Palmer Wahl Instrumentation Group: Hand Calibration Pressure Pumps
A new line of hydraulic and pneumatic hand-calibration pressure pumps includes the PV10K hydraulic calibration pressure pump and PV600 combination pneumatic pressure and vacuum calibration pump. The PV10K is a dual-stage pump that includes a selector valve, increasing the priming speed and greatly reducing the effort required to generate high pressures, the company said. The pressure range is 0-10,000 psi or 0-700 bar. The large-volume Pyrex™ reservoir can be filled with distilled water or mineral oil, with an optional brake-fluid model available. A pressure relief valve can be supplied to provide protection to connected instruments, while a swivel reference gauge port allows easy viewing from almost any angle. The PV600 can create a range of vacuum 28 inches of mercury up to 600 psi. Full-time rotation of gauge and process connections maximizes viewing angle during operation. Featuring comfortable, ergonomically designed handles and an adjustable stroke, the unit is efficient, reaching 100 psi with only four pumps, the company said.
