The BL 654 hydraulic pressure calibration pump is a wrench operated pressure pump designed to generate pressure either 85% vacuum or 100MPa (1000 bar). With the special screw press technology, the high pressure can be easily generated, increased and decreased smoothly. A specially designed shut-off valve makes the pressure stability as high as possible during calibration. Without non-returning valve that is usually used in “trouble-maker” hand pump, BL 654 has minimal maintenance required. Two finger-tight connectors installed on the pump allow the user using fingers to connect and disconnect the reference gauge and devices under test quickly and easily without the need for PTFE tape or wrenches.
The BL 654 hydraulic pressure calibration pump is an ideal comparison pump for calibrating pressure test gauges, indicators or transducers in the laboratory. .
• Stable pressure
• Ideal for calibrating large chamber pressure gauges
With specially designed shut-off valve, high pressure could be reached through repeat pumping.
• Durable and Minimal Maintenance
Patented screw press technology, without non-returning valve inside that is usually used in “trouble-maker” hand pump
The high pressure can be generated easily, increased and decreased smoothly
• Extremely low leakage
Patented screw press technology, rather than “easy-to-leak” non-returning valve in hand pump.
• Finger-tight Connectors
Using your fingers to connect and disconnect gauges quickly and easily without the need for PTFE tape or wrenches
