Webtec - Press Release

Hydraulic Specialties Ltd - HYSPECS, is very proud to announce their appointment as Sole Agents for Webtec in New Zealand.Webtec Logo

Webtec are specialist manufacturers of hydraulic measurement and control products helping to improve the productivity of heavy machinery.

In 1985 Britest Equipment Co Ltd were appointed as the sole NZ Agents for Webster Instruments (now Webtec), covering the importation, sales and service throughout the country. John Best, the proprietor of Britest, has continued with this operation for these past 30 years.

Since informing Webtec earlier in the year of his wish to retire, Webtec have been reviewing their options and chosen a new agency agreement for the New Zealand market. Hyspecs are proud to have been chosen as the New Sole Agents for Webtec in New Zealand.

With our appointment, Hyspecs would like to assure Britest's customers that they will receive the same exceptional personal service that they enjoyed in the past. Hyspecs would also like to thank John for agreeing to be on hand to share his knowledge during this transition. John has been passionate in his support of Webtec products, Hyspecs share this passion and believe the Webtec range of testing equipment will compliment the existing range of Hydraulic equipment that Hyspecs currently offers.

Hyspecs will, continue to supply the same Webtec stock as Britest has offered in the past, along with Hyspecs next working day delivery and 24/7 support.

Check Pressure Control Devices

Visually check that pressure control devices have not been tampered with. Look for vibration or pulsation in the pressure line of the pump or motor, with erratic machine movement.

Over pressurisation can lead to costly mechanical failure in pumps, motors, cylinders and valves.

Running systems at under optimum pressure, while less likely to induce failure, can cause system to operate less efficiently. Uncontrolled decompression, thermal expansion or back flow through check valves can cause pressure spikes.

For further information and advice please call us on 0508 497 732 and talk with a sales engineer or email

Oil Reservoir - Space Saver

When you have a big pump you need a big Oil Reservoir right? Wrong.VVR-Duo -02

Standard Oil Reservoirs add weight, they increase the size of your hydraulic System and they also increase the risk of environmental contamination, but there is another option.

Hyspecs in Melbourne recently assisted a customer who wanted a hydraulic system that would operate underground. They wanted a lighter, smaller and environmentally responsible hydraulic system. Hyspecs were able to supply this customer with a Variable Volume Oil Reservoir (VVR) which met all their needs. We have eliminated the need for a 100-150L reservoir by utilising a 7litre VVR. This resulted in huge savings in oil, space, weight and ongoing operating costs while also reducing the environmental impact of a possible oil leak.

To see a VVR in action watch the video - Cylinder operating with Variable Volume Reservoir (VVR)

Test Your Skills Competition Result

Thank you to all of those who entered the Hyspecs "Test Your Skills" competition. We had heaps of correct entries but there can only be one winner...

Congratulations to our winner Ross Shultz from Active Engineering Solutions Ltd.

Answer : The new pump was installed with the pressure compensator at the factory setting, which was higher than the system relief valve setting. Whenever the directional control valve is in the centre position full pump flow is relieving across the system relief valve. Depending on the duty cycle of the cylinder this can cause rapid heating of the oil as most of the electric motor power is going into heat.

Stay tuned as we may have another competition in the very near future!

Test Your Skills Competition

A pressure compensated piston pump was leaking excessively after many years of service and a replacement was ordered. Before fitting the new pump the oil and filter element was replaced and existing valves were checked for correct settings. The new pump was started up and it was confirmed to be producing sufficient pressure and the cylinder was cycled a few times before shutting down the powerpack. The next day production started and the hydraulic system overheated after 30 minutes of operation - why?

Send us your answer by 30th July 2015, to be in the draw for a Stanley Thermos flask. All entries qualify (Hyspecs Staff excluded). Answer will be published next Hydrafile. Click here to email us your answer.

