Hydraulic PTO Gearbox Cast Iron 100lpm / 2850psi 50 Hp

Hydraulic Pto Gearbox Cast Iron 37kw / 50 Hp Transfer Power
This is the big iron 50Hp unit! Able to move up to 100LPM @ 2850Psi
Brand new cast iron made P.T.O gearbox is ideal for adding hydraulic power to tractors and landscape equipment not already equipped with hydraulic circuits, or in need of auxiliary hydraulics. Used to power hydraulic Auger, front-end loaders, mowers, rotary sweepers, etc. These gearboxes are used mainly for connecting hydraulic pumps to the power take-offs of agricultural tractors. It is powerful enough to transfer the load of 100 LPM @ 2850 psi. Please note the last photo is of the gearbox fitted with a Vivoil Group 3 pump. This pump is not included in this sale, it is purely to show how this looks once you mount a pump.
These PTO speed increases can be used with either a Group 2 DIN mount pump, or a Group 3 DIN mount pump. See other listings for a PTO Speed increaser complete with a pump. This listing is just the speed increase box with a pump shaft spline adapter. If you supply your own pump, it needs to be CW, clockwise rotation.
Options are the gearboxes connector to your tractor's 6 splines, 1.3/8" PTO, & also the 'Spline' adapter to suit your pump.
To estimate the correct LPM pump use this simple equation.
If running your PTO at ; 540 RPM x 3 = 1620 RPM . Then multiply the pump CCs. ie. 39cc x 1620 = 63180ccm / 1000 = 63LPM Please allow for approx 20% pump inefficiency, so if after 60LPM, go up to 43cc pump, 1620 x 43 =69LPM less 20% = 56 PM
The standardized PTO output of 540 Rpm is, in this way, increased x 3:1 to optimum operating speeds for the hydraulic pumps. This gearbox and pump offer either direct or remote mounting options to the tractor P.T.O to provide independent hydraulic service. This gearbox itself is rated to provide up to 37 KW or 50 HP to the hydraulic gear pump. This figure is nothing to do with your engine horsepower, only the power the gearbox is able to transfer to the hydraulic pump(see chart below) Female or Male shafts are the same prices.
This comes with standard Female 1-3/8" 6 splined shafts generic to most PTO output shafts. This step-up gearbox has a ratio of 3:1 which means, if your PTO is spinning at 540 RPM, it will step up the speed to 1620 RPM.
The main considerations in choosing the correct size pump for your application; are the amount of Flow required & the pressure required. As the need for higher pressure (PSI) is increased, the power required to produce this pressure rises. It is easy to pump fluid at a high flow rate if low psi is required, but it takes a lot of HP to pump high flow rates at a high PSI.
