How reciprocating pump technology works
Cryogenic reciprocating pumps use a piston mechanism to transfer cryogenic fluids at high pressure. Their design ensures minimal wear and high efficiency, making them ideal for intermittent and continuous operation in demanding environments.
Our cryogenic reciprocating pump offering
Cryomec® DeltaN pump: the cost compressor
Widely used in cylinder-filling applications and air separation unit (ASU) projects.
Known as a cost-compressor pump, the Cryomec® DeltaN integrates a number of technical innovations that enable it to reduce pump downtime and overall cost of ownership.
The pump’s patented Cryomec® Supercharger technology improves efficiency, leading to very low Net Positive Suction Head Required (NPSHR). The perfect match for strict requirements.
Available for all cryogenic liquids, it offers flow rates of 2 to 85 L/min (0.42 to 22.5 gal/min).
Cryomec® KPS pump: proven technology
With a 40-year track record, the Cryomec® KPS high pressure pump is especially designed for CO2 and N2O filling stations.
Low operating costs, flow rates from 1 to 30 L/min (.21 to 6.6 gal/min), and pressures from 15 to 110 barG (217.56 to 1,595.42 psiG).
It is available with a variety of control systems, automizing operation and reducing any human intervention.
Cryomec® THOR pump: the most reliable on the market
Perfect for high-pressure liquefied gas processes in heavy-duty industries.
Initially developed for LNG, Cryomec® THOR pumps also suit the specific needs of air gas applications, maximizing flow rates, efficiency, and reliability.
Cryomec® LPRP pump: medium pressure, high performance
Dedicated to low/medium-pressure processes with low/medium flow rates, the Cryomec® LPRP pump is widely used by industrial players in the gas supply chain—from processing to distribution, at excellent safety levels.
Hy-Filling 450 and 900
High-performance and cost-effective high-pressure pumps for road and off-road vehicles, heavy mobility, trains, and captive mobility (forklifts) for LH2 applications
