Dwyer Instruments HP-1 | Hand pump
The Dwyer Instruments HP-1 Hand Pump provides both pneumatic pressure and vacuum from a single compact, portable tool. It generates pressure up to 45 psig (3 bar) and vacuum down to -27 in. Hg (-910 mbar), with fine adjustment control better than 0.0015 psi (0.1 mbar) for precise low-pressure instrumentation calibration.

Product Overview
The Dwyer HP-1 Hand Pump is designed for precise calibration of low-pressure instrumentation where controlled pressure and vacuum generation are required. It provides two pneumatic sources in one compact device, generating positive pressure up to 45 psig (3 bar) and vacuum down to -27 in. Hg (-910 mbar).
The HP-1 is designed for single-handed operation, making it practical for field technicians who need a portable calibration source. Its compact construction allows the pump to be carried easily between test locations while providing the pressure and vacuum control needed for low-pressure instrument verification.
A fine adjustment function allows the user to control the output to better than 0.0015 psi (0.1 mbar). An integrated pressure release valve provides additional control when adjusting or resetting the pressure between calibration points.
The HP-1 is supplied with an instruction manual and two 39-inch (1 m) hoses, each terminating in a 1/4" female NPT connection. One hose can be connected to a reference gauge while the other is connected to the device under test. Dwyer suggests the DPG-022 as a reference gauge for use with the HP-1.
The pump uses nickel-plated brass and anodized aluminum construction and weighs approximately 20 oz (587 g), making it suitable for portable calibration applications.
