Both are Load Sensing (LS) + Pressure Limiting (DR) controls. The key difference is that DFR1 has an internally plugged X port (external control line connection). This makes it simpler for standard applications where remote pressure control via an external pilot line is not needed. The pressure cutoff is adjusted directly on the pump's control cover.
It operates in two stages:
This pump has two case drain ports. You must connect one of them directly to the tank (reservoir) with a dedicated line. The second port must be plugged. The drain line must have zero backpressure (max 0.5 bar) to prevent damage to the shaft seal. Do not connect both drains to different points.
Yes, it is common in mobile machinery. Ensure:
The standard nominal speed for the 140 size is 1500 rpm. While the catalog may list a maximum of 1800-2000 rpm, running at higher speeds requires excellent suction conditions (pressurized inlet > 0.8 bar abs) and may reduce service life. Always consult the performance curves for your specific viscosity.
V stands for FKM (Viton) seals. This is suitable for a wider range of fluids, including certain biodegradable oils (HEES) and high-temperature applications. If you are using standard mineral oil, NBR (code 'P') is also acceptable, but 'V' offers better chemical resistance.
