Description
Product Overview: PIONEER PM33988-6P-1-3P-E Hydraulic Pump
The PIONEER PM33988-6P-1-3P-E is a high-performance hydraulic gear pump designed for robust operation in heavy-duty mobile and industrial hydraulic systems. As part of Parker Hannifin’s renowned PIONEER product line, this model exemplifies engineering precision and reliability, delivering consistent fluid power for applications requiring durable and efficient hydraulic solutions. The alphanumeric suffix (6P-1-3P-E) indicates specific design variations, including displacement, port configuration, and rotational direction, tailored to meet exact system requirements.
Engineered for longevity and performance under demanding conditions, this pump is ideal for construction machinery, agricultural equipment, and material handling systems where hydraulic efficiency and dependability are critical.
Key Features & Benefits
Robust Gear Design:
Utilizes precision-machined gears and optimized housing to minimize internal leakage and maximize volumetric efficiency, ensuring consistent flow output even under high pressure.
High-Pressure Operation:
Designed to operate reliably at sustained high pressures (e.g., up to 250 bar/3,600 psi), making it suitable for heavy-load applications.
Multiple Displacement Options:
The “6P” designation typically indicates a specific displacement size (e.g., 6 cm³/rev or other standardized value), allowing users to select the exact flow rate required for their system.
Configuration Flexibility:
Suffix variations (1-3P-E) specify critical details such as:
- Shaft Type (e.g., splined, keyed, or flat).
- Port Style (SAE, BSPP, or metric threads).
- Rotation Direction (clockwise or counterclockwise).
- Seal Material (compatible with standard or specific hydraulic fluids).
Durable Construction:
Built with high-strength cast iron or aluminum housing and hardened steel gears to withstand wear, contamination, and harsh operating environments.
Efficient Lubrication:
Optimized internal lubrication reduces friction and heat generation, extending service life and maintaining performance over long operating cycles.
