The Casappa PLP Series: High-Performance Hydraulic Gear Pump

The Casappa PLP Hydraulic Gear Pump from the Polaris series provides steady, effective fluid power in mobile and industrial uses. It uses a three-part aluminum build and pressure-balanced setup. The Casappa PLP Hydraulic Gear Pump mixes light weight with strong build and good volume efficiency. This line draws on more than fifty years of Casappa knowledge in hydraulic part design. It employs basic CAD 3D modeling and computer tests for better work and steady quality.

Core Design Features of the Casappa PLP Hydraulic Gear Pump

Extruded Aluminum Body and Pressure Balance System

The Casappa PLP Hydraulic Gear Pump uses a tough extruded aluminum alloy body. This body holds one-piece gear, journal, and shaft parts. A pressure balance system boosts volume and mechanical efficiency. It does this by cutting inside leaks over different loads. Thus, it keeps steady flow even in tough spots.

Oversized Bearings and Rear Cover Options

Large bearings lengthen work life under high-pressure setups. Rear covers come in cast iron or aluminum. They cut total weight. At the same time, they keep build strength. This helps light system plans without work losses.

Mounting and Shaft Flexibility

SAE, European, and German standard flanges give wide fit. Drive shaft types include spline, parallel key, and tapered choices. These allow easy mixing into varied gear. Ports come in threaded or flanged kinds for flexible setup.

Performance Specifications of the Casappa PLP Hydraulic Gear Pump

Displacement Range and Group Series

Displacements go from 1.07 cc/rev (0.07 in³/rev) to 91.10 cc/rev (5.56 in³/rev). They cover Groups 10, 20, and 30. This lets exact flow match for set system needs.

Pressure Ratings

Normal steady pressure hits 250 bar (3625 psi). Short pressures reach up to 280 bar (4060 psi). Peaks go to 300 bar (4350 psi) in some models, mainly in Group 20. These numbers fit one-way side-port setups. Reversible models often cap max pressures at about 250 bar (3600 psi). Or they drop 15% in some cases.

Speed Capabilities

Top speeds hit 4000 min⁻¹ in small displacements. For example, Group 10 models up to 5.34 cc/rev do this. Larger units see steady drops in speed. This puts focus on long life and torque give. Low speeds start from 350–650 min⁻¹ based on the model.

Key Model Examples

In Group 10, models like PL.10•1 (1.07 cc/rev) hold 260 bar steady at 4000 min⁻¹. Group 20 models such as PL.20•4 (4.95 cc/rev) reach peak 300 bar at 4000 min⁻¹. Group 30 big displacements like PL.30•90 (91.10 cc/rev) run at 150 bar steady and 2200 min⁻¹ for hard flow jobs. Reversible setups work too. Max pressures usually drop by about 15% from one-way types.

Efficiency and Durability Advantages of the Casappa PLP Hydraulic Gear Pump

High Volumetric Efficiency and Low Noise

The pressure-balanced setup keeps steady efficiency. It cuts power use and heat build. Low noise stays over the full work life. This aids worker ease in closed machines. Tight make limits cut inside leaks for best flow keep.

Robust Construction for Heavy-Duty Use

Built-in outboard bearings manage tough cycles. High-strength stuff fights wear. The light aluminum parts boost fuel save in mobile uses. They also ease setup. Sleeve bearings back the exact-made gear wheels for steady run over long times.

Customization and Valve Integration

Added valve picks and many pump mixes (shared inlet or separate steps) make circuit plans simple. They back electro-hydraulic fan drives or other special needs. Wide picks in shafts, flanges, and ports let custom fixes without hurting main work.

Typical Applications for the Casappa PLP Hydraulic Gear Pump

Mobile Machinery

The Casappa PLP Hydraulic Gear Pump drives build gear like excavators, loaders, and cranes. It gives steady work under changing loads.

Agricultural Equipment

Tractors, harvesters, and tools gain from the small size, good efficiency, and strength in ongoing field work.

Material Handling and Industrial Systems

Forklifts, conveyors, presses, and injection molding machines use the Casappa PLP Hydraulic Gear Pump. They get exact control and long-term steadiness in repeat cycles.

Auxiliary and Specialized Systems

Electro-hydraulic fan drives, on-road vehicles, and boat helpers use its green strength and hard-use skills.

Fluid Compatibility and Operational Guidelines for the Casappa PLP Hydraulic Gear Pump

The Casappa PLP Hydraulic Gear Pump works best with mineral oil-based hydraulic fluids per ISO/DIN rules. Viscosity goes from 12 to 100 mm²/s (suggested) up to 750 mm²/s allowed. Fluid heat spans -25°C to 80°C (up to 110°C with Viton seals). Peaks hit short-term limits of 100–125°C based on seal type (NBR standard, Viton, or HNBR picks). Inlet pressure for pumps goes from 0.7 to 3 bar absolute. Filter needs stress clean fluid to keep work and long life.

Comparison with Related Casappa Series

The Casappa PLP Hydraulic Gear Pump (aluminum body Polaris) puts main on light design and high speeds for mobile jobs. It differs from heavy cast iron types like PH series for higher pressures in ongoing big-displacement uses. This aluminum aim boosts fit while keeping Polaris family match in shafts, flanges, and valves.
