Product Overview
The Dwyer PCHP-1K is a pneumatic calibration hand pump designed for both vacuum and pressure calibration applications. Its wide operating range extends from -28 in. Hg vacuum to 600 psi (40 bar), allowing technicians to verify pneumatic gauges, switches, transmitters, and other compatible instruments using a single portable pump.
The PCHP-1K features built-in 1/8" and 1/4" BSP ports. NPT-to-BSP parallel-thread adapters are supplied with the pump for applications requiring NPT fittings. The male ends of these adapters include bonded washers to support reliable sealing.
Instead of a conventional needle valve, the PCHP-1K uses a Schrader valve, allowing quick and consistent full-open or full-close operation with only a few turns. This provides practical control during repeated calibration procedures without relying on overtightening to improve the seal.
The pump is constructed with stainless steel fittings, an anodized aluminum housing, plastic/rubber handles, and nitrile O-rings. Large check valves and O-rings on both sides of the piston help support leak-free operation during pressure and vacuum generation.
The main difference between the PCHP-1K and the standard PCHP-1 is the included PCHP-HK High Pressure Hose. The PCHP-1K comes with the hose as standard, giving technicians a ready-to-use connection for sensors and calibrators without needing to source the accessory separately.

Frequently Asked Questions
What is the output range of the Dwyer PCHP-1K?
The PCHP-1K covers -28 in. Hg vacuum to 600 psi (40 bar), allowing both vacuum and pressure calibration.
What does the PCHP-1K include that the PCHP-1 does not?
The PCHP-1K includes the PCHP-HK High Pressure Hose as standard. The PCHP-1 has the same pump specifications without this hose accessory.
What type of valve does the PCHP-1K use?
It uses a Schrader valve rather than a needle valve, allowing quick full-open and full-close operation.
What port sizes does the PCHP-1K have?
The pump has 1/8" and 1/4" BSP ports. NPT-to-BSP parallel-thread adapters are included for NPT applications.
What media is the PCHP-1K suitable for?
The PCHP-1K is intended for use with air and compatible gases only.
How does the PCHP-1K help prevent leakage?
The pump uses nitrile O-rings on both sides of the piston, together with large check valves, to support leak-free operation.
What is the PCHP-HK High Pressure Hose used for?
The included PCHP-HK provides a convenient connection between the calibration pump, sensor, and calibrator, making the PCHP-1K ready for calibration applications without separately sourcing the hose.
