princess auto hydraulic pump for sale

I bought this pump over a month ago. The pump doesn"t supply more than 2000psi pressure and doesn"t transfer from low press/hi gpm to high press/low gpm @ 650psi. The instruction manual does not indicate where are the adjustment screws for the pressure relief valve and unloader port pressure. HYDROWORKS has no website or help line to assist in troubleshooting/adjustments. So I will have to have it replaced and cross my fingers so the next one works well.

You"ll end up with the pump operating below stated specifications. I haven"t done the calculations but you"d likely end up with around 2000 psi max pressure and reduced gpm flow rates. Not sure about the premature pump and engine failure stated in the above response, both should be fine if you set the pressure relief valve appropriately. Likely better off with a smaller pump suited for the smaller motor.

Usually seal failure happens when the pump rotation is wrong. You want to double check that. Also if you install the motor conversion kit that includes a seal backup ring that will help.

This pump will produce 16GPM on low pressure and 4GPM on high pressure, this means with a 5" bore cylinder with a 2" rod the cycle time on a 24" stroke cylinder will be 14.7 seconds on low pressure and 56.7 seconds on high pressure. In real world terms you don"t always use the full stroke and it is usually a mixture of high and low pressure on the pump. I think out of the available pumps this would be a good choice. This will give you a splitting force of 29 tons. Make sure the structure of the splitter can handle that and you will be good to go. If you want a faster cycle time and less force use a smaller bore cylinder, usually 4" is fine for most applications.It will produce almost 19 tons of force.

These pumps have a 1" inlet port and 3/4" outlet making plumbing straightforward. The large nut standoff is a cover to protect the bypass pressure screw (this should not need to be adjusted, as it controls what PSI the pump switches from high volume- low pressure, to low volume - high pressure at.

I have a 68hp diesel engine that I will be using to build my own tracked backhoe. Would this pump be suited for that engine or is there a better option? I plan on everything being run by hydralics so would this have the capacity to do it?

Yes you need a reservoir for cooling and de-aerating and volume reserve, typically 1.5 times the gpm as a minimum on a mobile unit where you have little volume change and cooling ( like your snowblower) but ideally 3-5 times the gpm so a 30-60gal tank is the minimum you should consider for winter use, This pump takes and will deliver 30hp at 2500psi and max flow, 12hp if you are only running 1000psi at max flow.

In case anyone is wondering, this pump(and I suspect the others of the same make) is a direct bolt on replacement for old massey ferguson Cessna pumps that are impossible to find parts for. Match up your gpm requirements, change the rotation to ccw(using the included instructions) and bolt it on. It even came with the woodruff key. Needed 2 orb to npt fittings to complete my install. Couldn"t be happier

Constructed with high-strength aluminum housing and cast-iron end covers. Ideal for a wide variety of applications, including material handling, aerial lifts, turf care, agriculture and construction. Clockwise rotation is reversible with minor changes to pump configuration (instructions are included). A conversion kit is available to make it into a unidirectional motor.

That would vary based on the system pressure, the RPM that this pump is operated at, and the desired flow rate that you would like it to produce. At 4000 RPM, 3750 PSI, and 16.9 GPM, this pump would require either a 55 HP gas engine, or a 47 HP electric motor.
