How to choose the type of chemical pump?
Chemical pump products are used to transport a variety of corrosive or flammable and explosive chemical liquids, so the selection of chemical pump is very key before buying chemical pump.
1, first confirm the good chemical pump transport liquid must choose the material of chemical pump and seal material, otherwise because the pump body or seal material can not resist the corrosion of liquid it will cause delays in chemical production and unnecessary economic losses, Therefore, in the process of chemical pump selection, users must inform the pump merchants of the medium name and medium temperature to choose the right chemical pump products.
2, followed by the required chemical pump capacity and head, head make sure good, for the procurement staff it is best to understand when chemical pump selection chemical pump is conveying height, distance, Angle valves and accurate inform chemical pump manufacturer sales staff, in order to choose an appropriate chemical pump model.
3, it is important to note, finally have to confirm a good chemical pump transmission medium density, viscosity and particle impurities, if the weight is too much on the basis of the original chemical pump motor selection more motor power, viscosity is too large to consider to choose low rotating speed of the chemical pump products or choose air driven products, Containing particle impurities in general chemical pump can not be used to choose corrosion and wear resistance or stainless steel sewage pump, SFB stainless steel centrifugal pump, SFBX stainless steel self-priming pump products.
Two, all kinds of chemical pump
1, IH stainless steel chemical pump model parameters, IHF fluorine plastic chemical pump model parameters of two pump model parameters consistent choice of fluorine plastic chemical pump only need to IH chemical pump model in front of the letter IH into IHF.
2, polypropylene plastic chemical pump has two kinds of self-priming type and non-self-priming type, self-priming type in front of the letter FPZ, non-self-priming type belongs to the centrifugal chemical pump type FP, polypropylene material to transport mild corrosive liquid, specific to which medium can refer to PP to enhance the corrosion resistance of polypropylene chemical pump.
3, non-sealed chemical self-priming pump product material has a variety of materials can adapt to all kinds of chemical liquid, material has a variety of stainless steel, polypropylene, fluorine plastic and so on. It is mainly used for pumping all kinds of medium with low liquid level.
