16 GPM 2 STAGE HYD PUMP Brand new, two stage HI/LO pressure hydraulic gear pump. Ideal for applications such as log splitters, presses and other equipment where rapid movement of the cylinder at low pressure is required prior to automatically switching to the high pressure mode to meet load requirements. The change from LO to HI pressure is automatic with the LO stage pressure preset at 650 PSI. Minimum of 8 HP required for gas engine use.
Displacement: 0.256 cu. in. / rev. HI press. stage 1.049 cu. in. / rev. LO press. stage
Pump Type Gear
Pressure: 3000 PSI max.
Speed: 3600 RPM max.
Flow: 4 GPM HI press. stage 16 GPM LO press. stage
Can this pump be used in a pulley driven application, with side loading?
A: No, these pumps are not rated for side loading. They are meant for direct shaft coupling.

Will this pump run at 16 gpm and 1500 psi at the max rpm? If so how much hp would be required?
A: This pump will run at 16 GPM at the max RPM only up to the preset shift pressure of 650 psi. At that point it would shift to the high-pressure stage and flow would drop to 4 GPM. 16 GPM @ 1500 psi continuously would require 16 HP electric, and 22 HP from an industrial gas or diesel engine.

what minimum tank capacity do you recommend for 16 GPM flow rate. This pump would activate two 4x10x1.5 cylinders at the same time. And do you think that it is oversized? Thank-you
A: A general rule of thumb is 1 gallon of tank capacity per gallon of oil being pumped. Since the pump produces lower flow once it shifts you could use a 10 gallon tank. Having 2 cylinders activating at the same time would make good use of the flow capabilities.

can i use a13 hp honda motor withis pump
A: Yes that would be fine. It is more HP than required to get full performance from the pump but the extra will not hurt anything.

How is shaft rotation determined? Looking at the shaft or looking at the head? It states CW.
A: Rotation is facing the input end of the pump shaft. These are normally direct coupled to the crankshaft of a 8 HP gas engine.

Is there a suitable mount to direct couple it to a Honda GX270.
A: The item 1-3239 will work for this.

how do you adjust the low pressure
A: The shifting point is preset from the factory and it is not recommended to change it.

Can this pump be mounted vertical and horizontally?
A: It can be mounted either.

What will be the flow of the pump at a pressure of 1500psi?
A: The flow rate is determined by the speed the pump is turned. The pressure being developed will not affect the flow rate.

Can you give me the brand and model for this pump so I can look up specifications or a technical drawing? or, at a minimum, shaft dia. keyway. and mounting hole/pilot hole dimensions. I will be going from a 1" dia. 3" long motor shaft to this pump and will need to figure the Lovejoy connector and motor/pump mount dimensions. Thanks
A: These are made by Dynamic Fluid Components. Model GP-CBN-160-P-C. Shaft is 1/2" dia. x 1-1/2" long with 1/8" keyway. Mounting is 2" square pattern with 1.78" dia. pilot extension.
