Why use an oscillating booster?

Substituting your high-pressure pump with a miniBOOSTER will give you great savings:

Less investmentLess noiseLower operating costLess space demandingEnergy saving

miniBOOSTERTM

How oscillating boosters work

miniBOOSTER raises the supplied pressure to a higher end pressure, and automatically maintains theend pressure as it compensates for consumption onthe high-pressure side

miniBOOSTERTM

CLOSE

How the miniBOOSTER works (1 …

The oil is led to port IN and passes through the check valves KV1, KV2 and DV to the high-pressure side HIn this situation the oil flowfrom the pump goes right through the miniBOOSTER, and a cylinder on the high-pressure side H will movefast forward

The pilot operated check valve DV enables pressure relief of the high-pressure sideBy connecting port R to thepump and port IN to tank, Pilot string 3 will bepresurized, allowing the oilfrom the high-pressure side H to flow back to tank

Workholding I …

miniBOOSTERTM

miniBOOSTER is commonly used in clamps and support cylinders where it saves energy and space

CLOSE

… Workholding II

miniBOOSTERTM

The miniBOOSTER allowsyou to use the availablehydraulic pressure in themachine tool and to operateany high-pressure functionfrom the low-pressure side

CLOSE

Hydraulic Power Pack I

miniBOOSTERTM

Power Packs are commonlyused for powering:

Bolt Tensioners Nut Splitters Torque WrenchesRailroad ToolsTest Stands Rescue ToolsWorkholdingOil Injection

CLOSE

Off Shore I …

miniBOOSTER is commonlyused in Wellhead Panels,Casing Tongs and RoughNecks

miniBOOSTERTM

CLOSE

… Off Shore II

miniBOOSTERTM

The hydraulic pressure onmost oilrigs is 100-200 bar, but some sub-systems require350–800 bar. To reach a higher pressure theminiBOOSTER automaticallybuilds up the needed end pressure.

CLOSE

… Off Shore III

miniBOOSTERTM

miniBOOSTER generates 700 bar for ROV attachments likecutters, crimpers, spreaders, Bolt Tensioners TouequeWrenches and Linear ActuatorOverride Tools.

CLOSE

Rail Road I …

miniBOOSTER is commonly used for maintenance of railroads by building up a 700 bar high pressure for:

Pulling tracks apart and pushing tracks together for weldingLifting the tracksBending the rails

miniBOOSTERTM

CLOSE

… Rail Road II

miniBOOSTER provides an inexpensive and reliableway of obtaining high pressure since hydraulic power sources providing 120 - 160 bar are often standard:

Rail Road StretchersCutting toolsPower PacksCrimping tools

Mobile I …

miniBOOSTER is commonly used for supplying a highpressure for attachments requiring small cylinders and a high force:
