• Direct Dimensional Match: Replicates the working length and seat dimensions of the OEM seal, allowing for a drop-in replacement without pump modification.
• High-Temp FKM: Standard with high-grade FKM (Viton®) bellows to withstand the elevated temperatures of palm oil processing.
Key Features
• Kewpump Compatible: Precision-engineered replacement for Kewpump chemical process pumps (KS, KCM series) used extensively in palm oil and oleochemical industries.
• Abrasion Resistant: Solid Silicon Carbide faces resist the sand, shell, and dirt often found in crude palm oil and sludge.
• Flexible Drive: The elastomer bellow compensates for the shaft deflection and vibration common in belt-driven Kewpump applications.

Workshop
This workshop is equipped with professional processing equipment and integrated with standardized material warehousing management, enabling a one-stop production process from precision machining to finished product delivery. It ensures part machining accuracy and production efficiency, meeting various high-specification manufacturing requirements.
Product Research, Development and Testing
Our Product R&D and Testing focuses on optimizing seal performance through advanced simulation and material analysis. All seals undergo rigorous trials, including thermal cycling and pressure tests, to ensure durability, minimal leakage, and long service life in demanding industrial environments.
Industry Solutions
Case Study
Palm Oil Sludge Pump: A palm oil mill's sludge pump (Kewpump KS) was eating through carbon seals every 2 weeks. We switched to this SiC Elastomer Bellow seal. The hard faces crushed the sand particles, extending seal life to 6 months.
Testimonials
We rely on Kewpumps for everything. These SiC replacements are half the price of the OEM and last just as long in the sludge pits.
