Filter feed pump

I. Introduction HFM series without leakage corrosion resistant filter press pump is a new type of rear suction liner (shaft sealing position with the inlet in the same direction) of corrosion resistant filter pumps. The filter press pump is a summary of the general corrosion resistant pumps, a new type of pressure at run time, the seal prone to leaks developed pump case, where the application of the five innovative technology (patent). Its main features are: a pump inlet port in the same direction as the shaft seal, the shaft seal is under negative pressure environment, it will not leak, corrosion resistant pumps to overcome the existing fragile, easily shaft seal leakage solid disease . Second wide range of applications: the filter press pump a wide range of interchangeable lining material, can be applied to various chemical properties of corrosive, abrasive slurry serum and transportation, and a variety of spare parts of different materials exchange Good performance, user adjustment is extremely convenient. Third, low operating costs: There are two main factors, one is the vulnerability of the pump cover and the suction port such as the use of split-type structure, with a separate corrosion resistant wearing parts, easy to replace, more economical. Second, do not use the back of the pump impeller vacuum seal, the shaft power consumption saving, saving energy. Four further advantage HFM-II-type two-stage pressure filtration corrosion resistant slurry pump are: wear resistance, because a single lower impeller speed, to obtain higher pump outlet pressure, thereby overcoming the single stage slurry pump impeller to increase the pressure and increase line speed, which led to the disadvantage of the impeller, the pump casing wear and tear, and effectively improve the life of the impeller, the pump cover and other wear parts. Five. HFM-II-type two-stage pressure filtration pump corrosion resistant due to the high pressure, when equipped with the high-pressure filter press, filter effects, small cake moisture, insufficient to overcome the filter pump is equipped with pressure shortcomings. Second, the scope 1. This series of corrosion resistant filter press pump can transport all kinds of corrosive and non-corrosive clear liquid and slurry temperature is 100 ℃ within various types of filter pressure or as a feed pump, For example: non-ferrous metals zinc, copper, cobalt, nickel, manganese and other hydrometallurgical processes filter press equipped with a pump or process pumps, mining mineral processing, non-metallic mineral processing (titanium dioxide, kaolin, etc.) process in slurry pump, environmental protection industry in the sludge, waste pumps, other chemicals, dyes, pharmaceuticals, food production process filter press pump or pressure pump. II. Long-term force pressure operation (pump outlet pressure is high) Conveying post corrosive media, such as flue gas desulfurization, air control pressure spray pump, pressure washer pumps. III. When the other pumping medium, prone to leaks positions. IV. The filter press pump single-stage and two-stage two series, to meet the needs of small flow of high pressure transport corrosive slurry jobs. NA Post: liquid level below the pump suction port position 1.2m or less, or the inlet suction is too large positions.
