KNF BLOG Management of Particulate Matter (PM) Exhaust Gas with KNF Pumps Due to the increasing environmental issues and the strengthening of emission regulations, automobile manufacturers are required to find innovative approaches to reduce the environmental impact of vehicles. From 2025 onwards, European emission regulations will target not only exhaust particles but also dust emissions. With the increasing weight of electric vehicles, this mode of transport is also included in the scope of regulations focused on reducing emissions from tires, brakes, and road surface wear. KNF diaphragm pumps can play a crucial role in measurement and control systems developed for this purpose.

There are several options for the electrical connection and control of pumps for operation, each with different technical implications. When engineers, designers, and planners attempt to operate a pump within a system, they inevitably face issues related to power supply and control methods for the pump. Therefore, it is helpful to have an understanding of the common electrical connection and control options.

This is the replacement procedure for the diaphragm and valve of the N84 series.

We propose the KNF vacuum pump, which is optimal for hydrogen recirculation in fuel cell systems, combining technical challenges such as pump airtightness and energy efficiency. With KNF's unique digital customization, it is possible to achieve the ideal design for your system.

The new brushless motor options developed by KNF enable next-generation pump technology with unprecedented advantages. Pumps are all about drive. This insight led KNF to take a significant step forward by fundamentally rethinking the entire drive unit, including the motor, pump housing, and mechanical drive components. The new drive unit is called KNF DC-BI and is equipped with an advanced brushless DC motor developed in-house.

This is the procedure for replacing the diaphragm and valve of the N922 series.

The DC-BI is the first brushless DC motor developed in-house by KNF in its history. This next-generation brushless motor further enhances the advantages of KNF diaphragm pumps, such as performance, robustness, durability, and digital customization features. The new diaphragm pump is very compact due to a new motor mount concept that integrates the motor into the pump housing. The motor is positioned near the ball bearings, and its dimensions have also been optimized. This reduces the load on the pressure and vacuum pump, extending the pump's lifespan. Additionally, we have developed electronics and software equipped with new features that enable full control of the motor. This allows for the individual programming of motor characteristics and control. The pump characteristic curve can be customized and precisely defined to meet exact needs. Extensive parameterization is a key feature of all KNF motors in the "Digital Customization" series.

The explosion-proof gas pumps of the N87 series and N922 series, which have received positive feedback for sampling combustible gases and gas transfer, have passed the explosion-proof structure electrical equipment type certification in Japan. Against the backdrop of initiatives such as the "2050 Carbon Neutral Declaration," applications handling combustible gases, including methanation and hydrogen gas utilization, are increasing daily, and practical demonstration experiments are actively being conducted. KNF offers a wide range of explosion-proof gas pumps certified with IECEX / ATEX that are suitable for combustible gases, including hydrogen gas, and many customers are already using them. In response to the demand for explosion-proof certified products in Japan, we have obtained explosion-proof certification for two models of compact gas pumps.
