PV140R1K1T1NTCA Parker Piston Pump 140cc 350bar

Model 1: PV140R1K1T1NTCA

Product Overview

The PV140R1K1T1NTCA is a Parker Hannifin PV Series (PVplus Series) open-circuit swashplate-type axial piston variable displacement pump. The PV Series is Parker’s classic product line for medium-to-high pressure hydraulic systems in industrial and mobile applications, covering displacements from 16 to 270 cm³/rev. This model delivers a maximum displacement of 140 cm³/rev.

This model features right-hand rotation (clockwise when viewed from the shaft end) with pressure compensator control, which automatically adjusts displacement in response to system load demand to maintain constant system pressure. K1T1NTCA is the shaft, mounting flange, port configuration, and seal material code. This model utilizes FKM (fluororubber) seals for excellent fluid compatibility.

As a direct OEM-equivalent replacement solution for the Parker PV Series, this product offers complete in-situ interchangeability, strictly adhering to Parker’s original design specifications and mounting interface standards. Every unit undergoes 100% simulated duty-cycle testing, ensuring that key performance metrics—including volumetric efficiency, pressure-flow characteristics, and case drain flow at rated pressure and full displacement—meet or exceed original factory specifications.

Key Technical Advantages

1. Pressure Compensator Control for Stable and Reliable System Pressure
The PV140R1K1T1NTCA features standard pressure compensator control, automatically adjusting the swashplate angle in response to system pressure changes to modulate output flow. When system pressure reaches the compensator set point, the pump automatically reduces displacement to only the small flow required to maintain pressure, significantly reducing overflow losses and system heat generation.

2. 350 bar Rated Pressure with 420 bar Peak Capacity
The PV140 delivers a rated working pressure of 350 bar (5075 psi) with peak pressures up to 420 bar (6090 psi) . At 140 cm³/rev displacement with 2400 RPM maximum speed, it outputs approximately 336 L/min theoretical flow and approximately 196 kW of hydraulic power.

3. 9-Piston Design with Pre-Compression Volume Technology for Low Flow Pulsation and Low Noise
The PV Series features a 9-piston design with pre-compression volume technology. This design effectively reduces outlet flow pulsation and pressure ripple, significantly reducing system noise emissions. The rigid FEM-optimized housing design further reduces noise levels.

4. High-Strength Cast Iron Housing with Hydrodynamic Cylinder Bearings
The high-strength cast iron housing with hydrodynamic cylinder bearings delivers long-term reliable operation under high-load, high-impact conditions. The replaceable bronze composite distribution plate further extends pump service life.

5. Cartridge-Style Control Valves for Field Replacement
The PV Series features cartridge-style control valves that can be replaced in the field without removing the entire pump. This design significantly reduces maintenance downtime and lowers service costs.

6. Two-Piece Design for Easy Maintenance
The PV Series features a two-piece design for easy routine maintenance and service. The integrated air bleed valve enables rapid priming, simplifying first start-up and system air purge operations.

Expert Maintenance Tips

1. Model Confirmation & Pre-Installation Inspection: Prior to installation, confirm the complete model code as PV140R1K1T1NTCA. This is a right-hand rotation configuration (clockwise from shaft end). Verify that the mounting flange specification (SAE B 2-bolt or SAE B 4-bolt diagonal) matches the host machine interface. Manually rotate the shaft before installation to confirm smooth, obstruction-free rotation.

2. Fluid Cleanliness Control: Recommended filtration rating is ISO 18/15 or SAE Class 4. Complete system flushing is mandatory before initial start-up.

3. Pressure Compensator Tuning: This model features standard pressure compensator control. The compensator pressure set point can be adjusted via the adjustment bolt. Perform initial settings under no-load conditions, then gradually increase load to target pressure with fine adjustments. The compensator setting should not exceed the pump’s rated pressure (350 bar).

4. Initial Start-Up & Priming: Before first start-up, pre-lubricate the pump by filling the housing with clean hydraulic fluid through the case drain port. Use the integrated air bleed valve for rapid priming and air purge. Perform a brief jog start (5–10 seconds) to confirm correct rotation direction (right-hand), and check for abnormal noise or leakage. Then正式 start the pump and run at low load for several minutes to purge air from the pump and system lines.

5. Case Drain Port Positioning & Pressure Monitoring: During installation, ensure the drain port is positioned higher than the pump body to prevent oil starvation in the pump chamber after shutdown. Maximum pressure for filter and/or cooling drain line is 7 bar (100 PSI) . Install a pressure gauge on the case drain line for real-time monitoring.

6. Seal Material Confirmation: This model features FKM (fluororubber) seals, suitable for mineral oils and various synthetic hydraulic fluids. For special media (e.g., water-glycol fluids), confirm seal material compatibility.
