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 1800 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 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 by email at

In Control With Hyspecs

Hydraulic Valve: HS9508Welcome to the first Hydrafile for 2013. 

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.

SAFEX(TM) Valve Test Video, Hardcopy/CD Pricelist, HydraForce i-Design CD

Hydraulic Specialties SAFEXTM valves are designed to be mounted directly to the boom and/or the stick (arm) cylinders of hydraulic excavators. With the correct installation and adjustment these valves prevent uncontrolled lowering of the boom/stick cylinders in the event of a hose burst, thereby becoming part of the load holding and lowering system designed to comply with AS 1418.8 / ISO 8643.

To check compliance with the above standards the SAFEXTM valve was tested on an excavator to simulate a hose burst. A ball valve connected to tank was fitted in the hose going to the boom cylinders. With the test load suspended the ball valve was opened to simulate a hose burst and the boom drop speed measured to ensure that it did not exceed 10mm/sec. For the next test the ball valve was closed and the operator moved the joystick to lower the load and the speed was measured. Then the ball valve was opened, again simulating a hose burst, and the lowering speed was measured to ensure the speed had not increased more than 100%.

We filmed this test with OSH in presence, utilising a Cable Price excavator. The valve passed the test and has been confirmed to comply with the required standards.
