The OWP - BL93 - 200 electric coolant pump features a closed - type impeller, which is key to its high efficiency and low - noise operation. In an electric forklift's working environment, minimizing noise is crucial for operator comfort and communication. The permanent magnet brushless design not only results in a compact size but also reduces power consumption, which is beneficial for the overall energy management of the forklift, especially considering the battery - powered nature of the vehicle.

The use of ultra - high - life friction - pair materials in the shaft system ensures long - term durability. The pump can withstand the continuous operation required to cool the electric forklift's battery. The combination of centrifugal and shielding structures enhances the pump's performance and provides protection against potential damage. The lifetime maintenance - free feature is a significant advantage, as it reduces the downtime and cost associated with maintenance. Additionally, the multiple protection functions, such as reverse connection, over - voltage, over - current, dry - running, and over - temperature protection, safeguard the pump and the battery from potential harm.

In the electric forklift battery cooling system, the OWP - BL93 - 200 electric coolant pump plays a vital role. With a rated flow rate of 1800L/H at 8M head and a max flow of 2800L/h, it can effectively circulate the coolant, which can be a mixture of glycol(50 - 60%)+water, dielectric oil, or electronic fluorinated solution.

The wide medium temperature range of - 40 - 85℃ allows the pump to adapt to different working conditions. Whether the forklift is operating in a cold warehouse or a hot outdoor yard, the pump can ensure proper cooling of the battery. The IP68 rating protects the pump from water and dust, which are common in the areas where electric forklifts operate. The low noise control of ≤45dB ensures that the pump does not add excessive noise to the working environment. Its long service life of over 20000 hours and comprehensive protection functions make it a reliable choice for maintaining the optimal temperature of the electric forklift battery. This helps to extend the battery's lifespan and ensure the smooth operation of the electric forklift, as a well - cooled battery can perform more efficiently and consistently.