Energy Saving Tip: Oil Viscosity Grade

Clean hydraulic oil of the correct viscosity grade and running at optimum temperature will ensure your hydraulics work efficiently. The working viscosity range for most hydraulic systems is 15 to 100 cSt with 20 to 40 cSt being the optimum. For hydraulic oil we generally use the ISO Viscosity Grade classification which is the kinematic viscosity of the oil at 40'C. For lower working temperatures ISO VG 22 or 32 oil is recommended and for higher working temperatures ISO VG 46 or 68 oil is ideal. Hydraulic oil that's too viscous requires extra power to overcome pressure losses, oil that's too thin causes premature wear and excessive internal leakage.

For further advice speak to a Hyspecs Engineer on 0508 497 732.

Hydraulic Oil Testing Kits

Castrol oil sample analysis kits are available from Hyspecs.

The $72 + GST list price of the kit includes postage to Castrol Christchurch and the test cost. Castrol offer a 24 hour turn around on the sample and results can be e-mailed directly to you.

You can also request a 6 hour turn around if it is an emergency.

Hydraulic system failures relate either directly or indirectly to particulate contamination of hydraulic oil. Critical hydraulic systems benefit greatly from a range of specific tests to check for cleanliness and system component wear.

Hytech - Design Doubled

Hyspecs manufacturing division, Hytech have doubled their design capabilities, and reduced their lead times.

Hytech welcomes to the team - Wendy Roberts - CAD Manifold Design Engineer.

Due to increased demand for Hydraulic manifolds, Hytech recruited Wendy as an additional designer to assist Steven Zhou with manifold designs at Hytech.

Wendy has been designing manifolds for 19 years since graduating from Coventry University in the UK with a bachelor of Mechanical Engineering. Wendy worked for UK based family business Integrated Hydraulics for 15 years (this business was bought out by Eaton), she then moved on to Hydraforce (UK) for 4 years before joining Hytech April 2015.

Hytech have been looking for ways to reduce turnaround for the manufacture of their Hydraulic Manifolds. 

This review has involved

  • Matching jobs with similar settings to reduce setting times
  • Tracking setting times
  • Tracking machine hours
  • Looking at the features of the CNC machines to get the most out of these machine
  • Repeat orders can now be managed much more quickly
  • Improved finishing with Nicol plating on all manifolds. The thickness of the plating customised to suit different working environments for longer life.
  • Working towards ISO 9000 acreditation to ensure consistency and quality of products

The results of this continual review process have been

  • Improved turn around in design
  • Increased machine time
  • Improved turn around in production

Mobile Hydraulic Service Centre

Taupo Trailer Montage Web

Hyspecs is pleased to announce the arrival of the Mobile Hydraulic Service Centre otherwise known as "The Service Trailer". 

Based in Taupo this trailer is available to carry out Hydraulic Servicing and repairs at our customers sites. This means that equipment and plant has less downtime during maintenance and repairs.

Hyspecs purchased a trailer, the Hyspecs Chirstchurch service team set out to convert this trailer into a workshop. Johan from Hyspecs Taupo then took over with Ross to put in a Hydraulic Test bench, a Hose press, Welder, Compressor and parts storage. This trailer obviously can not have everything but will be able to help in a number of situations.

As this trailer is mobile we can use this anywhere in the country that is accessible by road should it be required. The trailer has already been used for a number of jobs and with bookings for planned service work. Customers have found this to be a very convenient service. Please call Hyspecs to find out more 0508 497 732 

When Should You Change A Filter?

OMT Tank Top ReturnSpin OnAFilters should be checked at least once a month and elements changed as per the indicators, or every 2000 hours of operation, or every 6 months whichever comes first. Fluid condition should be checked at regular intervals to maintain optimum component life.

Most hydraulic failures and premature wear of components are due to oil contamination.

Hydraulic systems subject to severe service cycles, very high pressures, extreme temperatures or containing piston pumps, proportional and servo valves are more contaminant sensitive and require finer filter media. Hyspecs recommends all filters have visual or electrical pressure differential indicators fitted so you know when to replace the filter elements. An oil particle analysis to ISO 4406 is the best way to determine your filtration effectiveness and the health of the hydraulic system. Hyspecs has oil sample kits available as well as optical oil particle monitors that can be permanently installed on your machine and interfaced with your control system.

Call us here at Hyspecs now for filters or book a service on 0508 497 732.
