SCHAAF air-hydraulic pump HDL 1000-2500 is a high pressure hydraulic pump. It has 2500 bar, 1600 bar, 1000 bar three maximum pressure options, air pressure side safety valve can be adjusted in the range of 0 to 2500 bar. The booster has a boost ratio of 1:425 bar (bar). The pump is equipped with an aluminum oil tank with a usable capacity of 6 liters, 11 liters or 15 liters. The oil tank has an observable oil level gauge. The pump also features a compressed air regulator and an oil mist, which is used to lubricate compressed air.
The SCHAAF HDL 1000-2500 hydraulic pump is designed for ultra‑high‑pressure applications. It features a selectable maximum pressure of up to 2500 bar, with preset safety limits at 1600 bar and 1000 bar, and an external pressure limiter that can be adjusted between 0 and 2500 bar. The pump includes an air‑driven pressure regulator, oil mist lubricator, and a range of pressure connectors and gauges.
The unit is built on an aluminum oil tank available in 6 L, 11 L or 15 L capacities, a steel‑tube structure with a silencer on the pneumatic side, and is mounted on a mobile base with industrial‑grade casters. Physical dimensions are 640 mm (L) × 352 mm (W) × 340 mm (H) and the weight is approximately 33 kg when filled with oil. Hydraulic oil type is HLP ISO VG 15, and the standard pressure gauge is an O‑100, class 1.0. This manual is written in Chinese.
