Showing Questions of 27

would it be ok to use an 8 h.p. gas engine withe this pump ?

A: yes, 5 HP is the minimum HP required for this pump.

what size motor does this pump take

A: These are rated for being driven by a 5 Hp gas engine.

how much overhung load would a no, 50 sprocket turning 1200 RPM create.

A: These pumps are not rated for side load, and should not be belt/pulley or chain/sprocket driven. As far as the actual question, with so little information it would be impossible to say, even for an engineer who could calculate such things.

Hello, I need components for a press. 5 Hp tefc 3 phase motor 11 gpm. 2 stage pump and components to couple them together. which of the 2 pumps do you recommend for this application? Please give me the pump, motor and couplars item numbers for this application so I can order. Thank you

A: Please contact our Product Support department to provide further details for assistance in choosing your products.

Is this similar to a Northern/Haldex 1012 as a replacement?

A: It is similar, yes.

Can I get this with a 3/4" inlet?

A: No, we do not have that as an option.

looking at our gas powered motor from pto side the crank spins counter clock wise, need all power we can get. do not like running motor at full throttle

A: To get the rated flow and pressure from this pump, it needs to be operated at 3600 rpm by at least a 5 Hp gas engine. The pumps are designed to be direct shaft-to-shaft driven; the pump shaft will turn CW as facing it.

building a hyd press will this pump work with a 10hp 1750rpm electric motor for this application or would a gear pump work better? what would be the gpm & psi ? thanks

A: This is a two-stage gear pump. At 1750 rpm it will take roughly 2.8 Hp electric to push the combined flow of both gear sets (approximately 6.29 gpm) to the 650 psi shift pressure. After that it will take around 2.9 Hp electric to push the low flow/high pressure output (roughly 1.42 gpm) to 3000 psi. Keep in mind unless a gauge is present in the system and monitored closely the shift may occur at an inopportune time during the press and could lead to dangerous situations.

Will this replace my Hyd. pump on my wood splitter. My part # for the pump is 718-04127

A: The specifications seem close. Our pump appears to be pushing more fluid at the high pressure stage than this, so it's not a direct match, but if you have at least 5 Hp it should work.

Can this pump be used for a remote cylinder on a three point hitch on a tractor?

A: Please contact our Product Support department to discuss your application.

Can this pump be mounted vertical?

A: Yes. This pump can be mounted in any orientation as long as it is direct driven, and it would be best if the inlet is flooded; or below the lowest level of fluid in the reservoir.

Can I run 2 hydraulic motors off this pump?

A: Theoretically yes, but when the resistance offered by the load increases the pressure to the unload shift point, the motor speed will drop dramatically; and increase dramatically when the pressure drops below that point. Unless a gauge is viewed constantly in operation to see when that is going to occur, it may lead to damaging or dangerous results. Operation of motors is not typically recommended for two-stage pumps.

What is the rated pressure for this pump?

A: This pump is rated to produce 3000 psi maximum. This is a positive displacement pump and if run on a system with no relief, it will produce enough pressure to destroy itself if capable.

Do you have an electric motor recommendation for this pump? The pump specifies a 5HP motor, but a previous question/answer stated that a 5HP air compressor motor will not work. My hydraulic system is designed to run at less than 600 psi, so the pump will likely never go into the high pressure mode. Do you have a recommendation?

A: Item 10-2621 is a 5 HP compressor motor that is actually 5 HP, and similar motors have worked for customers in the past for running the two-stage pumps of the appropriate flow rate. Often compressor motors that are billed as 5 HP are not truly that powerful, which is why most cannot run a two-stage pump of this size.

What size is the key way on this pump.

A: This pump uses a 1/8" Woodruff key.

Do you carry a 5hp 3600 rpm motor and motor to pump mount that are compatible with this pump?

A: We do not currently have an electric motor that fits those requirements, no.

Will a 2 HP pump at 3400 rpm supply enough power for this pump?

A: No, it will not. It will take just under 5 Hp electric just to shift stages, and approximately that to get the high pressure stage to 3000 psi.

Is the hose barb threaded so it can be removed and replaced by a NPTM tube.

A: No it cannot be changed.

what HP electric motor for running this pump?

A: Due to the characteristics of two-stage pumps, the HP required of an electric motor is very close to that of the stated gasoline engine HP requirement.

What hydraulic fluid is recommended for this pump and will it not function properly if the pump is higher than the fluid level in the tank?

A: Any general purpose hydraulic fluid is fine. To prevent cavitation of the pump it is suggested that oil reservoir be located higher than the pump.

Several years ago I purchased a Barnes pump for my splitter from you Are there parts available for this pump? I need a kit that includes the gears

A: Replacement gears are not available for the log splitter pumps. If yours requires the gears to be replaced, it is time to purchase a new pump.

Where is this pump made? USA or import and if import , what country?

A: These pumps are imported from China.

I am converting a 3pt hitch splitter with 4X24" cylinder. It runs off my 28 h.p. tractors remote hydraulic valves. I will be using a Honda clone 6.5 h.p. engine. Of the two 11 gpm pumps would one pump cycle faster than the other? And what size tank will I need. Tia, Ed

A: The 9-7503-11 has a higher flow in the high pressure stage. A tank of at least 5 gallons would be recommended.

does this pump need to be gravity fed? or the tank mounted high? using for log spliiter

A: Yes it should be mounted where the tank would naturally drain toward the pump.

what kind of metal is pump made of

A: They are cast iron.

what is the warranty on these pumps

A: One year warranty against defects.

How to set relief?

A: The actual relief valve in your system should be in the control valve. This pump has valve that unloads at a preset pressure to shift the pump from Hi flow/Low pressure to Lo flow/Hi Pressure. However it is not advised to alter this as it is preset from the factory.
