The Taishio Pneumatic Hand Pump, TS40P is a precision-built, hand-operated calibration tool designed to generate controlled pneumatic pressure and vacuum for a wide range of pressure measurement and testing applications. Compact, lightweight, and easy to use, this versatile pump ensures accurate results with minimal operator effort.

Reliable Pressure & Vacuum Generation

Engineered for technicians, engineers, and quality professionals,  produces air pressure up to 10, 25, 35, or 40 bar (depending on model) and vacuum down to -0.9 bar, making it ideal for field and laboratory use.

Precision Control for Calibration

A built-in fine-adjustment vernier enables smooth, incremental pressure or vacuum changes with up to 1 mbar sensitivity, supporting accurate calibration of digital and analog pressure instruments.

Compact, Handheld Design

The lightweight, hand-operated scissor action and low-leakage construction deliver dependable performance with minimal fatigue during extended use. A 1 m nylon hose with swivel adaptor makes connecting to instruments under test simple and efficient.

Wide Compatibility & Easy Setup

Standard 3/8″ (F) BSP gauge/indicator port and 1/4″ (F) BSP test port ensure seamless integration with a variety of calibration adapters, hoses, and test fixtures.

Application

• Calibration of pneumatic pressure gauges and manometers

• Testing pressure transducers / transmitters

• Pneumatic loop checks

• Field and on-site pressure verification
