A4VTG90HW 32R/32L
A4VTG90 series hydraulic pump's development source ten remaining years of life's whole world applies the experience in the company product in the engineering machinery market, performs in the mature variable ram pump foundation to improve, causes it suitably to apply in the concrete agitation vehicle hydraulic actuation system.
Characteristic:
The profession walks the machinery to use the hydraulic element;
The slanting disk axial plunger variable displacement pump, is suitable in walks machinery's closed return route hydraulic pressure actuation;
Hydraulic pump's current capacity in proportion to pump's rotational speed and displacement;
May through adjust the slanting disk angle to implement the limitless variable;
When slanting disk pivot angle after zero position, the liquid flow commutation is steady;
The high-tension side two overflow valve safeguarding hydraulic element [pump and motor] do not overload
The built-in donkey pump achievement makes up the oil and the check oil pump
Through built-in makes up the oil-overflow valve limit to make up the oil pressure most greatly
The fixed working pressure may achieve 40MPa
Selects the longevity surface high accuracy bearing
Selects the Parker seal:
