Product Overview
The Dwyer CHP-P is a pneumatic calibration hand pump designed for pressure applications up to 100 psi. It provides a practical manual pressure source for technicians performing calibration and verification of pressure gauges, switches, transmitters, and other low-to-medium pressure instrumentation.
The pump is constructed from Acetal plastic and anodized aluminum, which helps inhibit body heat transfer that could otherwise affect calibration readings. This construction makes the CHP-P suitable for applications where maintaining stable readings during calibration is important.
The Series CHP uses oversized check valves to provide controlled and smooth operation. Each piston incorporates two O-rings, helping prevent leakage during pressure generation and supporting consistent operation throughout repeated calibration procedures.
The CHP-P features approximately 4 in³ of displaced volume and includes a 2-foot hose, 1/8" female NPT gauge fitting, and 1/8" NPT pipe plug. The pump has two 1/8" female NPT ports, with one fitted with a removable plug.
An optional hose kit is available for applications where a sensor and calibrator need to be connected without using a tee. For users who require vacuum rather than positive pressure, the CHP-V uses the same general construction and is rated for vacuum generation down to -28.8 in. Hg.

Frequently Asked Questions
What pressure range does the Dwyer CHP-P provide?
The CHP-P generates positive pressure from 0 to 100 psi.
What is the CHP-P used for?
It is designed for calibration and verification of pressure gauges, pressure switches, transmitters, and other pressure instruments.
What helps minimize drift in calibration readings?
The pump's Acetal plastic and anodized aluminum construction helps inhibit body heat transfer that could otherwise influence calibration readings.
How does the CHP-P prevent leakage?
Each piston has two O-rings, helping maintain a sealed system during pressure generation.
What is included with the CHP-P?
The pump includes a 2-foot hose, 1/8" female NPT gauge fitting, and 1/8" NPT pipe plug.
What connections does the CHP-P have?
It has two 1/8" female NPT ports, with one port fitted with a removable plug.
What is the difference between the CHP-P and CHP-V?
The CHP-P generates positive pressure up to 100 psi, while the CHP-V generates vacuum down to -28.8 in. Hg. The appropriate model depends on whether pressure or vacuum calibration is required.
