Hydraulic Training Seminars 2014 - Photos

Both Christchurch and Auckland Training seminars sold out again this year. People for the Auckland seminar came from wide and far - Dubai, Gisborne and Wellington.

For the Christchurch seminar we had people from the Hawkes Bay, Nelson through to Dunedin. SI Class of 2014

We had fun with lively discussions on hydraulics, how the different components worked, why hydraulics fail and how to get longer life out of machinery and general fault finding. Our hydraulic training seminars are such a mine of information on hydraulics that even our competitors attend! 

Some of the highlights - Hands on learning with parts and cross sections of parts passed around the class, stories of Luigi. The tour of Hyspecs products - for some it was like being a kid in a candy factory!

In Auckland another highlight was the tour of the Hytech manufacturing facility where our Manifolds are designed and manufactured.

In Christchurch the test equipment tour had some service engineers wheels spinning.

Some of the feedback we received "my knowledge has greatly increased and taken another persons perspective", "was excellent, can now apply this knowledge at work in practical applications", "The Topics covered gave a good general base on hydraulic components, applications and systems". See more photos on our Face book pageNI Class of 2014Hytech Tour

Hydraulics Overheating?

As summer approaches the extra heat in the atmosphere puts more pressure on hydraulic systems.

Hyspecs recommends, as operating temperature is 60 degrees Celsius. Do not test with your hand, as even touching for a split second is too hot. Instead use the temperature gauge to get an accurate reading.

Eaton recommends a maximum system operating temperature of no higher than 82 degrees Celsius. Keeping your system cool will increase the life of your system and save you money in the long run.

In a perfect hydraulic world all energy put into a system could be transferred to the job at hand, whether it is a cylinder, motor or some other hydraulic machinery. However we are lucky if we get 65-75% of the input energy turned into useful work. The rest gets turned into heat, noise and vibration.

The loss of power can be attributed to many things:

  • High pressure drop across hoses, orifices and valves
  • Mismatched motor sizes in a pressure compensated system
  • In-built inefficiencies in pumps and motors
  • Poorly designed hydraulic systems 

Try as we may to get the system 100% efficient we will never do it, so we are usually stuck with two options to overcome heat:

 Emmegi Water Cooler

  • Build a large oil tank to dissipate the heat. This is usually the easiest and cheapest option if designing a system from new. Hyspecs recommends a tank size of at least 2.5-3 times the maximum flow of oil in the system (not applicable to closed loop systems where the designer can get away with a much smaller tank). 
  • Install a hydraulic oil cooler cable of cooling approximately 30% of the system input power. Oil coolers typically come as either air/oil or water/oil variety. The air/oil coolers are pretty much the same as a car radiator with either an electric or hydraulic fan blowing over the fins to cool the oil flowing inside the radiator. Oil/water coolers are designed to have oil running through a large outer tube with a separate series of smaller tubes running inside this, containing flowing fresh or slat water which carries the heat away from the oil.  Emmegi Air cooler

Hydraulic Motors - how stuff works

Hyspecs provides a full range of hydraulic motor with a brief explanation of each hydraulic motor category below. Click the headings for more detailed information.

Gear Motor

Consit essentially of two intermeshing toothed gears enclosed in a common housing.

Gerotor/Geroler Motor

The H series motor uses a Gerotor while the rest of the Char-Lynn motors use a Geroler.

Piston Motor

Axial piston Motors are displacement machines in which the pistons are arranged in parallel to the axis of rotation of a cylinder barrel.

Swash-Plate Motor

In this version, the cylinder barrel is driven and, as a result, the pistons which are located and guided in the barrel rotate with it.

Bent Axis Motor

With this type of hydraulic motor, the cylinder barrel is driven by the pistons which in turn are themselves driven by the drive flange.

Wobble-Plate Motor

With this type of hydraulic motor, a so-called wobble plate is driven by the input or drive shaft.

For a more detailed description of each of these motors please visit our "How stuff works" motor series page or contact one of our Hyspecs Engineers 0508 497 732.

Variable Volume Oil Reservoirs

Hyspecs can now offer you an alternative to bulky oil tanks and using large quantities of hydraulic oil.

Variable Volume Oil ReservoirIf you need to:

  • reduce the size and weight of your hydraulic system
  • reduce the risk to the environment in the event of an oil leak
  • stop oil contamination from dusty, humid or salty air
  • increase the life of your fluid and components by up to 5 times

then we have a solution for you with the innovative Variable Volume Reservoir (VVR).

For example your standard 200L hydraulic tank could be replaced with a VVR weighing 16 kg when filled with oil! These reservoirs have been used successfully since 2008 on various hydraulic systems such as drill rigs and are suitable for mobile, industrial and marine applications where weight or quantity of oil stored is critical.

VVR On PowerpackThe VVR allows your hydraulics to be run in a closed loop sealed system. The VVR also slightly supercharges the pump inlet reducing the risk of cavitation, beneficial when working at altitude or on steep angles. A correctly sized oil cooler must be used and Hyspecs offers a full range of air and water coolers ex-stock.

Standard equipment on the VVR is low level switch, air bleed valve, support brackets and isolation ball valve. Additional options available are overboard relief and instrumentation manifold.

