Product Overview

Our Cartridge Kits for Pumps are engineered to provide efficient, cost-effective, and reliable solutions for your pump repair and maintenance needs. These kits are designed for quick and easy replacement, minimizing downtime and extending the service life of your pumping systems. They come pre-assembled with essential components, ensuring a perfect fit and consistent performance.

Key Product Parameters

• Type: Vane Pump Cartridge Kits (e.g., SQPQ series, Tokimec/Vickers/Denison equivalent)

• Components: Typically include seals, bearings, vanes, cam ring, and other internal rotating elements.

• Displacement: Varies by model (e.g., from 7 ml/r up to 237 ml/r for different SQPQ series).

• Max Operating Pressure: Up to 21 MPa (210 bar) for various models.

• Max Speed: Up to 2700 rpm.

• Compatibility: Designed to replace worn or damaged internal parts of specific pump models without removing the entire pump from its mounting.

Product Advantages and Selling Points

• Ease of Maintenance: Cartridge design allows for quick replacement, often in ten minutes or less, without needing to dismantle the entire hydraulic system.

• Cost-Effective: Offers an economical solution for pump repair, reducing replacement costs compared to full pump replacement.

• Extended Service Life: Manufactured to precise specifications, ensuring long-term operation and preventing secondary damages. Self-compensation for wear and clearances maintains volumetric efficiency.

• Guaranteed Performance: Tested and qualified to ensure safe, reliable, and high performance when properly fitted.

• Reduced Downtime: Minimizes operational interruptions due to fast and simple cartridge exchange.

• Versatility: A small stock of cartridges can service many pump models, simplifying inventory management.

Applicable Equipment

These cartridge kits are primarily applicable to various hydraulic vane pumps, including but not limited to:

• Vickers Vane Pumps (e.g., 2520V, 3525V, 4525V, 3520V, 4520V series)

• Denison Vane Pumps

• Tokimec Vane Pumps (SQP series)

• Caterpillar Pumps (certain models)

• Other industrial and mobile hydraulic vane pumps requiring internal rotating element replacement.

Application Scenarios and Case Studies

Cartridge Kits for Pumps are crucial in a wide range of industrial and mobile hydraulic applications where pump reliability and uptime are critical. They are essential for systems that depend on continuous and efficient fluid power transfer.

• Industrial Manufacturing: Used in hydraulic presses, injection molding machines, machine tools, and other factory automation equipment to maintain consistent pressure and flow for production processes. For example, a manufacturing plant experiencing reduced flow in a hydraulic press replaced the cartridge kit, restoring the machine to optimal operating efficiency and preventing costly production delays.

• Construction and Mobile Equipment: Applied in heavy machinery like excavators, loaders, and cranes for steering, lifting, and propulsion systems. A construction company reported significant savings by using cartridge kits for field repairs on their excavator's hydraulic pump, reducing equipment downtime on project sites.

• Agriculture: Utilized in agricultural machinery such as tractors and harvesters for hydraulic functions like steering, lifting implements, and operating attachments.

• Material Handling: Employed in forklifts, stackers, and conveyor systems that rely on hydraulic power for lifting, tilting, and moving goods.

• Power Generation: Integral to the hydraulic systems of power plants for controlling turbines, valves, and other critical components.

Related Similar Products

Beyond complete cartridge kits, related products that ensure the optimal functioning of hydraulic pumps include:

• Seal Kits: Specific kits containing various seals (O-rings, gaskets, etc.) to prevent leaks and maintain system integrity. Applicable to any pump requiring seal replacement during routine maintenance or repair.

• Overhaul Kits: More comprehensive than cartridge kits, typically including all wear parts for a complete pump overhaul, such as bearings, shafts, and internal components. Suitable for pumps undergoing major repairs after extended use.

• Individual Pump Components: Replacement parts like vanes, cam rings, shafts, and bearings sold separately. Used for targeted repairs when only specific parts are worn or damaged, applicable to a wide range of hydraulic pumps.

• Hydraulic Filters: Essential for maintaining fluid cleanliness and protecting pump components from contamination. Applicable to all hydraulic systems to ensure longevity of pumps and other hydraulic components.

Common Installation & Maintenance Issues and Solutions

Proper installation and regular maintenance are vital for the longevity and performance of pump cartridge kits. Here are common issues and their solutions:

• Issue: Leakage around the cartridge/pump housing.            
  Solution: Often caused by improper installation of O-rings or seals, or damaged seals. Ensure all seals are properly seated and inspect for any damage before installation. Replace worn or damaged O-rings. Verify all fasteners are tightened to the manufacturer's specifications.

• Issue: Reduced flow or pressure output from the pump.            
  Solution: This can indicate a worn cartridge kit, cavitation, or internal pump damage. Inspect the cartridge for signs of wear on vanes, cam ring, or side plates. Ensure the suction line is free from air leaks and that the fluid reservoir level is adequate. Consider replacing the cartridge kit if significant wear is present.

• Issue: Unusual noise or vibration from the pump.            
  Solution: Could be due to misalignment, worn bearings within the cartridge, or cavitation. Check pump-motor alignment. If the noise persists after verifying alignment, the bearings within the cartridge might be failing, necessitating cartridge replacement. Address cavitation by improving suction conditions.

• Issue: Overheating of the pump.            
  Solution: Can result from internal friction due to worn parts, contamination, or operating beyond design parameters. Ensure the hydraulic fluid is clean and at the correct viscosity. Check for proper system cooling. If internal cartridge components are severely worn, replacement is necessary.

• Issue: Cartridge not seating correctly during installation.            
  Solution: Ensure all mating surfaces are clean and free from debris. Lubricate O-rings and seals slightly with hydraulic fluid to aid in seating. Follow the manufacturer's specific instructions for assembly and tightening sequence. Do not force the cartridge into place.
