FAQ:
Q1: What is the part number for the main pump of Cat 320D?
A: Common main pump part numbers for Cat 320D include 272-6955 and HPV145 (OEM collaboration model).
Q2: How to store a spare Cat hydraulic pump?
A: Store the pump in a clean, dry, and ventilated area, seal all ports to prevent contamination, and avoid placing heavy objects on it.
Q3: What is the difference between a fixed-displacement and variable-displacement Cat pump?
A: Fixed-displacement pumps deliver a constant flow rate at a given speed, while variable-displacement pumps adjust flow based on system demand, improving energy efficiency.
Q4: What causes a hydraulic pump to lose pressure?
A: Pressure loss is caused by internal pump wear, leaking seals, a faulty relief valve, or air in the hydraulic system.
Q5: Are Cat hydraulic pumps compatible with biodegradable hydraulic oil?
A: Yes, but only if the oil meets Cat’s specifications and is compatible with the pump’s seal materials; consult a dealer for recommendations.