If you would like more information then please contact Craig at Hyspecs Auckland on 09 274 9985 or email

In Control With Hyspecs

Hydraulic Valve: HS9508Welcome to the first Hydrafile for 2013. Wow what a summer we have been having. I can't remember the last time we had such a good run of beach weather. Of course not everyone is happy and with drought conditions upon us the farmers are in a tough position. Personally we are in water conservation mode at home as our tanks slowly dwindle. We have our fingers crossed for some decent rain soon.

Hyspecs Excavator Valving has been featured in the latest Deals on Wheels magazine. Read the article in full in this months Hydrafile:

"Excavators are a versatile machine with a plethora of attachments available - turning a standard digger into a machine capable of just about anything. When adding a new attachment to an excavator, you need to be able to control it. If an auxiliary valve is available, that can be used. If not, another hydraulic valve capable of controlling the new attachment will get the job done."

So what's a Scoobi? The acronym Scoobi was coined by one of our service engineers a few years back and stands for "Self Contained Old Oil Beautifying Implement". The Scoobi was designed to transfer oil from one vessel to another, whilst extracting contamination from the oil in the process. Typically used for transferring old oil from a tank that needs cleaning, during system maintenance and for filling tanks in new systems. Even new oil contains contaminates so it is recommended that a new drum of oil be filtered before going into the tank. The Scoobi provides a clean and easy way of doing this.

ScoobiFeatures and Benefits
• Dual filtration in and out, 10 micron, useful for separate water and particle filtration ensuring ultra clean oil
• Gauge for indication that filter needs changing
• Rubber tyres and contoured handgrip for manoeuvrability and easy transportation
• IP65 rated on/off switch
• Assembled from locally sourced components for ease of service
• Manufactured by Hyspecs
• Relief valve protection
• Approximate dimensions 1m(h) x 0.5m(w) x 0.4m(d)

• Transfer oil at 20 l/min
• Powered by a single phase 0.75 kW electric motor with lead & plug
• Oil is pumped via a Galtech gear pump

Nett price for the Scoobi is $3300 + GST. We currently have Scoobi's in stock and lead time from ordering if not in stock is typically 5 working days. We also hire out our workshop Scoobi at the rate of $50 per half day and $100 per day plus filters. Hose assemblies can be manufactured to your specifications.

Poclain Selector Valves

Hyspecs now stocks the Poclain KV range of electronic 3 and 6 port selector valves.

Electronic selector valves are often used in a situation where a new piece of hydraulic equipment has been added to an existing machine. For instance a 6/2 way valve can divert oil from the tilt function on an excavator to another auxiliary function, at the press of a button.

Stocked valves range in size from 3/8" to 1" (BSP ports), as either 12 or 24 VDC with a manual over-ride option on all. An external drain port is drilled as standard, which allows higher pressure and/or flow in most cases. This port can be plugged if 
not needed. All valves are open on changeover.

Specification Information:












3/8" BSP, 12/24 VDC





1/2" BSP, 12/24VDC





3/4" BSP, 12/24VDC






3/8" BSP, 12/24VDC





1/2" BSP, 12/24VDC, NG6





1/2" BSP, 12/24VDC, NG10





3/4" BSP, 12/24VDC





1" BSP, 24VDC





For more information download the Poclain catalogue by  clicking here (see pages 37-39 (3port), 77-87(6-port)).

Our sales engineers are available to offer expert guidance on the correct method for applying these valves to your application. They can be contacted by phone (see the numbers on the contact us page) or email at

HYTECH-Hydraulic Manifolds

Hytech logoHytech is the manufacturing division of Hyspecs NZ, located within the same building at 32 Crooks Road Auckland. Hytech manufactures standard & custom hydraulic manifolds. 

Hydraulic manifolds are used in conjunction with cartridge valves to provide an integrated circuit where complex functions can be performed, equal to that of most conventional control components. The manifold itself is usually some form of aluminium alloy or steel with cavities machined to accept the cartridges. The cartridges control the flow and pressure of the oil to the machines various hydraulic components such as motors and cylinders.

The advantages of this technology become clear once it is examined in more depth

hydraulic manifolds 11. Complex functions can be performed by one integrated circuit. This can replace many discrete components.
2. Hosing or pipe-work is greatly simplified, resulting in lower costs and fewer potential failures
3. Pressure, return and function ports can be positioned where most convenient for the end user. Customising the block to the particular machine.
4. Circuit confidentiality is enhanced, since the design cannot be easily traced
without resorting to exotic X-Ray methods.
hydraulic manifolds 25. Installed costs are usually lower than discrete components.
6. Skilled technicians are not usually needed to install the circuit.
7. Maintenance is simplified due to rapid cartridge interchange-ability. Failure of the block itself is rare.
8. Circuit versatility industry common cavities allow cartridges with differing functions to be substituted in the block. Therefore altering the circuit to customer specific requirements.
9. The completed circuit is usually lighter than individual components.
10. The completed circuit is usually more compact than individual components.
11. Virtually any circuit can be incorporated into a cartridge block.

Hytech provides Hyspecs with standard hydraulic manifolds that are used in every day circuits, such as relief and counterbalance valves. However Hytech is also geared to provide one off hydraulic manifolds for systems seen in super yachts or factory production lines. Hytech can also provide original equipment manufacturers (OEMS's) with large runs of hydraulic manifolds, fully assembled with cartridge valves and each individual unit tested before shipping to your assembly plant to be inserted into your machine. At Hytech literally no job is too big or small.
