pfc hydraulic pump in stock

Southeast FloridaI’m fairly savvy with hydraulics but I’ll be damned if I can figure out how JD can put PFC a valve body on a tractor that has nothing but gear pumps on it. I was thumbing threw the literature on them 5625’s and saw where they offer PFC on the triple deluxe valve bank. I understand perfectly how PFC works on piston pumps with the signal line but a gear pump is beyond my comprehension of how it works without heating the oil threw a pressure relief valve.

Positive Displacement (PD) pumps create pulsation and hydraulic shock due to the reciprocating nature of their stroking action, potentially damaging the entire pumping system.

BLACOH Pulsation Dampeners & Surge Suppressors remove virtually all hydraulic shock, enhancing all-around performance and reliability of fluid flow in industrial and chemical transfer applications.

SENTRY BENEFITS:Whether a piston, plunger, air diaphragm, peristaltic, gear, or diaphragm metering pump, a SENTRY Pulsation Dampener placed at the pump’s discharge will produce a near steady fluid flow up to 99% pulsation and vibration free

Location and proximity are key when installing pulsation dampeners and back pressure valves in any pumping system. A back pressure valve installed in series with a dampener can negate the dampening effect if the valve is opening and closing before the dampener is able to capture a full pulse. This quick-opening effect can also create too much gain within the back pressure valve resulting in inefficiency and chatter.

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.

Eaton mobile open-circuit piston pumps provide a range of options and features to help engineers, operators and machine designers improve density, flexibility and energy efficiency. From the newer X20 portfolio that features greater reliability and productivity in a small, lightweight package, to the variable and fixed displacement options of the PVM, PVH, PVE, PVB and MD PFC Series, Eaton pumps continue to lead the industry in innovation and efficiency.

No matter what your mobile application requires, there’s an Eaton mobile closed-circuit piston pump that’s just right for the job. Designed for vehicles with mid-range pump/motor hydraulic systems, Eaton mobile closed-circuit piston pumps provide safe, precision control in systems and equipment in agriculture, construction, earth-moving, forestry, mining, material handling, turf maintenance, and the automotive and utility industries.

Sometimes bigger isn’t better—but having the perfect fit for the application is. Rated for operating at pressures up to 380 bar (5,500 psi) while powered by engines of less than 82 kW (110 hp), Eaton medium-duty pumps offer the perfect middle ground solution for a variety of applications.

Here is the verbage of the bulletin that Cedar Farm referenced. Explains it pretty well. As far as comparing the capacity/ability of the PPH system to the hydraulic capacity/capabilities of today"s tractors....don"t get your expectations too high. Its really comparing apples to oranges. Back then, most hydraulic motors were simple gear motor setups that didn"t need a lot of pressure to operate...didn"t take much power and didn"t create a lot of heat. Today"s hydraulic motors are usually of axial-piston design which take more pressure to operate and create more heat...although their overall efficiency is much higher. The hydraulic cooling capacity on tractors with PPH systems was much less capacity that what today"s tractors offer. The PPH system allowed a transition away from open center hydraulics to modern closed-center hydraulics, but closed-center load-sensing hydraulics were still in their infancy at that time...we"ve come a long way since then.

To give you an idea about this, a Cyclo planter hydraulic motor took 7-8 GPM to operate the blower fan. IH(and later CaseIH) did NOT recommend using a PPH-equipped tractor to run the Cyclo system directly off the tractor"s hydraulics due to limitations of the PPH system.
