Frequently Asked Questions
Q1: What is the key difference between DR and DRS control?
Both are pressure controls (constant pressure). The DR control is adjusted mechanically via a screw on the pump cover. The DRS control allows for remote hydraulic adjustment via an external pilot pressure signal connected to port X. This lets you change the pump's pressure setting remotely using a proportional valve or a manual relief valve.
Q2: How do I set up the remote pressure control (DRS)?
Connect an external pressure source (e.g., from a hand pump or a proportional reducing valve) to port X on the pump control cover. The pressure at port X will determine the pump's cutoff pressure. Ensure the control pressure line is clean and free of leaks to avoid erratic pump behavior.
Q3: What are the port connections (VPB22)?
VPB22 indicates SAE flanged ports with metric screws and a 22 series port plate. This pump has three main ports:
  • S (Suction): Connect to reservoir
  • P (Pressure): Connect to system
  • L (Case Drain): One of the two drain ports must be connected directly to the tank with zero backpressure; the other must be plugged
Q4: Can I add a gear pump to the back of this unit?
No. The code U00 indicates a standard shaft with no through-drive capability. The shaft does not protrude from the rear housing to drive an auxiliary pump. If you need a multi-pump configuration, you must select a version with a through-drive code (e.g., K01, K02).
Q5: Why are there two case drain ports?
The pump has two case drain ports for installation flexibility. You must connect only one of them directly to the tank (reservoir). The second port must be plugged. The drain line must have zero backpressure (max 0.5 bar) to prevent damage to the shaft seal.
Q6: What is the recommended operating speed?
The standard nominal speed for the A10VSO 140 size is 1500 - 1800 rpm. While the maximum speed may be listed as 2050-2100 rpm, running at higher speeds requires excellent suction conditions (pressurized inlet) and may reduce service life.
Q7: What does the "V" in the code mean for seals?
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.
