Key factors for selecting chemical pumps

Improper selection can lead to low pump efficiency, shortened lifespan, and even safety accidents. The following factors need to be considered:

1. Characteristics of the medium

Corrosivity: Choose corrosion-resistant materials (such as stainless steel 316L, fluoroplastic lining, Hastelloy).

Viscosity: For high viscosity media, screw pumps or gear pumps should be used.

Solid content: For media containing particles, wear-resistant materials or mortar pumps should be selected.

2. Flow rate and head

Flow rate (Q): The volume of liquid transported per unit time (m ³/h).

Head (H): The pump can lift the height of the liquid (m), taking into account pipeline resistance.

3.Temperature and pressure

High temperature media should use high-temperature resistant seals (such as graphite or metal bellows seals).

Multi stage centrifugal pumps or plunger pumps are selected for high-pressure conditions.

4.Sealing method

Mechanical seal: Suitable for most chemical media, the sealing material needs to be selected according to the medium.

Magnetic seal: No leakage, suitable for high-risk media.

Packing seal: Low cost, but prone to leakage, gradually phased out.

4.material selection

Stainless steel 304/316: resistant to general corrosion.

Fluorine lined plastic (PTFE): resistant to strong acids and alkalis.

Ceramic/Silicon Carbide: Wear resistant and corrosion-resistant.
