Features of Rexroth variable piston pump A4VS axial piston pump and order codes
Thread Content
Series: A4VSG series axial piston variable pumps. Specifications: 40, 71, 125, 180, 250, 355, 500. Series 1 and 2. Operating pressure: 350 bar; peak pressure: 400 bar. Control methods: Pressure control (DR), Flow control (FR), Hyperbolic power control (LR), Manual control (MA), Electric motor control (EM), Pressure-dependent hydraulic control (EM), Flow-dependent hydraulic control (HM), Hydraulic control with servo/proportional valve (HS), Electronic control (EO), Pressure-dependent hydraulic control (HD), Speed control with secondary control (DS). Features: Axial piston variable pump with swashplate design, specifically engineered for efficient hydraulic drive in open-loop systems. ◆ With swashplate angle indicator ； ◆ Excellent inhalation properties ； ◆ Control response is sensitive ； ◆ Specially designed, long-lasting, high-precision aviation-grade full-roller bearings ； ◆ Low noise, long lifespan, excellent power-to-weight ratio ； ◆ Shaft-through design, capable of being stacked to form a combined pump ； ◆ The flow rate of a hydraulic pump is proportional to the pump’s speed and displacement; adjusting the tilt angle of the swash plate allows for stepless adjustment of the displacement ； ◆ The variable types are comprehensive; the commonly used ones include DR/DRG constant voltage control, LR hyperbolic constant power automatic control, and EO2 electrical proportional control ； ◆ Applicable media: mineral oil, water-ethylene glycol; cleanliness requirement: NAS9 level ； Installation notes: Optional installation locations. The pump casing must be adjusted and operated to remain filled with liquid throughout the process. To achieve the lowest noise level, all connections (intake, pressure, oil drain) must be connected to the tank using flexible connectors. Avoid placing the check valve on the oil drain pipe. This may be permitted in individual cases, but only after consulting with us. Learn more about Rexroth variable piston pumps: http://www.aotuoshi.com/
Project solicitation for the Beijing High-Tech Industry Fund is underway: This fund, initiated by the Beijing Municipal Finance Bureau and the Beijing Municipal Commission of Economy and Information Technology, aims to mobilize private capital to foster the development of high-tech industries. At present, the **Emerging Industries Public Service Platform is responsible for soliciting projects; these projects mainly involve enterprises in areas such as energy conservation, environmental protection, and circular economy, and the fund is intended to provide support to such enterprises. The goal is to help enterprises grow stronger and larger; therefore, the fund generally enters through equity investments and exits after 2–3 years. And it also helps to draw in financial funds from banks and other institutions. If your company falls within the areas supported by the fund, please contact us promptly to register.
