Various pump drives and precision control: Brushless/stepping for pumps.
Achieving miniaturization and high efficiency of pumps. We offer the most suitable motors for flow control at an overwhelmingly low cost, starting from small-lot prototypes.
Pumps" that transport liquids and gases are the heart of various industries, including water treatment, chemicals, healthcare, and food. Depending on the application, there are diverse types such as "metering pumps (like diaphragm pumps)" that deliver a precise amount, and "centrifugal pumps" and "gear pumps" that excel in continuous liquid delivery. In recent years, the drive sources for these pumps have rapidly shifted from traditional constant-speed AC motors to "brushless motors" and "stepper motors," which allow for fine flow adjustments, energy savings, and miniaturization. While we are not a pump manufacturer, we serve as a dedicated contact point for these "motors that are the heart of pumps." We offer an optimal range of motors directly linked to precise flow control and miniaturization of equipment, achieving a balance between the overwhelming price competitiveness of overseas ODMs and Japanese quality through thorough inspection of all domestic products. We strongly support pump manufacturers in their new developments or replacements, whether they want to "develop a new pump unit" or "reassess existing pump motors.
basic information
■Types of Pumps and Required Motor Characteristics - Metering Pumps (Diaphragm Type, Syringe Type): Require precise control of rotation angle and speed. "Stepper Motors," which excel in positioning, are optimal. - Continuous Delivery Pumps (Centrifugal, Screw Type, etc.): Require long lifespan, energy efficiency, and rotational speed control. "Brushless Motors," which are highly efficient, are optimal. ■Benefits of Using Crew-Made Motors - Precise Flow Control: Allows for fine variable adjustments of discharge volume when combined with dedicated drivers. - Space Saving: Contributes to the compactness and lightweight design of the entire pump unit due to high output and small design. ■Main Compatible Products - Brushless Motors: Available in built-in driver type and standard type. Ideal for pumps with continuous operation. - Stepper Motors: Demonstrate power in precise discharge volume control through fine positioning. - Quality Assurance: Conducts domestic inspection of all units from prototype to mass production.
Price information
By utilizing our unique global procurement network (world-standard ODM products), we significantly reduce the development and introduction costs of pumps. Even with small-scale production in the tens of units, we offer price advantages equivalent to mass production, minimizing initial investment and inventory risks for companies.
