What are the advantages of fluoroplastic chemical pumps?

　　Fluorine plastic chemical pump overflow part of the material selection is a strong corrosion-resistant fluorine plastic made of fluorine plastic chemical pumps, fluorine plastic chemical pumps can pump any strong corrosive liquid media, fluorine plastic chemical pumps are widely used in pickling, electric power, papermaking, pesticides, plating, chemical, petroleum, metallurgy, pharmaceuticals and other industries in the field. Processes such as waste water and acid can be handled.

　　So what are the advantages of fluoroplastic chemical pumps?

　　1. Pump flange: the standard requires axial open pump casing flange pressure level of 2MPa, cantilever or other radial split pump casing flange pressure level is not less than 4MPa; flange back should be all flat (face) or in the provisions of the part of the countersinking; convex flange and then finishing should be processed a number of serrated vortex grooves or concentric ring grooves.

　　2. Pump support: for horizontal cantilever pumps usually use the centerline support mode, and not recommended to use the foot installation.

　　3. Impeller: The standard requirement is that the impeller should be fully enclosed and is a whole casting, the impeller should be fixed on the shaft with a key.

　　4. Shaft sleeve: the thickness of the small radius of the shaft sleeve should be not less than 2.5mm.

　　5. Wear ring: the standard should be in the ‍‍ fluoroplastic chemical pump ‍‍‍ body and impeller are set up on the replaceable wear ring (mouth ring).

　　6. Seal: The standard specifies that chemical pumps should use mechanical seals, and mechanical seals must be assembled structure.

　　7. Balance: impeller, balance drum and similar major rotating parts must be done G1.0 level dynamic balance; balance with the weight of the mandrel should not exceed the weight of the balanced parts.

　　8. Coupling: the coupling should be used flexible element coupling (i.e., metal diaphragm coupling), must be used to lengthen the coupling, lengthening parts of the nominal length of at least 125mm, the length should make it easy to remove the coupling, bearings, seals and rotor, without having to dismantle the drive machine and suction and discharge piping.

　　Characteristics and selection requirements of fluoroplastic chemical pumps:

　　Typical pumps used in chemical production process are: feed pumps, reflux pumps, tower bottom pumps, circulating pumps, product pumps, injection pumps, make-up pumps, flushing pumps, sewage pumps, fuel oil pumps, lubricant pumps and sealing liquid pumps.
