Danfoss Energy Options has launched the Vickers PVMX axial piston pump, that includes 3,800 rpm operation, 350 bar stress score, 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 means of 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 stress as much as 350 bar with rated rotational speeds reaching 3,800 rpm, representing a 35 % pace improve over earlier Vickers medium-pressure pump fashions. The upper pace vary aligns with servo motor traits, enabling quicker 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 services.
The pump’s two-quadrant operation functionality permits bidirectional circulate with out extra valving {hardware}. Movement path reversal happens by means of both servo motor path modifications or the pump’s over-center design, simplifying hydraulic circuit structure whereas supporting movement management capabilities together with actuator retraction, managed deceleration, and stress reduction cycles.
Power restoration performance represents a major design focus. Throughout operations the place actuators reverse path or gravity assists motion, fluid circulate routes again by means of the pump, mechanically driving the related servo motor. The motor operates as a generator on this mode, returning electrical vitality to the system. This regenerative braking course of reduces warmth technology and important motor load throughout repetitive work cycles.
Power consumption comparisons with conventional fixed-speed pump techniques present potential financial savings as much as 80 %, depending on obligation cycle traits. Contributing elements embrace 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 technology.
“Compact, environment friendly, and sensible, the PVMX contributes to smaller system footprints, decrease cooling necessities, and decreased put in motor energy,” stated Yuanjin (Stein) Wang, International Product Administration Director, Pumps and Motors, Industrial division, Danfoss Energy Options. “This progressive pump empowers OEMs and system designers to fulfill future sustainability targets whereas concurrently rising throughput and decreasing the full price of possession.”
The pump meets ISO and SAE interface requirements with management choices together with stress 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 unique gear producers engaged on new designs or retrofit initiatives.
