If you do pull the pump again, pressurize the pressure port the pump feeds into rear housing and listen for leak. Air is your friend when diagnosing hydraulics. Also, did you insert the suction tube feeding pump from filter side and was seal in rear frame in good shape. Just a few items that come to mind.

This ability to control either the flow or pressure is possible through two different system designs – an open center or closed center systems. The terms open center and closed center are used to differentiate the two system designs as each describes the construction of the directional control valve as well as the type of hydraulic circuit being used within the system. With an open center system, flow is continuous and pressure is intermittent – which is contrary to a closed center system where the flow is intermittent and the pressure continuous.

Within an open center system, as the pump turns flow is generated and then directed back to the tank through a central passage within the directional control valve. When one of the directional control valve’s spools is stroked, the flow is focused toward a load and pressure is created. Once the pressure exceeds the load, the load moves and the hydraulic work is executed.

Flow within a closed center system is also created with the turning of the pump; however, only enough flow is being produced to keep the pump lubricated and to achieve a standby pressure at the directional control valve. In a closed center system, when a spool is stroked a passage is exposed for the flow to enter while a pressure signal is sent from the directional control valve to the pump. This pressure signal informs the pump to then produce the flow needed to complete the hydraulic work.

Traditionally, an open center system is less expensive due to the fixed displacement pump used, which costs less than the variable displacement pump often used for a closed center system. A closed center system, while more expensive perhaps, is usually more efficient as it is not continuously sending oil through the valve when it is not being used. Consequently, less energy and less fuel is used – which results in savings on fuel costs.

Open center systems can be converted to closed center systems and vice versa; although, often times the system is designed as open center or closed center from the get-go. A conversion is not usually done on a current system, specifically an open to close center, as converting an open center directional control valve to a closed center directional control valve requires additional items so that the pump can dump excess flow when not needed.

In order for the pump to dump excess flow, it will require a full-flow dump valve or something similar for when the sectional valve doesn’t need oil. Typically, an electric dump valve is used in conjunction with electrically operated work sections to allow the valve and pump to communicate when flow is not needed; otherwise, the pump will always be sending a larger volume of oil regardless of whether there is work that needs completed.

A fixed displacement pump can be used within a closed center system; however, those building the system will need to have the appropriate knowledge to set up the system correctly with the necessary items. Converting a closed center system to an open center system, on the other hand, requires making an adjustment to the outlet and opening up the internal passage ways within the valve allowing the oil to flow freely through the valve straight to tank. However, not all valves have the option built in to convert between open and closed centers via the outlet.

When specifying a hydraulic system, the type of system design should ultimately be determined based on the application or system requirements. But in order to fully understand whether an open or closed center system is needed – knowing the differences between designs, the hydraulic work requirements and the importance of cost versus efficiency will be the first step.

Hydraulic pumps are an incredibly important component within hydraulic systems. IFP Automation offers a variety of pump and hydraulic system products that deliver exceptional functionality and durability. Our partner Parker’s extensive line of hydraulic pumps deliver ideal performance in even the most demanding industrial and mobile applications. In this post, we are going to spend time discussing pressure compensated and load sensing hydraulic pumps.

Do to the surface area of the servo piston and the pressure exerted on that area, a force is generated that pushes the swash plate of the pump to a lower degree of stroke angle.

The pump tries to maintain compensator setting pressure, and will provide whatever flow (up to it’s maximum flow rate) that is necessary to reach that pressure setting.

The company Sunfab can trace its roots back to Sundins Fabriker, a family company that was established as long ago as 1925 and, for many years, was a successful manufacturer of skis. The first crane was built in 1947 by HIAB, a separate company. As time went on, demands increased for greater capacity, and in 1954, a hydraulic pump was developed that laid the foundation for the future successes of the new company, Sunfab.

These days, Sunfab Hydraulics AB supplies companies with some of the world’s most sophisticated products in its niche market. Products that meet stringent quality, environmental and safety requirements and offer functional solutions.

Our hydraulic Pumps and Motors undergo stringent testing in our own lab and test rigs during production to ensure unsurpassed reliability in the field. Our state-of-the-art production facility employs only the most experienced NC operators and Service Technicians.
