Product Description

This is the Leister AP2D36 variable piston hydraulic pump. Its model is AP2D36LV3RS6-909-4. The Hitachi component number is 4437197. It is the main pump assembly for the Hitachi ZX70-6 excavator and is also compatible with models such as ZX70, ZX70-5A, and ZX70-5G.

1. The pump body is made of high-strength cast iron and is cast as a single piece. The main pump and the pilot pump are integrated. The structure is compact and stable. An original power regulator is equipped, ensuring a linear and smooth flow output, quick action response, and smooth coordination and smoothness of compound actions such as digging, rotating, and lifting. The power is sufficient and the fuel consumption is excellent.

2. The internal piston and the flow distributor have undergone precise quenching and grinding, resulting in strong sealing performance, high pressure resistance, and wear resistance. Long-term earthwork and crushing operations are less likely to encounter internal leakage, pressure drop, or insufficient action.

3. The oil ports, installation holes, spline shafts are fully matched with the original vehicle. No need to modify the pipelines. The entire machine can be directly installed and replaced, making it the preferred accessory for replacing pumps in 7-ton small excavators undergoing major repairs.
