1. Introduction
Most industrial users only purchase bare pump hosts in the early stage of equipment selection, resulting in a large number of hidden problems in actual production: unfiltered air source causes pneumatic motor jamming and shortened service life; unregulated air pressure leads to unstable flow rate; lack of pulsation damping and back pressure components causes splashing, dripping and inaccurate filling; no pressure relief valve leads to pipe burst and pump body stalling caused by pipeline blockage; no electrostatic grounding accessories lead to potential safety hazards in flammable

9. Common Industry Misconception Correction
1. Misconception 1: A bare pump can meet normal production needs
Correction: A single bare pump is an incomplete semi-finished product, which has unstable speed, no safety protection and short service life, and cannot meet standardized industrial production.
2. Misconception 2: Only explosion-proof workshops need electrostatic grounding accessories
Correction: Fluid friction during the conveying of coatings, adhesives, solvents and oil products will generate static electricity, and grounding protection is required for all flammable liquid working conditions.
3. Misconception 3: High-viscosity pumps do not need pulsation dampeners
Correction: High-viscosity media have larger conveying pulsation and flow fluctuation, and dampeners are more needed to stabilize pressure and flow.
4. Misconception 4: Short pipelines do not need pressure relief valves
Correction: Instant blockage caused by material crusting and impurities will cause pipeline overpressure, and pressure relief protection is required for all liquid circuit systems.
5. Misconception 5: All accessories are universal
Correction: Sanitary, explosion-proof, anti-corrosion and high-viscosity accessories are exclusive and non-universal, and mixed use will cause pollution, corrosion and safety accidents.
