وصف تفصيلي
This is a variable pump built with an axial piston rotary group adopting swashplate design, tailor-made for hydrostatic drive systems in open circuit hydraulic applications. The pump’s output flow is strictly proportional to the input drive speed and its own displacement capacity. By precisely adjusting the swashplate inclination angle, the flow rate can achieve stepless infinite variation, which flexibly adapts to different flow regulation requirements of hydraulic systems. It is equipped with high-performance stable bearings, effectively reducing mechanical wear and friction loss, and greatly extending the overall service life of the pump unit. The product supports high permissible drive speed, delivering efficient and powerful hydraulic output under high-speed operating conditions. Meanwhile, it features a favorable power-to-weight ratio and compact overall dimensions, saving installation space, lowering equipment overall weight, and offering outstanding adaptability for both mobile machinery and industrial fixed hydraulic equipment layouts.

Determining the operating characteristics

| Torque | M=(Vg ∙ Δp) /(20 ∙ π ∙ ηhm) | لا شيء جديد |
| Power | P=(2π ∙ M ∙ n)/60000=(qv ∙ Δp)/(600 ∙ ηt) | كيلوواط |
Key
Vg Displacement per revolution in [cm3]
Δp Differential pressure [bar]
n Rotational speed [rpm]
ηv Volumetric efficiency
ηhm Hydraulic-mechanical efficiency
ηt Total efficiency (ηt= ηv*ηhm)
1) The values are applicable:
- At an abs. pressure pabs = 1 bar at the suction port S
- for the optimum viscosity range from Vopt = 36 to 16 mm2/s
- with hydraulic fluid on the basis of mineral oils
2)See diagram on page 9 at speed increase up to nmax adm.
3)The data are valid for values between the minimum required and maximum permissible rotational speed. It applies for external stimuli (e.g. diesel engine 2 to 8 times rotary frequency, cardan shaft twice the rotary frequency). The limit value is only valid fora single pump. The load capacity of the connection parts must be considered.
