Why HyPro Manufacture In-House

Here at HyPro, all of our products are designed and manufactured in house. We pride ourselves on their quality, so manufacturing in-house provides a whole host of benefits to us as a business, and to you, our customer.

So, what are the benefits?


As our customer, we know that the quality of your products matters to you as much as it does to us. You need to know the products you order are of the standard you expect and will perform as intended upon use.

By making all of our products in house, we can ensure the quality is perfect.  In-house manufacturing means businesses like us can constantly be tracking our manufacturing process and follow stricter procedures than if we were to outsource this.

We’re always updating our quality control procedures, using the latest measuring equipment, including CMM machines, lasers and other probing apparatus to test all of our equipment before sale and distribution.

Our hydraulic components are top of the range; they’re made to very tight tolerances, often to 2 tenths of a thousandth of an inch, to achieve minimum leakage without sticking.


When it comes to subcontractors, manufacturing in-house also holds other benefits. Since there are a limited number of aerospace contractors who can create tolerances in components so high, they tend to be expensive.

Because we’re able to machine parts on our premises at cost price, we can create products of the highest standard and lowest price for our consumers. Subcontractors would have to add a significant mark-up to products manufactured elsewhere. We’re constantly striving to provide the best quality products at the most affordable price.

What’s more, the manufacturing team have easy access to the design team and can communicate directly about design elements and ensure the parts are made in the most efficient and effective way.

On Time Delivery

One huge bonus of manufacturing our products in house is the ability to meet demand from our customers and react to the market quickly– we’re able to machine what we want to when we want to.

This means we can respond quickly to orders and deliver the most efficient service for our customers.

We are helped by our state of the art machinery which includes pallet loading 5 axis machinery and sliding head lathes. These are capable of running “lights out” and unmanned so production can continue even in the early hours to meet constant demands from OEMs and distributors.


Having machinery on site means we are able to make experimental and prototype components at the whim of our design engineers.  This means we can develop and expand our range quickly to suit new applications for our customers and continually improve our designs.

Hydraulic Projects Ltd – The First 50 Years

Hydraulic Projects Ltd was incorporated by our founder, Dick Hammond, on 14th April 1966.  Following his degree, 15 years in companies like Rolls Royce and Hotpoint and working in air crash investigation, Dick decided to set up on his own and specialise in hydraulic design.

Dick’s first products were a range of hydraulic power units and a hydrostatic transmission system for canal craft.  The latter design allowed engines to be situated in the stern (instead of mid-ships under the table) and its manufacture was licenced to other companies for many years.  During the 1960’s Dick and his wife Irma worked from the Morgan Giles Boat Yard and later the Globe Hall Works in Topsham.

In 1969 Dick was approached by a local manufacturer, Twose of Tiverton, to design and make hydraulic valves for farm equipment.  At 250 relief valves per month, this was a daunting task and the poor economy and unfavourable climate for small business did not help.  With little capital for equipment, Hy-Pro relied on a sub-contractor for the bulk of its manufacture. During this year Colin Willcocks invested in the company, enabling real growth to begin. The business then moved to a former café, the Flamingo (later became M&D Hire), on the Dawlish Road.

By 1976, 50% of turnover was being used to pay the sub-contractors and Dick felt that our future was too dependent on that of other companies.  Dick was keen to invest profits in plant of our own.  With a rented machine shop, Hy-Pro began a planned programme of investment.  Dick’s policy at the time was to buy British, as much for the technical back-up provided as for the quality of the machinery.  These first machines were considered very advanced at the time and included plug board controlled EMI MECH lathes and Moog punch tape controlled vertical machining centres.  John Robberts with his experience from Centrax master-minded the introduction of the machinery.

By the late 70’s the company were producing 5,000 valves every month (including the popular relief valve range developed in the late 60’s), employing 20 people and turning over half a million pounds.  During the 70’s the first range of pumps was designed for the marine autopilot market and the V1790 3/8” ported valve was the first Hy-Pro bankable slice valve.

1982 saw the completion of the present purpose-built machine shop and by 1984 the present office block was completed.

Product improvements and advances followed in the intervening years, including electric solenoid control and the successful V5-60 and V3-100 slice valves.  In 1991, Dick won the prestigious British Design Award (sponsored by the Design Council) for the integral linear hydraulic actuator. A worthy tribute to Dick’s career in hydraulic design.

