Isopropanol Magnetic Drive Pumps (Anhydrous/Particle-Free)

 

I. Application Industries

Fine Chemicals, Pharmaceutical Chemicals

Isopropanol is used as a solvent/extractant for reactor circulation, intermediate transport, solvent recovery, and tank farm transfer.

 

Electronics & Semiconductors, PCB

Wafer/chip cleaning, photoresist diluent transport, anhydrous isopropanol precision cleaning circulation.

 

Paints & Inks, Daily Chemicals

Paint diluent, ink solvent, perfume/cosmetic raw material transport, fragrance extraction circulation.

 

New Energy, Lithium Batteries

Electrode cleaning, electrolyte auxiliary material transport, electrode degreasing process circulation.

 

Environmental Protection, Hazardous Waste Treatment

Closed-loop transport of isopropanol waste liquid, waste gas scrubbing tower circulation, organic solvent recovery systems.

 

Laboratories, Research Institutes

Experimental solvent circulation, vacuum distillation, precision feeding, small-flow constant-temperature transport.

 

II. Functions of Magnetic Drive Pumps

* Zero Leakage, Anti-Volatilization and Explosion-Proof: Isopropanol is volatile, flammable, explosive, and toxic. Magnetic drive pumps have no mechanical shaft seals and are fully sealed, eliminating leakage and volatilization, thus avoiding the risks of fire, explosion, and personnel poisoning.

* Swelling Resistance, No Media Contamination: Isopropanol swells in common rubber/plastics; magnetic drive pumps use swelling-resistant materials, preventing metal ion precipitation and ensuring high-purity isopropanol.

* Low Shear, No Foaming: Magnetic coupling eliminates mechanical friction, resulting in smooth, low-pulsation delivery without disrupting the isopropanol solvent ratio, suitable for precision processes.

* Explosion-Proof Safety, No Sparks: Isopropanol vapor is explosive upon contact with a spark; magnetic drive pumps eliminate mechanical friction and sparks, making them suitable for Ex d Ⅱ BT4 explosion-proof areas.

* Maintenance-Free, Long-Term Operation: With no easily damaged sealing parts, frequent mechanical seal replacement is unnecessary, supporting 24-hour continuous operation and reducing maintenance costs. Adaptable to automated control and precise conveying. When paired with a frequency converter control cabinet, it achieves constant current/constant pressure, level interlocking, and dry-run protection, and can be integrated into a PLC-based automated production line.

 

III. Isopropanol Magnetic Drive Pump Selection (Key Points)

 

1. Confirm Operating Parameters

 

Medium: Anhydrous isopropanol (particle-free)

 

Temperature: Room temperature (≤60℃, isopropanol boiling point 82.4℃)

 

Concentration: Industrial grade / Electronic grade (high purity)

 

Flow rate: m³/h; Head: m (including pipeline resistance)

 

Environment: Explosion-proof area / Non-explosion-proof area

 

2. Pump Type Selection

 

High-flow circulation / Transfer: Magnetic centrifugal pump

 

Small-flow precise feeding / Proportioning: Magnetic gear metering pump

 

3. Wetted Flow Material (Crucial)

 

Electronic grade / High-purity isopropanol: 316L stainless steel (electrolytic polishing)

 

Industrial grade, swelling resistant: PVDF (polyvinylidene fluoride)

 

Strictly prohibited: Ordinary rubber, PVC, cast iron (swelling / corrosion)

 

Bearings: Silicon carbide (SiC) / ceramic, wear-resistant, swelling resistant, anti-seize.

 

4. Flow Rate and Head Margin: Isopropanol has a slightly higher viscosity than water and is easily vaporized; select a flow rate +15% and a head +20% to prevent gas binding and insufficient flow.

 

5. Motor and Explosion-Proof Rating: Chemical/Electronic Explosion-Proof Areas: Ex d Ⅱ BT4 explosion-proof motor (essential)

Non-Explosion-Proof Laboratories: Corrosion-resistant ordinary motor

Protection Rating: IP55+, moisture-proof and solvent-resistant.

 

6. Control System Selection: Basic Model: Explosion-proof direct-start cabinet (with overload/phase loss protection)

Recommended Model: Variable frequency explosion-proof control cabinet (soft start, constant current, anti-dry running, level interlock, 4-20mA communication).

 

7. Piping Equipment: Piping: 316L stainless steel, PPH, PVDF (resistant to isopropanol swelling)

Inlet: 100-mesh filter (for trace impurities)

Outlet: Check valve, safety valve; high-risk areas should be equipped with a combustible gas alarm interlocked with the pump.
