Frequently Asked Questions
Basic Parameters & Selection
What is the displacement of this pump?
The geometric displacement is 22.5 cm³/rev.
What is the maximum working pressure?
The maximum continuous working pressure is 180 bar, the maximum intermittent pressure is 210 bar, and the peak pressure is 230 bar.
What is the rotation direction of the pump?
Clockwise rotation when viewed from the shaft end.
What is the type of the pump's mounting flange interface?
It uses an SAE 2-bolt flange with a square flange port (ISO 8434-1).
Installation & Commissioning
What are the requirements for the drive shaft during installation?
The motor drive shaft and the pump's tapered shaft must be connected via a flexible coupling. The radial runout should be less than 0.1 mm, and the angular error should be less than 1 degree. Rigid connections are strictly prohibited.
What are the requirements for the inlet port?
The inlet line should be as short, straight, and low-resistance as possible. The absolute pressure at the pump inlet during operation must not fall below 0.7 bar. A flooded suction or a boost pump is recommended.
What should be checked before the first start-up?
The pump housing must be filled with clean hydraulic oil. Dry running is strictly forbidden.
How should the case drain port be connected?
The case drain line must be connected directly, without restriction, and without a filter, back to the reservoir. The connection point should be below the fluid level but above the pump centerline. The backpressure in the drain line must not exceed 1 bar.
Operation & Troubleshooting
The pump is very noisy. What is the cause?
The most common causes are cavitation (accompanied by temperature rise) or aeration.
  • Cavitation: Restricted inlet flow. Check for clogged inlet filters, oil viscosity that is too high, or a low oil level.
  • Aeration: Air is being drawn into the suction line due to leaks. You can test this by submerging the suction hose in a bucket of oil.
  • Mechanical Noise: Check for misalignment or damaged bearings.
The calculated flow and the actual measured flow do not match. Is this normal?
Yes, this is normal. Actual Flow = Theoretical Flow × Volumetric Efficiency. The theoretical flow is `22.5 × Speed (rpm) / 1000`(L/min). Volumetric efficiency is typically 90%-95%. An efficiency below 85% indicates pump wear.
The pump is leaking at the shaft seal. How should I handle it?
First, check if the case drain line is blocked. If it is clear, the shaft seal is likely worn and needs to be replaced. Continuing operation with a leaking seal can allow contamination to enter and damage the bearings.
The pressure does not reach the rated value, and the flow is also low. What is the reason?
Possible causes, in order of likelihood:
  1. Internal Pump Wear: Long-term use has increased the clearance between the gear set and side plates, leading to high internal leakage.
  2. System Leakage: Check other valves and actuators in the system.
  3. Low Motor Speed.
  4. Oil Viscosity is too low.
Maintenance
What type of oil is recommended?
The use of ISO VG 32/46/68 mineral-based hydraulic oils (HL, HLP) is recommended. HFC, HFD, HETG, and HEES fluids are also permissible, but seal material compatibility must be verified.
What is the required oil cleanliness level?
A cleanliness level of NAS Class 9 or cleaner is mandatory, equivalent to 18/16/13 per ISO 4406. This is critical for ensuring pump life.
Can I disassemble and repair the pump myself?
It is not recommended. While seal replacement is possible, the installation of the sliding bearings and pressure-compensated side plates requires special tools and pressure testing. For critical applications, the use of an original factory exchange cartridge or complete pump is advised.
What is the expected service life of the pump?
Under correct operating conditions (proper oil cleanliness, appropriate viscosity, rated loads), the B10 life can reach several thousand hours. Oil contamination is the primary cause of reduced lifespan.
