- Displacement range from 2.4 to 9.5 cubic inches per revolution
- Bi-rotational options available
These specs make the P330 suitable for a wide range of applications including agriculture, construction, and material handling equipment.
Comparing Gear Pump Types: P330 vs. Others
To better understand the P330 gear pump’s place in the market, let’s compare it with other common models: P315, P350, and aluminum gear pumps.
P330 vs. P315 Gear Pump
The P315 is often used in medium-duty applications, while the P330 is designed for heavier-duty use.
| Feature | P315 Gear Pump | P330 Gear Pump |
|---|---|---|
| Housing Material | Cast Iron | Cast Iron |
| Max Operating Pressure | ~2500 PSI | Up to 3000 PSI |
| Flow Rate Range | Medium | Medium to High |
| Durability | Good | Superior |
| Best Use Case | General industrial use | Heavy-duty mobile machines |
Verdict: If your application demands higher pressure and longer life, the P330 gear pump is a better investment.
P330 vs. P350 Gear Pump
The P350 and P330 are both Parker cast iron gear pumps, but they serve slightly different purposes.
| Feature | P350 Gear Pump | P330 Gear Pump |
|---|---|---|
| Displacement Options | Smaller range | Wider displacement range |
| Mounting Configurations | Limited | Flexible |
| Weight | Slightly lighter | Heavier due to robust build |
| Application Fit | Light to medium duty | Medium to heavy duty |
Verdict: The P330 gear pump provides more flexibility and higher output, making it better for more demanding environments.
P330 vs. Aluminum Gear Pumps
Aluminum gear pumps are common for light-duty applications and cost-conscious projects. However, there are trade-offs.
| Feature | Aluminum Gear Pumps | P330 Gear Pump |
|---|---|---|
| Housing Material | Aluminum | Cast Iron |
| Max Pressure | ~2000 PSI | Up to 3000 PSI |
| Cost | Lower | Higher but worth it |
| Durability | Moderate | High |
| Use Case | Low-demand equipment | Heavy machinery |
Verdict: For reliability under tough conditions, the P330 is far superior.
Why Choose the P330 Gear Pump?
Still on the fence? Here’s a quick breakdown of why the P330 gear pump often comes out on top:
- Built for rugged environments
- Higher flow and pressure ratings
- More configuration options
