Product Overview
The PV063R1K1T1NMMC is a Parker PVplus (PV+) Series open-loop variable displacement axial piston pump with a nominal displacement of 63 cm³/rev (3.84 in³/rev), rated continuous pressure of 350 bar (5000 psi), and intermittent peak pressure capability of 420 bar (6092 psi) at a maximum speed of 3000 rpm. Equipped with the MMC standard pressure compensator control (integrated pilot valve, constant pressure variable), this model is the flagship configuration in the 63 cc displacement range of the PVplus series — widely deployed in injection molding machines, die-casting machines, and high-pressure hydraulic presses.
The PVplus series features a high-strength cast iron housing with FEM-optimized structural design and an integrated pre-compression chamber that effectively reduces output pulsation and noise levels. The swashplate variable mechanism combined with a modular compensator delivers fast response and high dynamic control accuracy. The series covers displacements from 16 to 360 cm³/rev, with over 20 control options, and modular design enabling field conversion and reduced inventory costs.
The PV063R1K1T1NMMC supports through-drive capability with 100% torque transmission, making it suitable for multi-pump tandem systems. The pump is compatible with standard hydraulic fluids, water-glycol, biodegradable fluids, and fire-resistant fluids (HFC up to 210 bar), demonstrating exceptional media adaptability.
Every PV063R1K1T1NMMC undergoes 100% simulated duty-cycle testing prior to shipment — covering pressure holding, flow output, compensator response, internal leakage, and noise level — ensuring complete drop-in interchangeability with original Parker pumps without installation or plumbing modifications.

Key Technical Advantages
1. High-Strength Cast Iron Housing with FEM-Optimized Structure
The PVplus pump housing is constructed from high-strength cast iron and optimized through Finite Element Analysis (FEA) to achieve structural rigidity while maintaining lightweight design. The integrated pre-compression chamber effectively reduces output flow pulsation, and combined with optimized valve plate flow passages, the PV063R1K1T1NMMC maintains low noise levels (≤96 dBA) even at 350 bar continuous working pressure — particularly suitable for injection molding workshops, food processing, and other industrial environments with stringent noise requirements.
2. MMC Constant Pressure Variable Control — Fast Response and High Precision
The MMC standard pressure compensator with integrated pilot valve automatically adjusts the swashplate angle through pressure feedback, achieving constant pressure variable operation. When system pressure reaches the compensator setting, the pump automatically reduces displacement to only leakage flow, effectively reducing system heat generation and energy consumption. The modular compensator design delivers fast response characteristics and high dynamic adjustment precision, suitable for precision hydraulic systems with strict pressure stability requirements.
3. High Power Density and Wide Speed Range
The PV063R1K1T1NMMC delivers approximately 94.5 L/min at 1500 rpm, with a maximum speed of 2800 rpm. The rated continuous pressure of 350 bar and intermittent peak of 420 bar deliver power density leading the industry. The high-speed capability combined with a wide speed range (minimum 50 rpm) enables operation from fast-cycle to low-speed holding pressure conditions.
4. Modular Design and Through-Drive Capability
The PVplus series employs a modular frame size design with through-drive capability (100% torque transmission), enabling tandem connection of multiple same-series pumps for compact integration of multi-circuit hydraulic systems. The modular compensator enables rapid replacement without pump disassembly, significantly reducing downtime. This design also reduces user inventory costs — spare parts for the same frame size cover multiple displacement and control configurations.
5. Exceptional Suction Performance and Media Compatibility
The PVplus pump delivers excellent self-priming performance and high self-priming speeds, combined with an integral supercharger that ensures adequate suction at high speeds to prevent cavitation damage. The pump is compatible with standard hydraulic fluids, water-glycol, biodegradable fluids, and fire-resistant fluids (HFC up to 210 bar). Seals are NBR standard with FKM upgrade available for wider temperature and chemical compatibility requirements.
Application Areas
Injection Molding Machines: Main pump for clamping, injection, and holding pressure circuits
Die-Casting Machines: Main hydraulic pump for shot and intensification systems
Hydraulic Presses: Four-column and frame-type hydraulic press power sources

The PV063R1K1T1NMMC is ideally suited for heavy-duty industrial hydraulic systems requiring 350 bar continuous working pressure and flow rates in the 90–190 L/min range — the classic configuration for large injection molding machines and high-pressure press power units.
Expert Maintenance Tips
1. Shaft Alignment and Coupling Requirements
Maintain concentricity between the pump shaft and drive shaft within 0.05 mm. Flexible couplings are strongly recommended to accommodate minor angular misalignment. The PV063R1K1T1NMMC features an ISO 3019/2 standard 40mm keyed shaft and ISO 160mm 4-bolt mounting flange, fully interchangeable with original Parker pumps. Never strike the shaft end during installation to avoid damaging internal seals and bearings.
2. Pre-Start Priming Procedure
Before initial startup, the pump must be slowly filled through the case drain port (L1) with clean hydraulic oil to ensure adequate lubrication, cooling, and sealing during startup. Start the pump in jog mode until the pump and piping are sufficiently filled and vented. After complete venting, run at low pressure for 5–10 minutes, check piping and component tightness, then gradually increase to rated pressure.
3. Fluid Cleanliness and Filtration
The PV063R1K1T1NMMC requires fluid cleanliness of ISO 20/18/15 or better. Use filters with a filtration ratio β10 ≥ 75 (per ISO 4572). Avoid suction filters, which increase suction resistance and cavitation risk; if essential, use with a vacuum switch monitor. Install a breather filter with filtration accuracy ≤10 μm on the reservoir and regularly check oil level and fluid condition.
4. Compensator Setup and System Commissioning
The MMC pressure compensator setting should be at least 10–15 bar below the system relief valve setting. In multi-pump systems, stagger the compensator settings to prevent simultaneous adjustment-induced pressure oscillation. The minimum compensator adjustment pressure is approximately 15 bar depending on the specific compensator model. Adjustment must be performed with the pump at full displacement and low operating pressure.
5. Case Drain Line Requirements
The case drain line should be independently routed to the reservoir, avoiding shared return lines. Case drain backpressure must not exceed 2 bar absolute, otherwise case seal damage may occur. Drain line diameter should be sufficiently large to ensure free drainage under cold-start high-viscosity conditions. Installing a pressure gauge or sensor on the drain line is recommended to monitor case pressure status.
