Ultra-Compact 35dB Leak-Proof Maintenance-Free BLDC Electric Coolant Pump for Server Rack Liquid Cooling
Product Overview
The OWP-BL43-440C is an ultra-compact, whisper-quiet BLDC electric coolant pump featuring a sealless magnetic drive design that eliminates leakage risk entirely. Operating at just 60dB with zero maintenance requirements, this pump is engineered specifically for server rack liquid cooling, immersion cooling systems, and space-constrained thermal management modules where reliability and silence are paramount.
Key Features
60dB Silent Operation: Optimized impeller hydraulics, precision-balanced rotor, and sealless canned motor construction deliver best-in-class acoustic performance, meeting the strictest noise requirements for data center and office-adjacent server environments.
Leak-Proof Sealless Design: Magnetic drive eliminates traditional mechanical seals — the single most common failure point in coolant pumps. Zero leakage design protects sensitive electronics and ensures system integrity over the entire service life.
Ultra-Compact Footprint: Space-efficient 185x95x120mm form factor fits seamlessly into 1U/2U server rack cooling modules, immersion cooling tanks, and densely packed thermal management assemblies.
Zero Maintenance: Sealed-for-life bearings and contactless magnetic coupling require no lubrication, seal replacement, or periodic servicing — reducing operational costs and eliminating unexpected downtime.
OEM Customization Ready: Available with custom voltage configurations, connector options, mounting brackets, and private labeling to meet specific system integrator requirements.
Applications
Server Rack Liquid Cooling (CDU)
Immersion Cooling Tanks
Edge Computing Thermal Management
HPC Cluster Cooling
Data Center Direct-to-Chip Cooling
Compact Industrial Thermal Modules
Why Choose OWP-BL43-440C
For data center operators and server OEMs, pump failure means server shutdown. The OWP-BL43-440C eliminates this risk with its sealless magnetic drive architecture — no seals to wear out, no leaks to damage equipment. Combined with ultra-silent 60dB operation and a compact form factor, it represents the most reliable cooling solution for mission-critical IT infrastructure.
