Based on HYDR-STAR pumps and valves, we have standard or custom-designed application systems for different scenarios. Our systems can be used for pressure testing, burst testing, and leak testing of various pipelines, valves, and containers; chemical injection and delivery; gas delivery and recovery; pressure gauge and sensor testing and measurement; gas spring, shock absorber, and accumulator inflation; maintaining pressure in dynamic chromatography columns; hydraulic tool power supply, etc. Our systems can be manually operated or controlled by PLC or computers.
