20V8–45V60 Vickers by Danfoss Vane Cartridge Kits

Product Overview

The 20V8, 20V14, 25V17, 25V21, 35V25, 35V30, 35V35, 35V38, 45V50 and 45V60 hydraulic vane pump cartridge repair kits are replacement cartridge solutions for Vickers by Danfoss V Series fixed-displacement vane pumps.

The Vickers V Series uses an intravane cartridge architecture engineered for long operating life, low noise, high volumetric efficiency and simplified field service. Danfoss documentation states that the cartridge is independent of the drive shaft, allowing cartridge replacement and servicing without removing the complete pump from its mounting. Factory-tested cartridge kits are also specified as a means of restoring pump performance after installation.

The replacement range covers:

• 20V8
• 20V14
• 25V17
• 25V21
• 35V25
• 35V30
• 35V35
• 35V38
• 45V50
• 45V60

Each displacement code corresponds to a specific geometric displacement within the Vickers V Series platform. Correct selection must consider pump series, displacement, rotation, seal configuration and exact model code.

Our replacement cartridge program focuses on in-place interchangeability and 100% simulated working-condition testing, helping users reduce machine downtime and avoid unnecessary complete-pump replacement.

Important specification note: The OEM technical material reviewed does not provide one standardized individual cartridge weight for every configuration, nor does it publish a specific material grade for each cartridge component. Therefore, no unverified steel grade or universal cartridge weight is stated here.

Key Technical Advantages

1. Intravane Cartridge Design

The Vickers V Series is based on an intravane cartridge design developed for long service life, low noise, high volumetric efficiency and serviceability. Its cartridge architecture allows maintenance without removing the complete pump from its mounting position.

2. Hydraulic Balancing

The OEM design uses hydraulic balancing to reduce internally generated radial shaft and bearing loads. From an engineering perspective, this contributes to improved bearing loading conditions and long-term durability.

3. Twelve-Vane Architecture

The V Series incorporates a 12-vane system designed to reduce flow pulsation amplitude and system noise. OEM operating data reports typical sound levels by frame size from 62 dB(A) upward under defined test conditions.

4. Factory-Tested Cartridge Concept

Danfoss/Vickers documentation states that factory-tested cartridge kits can provide new pump performance after installation. This makes a matched cartridge assembly more than a collection of loose replacement parts: it is a controlled repair assembly intended to restore critical internal operating relationships.

5. In-Place Interchangeability

For industrial machinery with high downtime costs, the cartridge concept can reduce the need for complete pump removal. This supports faster on-machine service and simplifies replacement logistics.

6. Multi-Displacement Platform

The Vickers V Series provides multiple displacement codes across 20V, 25V, 35V and 45V frame sizes, allowing flow capacity to be selected according to system demand without changing the entire pump architecture.

Application Areas

Typical applications include:

• Plastic injection molding machines
• Hydraulic presses
• Material handling machinery
• Industrial hydraulic power units
• Primary metals equipment
• Machine tools
• Heavy-duty industrial hydraulic systems
• Selected auxiliary hydraulic circuits

Danfoss identifies molding machines, presses, material handling machines, industrial power units and primary metals among V Series application areas.

Expert Maintenance Tips

1. Confirm Rotation Before Installation

Rotation must be matched to the original pump configuration.

• R = Right-hand / clockwise
• L = Left-hand / counterclockwise

The viewing direction is from the shaft end. OEM documentation also specifies that cartridge kits are assembled and tested for the required rotation.

2. Replace or Inspect Sealing Components

When replacing a cartridge, inspect the O-rings, sealing rings and shaft seals, especially when the original pump has exhibited external leakage or abnormal internal leakage.

OEM service instructions require appropriate lubrication of sealing components and correct installation orientation.

3. Prime and Bleed the Pump Correctly

Before initial startup, fill the pump with hydraulic fluid and remove trapped air from the delivery side as required. The OEM procedure emphasizes clean fluid, adequate filling and removal of entrained air during initial commissioning.

4. Maintain Hydraulic Fluid Cleanliness

Full-flow filtration and contamination control are essential for long cartridge life. A new cartridge installed into a contaminated hydraulic system can experience rapid wear on its precision running surfaces.

5. Avoid High-Pressure Cold Starts

High-viscosity cold starts should be managed carefully. OEM operating guidance calls for reduced speed and pressure until the hydraulic system reaches suitable operating temperature.
