Hydraulic Pump Control Solution – Bosch Rexroth RKP-PQ | Amplifier Card Series
Where This Product Is Used
The Bosch Rexroth RKP-PQ Amplifier Card Module is engineered for closed-loop electrohydraulic control systems where precise regulation of pump pressure and flow is critical. Typical deployment environments include:
- Injection Molding Machines – Maintains stable clamping pressure and shot velocity via real-time pump output adjustment.
- Metal Stamping & Press Lines – Delivers consistent hydraulic force profiles to protect tooling and ensure part repeatability.
- Industrial Test Benches – Enables programmable pressure/flow setpoints for fatigue, burst, and endurance testing rigs.
- Marine & Offshore Hydraulics – Provides reliable amplifier control in high-vibration, salt-air environments.
- Steel Mill Rolling Equipment – Regulates roll-gap hydraulics under high-load, continuous-duty cycles.
- Mobile Heavy Equipment – Integrates with variable-displacement piston pumps on excavators and cranes.

Application-Specific FAQ
Q: Is the RKP-PQ compatible with Rexroth A10V / A4V axial piston pumps?
A: No. The RKP-PQ is specifically designed for the RKP radial piston pump series. For A10V/A4V pumps, Rexroth uses the VT-VSPA1 or VT-MSPA1 amplifier card family.
Q: Can I use this card with a Siemens S7 PLC analog output?
A: Yes. Configure the card for 4–20 mA input mode and connect directly to a standard S7-300/400/1500 analog output module (AO ±20 mA range).
Q: What is the lead time for this module?
A: In-stock units ship within 1–2 business days. Out-of-stock sourcing typically takes 5–10 business days depending on origin warehouse.
Q: Do you provide a warranty?
A: Yes — 12-month warranty against manufacturing defects. DOA units are replaced or refunded within 30 days of delivery.
Q: Can Konmask assist with commissioning or parameter setup?
A: We provide the Bosch Rexroth technical datasheet and application notes. For on-site commissioning support, we can refer you to certified Rexroth service partners in your region.
