Marzocchi 0.5 D 0,50 External Gear Micropump
The Marzocchi 0.5 D 0,50 is a compact fixed-displacement external gear micropump in the 0.5 group, suitable for small hydraulic circuits and auxiliary power systems. Displacement is 0.5 cm³/rev, with a manufacturer-catalogue flow of 0.75 l/min at 1500 rpm.
This clockwise-rotation micropump supports 190 bar continuous operating pressure (P1), 210 bar intermittent pressure (P2) and 230 bar peak pressure (P3), subject to the manufacturer's operating and speed limits. Maximum speed: 7000 rpm.
The 0.5-series micropump features a compact aluminium body, standard drive-shaft arrangement and G1/4 connection thread. Confirm the exact mounting version and port configuration when selecting a replacement pump.
Operating limits and shaft configuration
The catalogue pressure ratings P1/P2/P3 apply at speeds up to 3000 rpm for this model. P2 is permitted for a maximum of 20 seconds and P3 for a maximum of 2 seconds. The listed maximum pump speed is a separate limit and must not be combined with full pressure without manufacturer confirmation.
The standard shaft has a Ø6 mm drive section, tang and M6 threaded end. The optional G shaft has a different Ø8 mm tang-drive geometry and must be specified separately. Confirm the complete ordering code and mating coupling before ordering. Dimensions M and L refer to the manufacturer's standard-version drawing on catalogue page 12.
The quoted flow is the catalogue value at 1500 rpm; it is not the maximum flow. Actual delivered flow depends on speed, pressure, viscosity and volumetric efficiency.
Applications
Compact hydraulic units, precision auxiliary systems, industrial equipment, OEM installations and MRO replacement of equivalent Marzocchi 0.5-series gear micropumps.
