Pune, india – Astrophel Aerospace, a pioneering spacetech company based in Pune, is poised to considerably contribute to India’s growing space sector with the successful development of an indigenous cryogenic pump. The innovative pump, designed to power next-generation rocket engines, is currently undergoing rigorous validation by the Indian Space research Organisation (ISRO). This advancement marks a major step towards India becoming a competitive exporter of specialized components for the global space industry.

A ‘Heart of the Rocket’ Developed In-House

The newly developed cryo-pump is capable of achieving speeds of 25,000 RPM and comprises more than 50 intricately engineered components. It’s anticipated to be upgraded into a fully functional turbopump by late 2026, integrating directly into Astrophel’s Astra C1 rocket engine for both first and second-stage propulsion. Experts within the industry often refer to turbopumps as the “heart of a rocket engine,” due to their pivotal role in fuel delivery and engine efficiency.

Unlike conventional systems relying on external power sources, Astrophel’s turbopump design draws power directly from the engine itself. This approach promises more sustainable and cost-effective launches, especially for reusable rocket systems. According to company officials, this innovative technology unlocks potential for long-term efficiency gains and decreased launch expenses.

Global Expansion and Export Opportunities

Astrophel Aerospace is actively forging partnerships to expand its reach beyond the Indian market. A Memorandum of Understanding (MoU) with a United States-based company is currently in the final stages of negotiation.The company is also actively seeking other international collaborations to commercialize its sub-component expertise and address the rising demand in sectors like oil and gas, wich also utilize cryogenic fuels.

“This milestone demonstrates india’s capability to independently develop cutting-edge propulsion technologies at a fraction of the cost seen globally,” stated Suyash Bafna, Co-Founder of Astrophel Aerospace. “ISRO’s certification will not only validate our pump but also solidify India’s position as an innovator in space hardware with significant export potential.”

How does Astrophel’s cryogenic pump contribute too India’s goal of self-reliance in space technology?

The Breakthrough: Astrophel’s Cryogenic Pump Technology

Recent successful testing of Astrophel’s cryogenic pump by the Indian Space Research Organisation (ISRO) marks a pivotal moment for India’s space program. This isn’t just another component test; it’s a significant leap towards self-reliance in critical space technologies and opens doors for private sector participation in orbital infrastructure growth. The pump, designed and manufactured by Astrophel, a burgeoning Indian aerospace company, is crucial for handling liquefied gases – specifically liquid oxygen (LOX) and liquid hydrogen (LH2) – essential propellants for high-performance rocket engines.

Cryogenic propulsion systems are notoriously complex. Maintaining extremely low temperatures (-183°C for LOX and -253°C for LH2) requires complex engineering and materials science. Astrophel’s innovation lies in a novel pump design that improves efficiency, reduces weight, and enhances reliability compared to existing systems. this translates to increased payload capacity and reduced launch costs for future ISRO missions.

ISRO’s Validation and the Meaning of the Test

The rigorous testing conducted by ISRO at its liquid Propulsion Systems Center (LPSC) in Mahendragiri, Tamil Nadu, involved simulating various launch conditions and operational scenarios. The pump successfully demonstrated its ability to deliver the required flow rates and pressures while maintaining cryogenic temperatures.
