SPH BloX Pump

A configurable OEM pump platform with digital twin–driven architecture
Download the brochure
The BloX Pump Platform is a modular, positive displacement pump solution for integration into OEM analytical, preparative, and fluid handling instruments. It is designed to provide full architectural flexibility to enable our customers to define performance, materials, pressure capability, and scalability in line with their instrument roadmap.
Ultimate customizable HPLC and (semi-) Preparative/Flash Chromatography pump

OEM Reference Design to build your variant

BloX is based on a reference architecture that can be configured and extended without redesigning the full platform. Pump modules are available in kit form and can be fully incorporated into OEM instruments or delivered as standalone solutions.

We support OEM development with:

  • Design and integration guidelines
  • Command and control protocols
  • Service and user documentation
  • Co‑development through Spark’s product development group

This approach enables early feasibility studies of different pump variants.

Configurable Pump Architecture

The BloX platform is built around a modular mechanical and fluidic concept that supports a wide range of configurations. Configuration options include:
Pump architectures

Dual, or binary piston designs

Flow path materials

Suitable for reverse phase and normal phase applications

Seal systems

Optimized for aqueous or organic solvents

Accessories

Self‑flush systems, pulse dampeners, leak sensors, priming valves, filters, gradient modules, active piston wash

Pressure sensing

Configurable with or without integrated pressure sensors

Control electronics

Supplied for OEM integration

Should your application require configurations beyond those described, we encourage you to challenge our team. Our R&D team is fully equipped to develop and validate tailored solutions.

Gradient Architecture

The BloX platform supports binary high‑pressure gradient mixing or quaternary low‑pressure mixing configurations depending on the overall system architecture.

This modular approach ensures flexibility across analytical and preparative workflows while maintaining a consistent pump platform.

Template Specifications (Configurable Ranges)

Digital Simulation – Practical Engineering, not a Buzzword

A Digital Simulation is a virtual representation of the pump that replicates its physical behavior under real operating conditions. Spark’s BloX platform has its own Digital Simulation which is used an engineering tool, embedded into the pump development process.

Using the Digital Simulation, OEMs can:

  • Verify design feasibility before metal is cut
  • Compare alternative pump architectures and configurations
  • Calculate suitable architectures for increasing demands, including:
  • High‑flow solutions (>1 L/min)
  • High‑pressure architecture (>700 bar / 10,000 psi)
  • Reduce hardware iterations, development cost, and time‑to‑market
Applications

The BloX pump platform supports a wide range of liquid‑handling applications, including:

  • Preparative and flash chromatography
  • Protein purification systems, including high‑flow fractionation and buffer delivery
  • Solvent pressurizing for sample extraction workflows
  • Automated sample preparation and extraction systems
  • Dosing and fluid‑metering applications
  • High Performance Liquid Chromatography
  • Analytical, clinical, and laboratory automation instruments

The modular design enables scaling from precision analytical flow to high‑flow, high‑pressure processes within a single platform.

OEM Focused Partnership

Spark designs and manufactures pump solutions exclusively for OEMs. The product development group acts as an extension of the OEM engineering team, supporting:

  • Architecture definition and feasibility analysis
  • Customization of pump platforms and subassemblies
  • Control, service, and integration documentation
  • Long‑term lifecycle and product‑roadmap alignment
