HYDRAULIC HAND PUMPS
HYDRAULIC HAND PUMPS
The document provides detailed information about the QTHP and XTHP Hydraulic Hand Pumps, designed for pressure testing with a focus on convenience, durability, and ease of use. These pumps are made in the USA and cater to different pressure requirements, with the QTHP model supporting up to 5,000 psi (35 MPa) and the XTHP model supporting up to 10,000 psi (70 MPa).
- Pressure Testing Applications: Suitable for transmitter calibration, analog gauge testing, and pressure switch testing.
- Design and Durability: Features a high-strength, shatter-resistant reservoir and a solid stainless steel pump body for enhanced chemical resistance and stable pressure.
- Ease of Use: Includes a large fill port, overpressure relief valve, and a balanced design to prevent toppling.
- Quick Connections: Equipped with Quick-test or Quick-test XT ports for fast, tool-free connections.
- Precision Control: Fine adjust piston allows for incremental pressure changes.
- QTHP Model: Max pressure of 5,000 psi, made with stainless steel, aluminum, polysulfone, and brass, with Buna-N and Teflon seals.
- XTHP Model: Max pressure of 10,000 psi, includes a quick priming piston, made with stainless steel, aluminum, and polysulphone, with Viton and Teflon seals.
Ralston Instruments offers complete pressure calibration solutions, including gauges, calibration references, gas controllers, high-pressure hoses, and Quick-test connections. Accessories and complete test kits are available for purchase.

SPEED THROUGH TEST ROUTES WITH CONFIDENCE When it comes to pressure testing, the right hand pump can make all the difference. Convenience is key, so we’ve designed our QTHP and XTHP Hydraulic Hand Pumps to be lightweight, durable, and easy to use. Transmitter Calibration Create stable pressure and control for smooth calibrations without wasting liquid. Pressure Switch Testing Perform switch testing on site with up to 10,000 psi of hydraulic pressure. Analog Gauge Testing Quickly spot check or calibrate analog pressure gauges in the field without taking them out of service.
