Danfoss Energy Options has launched the Vickers PVMX axial piston pump, that includes 3,800 rpm operation, 350 bar strain score, and power restoration capabilities. The pump targets servo-hydraulic functions in injection molding and vertical presses with potential power financial savings as much as 80 p.c.
Danfoss Energy Options has launched the Vickers PVMX axial piston pump, concentrating on effectivity enhancements in industrial hydraulic methods by way of greater working speeds and regenerative power restoration. The medium-pressure pump enters the market initially in a 28-cc displacement configuration for functions 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 p.c 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 amenities.
The pump’s two-quadrant operation functionality permits bidirectional movement with out extra valving {hardware}. Movement course reversal happens by way of both servo motor course modifications or the pump’s over-center design, simplifying hydraulic circuit structure whereas supporting movement management features together with actuator retraction, managed deceleration, and strain reduction cycles.
Power restoration performance represents a main design focus. Throughout operations the place actuators reverse course or gravity assists motion, fluid movement routes again by way of the pump, mechanically driving the linked servo motor. The motor operates as a generator on this mode, returning electrical power to the system. This regenerative braking course of reduces warmth technology and principal motor load throughout repetitive work cycles.
Power consumption comparisons with conventional fixed-speed pump methods present potential financial savings as much as 80 p.c, depending on responsibility cycle traits. Contributing elements embrace on-demand operation eliminating idle losses, greater pace operation enabling motor downsizing, power recuperation offsetting enter energy necessities, and diminished cooling system calls for from decrease warmth technology.
“Compact, environment friendly, and good, the PVMX contributes to smaller system footprints, decrease cooling necessities, and diminished put in motor energy,” mentioned Yuanjin (Stein) Wang, World Product Administration Director, Pumps and Motors, Industrial division, Danfoss Energy Options. “This revolutionary pump empowers OEMs and system designers to fulfill future sustainability targets whereas concurrently growing throughput and lowering the whole 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 unique gear producers engaged on new designs or retrofit tasks.
