AP200/15 D887-S Bucher High Pressure Gear Pump

Product Overview

The AP200/15D887-S (and AP200/19D887-S) is a high-pressure external gear pump from the Bucher Hydraulics AP200 series. Featuring an aluminum body with cast iron covers, it delivers high volumetric efficiency, low pulsation and long service life. With displacements of approximately 15–19 cm³/rev, continuous pressure of 210 bar and peak pressure of 250 bar, the pump offers direct bolt-on interchangeability with OEM units and undergoes 100% simulated duty testing for reliable performance in construction, agricultural and mobile hydraulic systems.

Key Technical Advantages

1. True drop-in interchangeability: Manufactured to OEM dimensional and porting standards for bolt-on replacement without modifications.
2. High volumetric efficiency with hydraulic compensation: Optimized design minimizes internal leakage for stable, efficient output.
3. Lightweight high-strength construction: Aluminum body combined with cast iron covers provides low weight and high pressure capability.
4. Low pulsation and long service life: Precision gears and bearings ensure smooth operation and extended durability.
5. 100% simulated duty testing: Full pressure, flow, noise and endurance verification before shipment ensures ready-to-install reliability.

Application Areas

• Construction machinery auxiliary hydraulic systems
• Agricultural machinery and tractors
• Loaders, forklifts and material handling equipment
• Sweepers and hydraulic lifting devices
• Open-circuit systems requiring compact high-pressure gear pumps

Expert Maintenance Tips

• Confirm counter-clockwise rotation (S) and flange/port compatibility before installation; use recommended hydraulic oil and maintain proper cleanliness.
• Start at low speed unloaded; check for leaks and noise. Avoid simultaneous maximum pressure and maximum speed.
• Regularly inspect seals and bearings; ensure unrestricted suction lines to prevent cavitation.
• Keep oil temperature and viscosity within recommended ranges; avoid over-pressure operation.
• For special codes, verify the complete order code and consult technical support.
