CYLINDER HAND PUMPS
CYLINDER HAND PUMPS
The document provides details on cylinder hand pumps designed for precise low pressure or vacuum calibration, manufactured in the USA by Ralston Instruments. These pumps are engineered for simplicity and are suitable for a variety of applications, including low pressure field testing, field maintenance, and differential pressure transmitter calibration.
- Smooth, Stable Pressure Control: Capable of generating pressure up to 125 psi or drawing a vacuum to -15 psi.
- Vernier Adjustment: Allows for incremental pressure changes for precise settings.
- Bleed Valve: Provides extreme control over pressure.
- Durable Construction: Made with anodized aluminum and solid brass fittings, ensuring resistance to rust and corrosion.
- Quick-test Ports: Two universal ports for fast and convenient connections without the need for tools or tape.
- Versatile Options: Easily switch between pressure and vacuum with the DPPV pump.
- DV0V Vacuum Hand Pump: Max vacuum of 23 InHg / 77.9 kPa.
- DP0V Pressure Hand Pump: Max pressure of 125 PSI / 8.6 bar / 860 kPa.
- DPPV Pressure/Vacuum Hand Pump: Combines features of both vacuum and pressure pumps.
- Constructed from anodized aluminum, brass, and stainless steel.
- Equipped with Quick-test connections for ease of use.
Ralston Instruments offers complete pressure calibration solutions, including gauges, calibration references, hand pumps, gas controllers, high pressure hoses, and Quick-test connections. These products are designed to save time and eliminate guesswork in critical pressure testing, maintenance, and repair operations.
