of the pump to the next level. The pump is specially designed for marine self-priming pump for the emergency fire design is widely used in oil tankers, cargo vessels, environmental protection, pharmaceutical, chemical industry, urban construction, municipal and other industries.

Conditions of Use:

1, ambient temperature <65 ° C, medium temperature <65 ° C, special requirements can reach 160 ℃.

2, the medium pH value of cast iron pump 6-9, stainless steel pumps, 1-14.

Capacity, the particle diameter of 60% of the diameter of the pump, the concentration of 5%, fiber length is generally five times the pump diameter, the concentration of 3%.

Impurities in the medium should be less than 15%.

5, the pump can be used for concentrated pump the use of medium specific gravity of not more than 1240 kg / cubic meter.

6, self-priming pump height can not exceed the nameplate value, the sum of the length of the suction pipe should be <10 m is appropriate.

Special Note: The pump impeller structure unique, the use of low lift pump flow capacity, citing the motor heat, impact, you are requested customer order selection of the appropriate specifications of the pump according to the actual head. In addition, in use when the motor temperature did not exceed 80 ℃, continuous use, customers do not have to worry about. The Company's manufactured products according to national GB3214-82 "," GB3216-82 "C-level accuracy of detection, after passing the factory.