In July 1995, Mike Humpershon was appointed Managing/Sales & Marketing Director and in 2001 the new pump assembly building was completed in anticipation of increasing demand from Raymarine and the possibility of us setting up our own distributorship.  Unfortunately, 2001 proved to be a difficult year with an economic recession and Raymarine elected to build their own pumps under licence.

2002 was a very sad year for Hy-Pro as Dick passed away in June following a battle with cancer.  He has been greatly missed in the ensuing years.  We were fortunate that Colin Willcocks agreed to step in as our Chairman Of The Board to help ensure the continuity of the business.

Mike left the company in early 2003 and John Robberts and Elaine Slater were appointed as joint CEOs .  Alan Wilson became Sales Director later the same year. On John’s retirement in 2010, Elaine continued as MD.  The Willcocks family purchased the remaining Hammond shares from Dick’s daughters, Lisa and Anna, in 2014.  We are fortunate to include John, Irma, Lisa and Anna in our extended family and we are now privileged to have Colin’s sons, James and Ben on the Board.

Dick would have been proud to know that we are still developing new hydraulic valves in 2016.  His original pumps were re-vamped by Barry Wynn and by commonising parts, reducing costs and producing a 1 litre version, we were able to win back the volume Raymarine work in 2014.  The award winning actuator, with reduced backdrive, has also come into its own through Garmin’s patronage and Hy-Pro is now embracing electronic technology with the new radio remote  (designed by our own Ben Willcocks).  The company continues to regularly invest in cutting edge machinery and technology and we have come a very long way since Dick’s first pencil drawings.

Today we are pleased to say we are still working closely with customers from the early days, such as Teagle Machinery in Cornwall, and that our sales portfolio continues to grow.  We are now developing a network of distributors for both control valves and the marine industry, including distributors in Chile and South Africa.  With new products on the way, excellent quality, reliable delivery, sound investment and competitive prices , we look forward to the next 50 years.

A Beginners Guide to EMC Compliancy

What is EMC compliancy?

EMC (ElectroMagnetic Compatibility) testing is the process in which electrical devices are tested to ensure they do not emit a large amount of electromagnetic interference. These interferences are known as radiated and conducted emissions, and there are tests to prove the quality of both.

This is to establish that any device used or manufactured by us functions as expected around other electromagnetic phenomena, and vice versa.

The Electromagnetic Compatibility Regulations 2006 set out the regulations and standards to which electromagnetic equipment must be held.

This is to be certain electromagnetic disturbance does not reach levels that would prevent telecommunications, radio and other equipment from working properly, and to cement the equipment’s immunity from these effects also.

Why is EMC Testing Important?

Untested electromagnetic equipment can interfere with navigational equipment.

This could have dangerous implications to your craft whilst at sea, on a small-scale interfering with the ultrasound frequencies of fish finders, and on a larger scale affecting the radar, compass and transmissions on military sea craft.

Similarly, untested equipment can itself be affected by other equipment.

All the Hy-ProDrive marine pumps we manufacture are tested to the EMC Navigational standard  BS EN 60945:2002 (DC) for radiated and conducted emissions.

Radiated Emissions Testing

Radiated emissions testing measures the electromagnetic field strength of any unintentionally generated emissions. The overall purpose of radiated emissions testing is to measure the susceptibility of your device to surrounding electromagnetic interference.

So how to EMC labs test this? The device will be placed in a ‘semi-anechoic chamber’, or a shielded metal room, with an antenna directed at it.

This reduces the force of background radio signals, making it easier for the antenna to pick up the signals coming from your product in comparison to background emissions which are kept at a minimum.

This increases the chances of the final readings being considered quantifiable and accurate data.

Conducted Emissions Testing

Conducted emissions testing measures not the emissions the device itself creates, but rather the electromagnetic energy conducted out of the device, such as along any connecting cables like power, signal or data cables.

To reduce the amount of interference a device can have on a power supply, the emission levels are measured to ensure they comply with the limits specified by regulatory bodies.

The interference range tested is typically anywhere between 9kHz to 1GHz.

A LISN (Line Impedance Stabilization Network) will be placed between the equipment under test and a power source to isolate the radio frequency signals from the power source. It will also measure the radio frequency from the device.

Hy-ProDrive Pumps For Marine Autopilots

Hy-ProDrive Pumps (reversing and constant running) and combined actuator units will not affect electronic navigational equipment and will not be affected by other electrical devices.

Our products have undergone rigorous testing to EN 60945:2002 by an approved test house to verify their safety and compliance with UK and EU laws. Why not browse our selection?
