700 bar manual hydraulic pumps 

Manual pumps - design, operating principles 

Application of manual pumps

Manual hydraulic pumps are used in various industries and applications where hydraulic force generation is required in the field or in hard-to-reach places. They are often used in repairs, maintenance, lifting heavy objects, industrial plants, car garages, construction, agriculture, and many other fields. Manual hydraulic pumps are portable and independent of an electrical power source. This allows them to be used in places without access to electricity or in emergency situations. Their compact design enables easy transport and handling.

Types of manual pumps

Various variants of manual hydraulic pumps are available on the market, differing in capacity, operating pressure, pump type, and additional features. Some models may have built-in pressure gauges, safety valves, oil backflow prevention valves, or extended handles for greater ease of operation. Manual hydraulic pumps are a reliable tool for generating hydraulic force in a simple and effective way. Their portability, durability, and flexibility make them indispensable in many situations where manual control and precise action in hydraulic systems are needed.

ENERPAC manual hydraulic pumps

Enerpac's range of manual pumps includes high-pressure hydraulic pumps with a pressure of 10,000 psi (700 bar), which are portable, durable, and simple to use. Our pumps are also equipped with safety features to ensure reliable operation while maintaining worker safety. With the most complete line of high-pressure hydraulic pumps available for sale worldwide, you can be sure that Enerpac has the right hydraulic hand or foot pump for your application. Since 1920, when Enerpac introduced the first hydraulic jacks, we have learned what is truly important to tool users. That is why Enerpac pumps are trusted by professionals in countless industrial applications worldwide.

Two-stage hydraulic pump

A two-stage hydraulic pump is a type of pump that operates in two different pressure and flow modes, automatically switching between them depending on the system load. This design allows for combining speed of operation at low pressure with full power and high operating pressure when needed. In practice, this means that a two-stage pump has two displacement stages: First stage (low pressure, high displacement) – the pump quickly moves a large flow of oil at low pressure. In this mode, the cylinder or hydraulic tool extends rapidly until it encounters resistance. Second stage (high pressure, low displacement) – after reaching a specific pressure, the pump automatically switches to high-pressure mode and lower flow, allowing for high work force with precise action. Thanks to this solution, two-stage pumps are exceptionally energy-efficient and fast in operation – they shorten cycle times and reduce operator effort, especially in manual and service applications. These types of pumps are often used in: Enerpac hydraulic tools, lifting and pressing systems, service and workshop systems, mobile hydraulic devices where speed and high force are required in a single system. In the Hydron offer, in the category Enerpac pumps, two-stage pump models are available ( p392 two-stage hydraulic pump ) , which automatically switch between low and high-pressure modes. This solution significantly increases work comfort, reduces energy consumption, and ensures maximum efficiency in daily use.

Manual hydraulic pump

A manual hydraulic pump is a device that allows for the generation of high hydraulic pressure through manual labor. In practice, it is a compact and independent pressure source used where there is no access to electrical or pneumatic power. Thanks to their simple design and high efficiency, these types of pumps are valued in workshops, mobile services, industry, and in situations requiring precise force adjustment. 

Construction of a manual hydraulic pump 

A manual pump typically consists of a body, an operating lever, control valves, and a built-in hydraulic oil reservoir. When pumping with the lever, oil is forced into the system, allowing for the powering of various types of cylinders, hydraulic tools, or testing pressure systems. The device provides stable operation, high sealing, and the ability to obtain pressures of even several thousand bars, depending on the model. These types of pumps are used, among others, in hydraulic jacks, clamping systems, pipe bending devices, press cylinders, testing systems, and during service work in the field. They are invaluable when precision, mobility, and independence from mains power are required. If you need a manual hydraulic pump for a specific application, Hydron offers technical support and assistance in selecting the right model for the cylinder, pressure range, and working conditions.

Double-acting pump

A double-acting pump is a hydraulic device in which oil is pumped both during the stroke of the pumping lever and during its return stroke. This allows for pumping hydraulic fluid in both directions – both when pressing and pulling the pump handle. As a result, the work is more efficient, and pressure can be built up faster and more stably than in classic single-acting pumps. These types of pumps are most commonly used in systems where uniform and rapid powering of double-acting cylinders is required, as well as in tools and devices requiring greater precision and smooth operation. In practice, they perform well in service machinery, lifting systems, presses, workshop installations, and wherever intensive and repetitive pressure generation is needed with minimal operator effort.
