Duplomatic VPPL hydraulic pumps are available in 7 displacements: VPPL-008, VPPL-016, VPPL-022, VPPL-036, VPPL-046, VPPL-070, VPPL-100, suitable for medium pressure open circuit applications, please consult Poocca hydraulic manufacturer for details.
โ The VPPL is a variable displacement axial piston pump with variable swashplate for open circuit and medium pressure applications.
โ Available in seven nominal sizes with displacements of 8, 16, 22, 36, 46, 70 and 100 cm3/rev.
โ The pump flow is proportional to the speed and the swashplate angle, Duplomatic VPPL piston pumps are continuously adjustable. The maximum and minimum angles can be mechanically limited by suitable adjusting screws.
โ Typically available with SAE J744 2-hole flange and SAE J744 cylindrical with keyed shaft.
โ Duplomatic VPPL hydraulic pumps are available with four different types of modulation control, each depending on the application requirements.

– The VPPL pumps can be installed both in a horizontal and vertical position, with the shaft in an upward position.
Note: the drain port has to be oriented so that the oil level inside the pump body is never lower than 3/4 of its volume.
– In the case of installation above the oil level, check that the minimal inlet pressure is not lower than -0.2 bars (relative). If a low noise emission level is required, the installation inside the tank is suggested.
In case of an installation inside the tank, with an oil level which does not grant complete pump submersion, it is suggested to adjust thee drain tube so that the pump higher bearing can be always lubricated.
– Before starting, the pump body has to be filled with the fluid.
– Check the pump direction of rotation.
– It is necessary to vent the air from the delivery connection before operating it the first time. If the air venting should be difficult, the use of a venting valve is recommended.
The pump start up should occur with the plant at minimum pressure, especially with low temperatures.
– The suction tube has to be suitably sized so that the suction pressure is never lower than -0.2 bar (relative). Bends or restrictions or an excessive tube length could further decrease the value of the suction pressure with a following increase in the noise emissions and a decrease in the pump lifetime.
– The drainage tube has to be sized so that the pressure inside the pump body is always lower than 0.5 bars (relative), even during the dynamic change and flow rate phases. The minimum piping size is 3/8โ for the pump type 008, 016 and 022, while it should be at least 1/2โ for the
pumps type 036 and 046, 3/4โ for the 070 and 100 pumps type.
The drain tube has to unload inside the tank far from the suction area.
– No check valves allowed on the suction line. As for details and the installation of filter elements, see paragraph 2.3.
– The motor-pump connection must be carried out directly with a flexible coupling, to reduce at the minimum the axial and radial loads on the pump shaft. The alignment tolerance between the two shafts must be within 0.05 mm.
