054-51883-0 Parker Denison T67CBAS Vane Pump

Product Overview

The Parker Denison T67CB / T67CBAS Series is a fixed-displacement industrial vane-pump platform covered by Parker’s HY29-0001 technical catalogue. The official Parker documentation defines T67CB displacement codes, shaft configurations, rotation codes, seal classes, operating characteristics, shaft torque limits and dimensional information.

The supplied configuration is:

• T67CBAS B25 B14 B22 3R00 B100
• Parker Order No.: 054-51883-0
• Epiroc / Atlas Copco cross-reference: 57740730
• Configuration: Three pumping sections
• Control Type: Fixed Displacement
• Shaft Code: 3
• Rotation: R — Clockwise
• Porting Code: 00
• Shaft Interface: SAE BB spline, 15 teeth

Parker’s official T67CB ordering code confirms:

• B25 = 79.3 cm³/rev
• B14 = 46.0 cm³/rev
• B22 = 70.3 cm³/rev

The current Parker T67CB documentation does not publish a separate technical page for the historical T67CBAS B25 B14 B22 3R00 B100 triple configuration. Therefore, exact third-stage pressure, speed and efficiency ratings should be confirmed from the original equipment configuration before a final engineering approval.

Our replacement approach is based on in-place interchangeability and 100% simulated working-condition testing, including individual stage flow testing, pressure verification, rotation checks, leakage inspection and combined-load testing.

This distinction is intentional: Parker officially confirms the B22 displacement code but does not currently expose an exact T67CBAS three-stage P3 performance table.

T67CB Reference Operating Data

The current Parker T67CB documentation includes:

• Control Type: Fixed Displacement
• Reference Test Speeds: 1000 / 1500 / 2800 rpm

• Shaft Code 3 Torque Coefficient: 32,670 ml/rev × bar
• Shaft Code 5 Torque Coefficient: 20,600 ml/rev × bar
• T67CB Reference Weight: 26.0 kg

The 2800 rpm value is a Parker T67CB operating-characteristic test condition. It should not automatically be published as the absolute continuous maximum speed for the exact historical T67CBAS triple assembly without configuration-specific confirmation.

Control Type and Operating Principle

• Control Type: Fixed Displacement
• Pump Type: Vane Pump
• Architecture: Cartridge-Based Vane Pump
• Configuration: Triple Pump
• Mechanical Drive: Common input shaft
• Flow Generation: Displacement × rotational speed
• Pressure Capability: Determined by cartridge configuration and duty cycle
• Rotation: R = Clockwise, viewed from the shaft end
• Shaft: Code 3 = SAE BB, 15-tooth spline
• Porting: 00 = Standard porting

Parker’s official T67CB ordering code explicitly defines the shaft, rotation and porting fields.

Key Technical Advantages

1. Three Independent Pumping Sections

The supplied B25/B14/B22 configuration combines three independent displacement sections:

• 79.3 cm³/rev
• 46.0 cm³/rev
• 70.3 cm³/rev

This architecture allows one mechanical prime mover to supply three different hydraulic flow requirements.

2. Parker Denison Cartridge Architecture

The T67 industrial series uses a cartridge-based fixed-displacement vane-pump architecture, with separate ordering codes for displacement, shaft, seal and connection configuration.

3. SAE BB 15-Tooth Splined Shaft

The 3 in the T67CB ordering system identifies an SAE BB 15-tooth spline. This is a critical mechanical-interface parameter for direct replacement.

4. Defined Pressure-Flow Characteristics

Parker provides detailed flow and input-power curves for T67CB cartridges rather than only nominal displacement values.

For example, the B25 section delivers 113.9 L/min at 1500 rpm and 140 bar, while the B14 section delivers 64.0 L/min under the same condition.

5. Shaft Torque Engineering Data

The Parker catalogue provides specific shaft torque coefficients. For shaft code 3, the published limit is 32,670 ml/rev × bar, allowing engineers to check cumulative torque requirements for multi-section pumps.

