PGP511A0160CD1L7VJ7J5B1B1 Parker Gear Pump 16cc

Product Overview

The PGP511A0160CD1L7VJ7J5B1B1 is a Parker Hannifin PGP/PGM 500 Series PGP511 heavy-duty aluminum external gear pump designed for mobile and industrial hydraulic applications.

Parker’s official PGP/PGM 500 documentation describes the platform as a high-performance, high-efficiency gear-pump and motor family designed for high-pressure operation and low-noise performance. The PGP511 uses a 12-tooth gear profile, pressure-balanced bearing blocks and a wide range of international mounting and port configurations.

The official PGP511 range includes standard displacements from 6 to 31 cm³/rev. Within the configurations specified for this product page:

• PGP511A0160CD1L7VJ7J5B1B1: 16.0 cm³/rev
• PGP511A0270CS1D4VJ7J5B1B1: 27.0 cm³/rev

The engineering ratings are displacement-dependent. The 16 cc configuration is rated for 250 bar continuous / 275 bar intermittent operation at up to 3000 rpm, while the 27 cc configuration is rated for 190 bar continuous / 200 bar intermittent operation at up to 2400 rpm.

Our replacement pumps are developed around the original Parker mechanical and hydraulic configuration and undergo 100% simulated operating-condition testing to verify flow, pressure, internal leakage, rotation and operating stability before delivery.

Key Technical Advantages

Pressure-Balanced Bearing Blocks

Parker identifies pressure-balanced bearing blocks as a key PGP/PGM 500 technology. Their function is to reduce bearing loading and support high efficiency across the operating range, an important consideration for high-pressure external gear pumps.

12-Tooth Low-Noise Gear Profile

The PGP511 uses a 12-tooth gear profile combined with optimized flow metering. Parker states that this design reduces pressure pulsation and contributes to exceptionally quiet operation.

Aluminum High-Power-Density Construction

The PGP/PGM 500 platform is explicitly described by Parker as an aluminum pump and motor family with high performance and high power density. This architecture is particularly useful where hydraulic power must be packaged within weight-sensitive mobile machinery.

Multiple Displacement Options

The PGP511 platform provides standard displacements from 6 through 31 cm³/rev, allowing engineers to select the required flow capacity within a common product architecture.

Pressure Rating Depends on Displacement

The PGP511 family must not be treated as having one universal pressure rating.

For example:

• 16.0 cm³/rev: 250 bar continuous / 275 bar intermittent
• 27.0 cm³/rev: 190 bar continuous / 200 bar intermittent

The difference demonstrates why displacement, speed and pressure must be evaluated together during pump selection.

Flexible International Configuration

Parker provides multiple mounting-flange, shaft and port configurations for the PGP511 platform, supporting global OEM applications and aftermarket replacement requirements.

Application Areas

Parker officially identifies the PGP/PGM 500 Series for:

• Material Handling
• Construction
• Turf Care
• Forestry
• Agriculture
• Industrial Applications

Typical equipment applications include:

Construction Machinery

Parker’s own off-road OEM product information also lists the PGP511 as an aluminum gear-pump platform.

Agricultural Machinery

• Tractors
• Harvesters
• Agricultural implements
• Sprayers

Material Handling

• Forklifts
• Material-handling vehicles
• Lifting equipment

Forestry and Turf Equipment

• Forestry machinery
• Turf-maintenance equipment
• Utility vehicles

Industrial Hydraulic Systems

• Hydraulic power units
• Industrial power packs
• Auxiliary hydraulic circuits
• Automated machinery

Expert Maintenance Tips

Do Not Assume All PGP511 Pumps Are Rated at 250 bar

This is one of the most important selection points.

PGP511A0160: 250 bar continuous

PGP511A0270: 190 bar continuous

The two configurations share the same PGP511 platform but have different pressure/speed envelopes.

Verify Rotation Direction

Parker specifies that the pump must be operated only in the indicated rotation direction. In its ordering-code system, C = clockwise.

Protect the Drive Shaft

Parker’s installation instructions state that the drive shaft must not be subjected to impermissible axial or radial loading. Coupling alignment should therefore be controlled carefully to prevent accelerated gear-unit wear.

Keep the Suction Circuit Airtight

Parker recommends:

• Airtight suction connections
• Stress-free pipe installation
• Thorough internal pipe cleaning
• Removal of welding, bending and machining residues

Parker also identifies contaminated hydraulic fluid as one of the major causes of premature gear-pump failure.

Maintain Hydraulic Fluid Cleanliness

Parker recommends a contamination level of:

ISO 4406 Class 19/17/13

and recommends full-flow return-line filtration.

Commission Without Immediate Full Pressure

Parker’s commissioning procedure calls for:

• Open valves during initial startup
• Zero-pressure startup
• Greatly reduced operating pressure
• Proper venting of the hydraulic circuit
• Gradual transition to normal operating conditions

Do Not Hammer the Coupling Off

Parker specifically instructs technicians to use a suitable puller when removing the drive coupling and warns against levering or hammering the coupling from the shaft because this can damage internal components. The maintenance documentation specifies 46 + 6 Nm for PGP/M 511 fasteners.

Verify the Complete Long-Code Configuration

For:

PGP511A0160CD1L7VJ7J5B1B1

and:

PGP511A0270CS1D4VJ7J5B1B1

do not match only the 0160 or 0270 displacement code.

Also verify:

• Rotation
• Mounting configuration
• Shaft configuration
• Suction-port arrangement
• Pressure-port arrangement
• Seal configuration
• End-cover configuration
• Overall pump length

Parker’s own ordering system separates displacement, rotation, shaft, end-cover and port characteristics, making the complete product code essential for genuine interchangeability.
