Hartmann PVD24 Variable Displacement Axial Piston Pump
Description
A compact variable displacement piston pump for industrial and mobile hydraulics
The Hartmann PVD24 is the largest displacement in the Hartmann Controls PVD 8-24 family: a variable displacement, axial piston, swash plate pump delivering 24 cm3 per revolution. Hartmann describes the PVD series as aimed at both industrial and mobile applications, with continuous operating pressures from 200 to 4500 psi and shaft speeds up to 3200 rpm at atmospheric inlet conditions. The pump is housed in a rugged ductile iron frame and mounts on a standard SAE A 2-bolt flange.
Because displacement is variable, the pump can be paired with a variety of control options, and it carries adjustable minimum and maximum volume stops. It is fitted with a Viton shaft seal and O-rings.

Inlet conditions and what to confirm before ordering
The brochure includes suction characteristics for the PVD 10, 16, 20 and 24, measured with ISO 32 oil at 85 degF and normalised to 1800 rpm. For the PVD24 the chart marks the higher speed range as requiring a flooded inlet, so the reservoir layout and suction line matter. Before ordering, confirm the control option, the porting configuration (side, tandem or rear ports are shown in the dimension drawings), the drive shaft type and the rotation and pressure duty with your hydraulic designer. The PVD47 is shown on the Hartmann site as coming soon. For a larger frame, see the Hartmann PVX 116 pump; more units are listed under pumps.
Documents and quotation

About brand
Hartmann Controls builds hydraulic pumps in Hartland, USA, with axial piston pumps as its core product, plus hydraulic motors and controls. Seven Star LLC, an independent supplier in Oman, lists Hartmann pumps from the PV, PVX, PVC and PVD series, among them the PV320R-AV1-A1D/32002-40 high-pressure axial piston hydraulic pump, and sources Hartmann pumps and replacement units by the model code on the nameplate.
Hartmann pump series
The manufacturer lists its piston pumps in the PV, PVX, PVC, PVD and PVM series, alongside gear pumps. One listed pump carries a PV320 designation. On a variable displacement axial piston pump the swashplate angle sets the output, and the control fitted to the pump decides how it reacts to pressure and flow demand. The manufacturer names industrial, marine, construction and agricultural machinery as its fields, which matches where these pumps turn up in the GCC: deck machinery, mobile equipment and hydraulic power units.
Ordering Hartmann pumps: what we need
Send the full model code and serial number from the pump nameplate. Every block of the code counts: series and displacement, rotation direction, control type, shaft, mounting flange and ports. If the plate is unreadable, give the machine make and model, drive speed, required flow and pressure, shaft and flange dimensions, and photos of the pump from all sides.
