Slack & Parr Metering Pumps Commissioned for Carbon Fibre Plant in India

Why It Matters

The installation strengthens India’s ability to produce high‑performance carbon fibre locally, reducing import reliance and supporting strategic aerospace, defence and infrastructure sectors.

Key Takeaways

• 21 acrylic metering pumps installed for Indian carbon‑fibre plant.
• Pumps sized 1,000, 1,500, 2,000 cc/rev with custom drive units.
• Equipment enables precise polymer flow for PAN precursor fibre production.
• Supports aerospace, defence, infrastructure markets with domestically sourced carbon fibre.
• Highlights Slack & Parr’s role in expanding Indian composites supply chain.

Pulse Analysis

India’s ambition to become a self‑sufficient producer of carbon fibre has accelerated in the past two years, driven by government incentives and rising demand from aerospace, defence and large‑scale infrastructure projects. The new plant, located in an industrial hub, marks one of the country’s largest single‑line capacities for polyacrylonitrile (PAN) precursor fibres, a critical feedstock for high‑performance composites. By localising the entire value chain, manufacturers can cut shipping costs, shorten lead times, and mitigate geopolitical risks associated with importing finished carbon fibre from Europe or the United States.

At the heart of the process is precise fluid handling, where even minor variations in polymer flow can affect fibre quality and tensile strength. Slack & Parr’s acrylic metering pumps deliver high‑accuracy dosing across three displacement sizes—1,000, 1,500 and 2,000 cc per revolution—each mounted on a bespoke drive unit equipped with a custom coupling, gearbox and electric brake. This configuration ensures stable pressure, rapid response to set‑point changes, and minimal pulsation, which are essential for consistent PAN extrusion and downstream carbonisation.

The deployment of these pumps signals a broader shift toward advanced manufacturing equipment in India’s composites sector. Suppliers like Slack & Parr are gaining footholds by offering turnkey solutions that meet stringent aerospace standards, positioning themselves as strategic partners rather than mere component vendors. As domestic carbon fibre output scales, downstream industries can expect lower material costs and greater design flexibility, potentially spurring new applications in electric‑vehicle frames, wind‑turbine blades and defense‑grade structures. The move also underscores the growing interdependence between UK engineering firms and India’s high‑tech industrial roadmap.
