Pumpenregelsystem SYDFEE-2X/028R-PRA12KD3-0000-A0A1VX2-006 - Bosch Rexroth R900751704

An extra motor costs floor space, cable and starting current. The pump control system SYDFEE-2X/028R-PRA12KD3-0000-A0A1VX2-006 avoids it, because its through-drive carries a second pump while its own variable unit of 28 cm³ controls up to 84 l/min at 280 bar.

Benefits

• Through-drive included, so a further pump runs without a drive of its own.
• 84 l/min at 280 bar from a variable unit of size 28 cm³ with clockwise rotation.
• Geared shaft (R) at the ISO 2-hole flange for the coupling to the motor.
• Swivel angle and pressure control through on-board electronics with an analog command value, preload valve at 250 bar.
• 24 VDC and a 12-pole connector (11 + PE) to EN 175201-804, with FKM seals for hydraulic fluid HLP.
• 25.3 kg weight, which keeps the mounting on compact power unit plates manageable.

Applications

The combination of 28 cm³ and a through-drive fits power units that need one controlled main circuit and one simple secondary circuit, for example tool clamping next to the main axis. The unit also works as a slave inside a group of pumps. Controlled swivel angle keeps losses low when the secondary circuit draws oil only now and then.
