Whenever a high pressure calibration pump is needed, we offer several portable, hydraulic test pump models designed to work seamlessly with a reference gauge and process connection. The QTHP reaches test pressures up to 5000 psi (35 MPa) while the XTHP reaches test pressures up to 10,000 psi (70 MPa). Both provide solid, steady pressure without having to lock a stroke-limiting knob, and both feature a unique, balanced design with the pressurized section located below the reservoir, which prevents toppling and adds an unrivaled level of convenience. An integral part of any pressure testing process, our lightweight and durable hydraulic test pumps are compatible to use with most liquids. They’re ideal for pressure transmitter calibration, pressure switch testing, leak testing pressure instruments, and field testing wherever power inputs are unavailable or unsuitable.

QTHP

The sleek design of the new QTHP 35 MPa Hydraulic Hand Pump allows you to reach test pressures up to 5000 psi without having to lock a stroke-limiting knob. It’s compact and easy to use, and because it’s machined from solid stainless steel, it provides steady, stable pressure with absolute precision.

Lightweight and easy to use — weighs only 1.4 kg, and with the pressurized section located below the reservoir, it’s well balanced and easy to hold and pump with one hand
Extremely durable — the liquid reservoir is highly resistant to shock, extreme temperature and chemical exposure, and it’s far less prone to shattering. Sturdy metal handles won’t wear out or break when dropped
Easy to disassemble and repair with standard hand tools
Machined from solid, stainless steel preventing pressure leaks common in housings made from cast material and ensuring consistent, stable pressure
Includes Ralston Quick-test adapters and hoses for quick & efficient connection
Compatible with most liquids (Alcohol, Antifreeze, Ethylene Glycol, Hydraulic Oil, Mineral Oil, Petroleum Based Oil, Windshield Washer Fluid)
Pump comes fitted with a fill plug with over-pressure relief for easy set up.

XTHP

Solid, stable pressure up to 10,000 psi / 70 MPa

The new XTHP is a powerful hand operated hydraulic pump that can quickly generate high pressure up to 10,000 psi / 70 MPa without having to lock a stroke limiting knob. It’s compatible with most fluid media and provides consistent, steady pressure - even when subjected to temperature fluctuations, shocks, impacts, and hazardous chemicals.

Features include:
Balanced Construction
With the pressurized section located below the reservoir, the XTHP manual hydraulic pump is much easier to handle than similar hand operated hydraulic pumps. It’s not top-heavy - you can even hold it and pump with one hand.

Durable Design
The XTHP is a manual hydraulic pump that’s built to last. Its stainless steel components prevent leaks that are common in cast material, and it includes a shock-resistant reservoir, Viton o-ring seals that are impervious to harmful chemicals, and sturdy metal handles that won’t wear out or break when dropped.

Stable Pressure
It's machined from solid stainless steel, preventing leaks and ensuring consistent, steady test pressure.

Quick Priming Piston
Quickly fill the system with fluid media, then easily switch back to the high pressure piston, saving time and muscle.

Media Compatibility
Compatible with most liquids (Alcohol, Antifreeze, Ethylene Glycol, Hydraulic Oil, Mineral Oil, Petroleum Based Oil, Windshield Washer Fluid)

High Pressure Fittings
Includes Ralston Quick-test XT 10,000 psi hose and adapters for fast, safe high pressure connections without a wrench or thread tape.
