High Performance 24V BLDC Coolant Pump for Electric Insulating Oil Circulation

OWP-BL43-300 Electric Coolant Pump: A Reliable Solution for Efficient Fluid Circulation

The OWP-BL43-300 Electric Coolant Pump is engineered to deliver exceptional performance and durability, equipped with a suite of advanced features to ensure safe and efficient operation. It boasts constant flow control, reverse polarity protection, and dry running protection, along with safeguards against overvoltage, overcurrent, overload, and overtemperature. As a single-stage centrifugal pump, it adopts a magnetic force transmission (shield pump structure) that eliminates leakage risks, while its high-efficiency brushless DC motor reduces power consumption and extends the service life to over 20,000 hours. Additionally, it supports speed control and operates within a wide temperature range, making it adaptable to diverse harsh environments.

Key Applications: Focus on Electric Insulating Oil Circulation

A primary application of the OWP-BL43-300 pump is in the circulation of electric insulating oil, a critical task in electrical equipment such as transformers, capacitors, and high-voltage switches. Electric insulating oil plays a dual role: it insulates electrical components to prevent short circuits and dissipates heat generated during operation to maintain equipment performance. The pump’s constant flow control ensures a steady supply of insulating oil, guaranteeing uniform heat distribution and consistent insulation performance. Its wide working temperature range (-40℃ to +85℃) allows it to function reliably in both cold outdoor installations and high-temperature indoor environments, while the IP68 rating protects it from dust and water ingress—essential for equipment located in damp or harsh industrial settings. Moreover, the pump’s low noise (≤60dB) and long service life minimize maintenance needs, making it ideal for long-term, continuous operation in electrical systems where downtime is costly.

Competitive Advantages

The OWP-BL43-300 stands out from competitors due to three key strengths. First, its motor efficiency is 3-5% higher, thanks to professional electromagnetic theory design verification that optimizes energy conversion. Second, its hydraulic efficiency is superior: professional software is used for simulation calculations in hydraulic design, ensuring the impeller and volute achieve the best match to maximize fluid flow and lift. Third, it uses automotive-grade electronic components, enabling it to withstand extreme harsh operating conditions—from wide temperature fluctuations to voltage spikes—without compromising performance. These advantages make the pump a cost-effective and reliable choice for demanding fluid circulation tasks.
