Pressure pumps

摘要

Palmer Wahl Instrumentation Group launched its new line of hydraulic and pneumatic hand-calibration pressure pumps. The Palmer PV10K Hydraulic Calibration Pressure Pump is a dual-stage pump that includes a selector valve, which increases the priming speed and reduces the effort required to generate high pressures in the range of 0 to 10,000 pounds per square inch (psi). The large-volume Pyrex reservoir can be filled with distilled water or mineral oil, with an optional brake fluid model available. For pneumatic applications, the Palmer PV600 Combination Pneumatic Pressure & Vacuum Calibration Pump can reach 100 psi with only four pumps. Its full-time rotation of gauge and process connections maximizes viewing angle during operation, the company adds.
