✅ [1] What is GapMaster Non-Galling Metal?
GapMaster Non-Galling Metal Technology Overview
K-PACK’s advanced filling systems incorporate GapMaster non-galling metal components —
the first of their kind developed in Korea.
The Gap-Free / Worry-Free solution significantly enhances the quality, hygiene,
and reliability of filling systems.
Key Features and Differentiation
- - Non-Galling (Gap-Free) structural design
- → Minimizes metal-to-metal friction and prevents wear
- - Enhanced hygiene
- → Prevents residue build-up, fully compatible with CIP (Clean-In-Place) and SIP (Sterilize-In-Place)
- systems
- - Superior durability
- → Extended component life and fewer maintenance cycles
- - Stable precision→ Maintains consistent accuracy even under high-pressure and high-viscosity conditions
✅ [2] How is GapMaster Made?
(Casting & Machining Process)
🏗️ GapMaster Production Process Overview
GapMaster is Korea’s first non-galling metal component
developed specifically for filling machine systems.
It is manufactured through three key steps:
Precision Casting → Heat Treatment → Ultra-Fine Machining
🔧 Main Manufacturing Steps
🥇 1. Precision Casting
- Uses robust casting molds optimized for Gap-Free design
- Ensures uniform metal microstructure for high-pressure resistance
🔥 2. Heat Treatment
Improves surface hardness and wear resistance
by forming customized carbide microstructures,
specifically designed to prevent metal-to-metal adhesion and
avoid Cr23C6-related corrosion issues seen in conventional stainless steels.

⚙️ 3. Ultra-Precision CNC Machining
- Controls critical clearance within 0.01 mm
- Enables non-contact rotational motion
- Prevents leakage without sealing parts
🧩 Summary Line (For emphasis)
From casting to precision finishing,
GapMaster delivers Gap-Free / Worry-Free performance.
✅ [3] Why is it Better?
(Key Advantages of GapMaster Non-Galling Metal)
🌟 Why GapMaster? — The Key Advantages
K-PACK’s GapMaster technology outperforms conventional stainless steel in critical areas of
performance, hygiene, and durability.
Our non-galling metal technology ensures that your filling system runs smoothly, cleanly, and without costly breakdowns.
✅ Core Advantages
🔒 1. Non-Galling Performance
- Prevents galling, seizing, and sticking
- Ideal for metal-to-metal motion in piston, valve, and rotary parts
- Keeps equipment running even under extreme conditions
🧼 2. Superior Hygiene
- No internal friction = no residue build-up
- Prevents micro-scratches that trap bacteria
- Fully supports CIP (Clean-In-Place) and SIP (Sterilize-In-Place)
⚙️ 3. High Durability
- Resistant to wear, pressure, and corrosion
- Longer component life than standard SUS304/316
- Reduces frequency of maintenance
🎯 4. Precision Stability
- Maintains clearance tolerances within 0.01 mm
- Ensures consistent filling accuracy over time
- No need for frequent re-calibration
🧩 Final Summary Line
GapMaster solves the hidden problems of stainless stee
— no seizing, no sticking, no downtime.
✅ [4] Comparison: CPP vs. Lobe Pump
(Circumferential Piston Pump vs. Rotary Lobe Pump)
⚖️ What's the Difference?
While both pumps are widely used in food and cosmetic liquid filling systems,
they differ significantly in terms of precision, hygiene, and material compatibility.
🔍 Key Comparison Table
Feature CPP (Circumferential Piston Pump) Lobe Pump (Rotary Lobe Pump)
| Filling Accuracy | ★★★★★ High (0.5% or less) | ★★ Moderate (~2% deviation) |
| Viscous Product Handling | Excellent for high-viscosity, high- solid products | Tends to slip and pulse with very thick materials |
| Metal Galling Risk | ❌ None – GapMaster non-galling metal | ⚠️ Possible with stainless-to-stainless contact |
| Hygienic Design | Fully CIP/SIP compatible, minimal residue buildup | Requires more effort to clean internal gaps |
| Durability | High wear-resistance, long component life | Moderate — frequent replacement in tough duty |
| Internal Sealing | Gap-Free – no contact or seal wear | Seals may wear and leak over time |
| Application Fit | Ideal for sauces, pastes, honey, jams, condiments | Better for light liquids (milk, oil, water) |
✅ Summary Bullet Points
- - CPP excels in accuracy, durability, and viscous fluid handling
- - GapMaster metal in CPP ensures non-galling, long-life operation
- - Lobe pumps are general-purpose but limited for demanding materials
🧩 One-Line Summary
If your product is thick, sticky, or expensive —
CPP with GapMaster is the smarter, cleaner choice.
