The operation of high pressure liquid pumps is based on the principle of an oscillating pressure intensifier. In simple terms, the principle states that pumping can continue even if the pressure reduces. The pumps function using compressed air ranging from 1 to 10 bar. This allows the pump to continue its operation despite any pressure drops.

The air piston joint is connected to the small diameter plunger. The pressure ratio is the key to determining the maximum outlet pressure. Higher outlet pressures can be gained by simply increasing the pressure ratios.

The pumps are self-priming, and generally, do not require the use of airline lubricator. The liquid flows into the suction chamber due to the upstroke of the drive piston. This suction effect causes the inlet check valve to open, while and the outlet check valve is closed. Down-stroke generates the required pressure for an application. The generated pressure causes the inlet check valve to close, and the outlet check valve to open. The pressure is then transferred to the application equipment.

Maximator pneumatic liquid pumps consist of automatic cycles. The cycles slow down when there is a build-up of pressure. Once the output pressure forces are equalized, the pump stops automatically. The pump restarts if there is an increase in the air drive pressure, or a slight drop in.

Pistons with O-ring seals operate in, fiberglass wrapped cylinders. The cylinder diameter is constant for a particular pump series. The driving medium pushes the piston down on the compression stroke and lifts it on the suction stroke (the M series has a spring return). No drive air lubricant is required as the piston is pre-lubricated during assembly.

In the hydraulic section, the drive piston connects to the hydraulic plunger/piston. Hydraulic pistons have different sizes depending on their nominal ratio. The higher ratio pumps can achieve higher pressures, but have smaller displacements, which translates to less flow per stroke.

During the down stroke, the inlet check valve keeps the liquid in the pump from flowing back into the suction line while it is compressed by the plunger. On the return or suction stroke, fresh liquid is drawn in through the inlet check valve, while the outlet check valve closes.

These check valves control the flow of liquid through the hydraulic section. They are spring-loaded and have a very low cracking pressure, which allows maximum flow during suction. Inlet check valves are closed by the hydraulic fluid pressure on downstrokes. At the same time, the outlet check valves open when the hydraulic pressure in the pump exceeds the pressure in the system after the pump.

This is a pilot operated, unbalanced lightweight spool that cycles the driving pressure first to the top of the driving piston and then to the bottom to cycle the piston. It is actuated through control valves at the beginning and end of stroke, causing the spool to move out of balance and the piston to move up and down.

A hydraulic seal is one of the few parts that wear out. Basically, it prevents fluid from flowing into the actuator while the hydraulic piston is moving back and forth. Seal specifications are determined by the fluid, its pressure and temperature. Most Haskel pumps can be operated without contamination by use of a vent or distance piece between the pump section and the air drive.

Werner Weitner air hydraulic pumps can be used effectively in much case where high pressure is necessary and do not need much maintenance that means lower operating costs. WL series pumps produce 700 bar hydraulic output with only 5 bar air input. WL pumps can be used securely in several fields such as; operating hydraulic cylinders, pullers, presses...

These pumps are controlled by a foot pedal. When pedal is pressed from back side, the air engine starts to pump oil until you release the pedal to stop pumping. When pedal is pressed from front side, pressure relief operation could be completed. For security conditions, WL series hydro-pneumatic pumps are equipped with pressure relief valve just as other Weitner pumps. When pressure reaches the adjusted value, exceeding oil is discharged to tank due to reduce risks.

Air hydraulic pumps work more silently according to electrical or gasoline power units and can be used securely at any gaseous or flammable places. WL pumps also can be used as double acting with the help of a way control valve.

Thanks to the radial configuration of its small piston pump elements, the radial piston pump is suitable for generating pressures of up to 700 bar. The elements are arranged in multiple rings, which enables the pump to generate higher flow rates with lower pulsation.

The type-LP pumps are valve-controlled, alternating plunger pumps based on the principle of a pneumatic-hydraulic pressure amplifier. Depending on the transmission ratio (surface ratio – hydraulic piston : pneumatic piston), they can attain hydraulic pressures of up to 630 bar at an air pressure of 6 bar, for example.

If you want to combine speed with powerful movements (rapid traverse – creeping), a compact, dual-stage system is the right choice for your application. A gear pump feeds the system with a high delivery flow at low pressure, and a radial piston pump with high pressure but a low delivery flow. The two pumps and flanged directly onto one another to form a compact unit.

The pump elements form the basis of the radial piston pump. When working in extremely tight spaces, they can also be installed separately. This allows the user to build almost any form of high-pressure system imaginable.

The double pump element type DMPE integrates both a low-pressure and a high-pressure piston. As soon as the low-pressure limit is reached, an in-built valve depressurises the low-pressure piston. Multistage pumps which can be adapted to a variety of demands can be designed by the user.

Many directional valves for high-pressure applications are designed as seated valves. These are zero-leakage and completely resistant to fluid contamination. The HAWE product range also includes other types of valve that allow you to safeguard or regulate the system pressure.

The valve bank type VB consists of several directional seated valves, connected in parallel. As a ball valve, it is tightly sealed with zero leakage in the closed state. 2/2, 3/2, 4/2, 3/3 and 4/3 directional seated valves can be provided. The valve bank can be fitted directly onto hydraulic power packs with connection blocks.

This is a zero-leakage, cone-seated valve. 2/2, 3/2, 4/2 and 4/3 way functions can be provided. Equipped with the NG6 (Cetop 3) standard connection pattern, the NBVP allows operating pressures of up to 400 bar. Additional options such as position monitoring and a 12 W solenoid are also available.

The BVP17-type directional seated valve can be operated as a 2/2, 3/2, 4/2 or 4/3-way valve at operating pressures of up to 700 bar. Direct actuation options include electro-magnetic, pneumatic and manual (hand lever).

Pressure-limiting valves reliably protect the hydraulic system from being subjected to excessive system pressure. The MV type comes in a wide range of designs and pressures of up to 1000 bar for the high-pressure range.

This valve can be actuated using electric proportional control. It is used for pressure limitation, and also to limit the load pressure on the actuators in the system. It is available as a manifold mounting and as a piping insert valve.

The RHC-type check valve is available as an insert valve in 6 different sizes. Thanks to its range of pilot ratios and optional hydraulic release, it can be used in similar applications to load-holding valves.

The KA-type compact hydraulic power pack is designed for intermittent operation. Its housing contains a tank, an oil-immersed motor, and a high-pressure or dual-stage pump. Valve banks of types BA and VB can be mounted directly on it to form an incredibly compact system solution.

The compact hydraulic power pack type HKL enables you to work in both intermittent and continuous operation. Here too, it is possible to mount valve banks of types BA and VB directly on the power pack. This type of power pack is used primarily for hydraulic tools.

For applications with more demanding flow rate requirements, the standard power pack type FXU is the perfect choice. Thanks to its simple modular configuration, it is available with many options as standard, including high-pressure functions.
