A strong hydraulic PTO pump for a tractor pairs a compatible PTO connection with enough flow and pressure for the implement, making it useful for owners running log splitters, dump trailers, or lifts. The SINOCMP 22GPM leads this group with a stated 22 GPM flow rate, pressure capacity up to 2250 PSI, SAE ports, and a 1-3/8-inch, six-tooth female spline shaft. The other options range from 7.4 to 21.2 GPM, plus a 16.6 GPM model and specialized dump-pump or gearbox combinations.
Those figures are not interchangeable: check your tractor’s PTO interface, hydraulic requirements, and port connections before choosing. This roundup compares the listed specifications and intended applications, while flagging products whose fit is less clearly documented for tractor PTO use.
The SINOCMP 22GPM is the best overall pick for buyers seeking a high-flow hydraulic PTO pump for tractor-powered equipment. It lists 22 GPM, pressure handling up to 2250 PSI, SAE 16 inlet and SAE 12 outlet ports, and a 1-3/8-inch six-tooth female spline shaft. Its stated applications include log splitters, dump trailers, and scissor lifts.
Confirm the shaft and hydraulic requirements against your tractor and implement before buying; its high flow alone does not establish compatibility.

View on AmazonCheck the PTO interface before comparing flow
The most important compatibility trap is assuming that a pump’s flow rating proves it will fit your tractor. The SINOCMP 22GPM and SINOCMP 16.6GPM list a 1-3/8-inch, six-tooth female spline shaft, but the other listings do not all provide the same shaft detail. SAE 16 inlet and SAE 12 outlet ports describe hydraulic connections; they do not confirm the tractor-side PTO spline.
Likewise, a pump advertised for tractors or PTO-driven systems may still require an adapter or a different mounting arrangement. Before ordering, compare the tractor PTO shaft dimensions and spline count with the pump documentation, then verify inlet and outlet fittings and the implement’s connection requirements.
The Generic PTO Gearbox Pump is a different arrangement: it combines a gearbox and pump and lists a 1:3 ratio, so its input and output speeds should not be confused with a direct pump’s stated flow.
Avoid sizing by maximum pressure alone
A higher pressure figure does not by itself mean a pump will operate an implement faster or suit it better. These listings span 7.4 to 22 GPM for several direct-style pumps, while pressure figures range from 2250 to 2500 PSI; the SINOCMP 22GPM lists up to 2250 PSI, whereas the 7.4 GPM Doppy and GELUOXI list 2500 PSI. Flow and pressure serve different requirements, and the listing figures do not establish that every value is available simultaneously under your tractor’s operating conditions.
Match the implement’s required flow and pressure to the pump, then check the tractor’s permitted PTO speed and power. The ATRACYPART C102 lists up to 49 GPM at 1800 RPM, but it is described for dump-truck and trailer systems, not as a straightforward tractor replacement.
Treat application and interface fit as essential alongside headline capacity.
How to Choose a Tractor PTO Hydraulic Pump
Flow rate
Look for a flow rate that meets the implement’s requirement rather than choosing the largest number automatically. The listed direct-style options range from 7.4 GPM on the Doppy, Mixizap, and GELUOXI models to 16.6 GPM on the SINOCMP and 21.2 or 22 GPM on other pumps. Higher listed flow may suit equipment that calls for greater hydraulic output, while a 7.4 GPM model may fit an application specifying lower flow.
The product data does not give a universal tractor or implement match, so consult both manuals before deciding. Do not compare the ATRACYPART’s 49 GPM figure at 1800 RPM as though it were a directly equivalent tractor-pump rating.
Pressure rating
Choose a pump whose pressure rating meets the implement’s stated requirement while remaining within the tractor system’s limits. Listed figures include 2250 PSI for the SINOCMP 22GPM and Mixizap pumps, and 2500 PSI for the Bestauto, VEVOR, SINOCMP 16.6GPM, Doppy, and GELUOXI options. That makes the pressure rating a useful differentiator, but it does not tell you the pressure a particular tractor will deliver in operation.
