Thermic Fluid Pumps, Hot Oil Pumps
Thermic Fluid Pumps, Hot Oil Pumps Manufacturer
Product Overview
Our Hot Oil / Cryogenic Pump is engineered for the most demanding thermal applications where fluids must be transported at extreme temperatures—both very high and extremely low. Designed for reliability, safety, and exceptional performance, these pumps are ideal for handling thermal oils up to 350°C and cryogenic liquids down to –196°C such as liquid nitrogen, liquid oxygen, LNG, and other refrigerated gases.
Manufactured with precision-engineered components, advanced sealing systems, and robust metallurgy, our pumps ensure stable performance, minimal leakage, and long service life even under extreme thermal stress.
The Hot Oil / High-Temperature Pump is built using thermally stable materials and heavy-duty bearings designed to withstand continuous operation at elevated temperatures. It features a heat-resistant casing, cooling jacket options, and specially designed mechanical seals that prevent leakage even under severe thermal expansion.
The Cryogenic Pump version is constructed with stainless steel alloys, extended shafts, vapor isolation chambers, and cryogenic-grade seals to ensure optimal performance at ultra-low temperatures. Its design prevents vapor lock, minimizes heat ingress, and ensures stable NPSH conditions for boiling fluids.
Both pump variants feature a hydraulically efficient impeller, ensuring smooth, vibration-free operation and excellent energy performance.
