The series manual pressure source of the overall open and transparent structures but convenient operation, and the pressure is difficult to leak out. It is composed by a hand pump, valves, check, adjusting-valve and output interfaces for stainless steel. This series medium is oil or pure water. It uses in large pressure scale, regulation of the steady of inspection and improves the staffs work efficiency.
This kind of pressure pump is used commonly to keep the stable high pressure when we use the pressure (differential pressure) transmitter, precision pressure transmitter, general pressure transmitters and other instruments.