Buyers whose implement specifies a requirement near 2500 PSI should investigate those listed at that rating; those with a lower requirement may have more choices. Verify the exact operating limits in the product documentation and do not infer suitability from pressure alone.
Shaft and port compatibility
Verify the tractor-side shaft and hydraulic fittings before selecting a pump. The SINOCMP 22GPM and 16.6GPM listings specify a 1-3/8-inch, six-tooth female spline shaft, while several 7.4 GPM listings specify SAE 16 inlet and SAE 12 outlet ports. SAE port sizes help identify hydraulic connections, but they do not establish PTO spline compatibility.
Buyers whose tractor matches the documented SINOCMP shaft can use that detail as a starting point; buyers considering products without a clear shaft specification should obtain confirmation before ordering. Also compare the implement’s inlet and outlet requirements.
A port mismatch or incompatible spline can prevent installation even when the flow and pressure figures look suitable.
Which Tractor PTO Pump Should You Choose?
For a demanding implement that calls for high flow and whose shaft matches, choose the SINOCMP 22GPM Pump: it leads with 22 GPM and lists a 1-3/8-inch, six-tooth female spline. If you need a high-flow option with a stated 2500 PSI limit, compare the SINOCMP 16.6GPM Pump and Bestauto 21.2GPM Pump, checking the tractor and implement requirements first. For a 7.4 GPM application, the Doppy 7.4 GPM Pump lists 2500 PSI and compact dimensions; the Mixizap 7.4 GPM Pump lists SAE ports and 2250 PSI.
The Generic PTO Gearbox Pump suits buyers seeking a combined gearbox-and-pump arrangement, but its pressure is only described as low. Treat the C102 dump-pump options as specialized choices, not confirmed direct tractor fits.

Frequently Asked Questions
How do I confirm that a PTO pump’s spline and shaft match my tractor?
Check your tractor’s PTO shaft size, spline count, and connection type against the pump’s listed shaft details, and verify the implement connection as well. For example, the SINOCMP 22GPM lists a 1-3/8-inch, six-tooth female spline. Do not assume a match from flow rating or intended application alone.
How much tractor horsepower and hydraulic flow does my implement require?
Use the implement manufacturer’s stated flow, pressure, and power requirements, then confirm your tractor can supply them at the required PTO speed. Compare those requirements with the pump’s listed figures; for instance, the SINOCMP 22GPM lists 22 GPM and up to 2250 PSI. Flow alone does not establish compatibility.
Which hydraulic fluid, filtration, and maintenance schedule should I use with a PTO pump?
Follow the pump and implement manufacturers’ instructions for fluid type, filtration, and service intervals. The supplied product information does not specify a universal fluid or maintenance schedule. Keep the system clean, use the prescribed filtration, and inspect connections and fluid condition as directed by the equipment manuals.
How should I compare pump flow and pressure ratings?
Compare both ratings with the implement’s requirements rather than choosing by flow alone. The SINOCMP 22GPM lists 22 GPM and up to 2250 PSI; the SINOCMP 16.6GPM and Bestauto 21.2GPM list a 2500 PSI limit. Verify tractor and implement requirements before treating any rating as a suitable match.
Are C102 dump pumps or gearbox-pump combinations direct tractor replacements?
Do not assume they are direct fits. The C102 listings are specialized dump-pump options, and the Generic PTO Gearbox Pump is described as a combined gearbox-and-pump arrangement with low pressure. Confirm the mounting, PTO connection, hydraulic requirements, and intended system with the equipment documentation before selecting either type.
Final Words
For a demanding implement that requires high flow and matches its shaft, the SINOCMP 22GPM is the clearest overall choice, with 22 GPM and a listed 1-3/8-inch, six-tooth female spline. Compare the SINOCMP 16.6GPM or Bestauto 21.2GPM when their stated pressure limits suit the application. For 7.4 GPM needs, consider Doppy or Mixizap, and verify every tractor and implement connection before deciding.
