Our Brushless Constant Running Pump

Hy-Pro has recently developed a ‘brushless constant running pump’ that is compatible with large yachts and other commercial craft.

The specialist pump offers a more reliable alternative, requiring less maintenance and offering increased performance. Read on to find out more information about why this pump could be much more beneficial compared to some of the other models out there.

What is a Brushless Constant Running Pump?

The brushless DC motor was designed by Hy-Pro specifically for marine autopilot applications, particularly in the large commercial boat market.

It is used for marine applications such as Trawlers and other commercial craft as well as some larger yachts, and is used to power the hydraulic steering system when the autopilot is in use.

A brushless motor means there is very little ongoing maintenance needed, as the pump is brushless the motor is controlled electronically. This gives us new options for performance moving forward.

The heavy vessels within ordinary hydraulic pumps require a lot of power to steer the vehicles. However, the new and innovative design of the Brushless Constant Running Pump goes against this rule. Instead of using a large DC motor, this pump runs continuously in one direction whilst a solenoid switches the hydraulic flow port and starboard – this saves the crew members having to manually steer the vessel.

For example, fishing boats can be at sea for many hours and the autopilot can be set to run a course or a pattern, this will allow the full crew to be on deck and working on other tasks.

How Does the Pump Work?

The hard-over time is set via the speed control and the steering action is achieved by switching a damped heavy duty double-acting solenoid valve.

The motor and precision gear pump is protected by a pre-set relief valve and check valves with toughened components, these positively lock the steering on course.

The pump has been developed for compatibility with both single and twin ram systems within the boat’s hydraulic steering. The specialist design is also suitable for unbalanced rams.

A ram, sometimes known as a steering cylinder is a critical part within the hydraulic steering system. Choosing the right ram is important to ensure the boat’s steering operates correctly and efficiently.

The brushless pump has also been designed to work alongside pressurised reservoir systems. This component holds the hydraulic fluid in a convenient part of the system and sustains any excess fluid needed.

What is the Pump Made?

Our pump has been integrated with flow output options and a compact construction. This aids in the pump’s durability and longer life span for functioning the steering of marine applications.

Our product has been made from aluminium and a large amount of copper, giving it good bearing properties and also a protective coating for harsh marine environments.

What are the Benefits?

The design consists of built-in overload protection and requires zero maintenance from the user.

In comparison to other models, the brushless motor has a much lower power consumption making it highly efficient. With 12V and 14V options available, this motor is an extremely heavy-duty alternative to others on the market.

This design could potentially replace the PC30 and PC45 in the future due to its convenience working alongside many other components and its futuristic design.

The integral speed control and relief valve also benefits its performance and contributes to a quieter operation.

This pump could be available as early as next year, so make sure you stay tuned for more updates on this pump.

A Brief History of Hydraulics

Using fluid to generate movement within different machinery has been around for thousands of years. The uses of water power dates back as far as Ancient Egypt and it is still used to this day.

Hydraulic power is now all around us and is used in everyday life, powering many of our vehicles and even everyday objects like dishwashers.

Early Discovery

The first evidenced example of hydraulic power is the Perachora wheel, invented in 3rd century BC. The wheel presents one of the simpler models, and this provides an example of using the movement of water to generate power. Many historic entrepreneurs have elaborated on this invention and gradually made hydraulics more and more advanced over time.

In Rome, as early as 25 BC, water was used to power mills that generated the production of flour, stone and timber. It was even used in ‘hushing’, which was the process of extracting tin from lead ores. When people began to build more knowledge on the power of hydraulics this process was then converted into ‘hydraulic mining’ which was particularly helpful within the Californian Gold Rush in the mid-1800s.

The discovery of hydraulics initially began with a French mathematician and physicist named Blaise Pascal. Pascal’s Law was his dominant finding, and this explored the ideals that “pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid such that the pressure variations remain the same”. This law provided a template for the more advanced findings that took place later on in the next century.

Daniel Bernoulli later generated Bernoulli’s principle in 1738, which outlines the behaviour of fluids in various conditions of flow and height. This was particularly helpful for the development of high-pressured water pipes that relied on steam-driven pumps and mills to permit power over long distances.

While this finding was extraordinary at the time, electricity was proven to be more convenient and led to the evolution of combining both electricity and hydraulics to create a more efficient method of power.

Hydraulic Power

Towards the end of the eighteenth century, the hydraulic press came into creation. In 1795, Joseph Bramah used the knowledge sourced by Pascal’s Law for the invention of the hydraulic press.

This hydraulic press provided a pathway for the manufacturing of objects using printing presses, cranes and different forms of machinery.

After a short period of time, the Americans combined this knowledge with their understanding of electricity to generate hydro-power. It was around this point that hydraulic power plants began to be built.

In the late nineteenth century, the first hydro-power scheme came about, William George Armstrong was the founder of this idea, however he decided shortly after that this wasn’t the most efficient way to harness energy. Instead, he began designing the rotary engine, powered by water. Unfortunately, this engine was also unsuccessful and not many people showed interest in his design.

Following this idea, determined to construct an efficient and successful form of hydro-power, Armstrong took upon redesigning the engine and created the piston engine instead.

The piston engine led to the growing development of the hydraulic power-pipe networks. These networks carried power across various locations from one main power source via the movement of water. This was particularly successful in powering cranes across Britain and even in other countries like Switzerland.

Armstrong’s invention had proven to progress much further than any other hydraulic invention, however, there was still a lot of room for improvement. Eventually they realised that H2O was a basic element to persist in hydro-power and in fact oil was more suitable. Some of the key benefits that led to this discovery were that oil proves to be a lot less susceptible to evaporation when operating a machine. Also, a non-corrosive type of oil would be able to perform a lot better, without damaging the machine.

The Use of Hydraulics Today

The rapid evolution of hydraulics has led to a robust and efficient form of hydro-power that we still use today.

This system provides up to ten times more power than an electric motor, making it extremely helpful when lifting and moving heavy objects. The precise mechanics make it a safer alternative than electricity alone and therefore it is better for using around workers and people.

This list of progressive benefits has led to the popularity of hydraulics and its large number of uses within construction, shipping and manufacturing.

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.
