HV Hydraulic Hand Pump - Hi-Lo Two Stage, Tank Mount, 500 Bar

The pump for a long stroke with a heavy load waiting at the end of it. Stage one shifts 80 cc a stroke at low pressure to close the gap fast; when the load comes on, the pump changes itself over to the 5 cc stage and gives you 500 bar with a lever you can still work. You do not switch it – it changes over on pressure, which is exactly what you want when both hands are busy. Made in Italy, cast iron body.

Ways to buy

• One part number – no configuration needed.
• Mounts vertically or horizontally on the tank; the lever action changes to suit.
• Tanks 1 to 10 Litre and the 600 mm handle are separate part numbers, linked below.
• Only need one pressure range? The standard single acting range is cheaper.

Specifications

How to choose

• Buy this when you need speed and pressure together. If one range would do, a single stage pump is cheaper.
• Check your ram is rated for what this produces before ordering a 500 bar pump.
• Decide vertical or horizontal before drilling the tank – pull up push down standing, pull out push in lying flat.
• Set the adjustable relief to the weakest component in your circuit, never the pump ceiling.

Technicians Advice

Two things to get right on this one. First the relief: it adjusts from 50 to 500 bar and must be set to your weakest component, never the pump ceiling – find the lowest rated part in the circuit, usually a hose or a cylinder seal, and set below it with a gauge actually fitted, not by counting turns. Second, 500 bar is a different world from 200: fittings and hose that were happy at 200 bar are not necessarily rated for this, and a pinhole at 500 bar injects oil through skin – hunt leaks with cardboard, never a hand. Expect the changeover to feel like the pump suddenly got harder; that is stage two arriving, not a fault. Decide the mounting orientation before you drill because the lever action changes with it, and size the tank generously – the fast stage moves 80 cc a stroke and will find the bottom of an undersized reservoir quicker than anything else in this range.
