Dongguan Haimi is a professional miniature DC pump manufacturer with more than 10 years of R&D and batch production experience, specializing in customized cooling circulation pumps for CNC machine tools, laser processing equipment, industrial small chillers and automated industrial supporting equipment, supplying stable fluid circulation solutions for machinery manufacturers worldwide.
CNC machine cutting fluid circulation and laser equipment constant-temperature cooling are the core application scenarios of our industrial pump products. During long-time uninterrupted processing, machine tools generate massive heat, requiring cooling pumps to run continuously stably against fluctuating liquid temperature and weak alkaline cutting fluid ranging from PH5 to PH10. Our flagship HM6002-1 three-phase pump, a classic DC water pump, covers working voltage from 12VDC to 48VDC, rated power 12~80W, flow 10~30L/min and maximum resistant medium temperature up to 75℃, fully meeting long-term circulating cooling demand of cutting liquid and laser cooling water.
Built-in complete protective functions including dry-run protection, overvoltage, overcurrent and locked-rotor protection, optional 0-5V analog speed regulation and PWM speed control with FG signal feedback, the pump can adjust flow flexibly according to equipment cooling load changes; continuous working lifespan exceeds 20000 hours under standard industrial environment, effectively reducing unexpected shutdown and later maintenance cost of automated production lines. The IP68 waterproof structure and arbitrarily adjustable outlet angle simplify internal pipeline layout inside compact machine equipment.
For small industrial wastewater collection and auxiliary aeration of workshop processing tanks, customers can select our supporting diaphragm pump, which works with main cooling pumps to complete dual functions of cooling circulation and waste liquid transfer inside one machine unit. When outdoor unmanned industrial small equipment needs off-grid cooling circulation without commercial power, our solar DC water pump becomes the preferred matched pumping unit powered by photovoltaic modules.
