Flow Divider, Dump Pump, Cylinder, or Power Unit: How to Choose the Right Hydraulic Component

Four hydraulic components-a flow divider, a 12V dump trailer pump, a tie-rod cylinder, and an electric power unit-compared by function and price to help you pick the right part for your job.

Last updated Aug 17, 2026

Need a hydraulic component but not sure whether you need a pump, a cylinder, a flow divider, or a complete power unit? It's a common trap: you measure the cylinder, buy the pump, and then realize the reservoir or valve is missing. This guide compares four different hydraulic components-a flow divider, a dump pump, a tie-rod cylinder, and an electric power unit-so you can match the right part to the task before you spend.

Quick take

  • Need to split flow between circuits? The Concentric Hydraulic Flow Divider 1300637 is the dedicated component.
  • Need a dump pump? The Dump Hydraulic Pump is made for that job.
  • Need a cylinder? The Double Acting Tie-Rod Cylinder is a straightforward choice.
  • Need a complete power unit? The Single Phase Hydraulic Power Unit is a complete package.

Decision matrix

  • Choose the Concentric Flow Divider if you need to split one hydraulic flow into two or more controlled paths in an industrial or commercial system.
  • Choose the Dump Hydraulic Pump if your project is a dump trailer or dump truck and you want a compact 12V pump with remote control.
  • Choose the Double Acting Tie-Rod Cylinder if you need a 2.5-inch bore, 6-inch stroke, and 2,500 PSI max pressure for pushing or pulling work.
  • Choose the Single Phase Hydraulic Power Unit if you need a 220V AC unit with a 4-gallon reservoir and a 2HP motor for a single-acting lift.

Product notes

Concentric Hydraulic Flow Divider 1300637

Concentric Hydraulic Flow Divider 1300637

This Concentric unit splits one incoming hydraulic flow into two or more output paths, which is essential for consistent pressure or speed across separate circuits. It's in new but open-box condition, so it may have been handled before. That's a limitation if you need a sealed pump, but it shouldn't affect hydraulic function. It's designed for industrial and commercial setups, not for mobile equipment. The unit doesn't do anything on its own; you need a pump, reservoir, and cylinders around it. If your system already has those and needs precise flow control, this is the missing piece. If you're building from scratch, you'll spend more to make this useful.

Dump Hydraulic Pump

Hydraulic Power Unit 12V, Single Acting Dump Hydraulic Pump for Dump Trailer

This pump is built for dump trailers and dump trucks. It's compact, with a 1.5L (1.58Qt) tank, and the copper-wire motor gives a 1.1cc/r output. The remote-control feature is a big plus because you can raise the bed without standing at the pump. It starts quickly and is designed as a direct replacement for 12V DC remote-control systems. Assembly is required, and hydraulic oil isn't included, so plan for setup. The main limitation is that it's a pump for a specific dumping job-it won't drive a cylinder that needs pressure in both directions or serve as a general-purpose power unit. For a dump application, the 12V design and remote control make it a convenient choice.

Double Acting Tie-Rod Cylinder

2.5x6 Hydraulic Cylinder 2.5" Bore 6" Stroke Double Acting Tie-Rod Cylinder

This AMRAP Co cylinder has a 2.5-inch bore, 6-inch stroke, and a 2,500 PSI max operating pressure. It's double-acting, so oil pressure moves the rod in both directions, and the tie-rod construction simplifies servicing. The cylinder extends from 16 1/4 inches to 22 1/4 inches, with a 1-inch pin hole and 3/8-inch NPT ports. At max pressure, it can handle a 12,270-lb column load. It's a straightforward component for applications that fit its size. The limitation is that it's only the cylinder-you need a pump, hoses, and controls to complete the circuit. If your project falls outside this bore and stroke range, you'll want to look elsewhere. But for a 2.5x6 job, this is the direct choice.

Single Phase Hydraulic Power Unit

3450RPM Single Phase Hydraulic Power Unit 4Gal 2HP Motor

This power unit pairs a 4-gallon (16-quart) reservoir with a 2HP motor that runs on 220V AC at 3,450 RPM. The max relief valve setting is 2,950 PSI, and it's designed for gravity-return loads, like a vehicle lift. The unit comes fully assembled and includes operating instructions, so it's closer to plug-and-play than the dump pump. The trade-off is that it's larger and requires a 220V outlet, so it's not for mobile systems. The 2.2KW motor and 4-gallon tank are sized for moderate lift circuits; high-flow applications would need more capacity. If you have a stationary lift that needs a complete power source, this is a practical fit.

Final recommendation by use case

  • For flow control in an existing hydraulic system: Concentric Hydraulic Flow Divider 1300637. The $425.00 price reflects a specialized component that needs the rest of a system around it.
  • For a dump application: Dump Hydraulic Pump. At $143.99, it's a compact remote-controlled option.
  • For a cylinder replacement: Double Acting Tie-Rod Cylinder. The $126.34 price makes it the lowest-priced item in this comparison.
  • For a fixed lift: Single Phase Hydraulic Power Unit. It costs $221.83 and includes a pump, motor, and reservoir.
