Hydraulics Buying Guide

A hydraulic system is three parts, bought in order. Every job on this page comes down to a pump that makes pressure, a cylinder that turns that pressure into a straight push, and the hose that connects them. BVA builds the whole chain to one number, 10,000 psi, the industry-standard high-pressure rating, so a cylinder, pump, and hose from the line all speak the same language and a fitting from one bolts to another. Pressure times the plunger area gives you force, which is why a compact cylinder moves loads a forklift will not touch. When a single pump has to drive several cylinders at once, a manifold splits the flow so a lift stays level across four corners instead of racking a frame. Buy in that order every time: settle the cylinder to the load, then the pump to the cylinder, then the line and splitters that tie them together. Reaching for the tool first is how shops end up with a ram they cannot feed fast enough.

Size the cylinder by tonnage first, stroke second. The hydraulic cylinders here span 2 to 120 tons, roughly $290 for the smallest up to the mid four figures for a 100-ton ram, so the first cut is capacity. Rate the cylinder above the heaviest real load with margin, the same rule that governs everything else we sell. The second question is stroke, how far the plunger has to travel, since a cylinder that runs out of stroke mid-lift leaves you cribbing and resetting. Most of the low-height BVA cylinders are single acting, meaning oil pushes the plunger out and a spring or the load pushes it back; double-acting models use oil in both directions when you need a powered return or a controlled pull. Hollow-plunger versions let a rod or tensioning stud pass through the center for pulling and holding work. If you would rather not spec the pump separately, the cylinder and pump sets pair a ram with a matched pump out of the box, and cylinder bases and parts add the mounts and base plates that keep a tall cylinder stable under load.

The pump decides what the shop can actually do. A cylinder is only as useful as the power unit behind it, and the pump is usually where the real money and the real constraint sit. The line runs from foot-operated pneumatic treadle pumps around $700, which need only shop air and a free foot, up through electric power units in the high three to four figures for bench and production work, to gasoline power packs past $7,000 for field jobs with no power at hand. Match the pump to the site first: air where you have a compressor and no outlet, electric for repeatable indoor cycles, gasoline for the yard or the road. Then match flow to the cylinder, because a big ram fed by a small hand pump technically works but tests your patience one stroke at a time. When the pump has to run several cylinders together, pair it with a manifold so the flow splits evenly and the load rises square.

Jacking, separating, and pulling: the tools past the ram. Some jobs need a shape a plain cylinder cannot give. A hydraulic jack in the toe-jack pattern, BVA's Magic Lift, carries a low lifting toe that slides under machinery sitting flush on the floor, the classic way to get a lifting point under a press or a motor with almost no clearance, with a head pad on top for normal jacking. To separate rather than lift, spreader wedges drive a hydraulic taper between two flanges to break a gasketed joint open cleanly, and the heavier 14-ton industrial spreader handles the flanges a hand wedge will not move. To draw a part off a shaft, hydraulic pullers, rated here around 6 tons and up, pull seized bearings, gears, and pulleys straight without the hammer-and-pry damage that ruins a shaft. These are the tools that turn a hydraulic system into a maintenance department instead of a bare lift.

Hoses, fluid, and the small stuff that fails first. The hydraulic hoses here are 10,000 psi rubber lines from under $90, and they are worth treating as a wear part; a nicked or aged high-pressure hose is the most common failure point in a portable rig, so keep a spare of the length you actually use. Beyond the line, the hydraulic accessories collection carries the consumables and the odd-job kits: BVA's shear-stable antiwear hydraulic fluid to keep the system clean and the pump alive, a 15-ton nut splitter set that cracks a seized nut off its bolt without a torch, and multi-piece maintenance sets that bundle a cylinder, pump, and fittings for shops standing up hydraulic capability from scratch. Every item in this hub is BVA Hydraulics, stocked as an authorized-distributor line with the full manufacturer warranty, so the pump, cylinder, hose, and coupler you buy across these collections are engineered to work as one system.
