Product Description: The TY-YFQ-002S handheld low-pressure pump uses air as the pressure-transmitting medium and provides smooth pressure regulation. This pump is characterized by simple operation, easy maintenance, and minimal risk of leakage. Main Applications: When calibrating low-pressure (low differential pressure) transmitters, sensors, and low-pressure diaphragm pressure gauges, this low-pressure pump is primarily used to provide a stable low-pressure source with sufficient resolution.
Feature 1: Compact size, lightweight, and easy to carry;
Feature 2: Imported seals ensure leak-free operation;
Feature 3: Hand-crank pressurization provides uniform pressure changes and excellent pressure stabilization;
Feature 4: Capable of generating both positive and negative pressure; turning clockwise generates positive pressure, while turning counterclockwise generates negative pressure—simple to operate.
Operation: Both pressure output ports come standard with hose fittings at the factory; the standard connection specification is M20×1.5 female thread. One side connects to a standard gauge, while the other connects to the gauge under calibration. Tighten the exhaust valve. To generate positive pressure, turn the handwheel to its maximum open position and turn it clockwise; to generate negative pressure, turn the handwheel all the way down and turn it counterclockwise. Adjust the gauge under calibration by comparing its pressure reading with that of the standard gauge, using the comparison method for calibration.
