A-396A Calibration Pump - Use as a pressure source to calibrate gages, set switches, etc. Has volume adjuster, bleed valve and fine adjustment for pressures up to 72 psi (5 bar). Accessories include barbed fitting, tee connector, three 36 in. lengths of vinyl tubing and instructions.

Fig. 7-3. Exclusive Dwyer over pressure safety traps assure that over range pressures whether gradual or a sudden surge will not force the liquid out of the gage. Over pressures simply float the cork, force the O-ring over the opening and seal the fluid in the gage. When pressure is reduced, cork drops down releasing the O-ring to open trap and gage continues in operation.
