BWH series chemical heat preservation pump
Pump introduction:
BWH series chemical heat preservation pump is a kind of single stage single suction centrifugal pump with heat preservation jacket. It is improved on the basis of general chemical pump and mainly suitable for conveying the medium at low temperature and easy crystallization or the medium with constant temperature. The pump can use steam or hot water for heat preservation.
As the advanced and scientific and unique pump structure and sealing
According to the different media can use different materials to produce this pump, currently usually A3, 321, 304, 316, 316L, duplex stainless steel and other materials
Performance Range:
Flow rate: 1.6-400 m3 / h
Head: 5-125 - m
Size: 25 - ф ф 200 mm
Specification sheet:
technology, the pump can transport the medium with solid content up to 35%. Under normal conditions, the pump works for 8000 hours without leakage, which is 3-5 times of the sealing effect of general chemical pump. Because the impeller is open structure, it will not be blocked due to the high solid content of the medium. The pump is the most ideal advanced equipment for conveying insulation materials needed by the chemical industry.
