---

### **Cons**

1. **Age of the Design (Legacy Technology)**

- The **DG4V series** is not a new model; it follows older hydraulic pump architectures (e.g., gerotor swashplate) that may lack some modern optimizations.

- Newer competitors (e.g., **Bosch Rexroth, Parker Hannifin, or Sunhydraulics**) offer pumps with **higher efficiency, digital integration, and lower emissions**, which may be preferable for cutting-edge applications.

2. **Higher Initial Cost Compared to Simpler Pumps**
