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 %.
Danfoss Energy Options has launched the Vickers PVMX axial piston pump, focusing on effectivity enhancements in industrial hydraulic programs via increased 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 % velocity enhance over earlier Vickers medium-pressure pump fashions. The upper velocity vary aligns with servo motor traits, enabling sooner machine cycles and supporting using 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 stream with out extra valving {hardware}. Move path reversal happens via 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 strain aid cycles.
Vitality restoration performance represents a main design focus. Throughout operations the place actuators reverse path or gravity assists motion, fluid stream routes again via 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 major motor load throughout repetitive work cycles.
Vitality consumption comparisons with conventional fixed-speed pump programs present potential financial savings as much as 80 %, depending on responsibility cycle traits. Contributing components embody on-demand operation eliminating idle losses, increased velocity operation enabling motor downsizing, power recuperation offsetting enter energy necessities, and lowered cooling system calls for from decrease warmth technology.
“Compact, environment friendly, and good, the PVMX contributes to smaller system footprints, decrease cooling necessities, and lowered put in motor energy,” mentioned 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 growing throughput and decreasing the full price 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 initiatives.
