| High Light | Corrosion Resistant Chemical Pump Seal ，High Temperature Mechanical Seal ，Double-face Balanced IHF Seal | ||
The IHF chemical pump is a fluoroplastic-lined centrifugal pump designed for transferring highly corrosive and oxidizing media. The matching mechanical seal must meet three core requirements: chemical corrosion resistance, resistance to medium erosion, and compatibility with the fluoroplastic pump structure. Below is comprehensive technical information about this seal:
Based on the hazard level of the conveyed medium, IHF chemical pumps are equipped with two mainstream seal types:
| Seal Type | Applicable Working Conditions | Structural Features |
|---|---|---|
| Single-face unbalanced mechanical seal | Conventional corrosive media (e.g., dilute sulfuric acid, sodium hydroxide solution), non-toxic, low-volatility media |
1. Simple structure, low cost 2. Torque transmission via multi-spring or single-spring 3. Secondary seal directly fits the fluoroplastic pump shaft sleeve, no risk of shaft sleeve wear 4. No external buffer fluid system required, easy to install and maintain |
| Double-face balanced mechanical seal | Highly toxic, volatile, flammable/explosive media (e.g., concentrated nitric acid, organic solvents) |
1. Double-seal-face design, with buffer/isolation fluid filled in the intermediate cavity 2. Balanced structure reduces seal face specific pressure, extending service life 3. Compatible with API-standard flushing schemes, enabling zero leakage 4. Requires a matching buffer fluid circulation system to enhance safety |
General Structural Advantages
| Parameter Category | Single-face Seal | Double-face Seal |
|---|---|---|
| Applicable Pressure Range | ≤1.0 MPa (10 bar) | ≤1.6 MPa (16 bar) |
| Applicable Temperature Range | -20°C ~ 200°C (depending on secondary seal material) | -40°C ~ 250°C (when paired with metal bellows structure) |
| Applicable Rotational Speed | ≤3000 rpm | ≤3000 rpm |
| Shaft Diameter Compatibility Range | 20 mm ~ 100 mm (covers all IHF100~IHF200 pump models) | 25 mm ~ 120 mm |
| Allowable Shaft Runout | ≤0.05 mm | ≤0.03 mm |
| Leakage Standard | ≤5 drops/min (in clean water conditions) | Zero leakage (when buffer fluid circulation is normal) |
Material selection for IHF pump seals directly determines seal life; it should be tailored to the medium’s corrosiveness, temperature, and solid content:
| Conveyed Medium Type | Seal Face Material Combination | Metal Component Material | Secondary Seal Material | Expected Service Life |
|---|---|---|---|---|
| Dilute acids/alkalis/salt solutions (e.g., 5% sulfuric acid, NaOH) | Silicon Carbide (SiC) / Impregnated Graphite | 316L Stainless Steel | Fluororubber (FKM) | 8000~12000 h |
| Concentrated acids/strong oxidizers (e.g., concentrated nitric acid, hydrogen peroxide) | Silicon Carbide (SiC) / Silicon Carbide (SiC) | Hastelloy C276 | Perfluoroelastomer (FFKM) | 6000~10000 h |
| Organic solvents | Tungsten Carbide (WC) / Silicon Carbide (SiC) | 316L Stainless Steel | Polytetrafluoroethylene (PTFE) | 10000~15000 h |
| Media containing solid particles (e.g., acid/alkali solutions with sediment) | Tungsten Carbide (WC) / Tungsten Carbide (WC) | 316L Stainless Steel + Ceramic Coating | Fluororubber (FKM) | 3000~5000 h |
| Failure Phenomenon | Core Cause | Targeted Solution |
|---|---|---|
| Seal face overheating/smoking |
1. Excessive seal compression 2. No flushing fluid, dry friction on seal face 3. Excessive shaft runout |
1. Adjust compression to the standard range 2. Activate the flushing pipeline and inject clean medium 3. Overhaul the pump shaft and bearings to correct coaxiality |
| Excessive medium leakage |
1. Aged/deformed secondary seal 2. Scratched/worn seal face 3. Spring failure |
1. Replace with new secondary seals 2. Lap or replace the seal face 3. Replace with springs of the same specification |
| Abnormal noise during seal operation |
1. Spring detachment/jamming 2. Loose shaft sleeve 3. Impurities entering the seal chamber |
1. Disassemble the seal and reinstall the spring 2. Tighten the shaft sleeve lock nut 3. Clean the seal chamber and check for flushing pipeline blockages |
