Danfoss Energy Options has launched the Vickers PVMX axial piston pump, that includes 3,800 rpm operation, 350 bar strain ranking, and vitality restoration capabilities. The pump targets servo-hydraulic purposes in injection molding and vertical presses with potential vitality financial savings as much as 80 %.
Danfoss Energy Options has launched the Vickers PVMX axial piston pump, focusing on effectivity enhancements in industrial hydraulic techniques by increased working speeds and regenerative vitality restoration. The medium-pressure pump enters the market initially in a 28-cc displacement configuration for purposes together with injection molding, die casting, and vertical press operations.
The PVMX operates at steady strain as much as 350 bar with rated rotational speeds reaching 3,800 rpm, representing a 35 % pace enhance over earlier Vickers medium-pressure pump fashions. The upper pace vary aligns with servo motor traits, enabling sooner machine cycles and supporting the usage of smaller electrical motors in system designs. Acoustic efficiency reaches 72 decibels at 280 bar and three,000 rpm, addressing noise necessities in industrial amenities.
The pump’s two-quadrant operation functionality permits bidirectional movement with out extra valving {hardware}. Circulation path reversal happens by both servo motor path adjustments or the pump’s over-center design, simplifying hydraulic circuit structure whereas supporting movement management capabilities together with actuator retraction, managed deceleration, and strain reduction cycles.
Vitality restoration performance represents a main design focus. Throughout operations the place actuators reverse path or gravity assists motion, fluid movement routes again by the pump, mechanically driving the linked servo motor. The motor operates as a generator on this mode, returning electrical vitality to the system. This regenerative braking course of reduces warmth era and foremost motor load throughout repetitive work cycles.
Vitality consumption comparisons with conventional fixed-speed pump techniques present potential financial savings as much as 80 %, depending on responsibility cycle traits. Contributing components embody on-demand operation eliminating idle losses, increased pace operation enabling motor downsizing, vitality recuperation offsetting enter energy necessities, and decreased cooling system calls for from decrease warmth era.
“Compact, environment friendly, and good, the PVMX contributes to smaller system footprints, decrease cooling necessities, and decreased put in motor energy,” stated Yuanjin (Stein) Wang, World Product Administration Director, Pumps and Motors, Industrial division, Danfoss Energy Options. “This modern pump empowers OEMs and system designers to fulfill future sustainability targets whereas concurrently growing throughput and lowering the overall value of possession.”
The pump meets ISO and SAE interface requirements with management choices together with strain compensation, load sensing, and twin displacement configurations. A number of drive shaft preparations, through-drive configurations, mounting flanges, and port choices present integration flexibility for authentic tools producers engaged on new designs or retrofit tasks.
