14-1B Series Pump | YCY, SCY, MCY, PCY, MYCY | 10ml/r to 250ml/r | High Pressure Axial Piston Pump

14-1B Series High-Pressure Axial Piston Variable Pumps

Product Overview: The 14-1B series is one of the most widely utilized and technically mature axial piston pump ranges in industrial high-pressure hydraulic systems. Covering a comprehensive displacement spectrum from the compact 10ml/r to the heavy-duty 250ml/r, this series meets the power demands of diverse and complex operating conditions. Depending on the control method, the series includes YCY (Pressure Compensated), SCY (Manual Variable), MCY (Fixed), PCY (Constant Power), and MYCY (Remote Control) variants. Renowned for its 31.5 MPa rated pressure, superior suction capability, and robust shock-resistant construction, the 14-1B series is the core power unit for forging presses, metallurgical equipment, mining machinery, and large-scale Hydraulic Power Units (HPU).

Key Technical Advantages:

• Comprehensive Variable Control Logic: Offers pressure compensation, constant power, manual, and electro-hydraulic modes to precisely match system loads and maximize energy efficiency.

• Heavy-Duty High-Pressure Ratings: Rated at 31.5 MPa (4500 PSI) continuous operation with peak capabilities up to 40 MPa. Built with ductile iron housings and reinforced piston groups for long-term stability.

• Superior Suction Capability: Optimized valve plate and cylinder block designs provide excellent suction characteristics at rated speeds, effectively preventing cavitation.

• Low Maintenance Costs: Based on classic industrial standards, internal core components (valve plates, pistons, retainer plates) are highly standardized, facilitating rapid on-site repair and parts replacement.

• Broad Industry Adaptability: Widely utilized in metal forming, injection molding, aluminum extrusion, marine deck machinery, and power plant HPUs.