6. Standard Porting Configuration

The 00 ordering code identifies Parker’s standard porting combination for the documented T67CB ordering system.

7. Low-Noise and Leakage Characterization

Parker’s T67CB technical page includes internal leakage, noise-level, hydromechanical power-loss and permissible-load characteristics. This supports performance-based replacement testing rather than dimension-only inspection. (parker.com)

8. Compact Multi-Circuit Hydraulic Integration

A triple-pump package can supply three hydraulic circuits from one mechanical drive, which is particularly useful in drilling and heavy-duty mobile hydraulic systems.

9. Configuration-Level Interchangeability

Our replacement matching process verifies:

• P1 displacement
• P2 displacement
• P3 displacement
• Shaft spline
• Rotation
• Porting
• Mounting interface
• Overall envelope
• Pressure and flow characteristics

10. 100% Simulated Working-Condition Testing

Typical factory testing can include:

• Individual section flow test
• Pressure test
• RPM verification
• Rotation verification
• Leakage test
• Spline/shaft inspection
• Simultaneous three-section loading
• Input-torque validation

Application Areas

57740730 is identified in secondary Atlas Copco/Epiroc parts references as PUMP, TRIPLE, and is associated with drilling equipment.

Typical application areas include:

• Rotary drilling rigs
• Blast-hole drilling machines
• Mining drilling equipment
• Construction drilling machinery
• Heavy-duty mobile hydraulic systems
• Multi-circuit hydraulic power units
• Drilling auxiliary hydraulic circuits
• Pilot and main hydraulic systems

The exact equipment fitment should be verified against the original machine model and hydraulic schematic.

Expert Maintenance Tips

1. Test Each Pump Section Separately

After service or overhaul, evaluate P1, P2 and P3 independently for:

• Flow
• Pressure
• RPM
• Leakage
• Temperature rise

A total-flow test alone can hide underperformance in one cartridge.

2. Inspect the 15-Tooth Spline

The shaft code 3 uses an SAE BB 15-tooth spline. Inspect the spline for fretting, tooth wear, root damage, looseness and runout before installation.

3. Verify Clockwise Rotation

R means clockwise rotation when viewed from the shaft end. Confirm the rotation before connecting the pump to the machine hydraulic circuit.

4. Keep Suction Conditions Stable

Correct suction-line diameter, clean filtration, sufficient reservoir level and limited inlet restriction are essential to prevent air entrainment and cavitation.

5. Maintain Hydraulic Cleanliness

Inspect filters and hydraulic oil condition regularly. Contaminants can accelerate wear of vane, ring, plate and other cartridge components.

6. Use Controlled Cold Start Procedures

At low temperatures and high oil viscosity, operate initially at reduced speed and pressure until the hydraulic fluid reaches its normal operating viscosity.

7. Do Not Apply P1/P2 Ratings to P3 Without Verification

The official Parker T67CB page provides detailed P1/P2 performance data but does not currently publish the exact P3 rating for T67CBAS B25 B14 B22 3R00 B100.

For procurement, P3 pressure should therefore be confirmed against the original pump configuration.

8. Check Total Input Torque

For a triple pump:

Total Input Torque = P1 Torque + P2 Torque + P3 Torque

The sum must remain within the allowable torque of the shaft and coupling. Parker’s shaft-code-3 torque coefficient is 32,670 ml/rev × bar.

9. Preserve the Original Cartridge Sequence

Do not interchange B25, B14 and B22 positions during overhaul. The cartridge sequence is part of the hydraulic configuration and should be restored exactly.

10. Order by Full Part Number

For a drilling-rig replacement, the safest purchasing description is:

T67CBAS B25 B14 B22 3R00 B100
Parker Order No. 054-51883-0
Epiroc / Atlas Copco 57740730

rather than ordering only “T67CBAS” or “T67 hydraulic pump”.
