Description

CraftOil QQ-700-2: Portable Dual-Flow Hydraulic Power Unit with Foot Pedal

In stock in Kharkiv, Ukraine — warranty and service in Ukraine — same-day dispatch when available in stock.

The CraftOil QQ-700-2 dual-flow hydraulic power unit is designed for professionals who need high hydraulic pressure, controlled cylinder movement and portability at the job site. Weighing approximately 15 kg, this compact electro-hydraulic power pack combines a two-stage pump, a 2-litre oil reservoir, electromagnetic directional control and a foot pedal.

With a maximum working pressure of 70 MPa (700 bar) and a 1.2 kW electric motor, the QQ-700-2 is intended for compatible double-acting hydraulic tools used in electrical installation, cable maintenance, equipment servicing and industrial field work.

Unlike a single-flow hydraulic pump, the QQ-700-2 can supply hydraulic oil to both sides of a compatible double-acting cylinder. This allows the operator to control both the working stroke and the return stroke under hydraulic pressure, rather than relying solely on a return spring.

The foot pedal helps keep the operator’s hands available for positioning the workpiece, cable or tool. Combined with its compact design and standard 220V single-phase power supply, the QQ-700-2 is a practical option for mobile service teams and installation crews.

Key Benefits of the QQ-700-2 Hydraulic Power Pack

• Dual-flow hydraulic operation: designed for compatible double-acting cylinders with two hydraulic ports.

• Foot-pedal control: allows hands-free activation of the hydraulic control system.

• 700 bar maximum pressure: suitable for hydraulic tools rated for the required pressure.

• Portable design: approximately 15 kg for easier transportation between job sites.

• Two-stage pump: provides a high-flow first stage and a lower-flow high-pressure stage.

• 220V single-phase power: operates from a compatible electrical supply.

• Compact 2 L oil reservoir: reduces overall size and weight for mobile applications.

• Service support in Ukraine: spare parts and technical consultations available through CraftOil.

Why Choose a Dual-Flow Hydraulic Pump for Field Work?

At a workshop, an operator may have room to reposition equipment or disassemble a tool. At a remote installation site, a stuck hydraulic tool can quickly interrupt the entire job.

A dual-flow hydraulic power unit is designed to address applications where the cylinder needs hydraulic pressure in both directions.

Example: A Cable Cutter with a Jammed Blade

If a cable cutter blade becomes stuck while cutting a particularly difficult cable, a single-flow system with spring return may not be able to retract the blade under the existing load.

A compatible dual-acting hydraulic system can apply pressure to the return side of the cylinder, helping retract the blade without relying solely on a spring.

The same principle can be useful with compatible hydraulic pullers, clamping equipment and other tools that require powered cylinder retraction.

How to check your tool: look at the hydraulic cylinder. A cylinder with one hydraulic port is generally configured for single-acting operation; a cylinder with two ports is generally configured for double-acting operation. Always confirm the tool manufacturer’s specifications and hydraulic circuit before selecting a power unit.

Why Use a Foot Pedal?

The QQ-700-2 features foot-pedal control for situations where the operator needs both hands to position and support the work.

Practical advantages include:

• Hands available for positioning: hold the cable, align a crimping die or position the workpiece while activating the hydraulic system.

• More convenient operation: the operator does not need to reach for a control lever on the power unit for every operation.

• Useful in restricted work areas: a foot pedal may be easier to operate than a control mounted on the pump, depending on the installation layout.

• Efficient teamwork: one person can position the tool while another operates the pedal, where the job requires two operators.

Foot-pedal operation does not replace safe work procedures. Position the pedal where it cannot be activated accidentally, keep the cable away from walkways and moving equipment, and ensure the operator can stop the process safely.

Important: Check the Foot Pedal’s Environmental Protection Rating

On construction sites, in cable pits and outdoors, the foot pedal may be exposed to dust, moisture and rain. Before ordering, ask CraftOil to confirm the pedal’s IP protection rating and cable length for the specific production batch.

If your application requires continuous operation in wet conditions, confirm that the equipment is suitable for that environment before purchase. A hydraulic power unit with a manual directional valve may be a more appropriate option for some applications.

Compact Design: What You Should Know About the 2-Litre Oil Tank

The 2-litre reservoir is one of the main design trade-offs of a lightweight portable hydraulic power unit. It helps reduce the size and weight of the equipment, but it also limits the volume of oil available to operate a hydraulic cylinder.

As a preliminary selection guideline, the QQ-700-2 is intended for compatible tools with an approximate working oil displacement of up to 1.5 litres. The actual suitability must be checked against the usable reservoir capacity, cylinder displacement, hose volume, operating stroke and hydraulic circuit.

These figures are guidelines, not universal hydraulic design limits. The required oil volume must be calculated for the actual cylinder and system. Allowance is needed for the oil remaining in the reservoir, hoses and other components.

If the reservoir cannot supply the oil required for the cylinder stroke, the pump may draw air into the system. This can lead to erratic movement, unstable operation and potential equipment damage.

Is the QQ-700-2 Suitable for a Large Hydraulic Press?

Not necessarily. A compact 2-litre power unit may be unsuitable for hydraulic presses with large cylinders, including CraftOil’s Ukrainets oil presses, if their required oil displacement exceeds the unit’s usable oil capacity.

Before connecting the QQ-700-2 to a press or another large hydraulic cylinder, provide the cylinder specifications to CraftOil for a compatibility check.

Oil Temperature and Duty Cycle

A small reservoir has less oil available to absorb and dissipate heat than a larger tank. For this reason, the QQ-700-2 is best considered for intermittent hydraulic cycles rather than automatically assumed suitable for continuous operation throughout a full shift.

For reliable operation:

• Allow cooling breaks between demanding sequences of operations.

• Monitor oil temperature and reservoir level.

• Use the correct hydraulic oil grade specified for the unit.

• Avoid operating with insufficient oil or a system that draws air.

• Follow the manufacturer’s instructions for duty cycle and maintenance.

The right power unit depends not only on maximum pressure, but also on required oil flow, oil displacement, operating frequency and the tool’s hydraulic circuit.

Technical Specifications — CraftOil QQ-700-2

Technical specifications are based on the supplied product data. Confirm the exact configuration, control arrangement and operating requirements against the documentation for the specific unit before purchase.

Can the QQ-700-2 Run from a Generator?

Yes, provided the generator is compatible with the power unit’s electrical requirements.

The motor’s stated current draw is approximately 6 A at 220V. A generator rated at 2 kW may be a starting point for consideration, but suitability cannot be guaranteed from the nominal power rating alone. Motor starting current, generator surge capacity, voltage stability and other connected loads must also be considered.

For field operation:

• Check the generator’s continuous and starting power ratings.

• Start the power unit only when the generator is operating stably.

• Avoid running other high-load equipment from the same generator at the same time unless its capacity has been verified.

• Ensure proper electrical grounding and follow the electrical safety instructions for both devices.

This makes the QQ-700-2 a potential option for sites where a suitable mains connection is unavailable, subject to verification of the power supply.

Why Does the Pressure Gauge Read up to 1,000 Bar?

The QQ-700-2 is specified for a maximum operating pressure of 700 bar, while the supplied glycerine-filled pressure gauge has a scale extending to 1,000 bar.

The higher gauge scale does not increase the power unit’s maximum pressure. The 700 bar limit still applies, and the connected tool, cylinder, hoses, fittings and couplings must all be rated for the intended operating pressure.

Glycerine helps dampen needle vibration, making the pressure reading easier to observe in conditions where the equipment experiences vibration.
