Hello I am new to Hydraulics. And would like to know what size electric motor would I need 4 the barnes 13.5 gal per min 2 stage pump I was looking at a Grainger item# 4k062 Farm duty motor rpm 3450 3hp I would some input. Looking at 4 1/2" cyl 18" stroke . My wood stove will only take 16" wood small but an air tight Elm stove. Thanks alot 4 any input My welder wants me to get it stright b-4 he starts sparking Jay

the part # you gave isfir an elctric motor

That is correct I would like a quite 220V splitter

Sizing the electric motor starts with pump flow and desired maximum working pressure.

HP=GPM X PSI X .000583

With the staged pump it will be the flow of the Low Volume pump that does the splitting at high pressure, usually 3,000 PSI.

I can't seem to find a 2 stage 13.5 GPM Barnes model pump, only an 11/5.5GPM@3600RPM and a 16/8GPM@3600RPM requiring about 5 or 8 HP respectively...

http://www.surpluscenter.com/item.asp?UID=2007071615005...89&catname=hydraulic Northentool also has them same price I believe. I was under the impression That Electric motor was more efficient. I have seen 11gpm barnes 2 stage splitters being sold with 2 hp electric motors? And were advertised as just as power-full as 5 hp gas? I Really Thank You guys for your input Keep it coming. Jay

ELECTRIC MODELS

We have tried many different electric motors and many different configurations to come up with the ultimate electric log splitter. No more Oil changes, No more Trips to the Gas station, and No more loud Noise. Just plug this unit into your existing wall outlet and begin splitting. Our 12 and 16 ton log splitters can be either wired for 110 VAC or 220 VAC which ever works best for your house. These are High Amperage motors so we recommend that you have a 20 AMP circuit breaker on the line you are using to avoid circuit breaker problems.

Our 12 ton comes with a 1.5 HP Motor which gives you the equivalent power of a 6 HP gasoline engine. Our 16 ton comes with a 2 HP motor which gives you the equivalent HP to a 8 HP Gasoline motor. With the high torque of these electric motors, you are not giving up any power, just the messiness and the maintenance of owning a log splitter. Complete One Year Warranty on all Parts.

We have also taken the electric splitters into our larger line of log splitters. Our 20 ton log splitter line is now also available with the electric motor option. These units require a 3 HP motor to drive these unit to top performance. We recommend wiring these units to only 220 VAC since they draw over 25 amps of power.

Key Benefits
1.5 HP Motors draws 15 AMPS at 110 VAC and 7.5 Amps at 220 VAC

2.0 HP Motors draws 18 AMPS at 110 VAC and 9.0 Amps at 220 VAC

3 HP Motors draw 25 Amps at 110 VAC and 12.5 Amps at 220 VAC

12/16/20 tons of Ram Force

2 stage 11 GPM Barnes Pump for a quicker 10 - 14 second cycle time

3, 3 1/2 or 4"" cylinders

20" Maximum log length capability with the 12 and 16 ton units and 26" log capacity with the 20 ton units

12 and 16 ton units have 13" pneumatic tires and a garden tractor pin hitch for towing. Our 20 ton units have high speed trailer tires and a 2" coupler for towing on the road.

Detented return Control valve which locks into reverse position and returns to start position after cylinder is retracted.

It may seem that a gas or diesel engine as the prime mover would have the same power rating as an electric motor. However, the general rule of thumb is to specify an internal-combustion engine with a power rating 21/2 times that of an equivalent electric motor, Figure 2. This is due primarily to the fact that internal combustion engines have different torque-speed relationships than electric motors do. Examining the different torque characteristics will provide the understanding to make a choice based on solid reasoning - rather than putting faith in a rule of thumb ?

I know it's an old post but…for what it's worth. I built an electric log splitter a few years back using a Prestolite MUF-6102 (Barnes 220-0526) electric fork truck motor ( I think it's about 1 – 1.5 hp) with a Barnes pump (106900) & a Parker Series 2H 1 3/4" x 10 1/2" piston and it gives me a solid 3000psi. It splits oak logs faster then my gas powered splitter. I can only burn 16" logs also. A 4 1/2" x 18" cylinder with a 3hp electric motor sounds pretty overkill to me for splitting 16" logs.
My splitter is still going strong! I love it because it's nice & quiet, no gas, oil, cold starting problems or gummy carb to worry about. I fitted it with a 24 volt deep cycle marine battery to make it a portable unit. I'll get 3 hours of continuous splitting from one full charge. I think the only advantage to having a gas splitter is its portability. My splitter doesn’t leave my yard so it's not an issue with me. I'll never own a gas splitter again! Email me if anyone wants pics.
