The PV621, 622 and 623 manual pressure generating base stations
Features
• A uniquely capable, re-arrangeable and self-contained pressure test system
• Advanced pressure generation
— 95% vacuum to 20 bar (300 psi) pneumatic
— 95% vacuum to 100 bar (1,500 psi) pneumatic
— 0 to 1000 bar (15,000 psi) hydraulic
• Stand-alone replacements for hand pumps
• Bench top use as comparators
• Safe and hazardous area versions available
There are three pressure generation stations: the PV621, a pneumatic pressure generator for pressures 95% vacuum to 20 bar (300 psi); the PV622, a pneumatic pressure generator for pressures 95% vacuum to 100 bar (1,500 psi); and the PV623, a hydraulic pressure generator for pressures up to 1,000 bar (15,000 psi). Each pressure station is designed for stand-alone operation as a pressure generator and can replace conventional hand pumps to provide greater efficiency and ease of use. They can also be used on the workbench as comparators.

PV624 hybrid pressure controller base station
The PV624 is a portable hybrid pressure controller base station that combines the advantages of manual pressure generation with fully automatic pressure generation and control.
By utilising interchangeable PM620/PM620T pressure modules and connecting physically or *wirelessly via Bluetooth® with any Bluetooth® **DPI620G electrical calibrator creates a uniquely capable, flexible, self-contained portable hybrid pressure controller
The PV624 automatically selects between fast high volume manual pressure generation and fully automatic precise pressure generation to quickly achieve and accurately maintain a stable setpoint.
To achieve a fast time to up-scale pressure set points (or down-scale pressure set points for negative pressure ranges), the hand pump is requested by the PV624 to be exercised for a portion of the pressure change before automatically isolating the hand pump and seamlessly engaging fully automatic pressure generation to set point.
Down-scale pressure set points (or up-scale pressure set points for negative pressure ranges) are quickly achieved with automatically controlled venting.
Once at set point the PV624 automatically generates and controls the pressure to combat the effect of adiabatic or minor leaks.
