SPX Cylinder Block – High-Pressure Pump Head Blocks for SPX Flow Homogenisers

について SPX cylinder block, also referred to as the pump head block or pressure block, is the structural core of any SPX Flow high-pressure homogeniser. Designed to house critical internal components such as the valves, plungers, and seals, this component must withstand extreme forces during continuous operation. Bos Homogenisers supplies OEM-compatible and custom-engineered cylinder blocks for all major SPX models, supporting industries including dairy, biotech, cosmetics, and food processing.

Whether you are replacing a cracked or worn SPX pump head block or sourcing a replacement pump block SPX for a discontinued model, we offer fast delivery and expert technical support tailored to your system.

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 Is an SPX Cylinder Block?

について SPX cylinder block is a precision-machined steel or stainless steel housing located at the heart of the homogeniser. Its function is to support and align the plungers, valve seats, and all high-pressure seals. The block contains the cylinder bore block SPX section where each plunger reciprocates to pressurise the process fluid.

Common terms for this part include:

SPX Flow cylinder housing

Valve chamber block SPX

Homogeniser pump head block

It is one of the most critical mechanical components in your homogenisation system.

SPX Pump Head Block – Key Functions

について SPX pump head block performs several vital roles:

Contains high-pressure liquid in multiple stages

Supports alignment of plungers and valve assemblies

Ensures seal compression and leak prevention

Withstands repeated thermal and mechanical stress

Over time, fatigue, corrosion, and erosion can compromise the block, requiring inspection or replacement.

SPX Flow Cylinder Housing – Engineered for Pressure & Durability

私たちの SPX Flow cylinder housing units are machined to exacting tolerances to match OEM specifications. Using materials such as 316L stainless steel or hardened tool steel, we ensure each replacement part can handle process pressures of up to 600 bar and beyond.

All cylinder housings undergo quality control checks for flatness, concentricity, and pressure integrity before dispatch. Optional pressure testing certificates are available on request.

Cylinder Bore Block SPX – Plunger Alignment and Sealing

について cylinder bore block SPX forms the internal cavities where each plunger operates. Accurate machining of bore diameters is essential to minimise vibration, ensure proper sealing, and avoid premature packing wear. Excessive scoring or deformation inside the bore often leads to reduced output performance and product contamination.

We offer bore refurbishment services and full replacement cylinder bore blocks for SPX MC-series and legacy Gaulin homogenisers.

Valve Chamber Block SPX – Homogenisation Efficiency

について valve chamber block SPX is the upper section of the cylinder block that contains the homogenisation valves. This part must provide a leak-free seat for valve components, allow accurate flow control, and maintain pressure stability during each compression cycle.

Common causes for valve chamber failure include:

Valve seat pitting or erosion

Surface cracking from pressure fatigue

Thread damage from repeated disassembly

Bos Homogenisers can supply new or remanufactured valve chamber blocks tailored to your valve configuration.

SPX Homogeniser Pressure Block – Materials & Design

について SPX homogeniser pressure block is designed for continuous operation under dynamic loading conditions. To support product hygiene and CIP cleaning, the outer and inner surfaces are polished and passivated.

Available materials:

316L Stainless Steel (standard)

Duplex Stainless Steel (for aggressive media)

Tool Steel (for extremely high pressures)

Our pressure blocks can be supplied bare or preassembled with plungers, seals, and valves upon request.

Replacement Pump Block SPX – When to Replace

Replacement of the replacement pump block SPX is necessary when any of the following conditions occur:

Cracks or structural fatigue in the housing

Irreparable valve seat erosion

Deformed plunger bores beyond repair tolerance

Unrecoverable corrosion or CIP damage

Attempting to reuse a damaged pump block risks product contamination, catastrophic failure, and unplanned downtime.
