Diaphragm pumps with brushless DC motors
Jun 03, 2010
Diaphragm pumps with brushless DC motorsThe diaphragm pumps equipped with brushless DC (BLDC) motors offer advanced OEM control solutions for handling air, gases, or liquids. Their integrated “feature-packed” controls deliver precise pump performance in direct response to system requirements. The BLDC motors in KNF pumps are designed and manufactured exclusively by KNF to handle the high stresses associated with the reciprocating forces of a positive displacement pump and are consistent with the highest standards of engineering, reliability, and quality.
Compared with conventional DC models, pumps with BLDC motors exhibit low current draw, extended lifetime, and reduced EMI/RFI, while dramatically decreasing pump size, weight, and heat generation. Combining integrated on/off and speed logic signals with feedback and current-limit controls enables users to realize ideal performance and precision that can instantly be varied for OEM system demands. The pumps incorporate an exclusive structured diaphragm promoting high efficiency and flow and allowing the pumped medium to remain pure and contaminant-free. Depending on model, end vacuums up to 29.86 in. Hg (< 0.5 mbar) are achieved using only two stages to yield reduced cost, size, weight, and power requirements.
