APV Cylinder Blocks – New & 2nd Hand Replacement Solutions

APV cylinder blocks are critical components within high-pressure APV homogenisers. They form the core of the liquid end assembly and house the plungers, suction valves, and discharge valves. The condition and precision of the cylinder block directly influence pressure stability, sealing performance, and overall machine reliability.

At Bos Homogenisers, we supply high-quality APV cylinder blocks for a wide range of APV homogeniser models. Our offering includes both New / 2nd hand cylinder blocks, carefully inspected and manufactured to meet OEM-equivalent standards.

If you are searching for specific SPX pump valve article numbers or want to verify which parts match your homogeniser, you can consult our complete spare parts overview at cylinder parts.

What Are APV Cylinder Blocks?

The cylinder block is the main structural component of the homogeniser liquid end. It contains the plunger bores, valve housings, and product channels that enable high-pressure processing.

During operation, the cylinder block must withstand:

• Extreme hydraulic pressure
• Continuous cyclic loading
• Thermal stress from product and CIP cleaning
• Mechanical forces from plunger movement

Because of these demanding conditions, precision machining and correct material selection are essential to ensure long-term performance.

Types of APV Cylinder Blocks

We supply different Types of APV cylinder blocks depending on machine series and application requirements.

Standard Production Cylinder Blocks

Designed for industrial dairy and food processing applications, these blocks are manufactured to original APV tolerances and pressure specifications.

High-Pressure Cylinder Blocks

Suitable for applications operating at elevated pressures, ensuring structural integrity under extreme load.

Laboratory Series Cylinder Blocks

Designed for APV Lab models, offering compact precision machining for R&D and small-scale production environments.

Custom-Machined Cylinder Blocks

For legacy or discontinued APV machines, we provide reverse-engineered or custom-machined solutions based on original dimensions or sample components.

New / 2nd Hand APV Cylinder Blocks

Bos Homogenisers offers both New / 2nd hand APV cylinder blocks to suit different operational and budget requirements.

New Cylinder Blocks

• OEM-equivalent machining accuracy
• Full material traceability
• Ready for installation
• Maximum service life

2nd Hand Cylinder Blocks

• Fully inspected and pressure-tested
• Reconditioned plunger bores (if required)
• Cost-effective replacement option
• Shorter lead times when available from stock

All reconditioned units are carefully evaluated to ensure dimensional accuracy and operational safety.

Common Wear and Damage in APV Cylinder Blocks

Over time, cylinder blocks may develop:

• Plunger bore wear or scoring
• Valve seat erosion
• Corrosion from aggressive cleaning agents
• Fatigue cracking under high pressure

Operating with a damaged cylinder block can lead to:

• Increased plunger packing wear
• Pressure instability
• Product leakage
• Reduced homogenisation efficiency

Timely replacement helps protect associated components such as plungers, valves, and packings.

Compatibility and Precision Engineering

All APV cylinder blocks supplied by Bos Homogenisers are manufactured or refurbished to strict dimensional tolerances. Proper alignment of plunger bores and valve chambers ensures:

• Stable pressure generation
• Uniform load distribution
• Reduced mechanical stress
• Extended service intervals

We support both modern APV Flow machines and legacy APV homogeniser systems.
